How long would it take to get to Andromeda Galaxy at the speed of light?

Light would reach it in 2.2 million years, but according to Einstein's relativity, a spaceship can only get close to the speed of light , but never reach it. At that sort of speed, due to time dilation , a spaceship would get there almost instantly, but it would take an almost infinite amount of energy.
So a spaceship very very close to the speed of light could reach it in minutes, whereas on Earth 2.2 million years would have passed.
Not only does time slow down, but mass increases and length contracts at relativistic velocities. So as an object approaches the speed of light, its mass becomes greater and greater, until eventually it begins pushing up towards the mass of a star. The amount of energy needed to push the mass higher becomes correspondingly greater. Another effect, however, is that as you approach the speed of light, your own escape velocity increases. Before you reach the speed of light you enter your own Schwarzchild radius, effectively pinching off from the rest of the universe as a black hole. So you can't even theoretically get "infinitely close" to the speed of light. There are limiting factors precluding it.

Does the speed of light allow the Andromeda Galaxy to emit a blue shift?
There is some blueshift in the Andromeda galaxy as it is moving toward us. The speed of the Andromeda Galaxy relative to the sun is about 300 kilometers per second or about 0.1% the speed of light. The blueshift would be detectable by instruments but not to the human eye.
How long to travel to Andromeda galaxy?
The Andromeda Galaxy is about 2.5 million light years away. How long it would take to get their depends on how fast you go, but at the speed of light it would take 2.5 millions 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 long would it take you to travel to the Andromeda galaxy at an average speed of 20mph?
The Andromeda galaxy is around 2.5 million light years away, but is moving towards out galaxy at a speed of about 100 to 140 kilometres per second (62 to 87 miles/sec). Our galaxy will collide with it in around 4.5 billion years. A long time, but you wont get far travelling at 20mph in that time, on an astronomical scale anyway, barely outside our own solar system.
How far from the Milky Way Galaxy would the Andromeda Galaxy be on this scale?
No scale was specified. However, if the Earth was one inch, the Andromeda Galaxy would be 29,300,000,000 miles away.

Can you send astronauts to another galaxy?
You could send them in the right direction but they would never make it. Even if they traveled at the speed of light, it would take 2.2 million years to get to the nearest galaxy - The Andromeda Galaxy
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
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 far from the Milky Way Galaxy would the Andromeda Galaxy be if the Milky Way was 1cm?
About 25.4 cm. The Andromeda Galaxy is about 2.54 million light years from us. The Milky Way is about 100,000 light years across. So if 100,000 lights years equals 1 cm, then 2,540,000 / 100,000 = 25.4
Are there any probes in the Andromeda Galaxy?
No human probes, no. The Andromeda Galaxy is simply too far away. It is about 2.5 million light years away, meaning that even at the speed of light it would take 2.5 million years to reach it, and no manmade probe can travel anywhere near that fast. Currently the furthest man-made probe is about 16 light ours from Earth, and it took nearly 35 years to get that far. Though technically we have no way of knowing if there is intelligent life somehwere in the Andromeda Galaxy that might be exploring their own solar system with probes.
How long will it take to get to Andromeda galaxy by going 360 000 000 000 000 000 000 Kmph?
You can't go that fast. That would be faster than the speed of light. Anyway, for a hypothetical calculation, divide the distance by the speed.
Are there any people who have been to the Andromeda Galaxy from Earth?
Not as far as anyone knows, and it's really very unlikely. Traveling at the speed of light ... which is impossible for people ... it would take millions of years ... which is longer than people have existed ... to reach the Andromeda Galaxy. So it's probably a safe bet that earth people have never been there.
