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...

A competing theory to 'dark energy' suggests the universe has different time zones

By
A competing theory to 'dark energy' suggests the universe has different time zones Recent cosmological research has introduced alternative theories to dark energy, suggesting that variations in the flow of time across different regions of the universe could account for the observed accelerated expansion. These theories propose that the universe may have "different time zones," where time progresses at varying rates depending on the density of matter and gravitational energy in a given region. Alternative Theories to Dark Energy 1. Timescape Cosmology Concept : Proposed by physicist David L. Wiltshire, timescape cosmology posits that the universe is not homogeneous; instead, it consists of regions with varying matter densities. This inhomogeneity leads to differences in the passage of time between dense regions (like galaxies) and vast, empty voids. Gravitational Time Dilation : In areas with higher matter density, stronger gravitational fields cause time to flow more ...
