Is it possible to go from one galaxy to another?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

Are any distant galaxies moving towards Earth?

Messier 90 is part of the Virgo Cluster, a group of more than 1,200 galaxies. So, from the perspective of Earth, we see the galaxy moving toward us, even though other galaxies in the same cluster appear to be moving away from us at high velocities.

How long would it take to travel to another galaxy?

The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.

Is there a galaxy coming towards us?

The Andromeda Galaxy (M31) is indeed approaching us, by about 300 kilometers (190 miles) per second measured with respect to the Sun. The two galaxies will merge a few billion years from now. This is normal. Neighboring galaxies are bound into clusters by their mutual gravitational attraction.

Is it possible to travel to a neighboring galaxy?

For example, different satellites are orbiting around planets like Neptune but no man has ever gone that far in the space. Science did discover that there are hundreds and thousands of other galaxies in the universe other than the Milky Way. Since that moment, an idea has circulated the scientific world which is to travel to a neighboring galaxy.

Why is the distance to other galaxies so uncertain?

All of our measurements of distant galaxies depend upon the distance to the LMC, which is used as a stepping-stone. So, if our distance to the LMC is uncertain by 10\%, then every single distance to another galaxy will be uncertain by at least 10\%.

How can we tell how far away a galaxy is?

For very nearby galaxies, like Andromeda, this works pretty well. The amount by which we need to shift the other galaxy’s globular cluster histogram in brightness to make it match our Milky Way’s tells us how far away it is (relative to the Milky Way). But for really distant galaxies, we can only see the very bright globular clusters:

How long does it take to travel to another galaxy?

This shortens the time needed to travel to another galaxy with respect to the traveler. This phenomenon gives hope to the scientists that intergalactic travel is possible for humans. A common example that is quoted in this regard is that Andromeda Galaxy is 2 million light years away but it would take just 28 years for the astronaut.
