I'm assuming Google is correct on these:
Our galaxy, the Milky Way, is estimated to contain between 100 and 400 Billion stars and is 100k light years across. So, traveling at the speed of light, it would take you 100k years to cross our galaxy.
The closest galaxy to ours, Andromeda, is 2.5 Million light years away and may contain as many as 1 Trillion stars. So the light from Andromda thst astronomers can see with extremely powerful telescopes originated approximately 2.5 million years ago.
And there is no way Andromeda is the only other galaxy in the universe, imo.
I cannot fathom how enormous the universe actually is. Nor can I believe that our little bundle of humanity is the only intelligent life in the galaxy, much less the universe. And, as much as I like Star Trek and Star Wars, traveling at warp speed (the speed of light) wouldn't allow humans to explore but a very small portion of the Milky Way, much less anything else.
