Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...

Every generation grows up with starships that jump across galaxies in a heartbeat, but the real universe is far less forgiving than the screen. The same physics that lets GPS satellites work and ...

Humans are one (small) step closer to traveling at faster-than-light speeds.

A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not very little time. None. That result is not a loose approximation or a poetic ...

The universe has a speed limit, and it's the speed of light. Nothing can travel faster than light — not even our best spacecraft — according to the laws of physics. So, what is the speed of light?

In late 2020, physicist Harold “Sonny” White, PhD, research director of the nonprofit Limitless Space Institute, noticed something peculiar—and familiar—in a circular pattern of data plots generated ...

(via Sabine Hossenfelder) Recently, the James Webb Space Telescope observed signals that moved faster than the speed of light. Does this mean that faster-than-light travel is real? If not, what ...
