  1. First off, I'm a COMPLETE amateur. I am just an average Joe who has a lot of interest in Cosmology and I randomly googled the comparison of galaxies to hurricanes and it took me to this forum. Signed up to ask these questions. In the most simple terms without going super into depth, do you think "scale" gets under appreciated a bit when it comes to comparing these two things? What if what "seems" enormous to us is actually small from the outside looking in? I saw comments about the comparison of rotation speeds between the two,, but say you were able to stand outside of our universe and look at it in a perspective to where a galaxy was scaled to the size of a hurricane.. How fast would galaxies be perceived to be moving then? Would it change? Basically, would "perception" of time be any different? 2nd question. Hurricane eyes follow the greatest source of energy (heat) and need that external source of energy to stay alive. What if galaxies don't need an external energy source to follow because the billions to trillions of stars inside of them collectively gives them all the energy they need to be self-sustaining? 3rd and last question. So it's theorized that black holes (if they indeed exist) are formed from collapsing stars. Well galactic centers have the biggest black holes (because theory says they have a lot more to eat). Is it even possible that after the Big Bang, there were at first not galaxies but singular, GINOURMOUS stars, on a scale we just don't see today (I mean WAYYY bigger than the biggest ones we observe now) and when they went supernova, a giant black hole was created (like the ones we see at the center of galaxies) and all the gas, dust, and elements created from the enormous explosion formed a cloud around the giant black hole that slowly organized around it, forming the galaxies with billions to trillions of little stars inside of them we see today? The first question I have off of that is "why wouldn't new ginourmous stars form again in the dust cloud if they were able to form earlier on?", but maybe inside of a forming galaxy, there are factors/conditions that prevent that from being able to happen again and the environment only allows for a bunch of smaller stars to be formed instead. I'm sure these questions are probably idiotic due to scientifically proven facts that I'm not aware of but this is just stuff that randomly pops up in my uneducated head.
