"In reality, space and time are strongly intertwined things and the union of them is called spacetime," explains Konstantin Batygin. The force that we understand as gravity, according to Batygin ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

Gravity can turn itself into light, but only if space-time behaves in ... forward and backward in time —Scientists create 'slits in time' in mind-bending physics experiment —10 discoveries ...

This spectacularly successful theory has correctly predicted phenomena from the bending of light ... that the geometry of space and time—spacetime—is determined by gravity.

Space might seem calm when gazing up at the night sky, but invisible waves ripple continuously through the universe, bending ...

On one side is the Einstein who in 1915 conceived general relativity, which describes gravity as the warping of space-time by matter and energy. That theory predicted that space-time could bend ...

But not gravity as we know it through the general theory of relativity, which says that space and time bend under the influence of matter and energy. Instead, he recasted Einstein’s famous ...

It was already a mind-bending shift, last century ... That would be demonstrated if general relativity is derivable from quantum gravity. But space-time and its behavior are very different from the ...

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically ...
