Warp drives have long lived in the realm of science fiction, but the underlying physics that inspired them is very real and surprisingly precise. As researchers probe the edges of general relativity ...

Besides quantum mechanics, another interesting topic in physics is relativity. Let’s take a look at it! Of all the force fields, the gravitational field is the one man has known for the longest time.

Scientists, or at least their wild-haired fictional counterparts, promised us time travel and still have not delivered. Forget walking with dinosaurs or killing baby Hitler; I’d be happy just to warn ...

In the past, physicist Stephen Hawking has hosted a champagne party for time travelers with balloons and hors d’oeuvres.

Time travel has been a fantasy for at least 125 years. H.G. Wells penned his groundbreaking novel, The Time Machine, in 1895, and it’s something that physicists and philosophers have been writing ...

If general relativity, Einstein's theory of gravity and space-time, allows for the ability to go back in time and kill your grandfather, asks David Z. Albert, a physicist and philosopher at Columbia ...

One of the most mind-bending aspects of Albert Einstein's Theory of Relativity is time dilation. Time moves more slowly for a person in motion compared to a person at rest. This effect also applies in ...
