To construct a warp drive, we'd need 10 times more negative energy than all of the positive energy in the universe. When you purchase through links on our site, we may earn an affiliate commission.

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

"The appearance of such structures sheds new light on the sorts of mathematical objects that nature is built from." Scientists have made the most accurate predictions yet of the elusive space-time ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

Theoretical computer scientists are always probing the relationship of space (memory) and time. For 50 years, experts knew that a calculation of X steps required X/log X memory slots, but a new study ...

In the moments before the Big Bang, our universe was a hot, dense, and extremely high-energy place. That all changed when the universe exploded 13.8 billion years ago. Rapid inflation divided a single ...
