Id just like to say one of my other theories. Its to do with space and the universe/s.
Since we are talking about origins of life on earth and the alternative routes I began to think about space, the bigger picture in a way.. Heres some thoughts..
I saw this picture on Nasa's site of a black hole and to me it looked like as if the black hole was acctually just a hole in the 'end'/'side' of the universe and that it lead onto another universe through the gap.
I heard once that theres this thing called anti-matter that is the opposite of matter. So it technically does exist but its acctually nothing and we cant see it etc.. It's 100% efficient. Now from anti-matter, it can easily convert into matter eg, our universe. If theres anti-matter can there be an infinite amount since you can find anti-matter inside universes that have been created through the change from anti-matter to matter. Maybe there are universes in our universe. Sometimes I think that the universes that are created outside of our own through anti-matter overlap, giving it the feeling of the infinite size. I said before that the universe each could have more anti-matter inside each one, which create others and this keeps on going on each time a new one is made. So maybe there is a continuous amount of space/universes since they are just being created all the time.
Again, these are theories and i'm only 15 so you may think this is just the idle mind of a teenager, but its what I can believe/comprehend space best through.
Also if anyone else knows more facts/evidence that this may be wrong or inaccurate, I would like to hear from you.
I like to base my theories around ready known facts and then build on them. Right now I don't know much about space. (or time) I don't want to steer of course..
Thanks in advance.
