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.

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

"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 ...

Scientists believe that spacetime may have emerged, in part, from a quantum property called “magic.” “Magic” describes how hard a quantum state is to simulate on a regular computer. According to a ...

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 ...

Here’s what you’ll learn when you read this story: Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their ...
