James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus
A striking new image from the James Webb Space Telescope reveals an Einstein ring in the Hydrus constellation. The phenomenon occurs when a massive foreground galaxy bends light from a hidden background galaxy, forming a near-perfect ring. This effect, predicted by Einstein’s theory of general relativity, helps astronomers study galaxies from the...

New Black Hole Theory Challenges Singularity: What You Need to Know
A new study has put forward a black hole model that eliminates the central singularity, a concept that has long troubled physicists. Researchers suggest modifying Einstein’s field equations to prevent mathematical values from reaching infinity at a black hole’s core. This approach could reshape our understanding of gravity, black holes, and eve...

Black Hole Singularities May Not Exist, Say Scientists
A new study questions the existence of black hole singularities, suggesting refinements to Einstein’s equations using quantum gravity concepts. Researchers argue that infinite density points may not be real, replacing them with highly curved but finite regions of space-time. While direct observation remains difficult, gravitational waves and earl...

Meta’s Reality Labs Unit Posts $5 Billion in Losses in Q4 2024
Reality Labs logged a loss of $4.97 billion (roughly Rs. 43,040 crore) in Q4, 2024. In an attempt to explain losses for Reality Labs, Meta CEO Mark Zuckerberg said, “generative AI, Reality Labs generally are more technical organisations which means higher cost and space being relative for their business functions.”

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

"Have To Compete, Co-Exist, Confront, Contest With China": Army Chief
Highlighting the complex nature of dealing with tensions with China, Indian Army Chief General Upendra Dwivedi said that India must compete, cooperate, coexist, confront, and contest with China.

New Research Could Resolve Stephen Hawking's Black Hole Radiation Paradox
Recent research indicates that black holes may actually be “frozen stars,” complex quantum objects that lack the typical singularities and event horizons of conventional black holes. This theory, led by physicist Ramy Brustein from Ben-Gurion University, aims to resolve Stephen Hawking's famous radiation paradox, which suggests information is l...

Opinion: A Simple Majority Is Very Much In BJP's Reach. Here Are The Numbers
There are a few methods through which parties distinguish strong seats from the weak. Data show that the BJP, in comparison to the Congress, has a higher number of strong and relatively strong seats and much fewer difficult or weak seats.

Scientists Test Einstein's Relativity On A Cosmological Scale And Discover Something Strange
Researchers will be able to use these statistical methods to continue tweaking general relativity, explore the limits of modifications, and pave the way to resolving some of the open challenges in cosmology.

Gravity Has Remained the Same for the Entire Age of the Universe: Study
A new study suggests that the nature of gravity has remained constant for the entire history of the universe. To make things clearer, researchers from the Dark Energy Survey (DES) Collaboration have used the Cerro Telolo Inter-American Observatory's Victor M. Blanco 4-metre telescope in Chile and observed galaxies up to 5 billion light-years away.
