Somehow, we all know how a warp drive works. You're in your spaceship and you need to get to another star. So you press a ...

Special relativity tells us motion warps space and time. Einstein’s central coup with general relativity was to combine that with a principle noted over three centuries earlier by Galileo ...

General relativity "describes how our universe ... But Einstein was not satisfied. Special relativity was just that—special. It could not describe all types of motion, such as objects in the ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

His theory of special relativity stemmed from his desire ... In 1908, before Einstein published his work on general relativity, mathematician Hermann Minkowski introduced the concept of four ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

Albert Einstein had described the special theory of relativity in ... he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed ...

The special theory of relatively left Einstein with many questions still unanswered. He didn't let them go, however, and in answering them he developed the general theory of relativity ten years ...

A new understanding of how an observer can change the disorder, or entropy, of a quantum object could help us probe how ...

Ten years before general relativity, Einstein came up with special relativity, which explained the relationship between space and time – and how they are related to each other. 'Special' means ...

Here are a few thought experiments that demonstrate some of Einstein's most groundbreaking discoveries, including his special and general theories of relativity. What would happen if you chased a ...

In 1994, Miguel Alcubierre was able to construct a valid solution to the equations of general relativity that enable a warp drive. But now we need to tackle the rest of relativity: How do we ...
