We spoke with theoretical physicist Brian Greene about Einstein's theory of space-time. Many scientists believe space-time is a fundamental concept. But Greene thinks there might be something ...

NASA was formed in 1958 "to provide for research into problems of flight within and outside the Earth's atmosphere, and for ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

Physicists have created a 3D shape called the cosmohedron, which can be used to reconstruct the quantum wavefunction of the universe – and potentially do away with the idea of space-time as the underl ...

The theory is a series of equations defined by Einstein. These equations combine space and time to create space-time. Gravity is explained by these equations, which are consistent with what we see ...

According to Einstein's theory, the universe is deformed by ... In our study, we used this data to directly measure the distortion of time and space, enabling us to compare our findings with ...

The Big Bang Theory explains how ... A telescope is almost like a time machine, allowing us to peer back into the distant past. With the aid of the Hubble space telescope, NASA has shown us ...

A rare Einstein ring spotted near our galaxy offers a unique chance to test Einstein’s general relativity and study the ...
