Under what conditions can an object move faster than light?

I'm not suggesting the Einstein was wrong. I don't just mean the speed of light in a vacuum. I don't mean apparent speed at non-cosmological distances. Please include light illusions due to movement angles. Give examples.Under what conditions can an object move faster than light?

Spent nuclear fuel exhibits Cherenkov radiation - where beta particles are emitted by radioactive decay - they are moving faster than the speed of light in water at that point, and emit a blue-violet light to slow down. It is very possible for an object to move faster than light - objects at the end of the observable universe are doing so because the very fabric of space-time is expanding faster than light - at roughly 14B light years away. Einstein's equations don't preclude an object traveling faster than light speed, just it takes an infinite amount of energy to accelerate mass to light speed - (in a vacuum of course) - the energy for an object to travel much faster than C is less than infinite...
There's nothing impossible about travelling at greater than the speed of light in a medium. Cosmic rays in air and neutrinos in the interstellar medium do it all the time. What cannot occur is motion faster than c, where by convention we call c the ';speed of light,'; because light in vacuum was the first thing observed to travel at that speed. Kind of an unfortunate name, actually.
Well as far as we can tell none...at least not naturally however in recent years a molecule i belive called attackion was discovered and forgive me if I am wrong but i believe that it can travel at ANY speed thanks to some sort of field around it so long it does not go any SLOWER than the speed of light.
Light only travels at the speed of light in a vacuum. In another medium, it moves slower. That's what caused the Chrenkov effect - neutrinos moving faster than light in a medium. We've slowed light down in the lab to the point where you could run faster than it.
well, there arent that many. there are loopholes in einsteins theories like the way wormholes are allowed to exist. but theree is a theoretical particle in the universe that is called a tachyon which is constantly traveling at any speed faster than light.
If you looked through a straw and pivoted it at the center at some distance it would be passing through space faster than the speed of light,this would be an illusion.


Nothing can exceed the speed of light.
in reality, none. It is impossible. But in math, through a wormhole. That is it.
