Saint in Paradise Posted 8 April, 2009 Share Posted 8 April, 2009 these 3 galaxies looked like that http://blog.wired.com/wiredscience/2009/04/galaxytriplet.html :cool: Link to comment Share on other sites More sharing options...

Durleyfos Posted 8 April, 2009 Share Posted 8 April, 2009 I didn't realise the hubble telescope had been around that long. Link to comment Share on other sites More sharing options...
Hamilton Saint Posted 8 April, 2009 Share Posted 8 April, 2009 Correction. It's not "400 million years ago" (a measure of time), but 400 million light years away (a measure of distance - how far light would travel through space in 400 million years).

Colinjb Posted 8 April, 2009 Share Posted 8 April, 2009 Correction. It's not "400 million years ago" (a measure of time), but 400 million light years away (a measure of distance - how far light would travel through space in 400 million years). In effect how things looked 400 million years ago. Ladies and Gentlemen, welcome to the world of time travel..... Link to comment Share on other sites More sharing options...
Baj Posted 8 April, 2009 Share Posted 8 April, 2009 Correction. It's not "400 million years ago" (a measure of time), but 400 million light years away (a measure of distance - how far light would travel through space in 400 million years). Correction. Your perspective is determined by your distance and therefore time from the subject. This is exactly how it looked 400 million years ago, however in order to see the subject in one view, you would need to position your perspective so that it was all in your field of view at the same time, therefore you could never view these galaxies at the same time, as they are right now it would be impossible, in fact on a micro scale, it's impossible to hold a conversation in real time with someone anywhere other than exactly where you are, your now is not the same as someone elses now. Imagine viewing a calendar from one light year away, it would display april 8th 2008. An alarm clock from 1 "light minute" away, would show 1 minute before, 1 "light second" away would show 1 second behind etc. As you can see, you can take this down to a microscopic level to conclude that your perspective of any item is not of now, but in relation to the amount of time it takes light to travel from the article to the viewer.

Hamilton Saint Posted 8 April, 2009 Share Posted 8 April, 2009 In effect how things looked 400 million years ago. Ladies and Gentlemen, welcome to the world of time travel..... Right. A different way of looking at it, but you're correct. Link to comment Share on other sites More sharing options...
St Landrew Posted 8 April, 2009 Share Posted 8 April, 2009 I could look at that picture and consider the distances, time, and light speed. The matter, the strong and weak forces, etc.. but I can't divorce myself from an overriding feeling of how unimportant the human race is in terms of the universe. We're here by a random chance in evolution. The conditions became favourable, the tumblers clicked into place, and life got underway on a tiny speck of dirt that is 7/10ths blue on its surface. The odds against me typing this are astronomical [what else would you call it..?]; but flash forward the necessary 4.5 billion years, and suddenly I feel oddly special, instead of unimportant. I suppose, humble is the best descriptive word I can use. Link to comment Share on other sites More sharing options...

But, on the other hand, you could say that humankind is quite exceptional for the way its consciousness and scientific knowledge has developed to the point where our understanding of the cosmos permits us to look out into deep space, grasp what is there, and measure its awesome dimensions so accurately.

In a sense, I believe I alluded to that by suggesting I could appreciate the time, distances, etc.., although you are indeed saying more than that. These are unalterably manmade measurements on a dynamic universe. The universe appears to behave in a tick-tock way, and yet has no guide, aside from its beginning and continual flux. And if humankind was a flea riding on an elephant's back, we'd be hugely more influential in the universe, and have real presence. How long is it to 4th April 2063..?
