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 galaxy redshifted?
Galaxy redshift is much light the Doppler effect. If a galaxy is traveling away from us, the light that it emits and is seen by us is stretched out (the faster we are separating, the stronger the redshift), that means that the wavelegnth is stretched a bit, shifting the light towards red.
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 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)
Why is the light from Andromeda that reaches Earth 2.5 million years old?
The Andromeda galaxy is 2.5 million light years away, meaning that it takes 2.5 millions years to get here traveling at the speed of light.
When you see a galaxy 8 billion light-years away you are looking how many years into the past?
When you see a galaxy that is 8 billion light years away, the light that's dribbling into your eye left that galaxy 8 billion years ago, and has been traveling toward you ever since then. If you just happen to see the galaxy explode or turn blue while you're watching it, you'll know that it actually exploded or turned blue 8 billion years ago. Similarly, if the galaxy explodes or turns green tonight, you won't know about that for another 8 billion years from tonight.
How many years would it take a spacecraft in travelling at the speed of light to cross your galaxy?
a long time
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.

How long does it take light to cross the diameter of your Milky Way Galaxy?
About 100,000 years
How long does it take to travel from one galixy to another?
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.
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 far away is earth from the Andromeda galaxy in kilometers in scientific notation?
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
Why is the light from Andromeda that reaches Earth 2.5 million years old?
The Andromeda galaxy is 2.5 million light years away, meaning that it takes 2.5 millions years to get here traveling at the speed of light.
Would lights turn on in a faster than light spacecraft?
In theory time inside the vehicle would go on as usual, the occupants would notice no difference. The vehicle is traveling at super light speed and so is the light on board, anything not attached to the craft would be affected.
What galaxy is 60 light years away?
There is no such galaxy, the nearest galaxy is over 2 million light-years away.
