This year, Einstein's theory turns 100 years old. To celebrate that milestone, a local astrophysicist is taking it upon himself to make relativity easier for all of us to understand.

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

His theory of general relativity says that gravity is a natural consequence of a mass’ existence in space – that mass can bend space and time.

Albert Einstein rose to fame in 1905 after his theory of relativity transformed our understanding of space and time. Einstein was the first to confirm that "no object could travel faster than the ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

A team of scientists claims a computational tool for studying black hole collisions could be our best bet for answering ...

The answer goes back to the old faithful theory of financial relativity. What this person is neglecting to point out is that their friends were a police officer and a schoolteacher for 25 years.
