In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and acceleration. Initially ridiculed, Einstein developed key concepts after observing a ...

What if the Big Bang didn't begin with a singularity? This point of infinite density, which so divides physicists, could be ...

Why can't anything travel faster than the speed of light? Do black holes really suck? And why is the universe expanding? These are just a few of the questions author and astrophysicist Jeffrey Bennett ...

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 ...

A framework that relies on college-level mathematics could describe what happens to particles in so-called spacetime rips, gravity fluctuations such as those that occur during the birth of a black ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. When you purchase through links on our site, we may earn ...

Scientists may be celebrating the 100th anniversary of Albert Einstein’s general theory of relativity, but there was also a death in 1915. It was one of the many deaths of simple and intuitive physics ...

Astronomers have been searching for a mysterious substance called “dark matter” since the 1930s. Most scientists still believe it exists, despite many fruitless decades. Now we propose a new theory of ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. It's difficult to appreciate how revolutionary of a transformation it ...
