Why is a light year a unit of distance rather than time?
A light year is a distance measurement because it would take something a year travelling at the speed of light to cross. It is called a light year because it helps astrologers/scientists understand the vastness of the distance between two things; for example, Our Galaxy (The Milky Way Galaxy) and our nearest Galaxy (Andromeda Galaxy)
How many years would it take a spacecraft traveling at the speed of light to cross the milky way galaxy?
The very fastest human-made spacecraft ever aren't out of this solar system yet, and they were launched in the 70s."Billions of years" is, if anything, an understatement.
What is the maximum recession velocity of the galaxy observed?
Some of the furthest galaxies are believed to be "travelling" faster than the speed of light. They are not actually "travelling" faster than the speed of light, but creating space, faster than the speed of light.
Can you cross Galaxy?
Our galaxy has a diameter of about 100,000 light-years; at the speed of light, that would take 100,000 years. Currently there is no technology that allows us to do this.
Can you come out of a galaxy?
With current technology, that's not possible. At the speed of light, it would take you tens of thousands of years to leave our galaxy. The speed of light seems to be a speed limit in the Universe, and current technology is nowhere near travelling the speed of light.
How long does it take light to cross the diameter of your Milky Way Galaxy?
About 100,000 years
How large is the galaxy in which Star Wars is set and is it smaller than our galaxy?
i would have thought it was conciderably smaller because the space ships crosed it(at light speed) in minutes. if you tryed to cross our galaxy at light speed it would take billions of years.
How long would it take to cross the milkyway at an impossible speed of light?
About 100,000 years. (the diameter of the Milky Way galaxy is 100,000 light years)
When was Travelling Like the Light created?
Travelling Like the Light was created on 2009-07-13.
Where is the next galaxy?
The nearest large Galaxy is the Andromeda Galaxy or M31 (also Great Andromeda Nebula in old texts)It is a spiral galaxy, located about 2.5 million years from us.Unlike most galaxies, the Andromeda Galaxy is getting nearer to us and will eventually in a few billion years time "merge" with the Milky Way.See related link for more information
Will you move into another galaxy?
Not in the near future. Other galaxies are hundreds of thousands, or millions, of light-years away; travelling at the speed of light, it would thus take millions of years to travel to most galaxies; travelling at a lower speed would, of course, take longer.Not in the near future.

Would Black Holes be accessible for vehicles travelling at near light speed?
I'm not even sure what this is supposed to mean. "Accessible" how?You can go into a black hole. You don't need "a vehicle travelling at near light speed" to do so (of course, if you're on Earth now and want to get to a black hole before you die, such a vehicle would probably be required, since all the ones we know about are at least tens of thousands of years away at any speed any Earth-built spacecraft has ever reached).You can't come out again. Period. Not in a vehicle travelling at "near light speed", not in a vehicle travelling AT light speed. The escape velocity for a black hole exceeds the speed of light in a vacuum.
