19 mar 2018 · When Albert Einstein first predicted that light travels the same speed everywhere in our Universe, he essentially stamped a speed limit on it: 299,792 kilometres per second (186,282 miles per second) - fast enough to circle the entire Earth eight times every second.

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.
24 lis 2021 · Tachyons are hypothetical particles that move faster than the speed of light and travel backward through time. Whether they exist is still up for debate.
9 lis 2010 · Quantum entanglement moves faster than light. If I have two electrons close together, they can vibrate in unison, according to the quantum theory. If I then separate them, an invisible...
25 kwi 2022 · Albert Einstein's theory of special relativity states that light travels so fast, in a vacuum, nothing in the universe is capable of moving faster. (Image credit: Yuichiro Chino via Getty...
22 wrz 2011 · An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light. Other researchers are cautious about the result, but if it stands...
27 wrz 2023 · All the known particles in the universe travel at or below the speed of light. However, the hypothetical tachyon particle could beat light speed.
