Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster.

This ultimate speed limit is a curious fact and one that runs quite against our common intuition. After all, if you are zooming along in your car and step on the gas, you’ll go faster. And while your car has a top speed, we know of faster things like fighter jets and bullets. However, speeding up eventually stops working. No matter how hard you try...
To understand the real reason why you cannot go faster than light requires that we learn a key idea from Einstein’s theory. While our common experience tells us that space and time are different things, he realized that they are more similar than different. Instead of space and time, there is a single thing, called spacetime. This idea is perhaps m...
The reason that it is hard to travel through space at the speed of light is that you must push the object out of moving in the time direction to moving more in the space direction. And that turns out to be difficult. But, even if you are successful, you can’t beat that single speed. So, that’s it. The real reason you cannot travel through space fas...
Apr 25, 2022 · So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note ...

Mar 19, 2018 · Similarly, when electrons travel through water at speeds faster than light speed in water, they generate a shock wave of light that sometimes shines as blue light, but can also shine in ultraviolet. While these particles are traveling faster than light does in water, they're not actually breaking the cosmic speed limit of 299,792 kilometres per second (186,282 miles per second).
Apr 23, 2021 · If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction.

Jan 23, 2024 · Can you go faster than light speed? Nope. Nothing can. Any particle with zero mass must travel at light speed. But anything with mass (which is most of the universe) cannot. The problem is relativity.
