Question

Intergalactic bypass

Answer 1

Answer:

Intergalactic travel is hypothetical crewed or uncrewed travel between galaxies. Due to the enormous distances between our own galaxy the Milky Way and even its closest neighbors-tens of thousands to millions of light-years-any such venture would be far more technologically demanding than even interstellar travel. intergalactic travel for humans is therefore possible, in theory from the point of view of the traveller Accelerating to speeds closer to the speed of light witha relativistic rocket would allow the on-ship travel time to be drastically lower, but would require very large amounts of energy

Intergalactic gas is so tenuous that it emits no light of its own. ... Instead astronomers study it indirectly by observing how it selectively absorbs the light coming from faraway sources known as quasars.
