About 100,000 years.
it would take you approximately 100,000 years to travel across the milky way. happy traveling :-) !
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
At the speed of light, it takes millions of years. For example, the Andromeda galaxy, which is the closest galaxy to our Milky Way galaxy, is about 2.5 million light years away, that is, traveling at light speed it would take 2.5 million years to get there.
When the light is traveling through vacuum.
The speed of light depends mainly on what light is traveling through. The speed of light in a vacuum is 300,000 kilometers per second. The speed of light in other substances can be a little slower, and sometimes a lot slower.
Electrons are able to travel close to speed of light.
At the speed of light: About 100,000 years.
Yes.
It depends entirely on what speed you are travelling at. Traveling at the speed of light(299,792,458 m/s) it would take 9.131 days to travel to the nearest galaxy to earth other than the milky way, Canis Major Dwarf http://en.wikipedia.org/wiki/List_of_nearest_galaxies
To an outside observer a person traveling at the speed of light would be frozen in time. To the person traveling at the speed of light, things would seem normal.
ANY light traveling through the same medium (stuff) has the same speed.
