The new approach, called string theory, captured the attention of researchers worldwide, as its elegant mathematics offered the potential to reconcile the two most successful yet conflicting ...

Are black holes tunnels to other locations in spacetime? Are they wormholes connecting different regions of the universe? A study has provided a clear answer to this question. The remainder of this ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

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.

The evidence for the Big Bang is overwhelming, but we cannot describe what goes on in that event. We can’t accurately call it ...

A team of scientists has unveiled a bold new theory that seeks to unify the two pillars of modern physics—quantum mechanics and Einstein’s general relativity.

Because string theory’s predictions are vast and varied, the researchers instead asked if there’s a simple particle scenario that string theory just can’t accommodate.

Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently ...

Albert Einstein 's theory of general relativity —which explains gravity as the product of the distortion of space and time—may not be universally applicable.

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 ...
