There's really only like 2 trillion galaxies in the observable universe which isn't that much more than the number of neurons.

- asah 5y agoTIL there's about as many galaxies in the observable universe as trees in the planet. https://www.google.com/search?q=how+many+trees+are+on+earth https://www.google.com/search?q=how+many+trees+are+on+earth
- TaylorAlexander 5y agoYes but that’s just the observable universe. My understanding is that the observable universe is only a fraction of the total universe. However that was something I found hard to verify so I could be wrong.
