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 ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights ...

Physicists have created a 3D shape called the cosmohedron, which can be used to reconstruct the quantum wavefunction of the ...

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

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 ...

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 ...

Scientists used the most massive fundamental particles to break special relativity, but even that didn’t work.

Space and time are "relative," flowing differently for each of us depending on our motion. Einstein's special theory of relativity, published a hundred years ago, also revealed that energy and ...

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 science that was repulsive to an idea of religious belief thus began to embrace religious ideas culminating with the ...

Could time itself actually explain our universe's expansion? Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the ...
