You,ve got some serious problems. According to the math, your length is negative
and imaginary, your mass is negative and imaginary, and although your own wrist
watch is acting completely normal, everyone else's clock is moving at a negative
imaginary rate ... whatever that means.
Travelling faster than the speed of sound causes a loud noise called the sonic boom.
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
supersonics
Some of the furthest galaxies are believed to be "travelling" faster than the speed of light. They are not actually "travelling" faster than the speed of light, but creating space, faster than the speed of light.
Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity. Looking at the situation from the other side, if it were possible to travel faster than light, then from some point of view, you would be travelling backwards in time. For more details, read about the definition of "simultaneity" in the Special Theory of Relativity.Probably none of the two is possible - travelling backwards in time, and travelling faster than light.Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity.

That is a good observation indeed. This happens probably because your hands have better blood supply than your feet.
Boats, horses, carriages, feet. That was about it. Travelling by boat was much faster than travelling overland.
it faster than sound
The motorbike was travelling faster and overtook the car.
If both balls are travelling at 30m/s, then they have identical speeds, and neither is travelling faster.
For when he's tired... Also if he is travelling with company he can't expect his travelling partner to run as fast as him.
This has not happened yet. It is usually believed that travelling faster than the speed of light is not possible.
