Browsing the web to waste some time, i saw this.
http://www.bbc.co.uk/news/science-environment-11580789
It says that the tiny dot shown is the furthest galaxy ever viewed, and as such is the oldest, due to the distance it is away from us means it takes the light emitting from it longer to get to us, in this instance light emitting from it has taken 13 billion years to arrive at Earth.
So to my thought, to surmise, the closer the galaxy appears in the image, the newer it is - that much i can get my head around.
But since it's fact that the universe is still expanding, galaxies still moving around, what is to stop the same galaxy appearing twice in the same image, once as a relatively close, large object that they conclude is from say 5 billion years ago, but then also as a smaller, much fainter image that is say from 10 billion years ago.
But the thoughts there now and can't get rid!

Plus they'd also have other information on the galaxy.
The interesting thing is the two versions we would see of this galaxy, one getting closer to us would be getting older (or, in your description, a newer view of it), and one moving away from us getting younger ("going back in time", or in your description, getting an older view of it)
I bet you wish you just had your original thouht now...
Haha, to be honest i wish i had looked at porn instead of the BBC site in the first place!
What I have never understood is, we are told the universe is still expanding well what is it expanding into? And how big is that ?
haha.
It isn't. It's just expanding.
Ok but what was there before the universe expanded ?
Marshmellow
Ohhh now i understand :thumb:
There wasn't
The bible puts it quite well, if you edit out the superstitious bits:
"In the beginning [...] there was light"
On the other hand, there are those who think that the big bang may have been preceeded by a big crunch, in which case you could consider that a "time before time" and hence in some ways could be seen as "a before"
At least "a time before time" makes some sense i can get my head around that, but its mind boggling that something can be created from nothing its just like thinking of the biggest possible number there is no end to it and no real answer
Another random thought - As a young child, did you develop an opinion, thought, concept etc... that you later found out to be quite a profound thing, i'll explain.
I've always had this thing, where, well i'll put it in to a scenario; Say i've just took some exams, and i get a letter through the door with the results, until i open that envelope i could either have passed them or failed them, and perhaps this stems from some sort of OCD, but i always imagine that in the moments leading up to me realising that the envelope is there, my behaviour determines the out come, if i say slap my brother around the back of the head on the way down stairs, walk in to the living room and see the envelope, then the outcome is less likely to be a positive one.
It was only after several years of thinking about this, that the outcome of something isn't a reality until you "open the envelope" and make it fact, that i discovered that, isn't this the basis for quantum physics? that both scenarios are true but one only becomes a reality when observed? - i guess the only difference is i some how believed my behaviour to have an impact on the outcome.
Just seems bizarre that i would random develop this idea as a 7/8 year old without ever having heard of quantum physics
Think i must be in a random mood tonight, i sound like i've been smoking weed all night or something.
Okey dokey, it's definately the morphine making me stupid, dint understand a word of that, lol... Thanks any BG..
Think I should try get some sleep while it's working.
:chin:
However, as you look at progressively larger scales, the probability of anything other than what we'd expect is extremely small. But this is besides the fact that the results had already been determined before you even opened the envelope. It does however explain why your envelope didn't just spontaneously materialise in the room by borrowing energy from the universe
