Well, do I have the facts correct.......... we are in the milky way galaxy, we can barely see the andromada galaxy, and there are 2.3 billion other galaxies? That we think are out there?
The other one is.........when our eyes see the light transmitted from the stars in the above mentioned galaxies the light was emitted some millions of years ago and those stars from which the light has been emitted have probably changed a great deal according to gaseous physics? Like maybe the stars don't really exist anymore, some do and some do not, depending on their age.
I guess I feel rather insignificant, it doesn't really matter who I sleep with or what I cooked for supper, it is really scary?
Despite all the question marks, you haven't really asked one. If you're asking whether your basic knowledge of the universe is correct then I have to say that you are almost wholly correct. Except for the bit about who you sleep with. Make the wrong choice here and your pitifully short existance could be a whole lot more difficult. It's all relative you see. Ask Einstien.
Well thank you, I just wanted to see if my understanding was correct........2.3 billion other galaxies is the one that blows my miniscule brain. Yes it's scary.
2.3 billion seems a rather modest estimate actually, closer to 100 billion and perhaps many times more within the 'observable' universe alone. But don't be scared. Andromeda is the only one we're likely to collide with any time soon, but probably not for another 2.3 billion years . . . at least.
You mention the Andromeda galaxy, Nohorn, and the New Scientist magazine published material claiming IT contained a trillion stars within it. There are believed to be 100 billion such galaxies in the universe, so there may well be one hundred billion trillion stars all told. We are just a minor planet associated with just a very minor one of these. Insignificant, indeed!
