How do the movement of a particle relate to the speed of light
what is it that prevents it to travel faster than c?davec426913 said:special relavitiy does not specifically state that nothing can travel faster than the speed of light. Sr does state that nothing can start off at slower than c and reach or exceed c.
Hypothetical particles called tachyons travel faster than c. They cannot slow down to or below c. They are forever cut off from interaction with our sub-c universe.
To summarize Fredrik's post:DRMOKADI said:what is it that prevents it to travel faster than c?

That also implies to me, that a photon of light never experiences time, distance of space it simply starts to exist and in zero (it's own time) time ceases to exist.
Yes, according to the theory of relativity, nothing can travel faster than the speed of light in vacuum, which is approximately 299,792,458 meters per second. This means that no matter how much energy an object has, it cannot exceed the speed of light.
This is because as an object approaches the speed of light, its mass increases exponentially, making it more and more difficult to accelerate. At the speed of light, an object would have infinite mass, making it impossible to accelerate any further.
In theory, only massless particles, such as photons, can travel at the speed of light. They have no rest mass, so they are not subject to the same limitations as objects with mass. However, even these particles can only travel at the speed of light in a vacuum, as any interaction with matter would slow them down.
There are some phenomena, such as the expansion of the universe, that may appear to exceed the speed of light. However, this is due to the stretching of space itself, rather than an object actually traveling faster than light. Additionally, some theories propose the existence of particles called tachyons, which would travel faster than light, but they have not been observed or proven to exist.
At the moment, there is no known way to travel faster than light. Some theories, such as wormholes or warp drive, propose ways to bend or manipulate space-time in order to travel faster than light. However, these are currently only theoretical and have not been proven or successfully implemented.
