Inside the bizarre bubble where physics lets speeds beat light
In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...
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 ...
Here is a thought experiment for you: imagine shining a powerful laser at the moon, the beam cutting through space until it lands on its dusty grey surface. Now flick the laser so the spot of light ...
An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel ...
(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 ...
CC0 Usage Conditions ApplyClick for more information. Imagining travel across the immense distances in outer space required envisioning fictional methods of faster-than-light-speed travel. Whether ...
