For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum theory—our two best bets on understanding the universe on a macroscopic and ...

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

Albert Einstein’s general theory of relativity does a great job at explaining gravity but it is thought to be incomplete ...

In search of a united scientific theory, a new quantum gravity paper might have proposed an interesting aspect that made the ...

We can't see dark matter directly, so studying it pushes the boundaries of our creativity as scientists. How exciting, says ...

Why do we call the people in our families relatives? It is because they exist relative to us and us to them. Most of the time we see ourselves as the star in our own stories and others as planets ...

In 1999, Belgian physicist Chris Van Den Broeck implemented a minor alteration to Alcubierre’s concept by shrinking the ...
