Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

In this last part of our series on recently digitized books from the Wenner Collection, we are focusing on works that ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

Some random article came up on google for me about how there is a new attempt to reconcile both QM and Relativity through some space time dimension field. The point being that wouldn't such a theory ...
