A new study just added an interesting twist to the complicated history of the physics theory.

What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

In 2015, the general theory of relativity will be 100 years old. In November 2015, Albert Einstein gave weekly lectures to the Prussian Academy of Sciences in which he set out the fundamental field ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

One of the goals of modern physics is to determine the underlying rules that govern our reality. Indeed, one of the wonders of the universe is that just a few rules seem to describe many aspects of ...

Pedro Ferreira looks back at how Einstein himself and a panoply of other physicists have framed the theory. Until very recently, relativists were few and often self-taught. General relativity still ...

Cormac O’Raifeartaigh reviews The Perfect Theory: a Century of Geniuses and the Battle Over General Relativity by Pedro G Ferreira Fighting it out: an artist's impression of two black holes circling ...

Since 2007, physicist Leonard Susskind has regularly delivered a lecture series called the Theoretical Minimum, on the foundations needed to study different areas of ...
