"This discovery was partly serendipity! But, we believe there are many more such opportunities hidden in Hubble data." ...

What exactly is gravity, and how does it work? From Newton’s early groundbreaking discoveries to Einstein’s revolutionary ...

In 1919, a total solar eclipse allowed scientists to confirm Einstein’s theory of general relativity by observing how the sun’s gravity bent starlight. This discovery revolutionized physics and made ...

When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His gravitational model showed how Newtonian gravity, which had dominated ...

Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity.

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

It's almost as if gravity itself stops perfectly matching Einstein's theory." The cosmic glitch described by the team would require an alteration in a value called the gravitational constant.

Time, as we experience it on Earth, may not be as constant as we imagine. According to Einstein’s theory of general relativity, time is not uniform across the universe; it’s actually affected by both ...

Da Vinci's sketches, which were forgotten for decades, show triangles formed by sand-like particles pouring from a jar. These falling grains depicted experiments to show that gravity was a form of ...

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...
