Objectively, about 26,000 years - but IF (and you cannot!) you could travel at the speed of light, it would seem like no time at all had passed.
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.
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.
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.
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.
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.
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.
25,000 years.
a long time
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
The Canis Major Dwarf Galaxy is currently considered to be the closest galaxy to the Milky Way. It is 25,000 light years from our solar system and 42,000 light years from the center of the Milky Way. Its status as a galaxy is still disputed in some scientific circles. If the Canis Major Dwarf Galaxy loses its galaxy status, then the Sagittarius Dwarf Spheroidal Galaxy would reacquire the title as the Milky Way's closest neighbor. It is it is roughly 50,000 light years from the center of the Milky Way.
About 100,000 years. (the diameter of the Milky Way galaxy is 100,000 light years)
Very long. Use the formula: distance = time x speed; solving for time: time = distance / speed. The center of the galaxy is estimated to be at a distance of about 27,000 light-years; this is about 1.59 x 1017 miles. If you divide that by 50,000 miles per hour, you get 3,180,000,000,000 hours, or 132,500,000,000 days, or 363 million years.
