What is in the space between galaxies?
Could the barrier have a substance that repells normal mater.

There's an intergalactic medium. On average, it's hotter and even more rarefied than the interstellar medium inside galaxies, but it still fills all of space (and it does support sound waves of very low frequency).

Your best answer and all the rest are wrong. There is no space between galaxies. It is called spacetime - one word and one thing.

There's very little between galaxies - mostly elemental hydrogen.
No, there's no evidence of a barrier between galaxies.

The space between galaxies is pretty empty. There is some dust, gas, rocks, and maybe a star or two.
What barrier are you referring to?

From a handfull of light years to millions of light years. Much an empty void.
No such 'barrier' exists. Some long time in the future, Andromeda and Milky way will merge making a super galaxy.

Star Trek was *fiction*. There is no barrier at the edge of the galaxy.

it is a vacuum that perhaps contains some diffuse gas and dust, and perhaps some stars, asteroids and such. No fictitious "barriers" exist.
