Backtracking 1

If you couldn’t tell, yesterday I went and talked to my cosmologist friend. It was rather ‘interesting.’ I learned quite a bit, and hopefully I shall continue to learn more. But to continue…we shall start with our timeline of the universe. But I think we shall go backwards…start with the present. So we have this universe. We can only see a small part of it (because of our horizon), and I’ve included a picture of what it looks like (it’s on a logarithmic scale). And if you download Google earth, it has a sky function and you can zoom in and see all the stars, it’s very fun. But anyway, when we take a catalog of the red shifts and the things we see it appears the things are moving away from us. But we already knew this from Hubble. But what we’ve found recently is that those things are moving away from us at faster and faster speeds. This is a bit strange cause you would think that after the big bang and inflation stuff would start slowing down. But what we are seeing now, with our infinitely advanced technology, is that the expansion of the universe is speeding up. And they are going really really fast. They are actually leaving our horizon. And you know what this means, this means they are going faster than the speed of light! Yep space, as we speak may be expanding faster than the speed of light and leaving our horizon and thus, our field of vision. This is the universe we have right now.
