    Humans have not achieved intergalactic space travel.

    Intergalactic means "between galaxies", and we haven't even achieved interstellar travel yet (4 craft are on the edge of our solar system, but not really interstellar yet).

    In movies and books, intergalactic travel is usually achieved through either warp (faster than light) drive or wormholes. Neither are scientifically possible (as far as we know).

    In Science Fiction Books and Movies they have faster than light capability or they have worm holes like in the TV series Star Gate.

    In the REAL world we can't even send a man to Mars let alone intergalactic.

    In science its said nothing is impossible,but travelling to the nearest galaxy is second last to impossible.Andromeda,the nearest galaxy to the milky way is around 10 raised to 19 kms away.Even if someone travels several times to speed of light,still it would take millions of years to reach there.Unless and until there is some kind of shortcut or say a "wormhole" in space,its not possible.

    It isn't.

    "Intergalactic" means "between galaxies". The closest other galaxies are many thousands of light-years away. With our current technology it would take millions or billions of years to reach them.

    Wormholes, that are achieved by bending space and time. But that is only a theory. Also, such things would need huge amounts of energy; our planet will not even have that much energy.

    Imagination is still the only thing faster than light.
