Speed

the earth orbits the sun at 66,000 mph
The local group of galaxies are moving at about 1,300,000mph
but its 38 000 000 000 000 000 000 miles to the neighbour local group so itd take 3.3 billion years to get there

the Fastest Galaxy: 76,000 Miles per Second
thats 200 times faster than our galaxy
so itd take it 16 million years to travel the same distance at 76,000 mps, thats not a very long time in geology (the science about the ball we live on)

the speed of light is 670 million mph, so the fastest galaxy in the universe is travelling at half the speed of light (not sure where to exactly)
