How long would it take to cross the milkyway?

Answer 1

From edge to edge (Although there is no real defining edge) at the speed of light, it would take approximately 100,000 years.

At 1,000 mph it would take you about 67,000,000,000 years. (67 billion years - about 5 times longer than the age of the Universe)

Answer 2

That will of course depend on the speed. With current technology, it isn't possible to travel there. The center of the Milky Way is at a distance of about 26,000 light-years; travelling at the speed of light, it would take 26,000 years to get there. Travelling at 1% of the speed of light, it would take 2.6 million years. Etc.

Answer 3

That will depend on the speed. At the speed of light, it should take about 26,000 years, since the center of the Milky Way is about 26,000 light-years away from us.

Answer 4

As you are already there, no time at all.
