From Alcubierre’s warp bubble to quantum scale experiments and gravitational wave signatures scientists are quietly building ...

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 ...

The idea of warp drive—the ability to travel faster than the speed of light—has fascinated humanity for decades. It began as a fictional concept in Star Trek and Star Wars, fueling imaginations and ...

The light echo around the star V838 Monocerotis as seen by the Hubble Space Telescope in November 2005. When I was a teenager, I was—shockingly, I know—deeply nerdy. At a science-fiction convention, I ...

(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 ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.
