When people say “nothing can travel faster than the speed of light, information cannot travel faster than the speed of light”
What do we mean by information? and there can be non-information? how it would like?
In: Physics
According to our current understanding of physics, there are several [elementary particles](https://en.wikipedia.org/wiki/Elementary_particle), and four [fundamental forces](https://en.wikipedia.org/wiki/Fundamental_interaction) that cause these particles to interact.
So, “information” from a physics point of view is the “force” or “forces” caused by one particle being felt by other particles. As an example, all the material in the Sun creates gravity, and electromagnetic radiation (light), and that’s how we know the Sun is there. The Earth “feels” the gravity and light too. The strong and weak nuclear forces don’t have the range to be “felt” by the Earth.
So “information can’t travel faster than the speed of light” means that the effects of any particle cannot be felt (at distance) faster than the speed of light. No matter which force they’re creating, gravity, electromagnetism, nuclear, or any other forces that maybe we haven’t discovered yet, who knows, none of these forces can propagate out from that particle that creates them, faster than the speed of light.
