We know that the answwer must be "No", simply because
we know that NOTHING is faster than the speed of light.
8600000000mph
No. An A.U. is the average radius of the Earths orbit around the Sun. (which can be measured in light years or light minutes (about 8) if you want).
Light.
The speed of knowledge/information travels faster than the speed of light.
The closer planets are to the Sun the faster their orbit speed
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
Light is faster because speed does not move. Speed is a measure of the rate of movement but, in itself, it does not move - at all!
Nothing travels faster then the speed of light (according to our understanding of physics)
* The speed of light in a vacuum, * The speed of sound,
No, not quite. We know that for sure, because nothingmoves faster than the speed of light.
Faster then speed of light.
Yes.
