India’s AMCA Programme Takes Flight: A Stealth Leap into the Future of Air Combat

By
In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative. AMCA: India’s Indigenous Stealth Fighter Dream The AMCA project , spearheaded by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO) , received its l...

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 ...

Quipu Superstructure: The Largest Known Structure in the Universe

By
Quipu Superstructure: The Largest Known Structure in the Universe Introduction Astronomers have discovered the largest known structure in the universe, named Quipu , an enormous superstructure composed of galaxy clusters and cosmic filaments. Key Characteristics Size & Mass : The Quipu superstructure stretches across 1.3 billion light-years . It has a mass of 200 quadrillion solar masses . Composition : Made up of galaxy clusters, filaments, and voids . It belongs to a class of superstructures , which contain multiple superclusters of galaxies. Effects of Superstructures Cosmic Microwave Background (CMB) Disturbances Superstructures like Quipu create fluctuations in the CMB, which is the leftover radiation from the Big Bang . Impact on the Hubble Constant The presence of massive superstructures distorts accurate measurements of the universe’s expansion rate. This causes variations in the calculation of the Hubble Constant , leading to discrepancies in cosmic models. Gravitational...

Manasvi: IIT Delhi’s Bold Step Toward Empowering High School Girls in STEM

By
In a world increasingly shaped by technological advancement, ensuring gender equality in STEM (Science, Technology, Engineering, and Mathematics) is no longer a choice—it’s a necessity. Recognizing this, the Indian Institute of Technology (IIT) Delhi launched a pioneering initiative titled ‘Manasvi’ , a STEM mentorship programme for high school girls . The programme, unveiled in New Delhi today, is spearheaded by the institute’s Academic Outreach and New Initiatives Office . Manasvi is not merely an educational engagement; it is a transformative platform aimed at inspiring and empowering young girls to pursue careers in STEM, fields traditionally dominated by men. At the heart of Manasvi lies the ambition to address the deep-rooted gender disparity in STEM education and careers . Despite producing the largest number of science graduates globally, India continues to see disproportionately low female representation in STEM careers —a statistic that underscores the urgent need for su...
