heard about particles move faster than light!
Tachyons - theoretical particles - are supposed to be FTL. Quantum entanglement happens FTL but there is no communication between 2 points here.
Phase velocity can exceed c. Group velocity can't. All matter is associated with group velocity. So, no matter can exceed c. What are phase and group velocities? Next semester.
I don't think these exist. Even though it is possible to postulate negative mass, negative time or some other condition that could make it possible. However for it to happen causality would need to be violated. i.e the consequences of an action would need to occur before the action itself happened. Not very likely.
Moving faster than light opposes einstien's law of cosmic speed limit it says nothing (a matter particle) can acquire the speed of light, though it can (may) travel with maximum 99% of the light speed...
No, thats a lie, light is the fastest thing in the universe, nothing can go faster that light. I heard that gamma rays travel at a speed similar to that of light. However, all electromagnetic waves (including visible light) travel at a speed of approximately 300,000,000 meters per second.
