Every time I see these "Zoom into.." vids, it really quickly reminds me of how small we are (earth, or our galaxy for that matter), and how incredibly vast and expansive the rest of our Universe actually is. It's hard to even grasp just how big it really is. The first time I saw the Hubble Deep Field, and then the ultra/eXtreme Deep Field shots , I was just amazed. the Hubble was pointed into a one TINY point in space, like the tip of a needle in the night sky, equal to 1/13,000,000th of the total area of the sky.. and in this TINY spec of space revealed 5000+ different objects. Most of which are galaxies. galaxies..
Hard to even think about when you consider what's else is in the rest of the area they didn't point the Hubble.
This also makes me believe that we are definitely not alone in this universe. With that many Galaxies in one small spec of the universe, let alone the rest of it, hard not to think we could be alone. Scientists/Astronomers first estimate said there are at least 100-200 Billion galaxies in the Universe, with recent estimates put it above 2 Trillion galaxies. It's said our galaxy, the Milky Way, is said to have 100 Billion stars on the low-end, and possibly upwards of 400 billion on the high-end. Taking it further, it's estimated there are 100 billion planets in our Milky Way galaxy. Of those 100 billion planets, it's estimated there may be 8.8 billion of those would contain "earth-size" planets.. Kinda making it a given, in my opinion, that out of that vast number alone, there would have to be life out there somewhere.. Let alone the trillions of other galaxies. lol..
Anywho.. just something to think about next time your doing some star gazing.
