  • [12th Februrary 2026] The Hindu OpED: The CPI base revision exercise measures a slice of life

    PYQ Relevance[UPSC 2023] Most of the unemployment in India is structural in nature. Examine the methodology adopted to compute unemployment in the country and suggest improvements. Linkage: Unemployment and inflation are core GS-3 macro indicators influencing growth and monetary policy. Just as CPI base revision affects inflation measurement, unemployment estimates depend on survey methodology (PLFS), shaping policy credibility and reform design.

    Why in the News?

    The Ministry of Statistics and Programme Implementation (MoSPI) has decided a comprehensive exercise for revision of the base year of Gross Domestic Product (GDP), Index of Industrial Production (IIP) and Consumer Price Index (CPI) to enhance their relevance, accuracy and international comparability. The proposed new base year for the GDP and IIP is 2022-23, and for CPI the proposed base year is 2024. The revision of CPI will be done using findings from the latest Household Consumption Expenditure Survey (HCES). The revision recalibrates expenditure weights to reflect structural shifts in consumption patterns over the past decade. Since CPI is the anchor for inflation targeting and monetary policy, changes in its composition directly influence measured inflation and policy response. The exercise also gains significance after gaps in consumption data, making representativeness and credibility central concerns.

    What is CPI and Why is it Important?

    Consumer Price Index (CPI) measures the average change over time in the retail prices of a fixed basket of goods and services consumed by households. It reflects retail inflation and serves as the nominal anchor under India’s inflation targeting framework.

    1. Retail Inflation Measure: Tracks price changes at the consumer level across goods and services.
    2. Inflation Target Anchor: Forms the basis of RBI’s flexible inflation targeting framework.
    3. Cost-of-Living Indicator: Reflects purchasing power of households.
    4. Policy Benchmark: Guides interest rate decisions, wage revisions and welfare indexation.
    5. Macroeconomic Signal: Influences investor expectations and economic outlook.

    Why Was Base Year Revision Necessary?

    1. Outdated Consumption Weights: 2012 basket no longer reflects current spending behaviour.
    2. Structural Economic Shift: Expansion of services sector and urbanisation since 2012.
    3. Consumption Diversification: Rising share of telecom, transport and service expenditures.
    4. Reduced Food Share: Relative decline in food and clothing weight in total expenditure.
    5. Data Discontinuity Concern: Delay in updated consumption data affected representativeness.

    How Does the CPI Basket Reflect Structural Changes in Society?

    1. Shift from Goods to Services: Higher expenditure on communication, transport and service-based consumption.
    2. Urbanisation Impact: Changing food habits, mobility patterns and housing expenditure.
    3. Changing Aspirations: Rising discretionary spending relative to subsistence consumption.
    4. Technology Integration: Inclusion of modern consumption categories such as telecom services.
    5. Rural-Urban Convergence: Updated survey captures evolving rural consumption patterns.
    6. Declining Engel Ratio: Reduced proportional spending on food indicates income progression.

    What Are the Macroeconomic Implications of CPI Base Year Revision?

    1. Inflation Recalibration: Weight changes can alter headline and core inflation trends.
    2. Monetary Policy Adjustment: RBI policy stance depends on CPI trajectory.
    3. Real Interest Rate Impact: Changes in measured inflation affect real returns.
    4. Fiscal Planning Effect: Influences subsidy indexation and welfare transfers.
    5. Market Signalling: Alters inflation expectations in financial markets.
    6. Credibility Enhancement: Strengthens confidence in official inflation statistics.

    Conclusion

    CPI base revision updates inflation measurement to reflect contemporary consumption patterns. It strengthens accuracy, improves macroeconomic signalling and supports effective monetary policy.

  • Taxpayer base more than doubled in the last decade

    Why in the News?

    India’s direct tax system has recorded sustained expansion in both individual and non-individual taxpayers. India’s taxpayer base has more than doubled over the last decade, with individual taxpayers rising from 3.26 crore in AY2013-14 to nearly 7.26 crore in AY2024-25, while the total base expanded to about 4.8 crore. Simultaneously, the cost of collecting direct taxes declined to 0.41% in FY2024-25 (provisional), the lowest in available data.The increase reflects administrative reforms, digitalisation of filing systems, and structural strengthening of compliance mechanisms.

    What is the scale of expansion in the taxpayer base?

    1. Individual taxpayers: Increased from 3.26 crore (AY2013-14) to nearly 7.26 crore (AY2024-25), more than doubling in a decade.
    2. Total taxpayer base: Expanded from about 2.9 crore in AY2013-14 to nearly 4.8 crore in AY2024-25.
    3. Growth rate: Registered a CAGR of approximately 5% over the period.
    4. Peak annual growth: 7.89% CAGR observed during the period.
    5. Pandemic disruption: Growth slowed sharply in FY2020-21 due to COVID-19-related economic disruption.
    6. Recovery phase: Growth rebounded in subsequent years, indicating durability of expansion.

    How has the composition of taxpayers evolved?

    1. Dominance of individuals: Individual taxpayers continue to dominate the system.
    2. Non-individual taxpayers: Includes firms, companies, LLPs, Association of Persons (AOPs), Body of Individuals (BOIs), local authorities, and artificial juridical persons.
    3. Steady growth in non-individuals: Growth remained more stable compared to individuals, without major pandemic volatility.
    4. Broader base expansion: Evidence suggests increasing formalisation across business entities.

    What institutional changes supported this expansion?

    1. Digital filing systems: Increased reliance on online return filing.
    2. Pre-filled returns: Reduced compliance burden and errors.
    3. Expanded third-party reporting: Strengthened information matching.
    4. Reduced face-to-face interactions: Enhanced transparency and minimised discretion.
    5. Compliance friction reduction: Enabled smoother onboarding of taxpayers.
    6. Administrative strengthening: Indicated by consistent year-on-year improvements.

    What does the cost of collection indicate?

    1. Declining cost of collection: Reduced from 0.61% of gross direct tax collections (FY2000-01) to 0.41% (FY2024-25 provisional).
    2. Lowest in available data series: Reflects sustained administrative efficiency.
    3. Pandemic spike: Temporary rise in FY2020-21 due to disruptions.
    4. Post-pandemic correction: Returned to declining trajectory.
    5. Efficiency gain: Indicates improved revenue mobilisation per rupee spent.

    What does this imply for fiscal capacity and governance?

    1. Structural strengthening: Evidence suggests durable expansion, not a one-time compliance surge.
    2. Formalisation of economy: Broader cross-section of taxpayers entering formal net.
    3. Revenue resilience: Supports fiscal planning and long-term budgeting.
    4. Administrative modernisation: Reflects digital governance success.
    5. Compliance culture: Indicates deeper tax participation.

    Conclusion

    The sustained expansion of the taxpayer base alongside declining cost of collection signals structural strengthening of India’s direct tax system. The evidence suggests institutional reform, digitalisation, and broader formalisation have enhanced fiscal resilience and administrative efficiency.

    PYQ Relevance

  • Carbon Capture to Drive India’s Green Steel Transition

    Why in the News

    The Prime Minister shared an article highlighting the role of Carbon Capture, Utilisation and Storage in decarbonising India’s steel sector, aligning with India’s Net Zero 2070 commitment.

    India’s Steel Sector at a Glance

    • India is the world’s second largest crude steel producer.
    • Production: Around 152 million tonnes in FY 2024-25.
    • Target under National Steel Policy 2017:
      • 300 million tonnes by 2030-31
      • 500 million tonnes by 2047

    Note: Steel production contributes nearly 10 to 12 percent of India’s total greenhouse gas emissions due to coal based blast furnace and direct reduced iron routes.

    What is CCUS

    Carbon Capture, Utilisation and Storage involves:

    • Capturing carbon dioxide from industrial processes
    • Utilising it for industrial applications or
    • Storing it underground to prevent atmospheric release

    It helps address process emissions that cannot be eliminated through energy efficiency or renewable power alone.

    Government Measures

    • Green Steel Taxonomy:Defines emission intensity benchmark: Less than 2.2 tonnes of CO2 equivalent per tonne of finished steel
      • Introduces star rating framework
    • National Green Hydrogen Mission: ₹455 crore allocated for pilot projects in steel sector

  • Global warming and pollution are stripping vibrant colors from nature

    Why in the news?

    A 2024 study in Ecology and Evolution reports that insects such as ladybirds and dragonflies in temperate regions are turning lighter due to frequent heatwaves. Over half of the world’s oceans have become greener in the last two decades. Forests are turning browner. Coral reefs, including those in Gulf of Mannar and Lakshadweep, are facing repeated bleaching. These visible colour changes reflect large-scale climate stress on ecosystems.

    What is Ecological discolouration?

    Ecological discolouration refers to measurable changes in the natural colour patterns of ecosystems caused by environmental stress. It can be caused by:

    1. Pigment Alteration: Changes in the concentration or type of biological pigments like chlorophyll (green in plants/algae), melanin (darker tones in animals), and carotenoids (yellow/orange) often due to UV exposure or nutrient shifts.
    2. Symbiotic Loss: The most prominent example is coral bleaching, where corals expel their colorful symbiotic algae (zooxanthellae) due to thermal stress, leaving behind a white skeleton.
    3. Species Composition Shifts: The replacement of native species with others such as invasive toxic dinoflagellates or algae blooms can physically change the color of water bodies or forests.
    4. Biogeochemical Disruptions: Alterations in cycles (like nitrogen or carbon) can lead to soil or water changes, such as the formation of dark terra preta soils or anaerobic “black spots” in marine sediments.

    Functions in Ecology

    1. Early-Warning Indicator: Visible fading or darkening provides an immediate signal of ecosystem instability.
    2. Stress Proxy: It serves as a measurable metric for temperature stress, chemical pollution, and habitat degradation.
    3. Biodiversity Marker: Mapping color variations across a landscape helps scientists track the loss or gain of biodiversity in real-time

    How is climate change altering ocean colour?

    1. Ocean Greening: Over 50% of global oceans have become greener in the last two decades.
    2. Algal Proliferation: Greener waters indicate increased algal presence.
    3. Sunlight Blockage: Algae reduce water clarity and limit sunlight penetration.
    4. Oxygen Depletion: Decomposition of algal blooms lowers oxygen levels, harming marine organisms.

    What is Coral bleaching?

    It is when corals expel the colorful, nutrient-providing algae (zooxanthellae) living in their tissues due to stress, turning them white, but they aren’t dead yet. Prolonged stress from rising ocean temperatures (climate change) or other factors like pollution causes them to starve and potentially die, leading to reef ecosystem collapse.

    What happens during bleaching?

    1. Stress triggers expulsion: Corals are stressed by changes in water temperature (usually warming), light, salinity, or nutrients.
    2. Algae leave: Stressed corals expel the symbiotic algae (zooxanthellae) that live within them and provide food and color.
    3. Coral turns white: Without the algae, the coral’s transparent tissue reveals its white skeleton, making it appear “bleached”.

    How does coral bleaching reflect marine ecosystem stress?

    1. Indian Reef Impact: Bleaching reported in Gulf of Mannar, Palk Bay, Lakshadweep, Andaman & Nicobar Islands.
    2. Thermal Stress Mechanism: Corals expel symbiotic algae under heat stress, turning white.
    3. Mortality Risk: Repeated bleaching increases coral death probability.
    4. Ecosystem Disruption: Coral reefs support marine biodiversity and fisheries.

    What does forest browning indicate?

    1. Vegetation Stress: Forests are turning browner due to climate stress and habitat degradation.
    2. Pigment Reduction: Chlorophyll loss reflects reduced photosynthetic efficiency.
    3. Habitat Instability: Browning signals declining ecosystem resilience.

    How are insects adapting through pigmentation change?

    1. 2024 Study Finding: Ladybirds and dragonflies in temperate northern regions are becoming lighter.
    2. Heatwave Response: Lighter pigmentation reflects sunlight and prevents overheating.
    3. Melanin Composition:
      1. Eumelanin: Produces brown/black shades; absorbs more heat.
      2. Pheomelanin: Produces yellow/red tones.
    4. Reproductive Impact: Pigmentation shifts may affect mating patterns and reproductive timing.

    What historical example shows climate-driven colour adaptation?

    Climate-driven colour adaptation refers to the process where, in response to changing environmental conditions (temperature, humidity, UV radiation) caused by climate change, species evolve or plastically alter their body or flower pigmentation to improve survival, thermoregulation, or reproduction.

    1. Industrial Revolution Case: Soot darkened tree bark.
    2. Peppered Moth Shift: Dark variants survived due to improved camouflage; light variants declined.
    3. Adaptive Principle: Species become darker in colder climates and lighter in warmer conditions. 
    4. Butterflies (Colias meadii): A long-term study (1953-2012) showed that wing melanization in these butterflies decreased with increasing temperature, but this pattern varied by region, showing higher melanism in the hotter southern USA.

    How does deforestation affect species colour diversity?

    1. Amazon Study (Biodiversity and Conservation): Deforestation reduces bright colour displays in butterflies.
    2. Habitat Disturbance Effect: Disturbed forests show less diverse butterfly palettes.
    3. Regeneration Signal: Naturally regenerated Amazon forests show improvement in colour diversity.

    What are the ecological implications?

    1. Camouflage Disruption: Alters predator-prey balance.
    2. Thermoregulation Shift: Pigmentation change modifies heat absorption.
    3. Biodiversity Indicator: Colour variation reflects ecosystem health.
    4. Systemic Climate Signal: Large-scale discolouration indicates long-term environmental stress.

    Conclusion

    Ecological discolouration represents a visible manifestation of climate-induced ecosystem stress. Ocean greening, forest browning, coral bleaching, and pigmentation shifts in species indicate disruption in biological processes and habitat stability. These changes signal declining ecosystem resilience and rising vulnerability to extreme climatic events. Monitoring such colour shifts can function as an early warning tool for biodiversity loss and guide targeted climate adaptation and conservation strategies.

  • A reckoning for India’s aviation sector

    Why in the News?

    India’s aviation sector is under scrutiny following operational failures, rising safety incidents, and declining passenger confidence. This sector is the world’s third-largest domestic aviation market carrying over 350 million passengers annually. The December crisis marked the first large-scale disruption for IndiGo, exposing systemic stress in the country’s largest airline, which controls nearly 60% of the domestic market. Simultaneously, pilot shortages, FDVT violations, high ATF volatility, and congestion at 85+ airports operating beyond capacity have intensified vulnerabilities. The sector faces a structural reckoning as new regional carriers enter an already overstretched ecosystem.

    What is the growth and economic significance of India’s Aviation Sector?

    1. Market Size Expansion: India is the world’s third-largest domestic aviation market, with airports increasing from 74 (2014) to 163 (2025).
    2. Economic Multiplier Effect: Aviation generates over three times economic activity for every rupee invested and supports more than six times employment in allied sectors.
    3. Employment Contribution: The sector supports over 7.7 million jobs, including 369,000 direct jobs.
    4. Traffic Growth: Domestic passenger traffic has grown at an annual rate of 10-12% over the past decade.
    5. Global Integration: India has over 116 bilateral Air Service Agreements, strengthening international connectivity.
    6. Industrial Linkages: Aviation drives FDI inflows, technology transfer, and growth in aircraft manufacturing, MRO, and ground handling services under Make in India.

    Why is India’s aviation sector facing operational stress?

    1. Scale without proportional capacity: Carries 350+ million passengers annually with over 840 aircraft, but expansion has outpaced structural preparedness.
    2. December disruption as stress test: First large-scale disruption affecting IndiGo exposed systemic fragility.
    3. Airport congestion: 85 airports operating beyond capacity; 102 new routes planned under UDAN 2025-26.
    4. Network dependency risk: High route concentration increases vulnerability to cascading delays and cancellations.

    What explains the pilot shortage and regulatory strain?

    1. Pilot-to-aircraft imbalance: India’s ratio remains below global benchmark of 18-20 pilots per aircraft; IndiGo at 14, Air India at 36 (group level including subsidiaries), Air India Express at 15.
    2. FDVT violations: DGCA issued 19 safety violation notices in 2025 citing breaches of flight duty time limitations, lapses in quality assurance, and expired emergency equipment use.
    3. Training pipeline constraints: CPL issuance inconsistent with estimated annual requirement of 7,000 pilots; issuance around 5,700 between 2020-24.
    4. Operational fatigue risks: Regulatory exemptions for scheduling rather than structural hiring reforms.

    How does market concentration amplify systemic risk?

    1. Duopoly structure: IndiGo (63-65%) and Air India group (27%+) together control nearly 90% of the domestic market.
    2. Route concentration: IndiGo dominant on 600 monopoly routes and 200 duopoly routes.
    3. Financial vulnerability: Past airline failures-Jet Airways (2019), Kingfisher Airlines (2012), Air Deccan collapse, Go First (2023-24), demonstrate systemic contagion risk.
    4. Passenger dependency: 60.4% of domestic capacity concentrated under a single carrier.

    How do infrastructure and fuel volatility impact viability?

    1. ATF volatility: Aviation Turbine Fuel priced in U.S. dollars; exposes airlines to exchange rate fluctuations.
    2. High cost structure: ATF remains one of the largest operational expenditures.
    3. Infrastructure bottlenecks: Congested metro airports; Tier-2 and Tier-3 airports underdeveloped despite UDAN push.
    4. Limited hedging mechanisms: Absence of systematic fuel hedging increases cost unpredictability.

    What role do new regional entrants play?

    1. New NOCs (December 2025): Shankh Air, Al Hind Air, and Fly91 approved.
    2. Regional connectivity expansion: Planned routes include Noida International Airport linkages and underserved regions such as Kochi and Shankh Air’s Uttar Pradesh focus.
    3. Deconcentration potential: Entry could reduce excessive dependence on major carriers.
    4. Structural risk persists: New entrants operate in an already capacity-stressed environment.

    Conclusion

    India’s aviation sector has evolved into a strategic growth engine, combining infrastructure expansion, employment generation, and global integration. Sustained capacity augmentation, regulatory strengthening, and balanced regional connectivity will determine whether the sector can translate its rapid growth into long-term economic resilience and inclusive development.

  • Why Manufacturing Growth Has Not Led to Broad Employment

    Why in the News?

    Union Budget 2026 reinforces the existing manufacturing strategy, especially through Production Linked Incentive schemes and customs duty rationalisation. However, analysts note that manufacturing growth has not translated into large scale job creation.

    Core Issue: Growth Without Jobs

    1. Stagnant Share in GDP

    • Manufacturing share remains 14 to 17 percent for decades.
    • Successful industrialisers in East Asia reached 25 to 30 percent before stabilising.
    • Indicates incomplete structural transformation.

    2. Jobs Growth Disconnect

    • Organised manufacturing employs about 1.96 crore workers.
    • Only about 57 lakh jobs added in the last decade.
    • Total manufacturing employment around 5.44 crore, with two thirds in informal units.

    Note: Organised factories are productive but create few jobs. Unorganised units absorb labour but remain low productivity and low wage.

    3. Capital Intensive Expansion

    • Firms rely on automation and capital deepening.
    • Output rises faster than employment.
    • Job elasticity of growth remains low.

    4. Skills Mismatch

    • Firms struggle to find job ready workers.
    • Weak firm level training and apprenticeship ecosystem.
    • Skill programmes poorly linked to industry demand.

    5. MSME Constraints

    • MSMEs contribute 35 percent of manufacturing output and about half of exports.
    • Credit expansion improves liquidity but not productivity.
    • Weak technology adoption, poor supply chain integration, limited scaling.

  • SC tells RBI to bring in stricter checks to stop online frauds

    Why in the News? 

    A Bench led by the Chief Justice of India directed the Reserve Bank of India (RBI) and the Union Government to strengthen safeguards against online financial frauds. The Supreme Court has flagged the siphoning of over ₹52,000 crore between April 2021 and November 2025 through online frauds such as “digital arrests,” calling it nothing short of “absolute robbery or dacoity.” In a sharp judicial intervention, the Court questioned why no alarm is triggered when unusually large sums like ₹50 lakh are withdrawn from a retiree’s account. It has directed the RBI and the Home Ministry to tighten suspicious transaction norms and formally implement Standard Operating Procedures for cyber fraud coordination. The scale of fraud and the Court’s direct push for systemic banking reforms make this a significant moment in India’s cyber-financial governance framework.

    What Triggered the Supreme Court’s Concern?

    1. ₹52,969 crore siphoned (April 2021-November 2025): The Court noted large-scale cyber-enabled frauds, including “digital arrests.”
    2. Characterisation as ‘absolute robbery or dacoity’: The Bench emphasized the severity and scale of financial losses.
    3. Pattern of large withdrawals: The Court questioned why no alert is triggered when ₹50 lakh is withdrawn from a retiree’s account, especially when monthly withdrawals are typically ₹10,000.
    4. Judicial scrutiny of RBI: The Court stated it was time for the central banker to ensure stronger protective mechanisms for depositors.

    Why Did the Court Question Suspicious Transaction Monitoring?

    1. Definition expansion required: The Court stated that the definition of “suspicious transaction” must be broadened.
    2. Banking business model shift: Justice Bagchi noted banks are largely in “business mode,” facilitating swift and seamless transfers.
    3. Digital efficiency aiding crime: Faster transactions enable quick movement of stolen money.
    4. Accountability query: The Bench sought explanation on misappropriation based on official reporting.

    What Directions Were Issued to the Government?

    1. Formal SOP implementation: Directed the Home Ministry to adopt and implement nationwide the SOP issued on January 2.
    2. Inter-agency coordination: Ensures structured coordination in cyber-enabled fraud cases.
    3. Victim identification mechanism: Mandates identification of defrauded parties.
    4. Notification of implementation rules: Ordered formal notification of required regulatory framework.

    What Institutional Mechanisms Are Being Strengthened?

    1. Memorandum of Understanding (MoU): Government finalising MoU for suspect registry sharing.
    2. Data sharing architecture: Facilitates exchange of suspect registry data.
    3. Mule account detection tools: Strengthens identification of accounts used for fraudulent transfers.
    4. Preventive and responsive tools: Supports blocking of fraudulent transactions.

    How Big is the Problem?

    1. Scale of fraud: ₹52,969 crore misappropriated in less than five years.
    2. Targeted vulnerability: Retirees and ordinary account holders vulnerable.
    3. Systemic gaps: Absence of automatic red-flag triggers for abnormal withdrawals.
    4. Judicial intervention: Indicates inadequacy of existing regulatory safeguards.

    Conclusion

    The Supreme Court’s intervention underscores the systemic risks posed by cyber-enabled financial frauds in an increasingly digital banking ecosystem. The scale of misappropriation and the absence of robust red-flag mechanisms reveal gaps in regulatory vigilance and inter-agency coordination. Strengthening suspicious transaction definitions, enhancing data-sharing frameworks, and ensuring proactive oversight by the RBI and enforcement agencies are essential to safeguard depositor trust and preserve financial stability.

    Value Addition

    What is a digital arrest?

    • It is a sophisticated cyber scam where fraudsters impersonate law enforcement (police, CBI, etc.) or government officials to instill fear and extort money or data from victims.
    • It makes the victims believe they are under arrest for serious crimes like money laundering or drug trafficking, often using fake documents, video calls with fake police station backgrounds, and high-pressure tactics to force compliance. 
    • It’s a form of online fraud, not a real legal process, designed to manipulate victims into paying fines or revealing personal information to avoid (fake) arrest, leading to financial loss or identity theft.

  • On gravity’s role on Earth’s journey through space

    Why in the News?

    The article becomes relevant at the start of a new year, as it reflects on Earth’s continuous journey around the Sun at nearly 1,07,000 km per hour. It points out that even at such enormous speed, life remains stable because gravity keeps everything in balance. The piece recalls an important scientific milestone, the rejection of the ether theory in 1887, and pays tribute to Prof. Jayant Narlikar, founder of IUCAA, after his recent passing. It contrasts old beliefs about “aether” with today’s scientific understanding of vacuum and gravitational forces. The striking figures, Earth travelling nearly 1 billion kilometres in a year and about 40,000 kilometres in an hour, highlight how vast this motion is, even though we do not feel it in everyday life.

    What is Gravity?

    1. Gravity is a fundamental, invisible force of attraction that pulls any two objects with mass toward each other. 
    2. Its strength depends on the mass of the objects and the distance between them
    3. Gravity governs both terrestrial and cosmic systems. 
    4. It explains falling objects, planetary motion, and Earth’s stable revolution around the Sun. 
    5. The Earth completes one revolution in 365 days while travelling nearly one billion kilometres annually at high velocity. This motion remains unnoticed due to gravitational balance and absence of resistive friction in space.

    How Does Gravity Function as a Centripetal Force?

    1. Centripetal Mechanism: Gravity acts as the centripetal force pulling bodies towards a centre, ensuring orbital motion.
    2. Bicycle Analogy: Pulling a string tied to a rotating object redirects its motion inward, similar to gravitational pull maintaining planetary orbits.
    3. Planet-Sun Interaction: Earth does not fall into the Sun because forward motion balances gravitational pull.
    4. Universal Application: The same mechanism explains the Earth-Moon system and other celestial rotations.

    Why Do Objects Fall Toward Earth?

    1. Universal Gravitation: Objects fall toward Earth because Earth is the heaviest nearby mass.
    2. Mass Attraction: All objects with mass attract one another.
    3. Everyday Example: Falling bodies move toward Earth’s centre unless acted upon by another force.

    How Fast Is Earth Travelling in Space?

    1. Annual Distance: Earth travels nearly 1,000,000,000 km in one year.
    2. Hourly Speed: Approximate orbital speed equals 1,07,000 km per hour.
    3. Comparative Illustration: A car travelling at 100 km per hour without stopping would take around 1,000 years to cover a comparable distance.
    4. Temporal Perspective: Earth covers nearly 40,000 km in about one hour.

    Why Is There No Friction in Space?

    1. Friction Concept: Friction arises due to surrounding particles resisting motion.
    2. Earthly Examples: Air slows a bird; water resists a fish; road friction stops a car.
    3. Vacuum Condition: Space lacks resisting medium, preventing deceleration of planetary motion.
    4. Energy Continuity: Continuous motion persists without need for refuelling unlike vehicles requiring oil.

    What Was the Ether Hypothesis and Why Did It Fail?

    1. Ether Assumption: Earlier belief held that an invisible material called “aether” filled space.
    2. Michelson-Morley Experiment (1887): Attempted to detect ether; failed to find evidence.
    3. Scientific Outcome: Demonstrated absence of ether, marking a major conceptual correction.
    4. Modern Understanding: Space functions as vacuum without a resistive medium.

    What Is the Significance of Space Studies in India?

    1. Institutional Role: IUCAA in Pune advances astrophysics research.
    2. Scientific Leadership: Prof. Jayant Narlikar contributed to cosmological theories and public science communication.
    3. Recognition: Awarded Padma Vibhushan in 2004.
    4. Public Outreach: Science communication through television series such as “Brahmand.”

    Conclusion

    Earth’s silent, high-speed journey through space is sustained by the precise balance of gravity and motion. What once required speculative ideas like “ether” is now explained through tested scientific principles. By reflecting on these discoveries, and the contributions of scientists like Jayant Narlikar, it reinforces the importance of scientific temper in understanding our place in the universe.
