You have to be going faster than the speed of light. which is not really possible for us yet... but we will get there eventually!
Additional answer
Sorry, but pace ships don't travel anywhere the speed of light. Their speed varies but 25,000 mph is ballpark
1000000000000000000000000000000000000000000 fast
Approximately 18,000 mph.
17,500 mph.

These were the Apollo missions.
It depends on where in space they are but they often travel extremely fast, upwards of 11 km per second
space ships. some people think that wormholes can lead to other galaxies
50 mi. an hour
Fast enough to cause a big spolosion

Theoretical, infinate, if you travel through warp space.
Yes, you can travel through empty space. The Sun, Earth, moon, satellites, space ships, atoms, and subatomic particles all travel through empty space. Greater than 99.999% of matter is empty space.
