Redeeming India’s Nuclear Power Promise: A Clean Energy Imperative for 2047

By
Introduction: A Nuclear Vision for Viksit Bharat@2047 As India marches toward its ambitious goal of becoming a developed nation by 2047, energy security stands as a pivotal pillar in the vision of Viksit Bharat . Amid the global climate crisis and rising energy demands, nuclear power has re-emerged as a compelling solution. India’s commitment to achieving 100 GW of nuclear power capacity by 2047 is both visionary and necessary—but achieving this requires a strategic shift in policy, participation, and international cooperation. While India’s nuclear energy sector has traditionally been a tightly controlled domain under government monopoly—primarily led by the Department of Atomic Energy (DAE) and Nuclear Power Corporation of India Limited (NPCIL) —it is now imperative to welcome private sector investments and foreign partnerships. A reformed nuclear ecosystem can unlock the full potential of atomic energy as a clean, reliable, and scalable contributor to India’s net-zero aspiration...

IN-SPACe CANSAT & Model Rocketry India Student Competition 2024–25: A Giant Leap for Student Innovation

By
In a remarkable step towards strengthening India’s STEM education framework, the Astronautical Society of India (ASI), in collaboration with the Indian Space Research Organisation (ISRO) and the Indian National Space Promotion and Authorization Center (IN-SPACe), has launched the IN-SPACe CANSAT and Model Rocketry India Student Competition 2024–25 . This unique competition is crafted for undergraduate students across India, providing them with an opportunity to engage in experiential learning through the design, fabrication, and launch of CANSATs—can-sized satellites—using model rocketry platforms. The event held on June 14, 2025 , in Tamkuhi Raj, Kushinagar, Uttar Pradesh , was not a full-fledged rocket launch carrying an actual payload. Instead, it served as a critical site and systems validation test in preparation for the upcoming national student competition. This test focused on ensuring the readiness of launch site infrastructure, safety protocols, telemetry systems, and track...

CERN Collider Breakthrough: Why the Universe Prefers Matter Over Antimatter

By
Introduction: A Universe Built on Bias? In a groundbreaking discovery at CERN, scientists have finally found concrete evidence that the laws of physics differ for matter and antimatter . This observation could solve one of the most perplexing mysteries in cosmology — why our universe is made almost entirely of matter , even though the Big Bang should have produced equal amounts of matter and antimatter . This new clue comes from experiments conducted at the Large Hadron Collider (LHC) , the world’s most powerful particle accelerator, located near Geneva, Switzerland. The finding marks a pivotal advancement in the field of particle physics , with implications for the Standard Model , CP violation , and our fundamental understanding of the origin of the universe . What is Matter-Antimatter Asymmetry? At the dawn of the universe, matter and antimatter were created in equal proportions. Each particle of matter has an antimatter counterpart — with the same mass but opposite charge. Whe...
