Only 300k? A miniscule nunber.

There goes property values. My old galaxy is worth less and less. Might need to invest in a galactic cluster while they are cheap.

I don't think its a matter of it getting bigger. We are slowly being able to see further and further with the improvements of better and stronger telescopes. We are discovering more unseen areas from "the planet "Earths'"" perspective! We (humans) are not even a drop in the universal bucket. I think that we are more like an atom on the universal stage!

How did the universe get bigger? We simply became aware of more of it. It would be next to impossible to map the universe but we can map areas closest to us.

i'm no expert but would this be a clue of the actual direction of the big bang?

Before they find the end of the universe, it is a bit nonsensical to regard the Big Bang as anything but a scam, especially since there are other explanations for the redshift and the MWBR, and since no dark matter has ever been seen.

Sounds like the universe just got a tiny bit bigger considering there are an estimated 10 billion galaxies.

So much to explore
