Hi. Just joined the forums. I've not taken a physics class since high school, but it is an interest of mine, so forgive me if I'm way off on some of the science. Please tell me if I have any of these facts wrong: - The universe is about 13.7 billion years old. - Our light horizon is roughly 27(?) billion light years across. - We estimate the diameter of the (known?) universe to be around 46 billion light years. - The oldest/earliest galaxy we've ever seen is from around .9 billion years (of the age of the universe). - The very earliest galaxies are estimated to be from about .3 billion years - We have estimated the size of the universe by looking at the earliest/most distant galaxies and then calculating how much the universe has expanded since then. If my numbers aren't far off, is it just serendipity that we have been able to see almost to the beginning? If humans had developed to the point we're at now about 1 billion years ago, would we be able to see almost to the big bang? I've read the first few hundred thousand years had no photons. I hope this makes sense to someone.
