The earth travels at 67,100 miles per hour and in an orbit around the sun. We don't hurdle through the universe because of the sun's gravity. If the sun were to suddenly disappear, we would not break orbit until 11 minutes after the sun disappeared. Nothing can travel faster than the speed of light. Not even gravity. So after the eleven minutes, then earth would hurtle away in a straight line and we'd be dead.

If the earth stopped moving, which isn't possible, time would probably speed up. I will try to explain why time slows down when you speed up:

Imagine a cylinder that has only a top and bottom, or if it makes it easier, a glass cylinder, but the glass can be penetrated. The cylinder has a mirror on either end and contains a particle of light bouncing up and down off the two mirrors. One bounce of the particle of light = one second. Now when you move the cylinder, the particle of light (assume the light can travel through the glass sides of the cylinder) has a further distance to travel to hit the other mirror. The faster you move the cylinder, the further the particle of light has to travel. If the light has to travel further, but remember it is still only one second per bounce off the mirror, the only way this can be explained is that time slows down as you travel faster.

So if time slows when you speed up, I suppose it is safe to assume that if we stop moving time would speed up to infinity.

However, I’m not really sure about that, and I doubt there is any way to prove it either way.
