Galaxy clusters, the largest structures held together by gravity in the universe, may be far heavier than scientists once ...

A new gravitational model suggests dark matter may not exist. By allowing gravity to weaken more slowly at large distances, physicist Naman Kumar shows galaxy rotation curves can be explained using ...

"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot explain. The dominant answer has been dark matter, an unseen substance ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

As boarded‑up units spread from coastal towns to former industrial centres, a new ​Guardian investigation reveals how ​o​ur high streets have become a litmus test for public frustration and ​p​olitica ...

Guwahati: A study by the department of physics at Tezpur University (TU) reported new findings on how gravity works inside the Sun where the key mechanism of energy production is thermonuclear ...

The research, conducted by the Department of Physics at Tezpur University (TU), has been accepted for publication in Physical Review E, a leading journal of the American Physical Society Guwahati: A ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

• Our approach is to look for a hidden acceleration a using an equation that adds to the expected velocity, and is predictable for any galaxy that has sufficient stellar velocity data. There is no ...
