Though there is an overwhelming amount of information floating around out there about the theory of relativity in all her guises, I was stumped last week when my eight year old nephew asked me to ...

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 ...

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 ...

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 ...

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 ...

General relativity is a profoundly complex mathematical theory, but its description of black holes is amazingly simple. A stable black hole can be described by just three properties: its mass, its ...

Over the weekend, for some odd reason (probably LIGO-related), political blogger Kevin Drum decided to take on General Relativity arguing that despite its intimidating reputation, it's not that ...

In 1905, at the age of 26, Albert Einstein proposed his special theory of relativity. The theory reconciled the physics of moving bodies developed by Galileo Galilei and Newton with the laws of ...

In 1907, Albert Einstein had his “happiest thought” — people in free fall do not feel their own weight. This simple idea laid the foundation for his general theory of relativity, which Einstein ...

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.

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 ...
