No-one can go that fast. Yet...
No. Yeager has travelled faster than sound, but no one has travelled faster than light yet
Then our Universe would be quite different than it is.
No plane is faster than light.
Nothing travels faster than light.
Recent experiments at CERN suggest that neutrinos travel faster than light, but this experiment has not been replicated anywhere else and needs significant backing before it is to be accepted as a phenomenon.
we would be all screwed
Hasn't taken place yet, and will probably never happen.
the thing which is faster than light is neutrinos which is 25parts per million faster than speed of the light, its scientifically proved.
No, gravity is not faster than light. According to the theory of relativity, nothing can travel faster than the speed of light in a vacuum.
Hasn't been one yet.
Nobody knows for sure. We have never witnessed a physical object traveling faster than the speed of light.
No. Exactly what would happen if someone were to travel faster than light, science don't know - which makes sense as science isn't really sure how one would go about travelling faster than light to start with. But of all the possible strange things that might occur, changing something that has already happened - making someone unborn - is really, really unlikely.
