BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

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

We all know that black holes are mysterious giants in the universe, with a mass beyond imagination and gravitational forces so strong that even light cannot escape. Our understanding of black holes ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed ...

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

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Albert Einstein is known for his haircut, theories of relativity and belief that “the fact that [the physical world] is comprehensible is a miracle.” What he meant was that via science, math and our ...

Hawking's second law of black hole mechanics, also known as Hawking's area theorem, states that the area of the event horizon ...

While the title makes this sound very science-based, this is still a financial planning article. Don’t worry if you haven’t heard of the theory of financial relativity, as it was made up while I was ...

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the Large Hadron Collider.
