Dubbed the eXtreme Deep Field, or XDF, the photograph represents the deepest view of the universe yet achieved, giving astronomers a “time tunnel”-like glimpse back across 13.2 billion years of cosmic history.

wow, like specks of dust, or beautiful jewels

At 16:20 you can see a Hubble image that shows gravitational lensing, a bit like this one:
This one shows the effect even more clearly. The arcs are the images of galaxies that have been bent by a large mass (another galaxy say) closer to the telescope, or in the case of very distant objects by all the matter in the space between:
In the case of one closer mass causing the bending, we can estimate the mass of the object or galaxy by measuring the degree of lensing. The mass of the stars we can see in such objects doesn't account for all the mass that causes the lensing. This is evidence for what we call dark matter.
For distant objects, the light can take a convoluted path…although it is still traveling in a “straight line”, it is the spacetime through which it travels that is distorted by gravity:

the first time I have seen those pictures many years ago ,at first it looks like kayos ,all things flying all over ,but then I start to think on creation ,an soon realise that there is not one thing that is does not need to be there,and all things are useful to each other and feed on each other,all this is from My God ,my creator .wonderful.
how more men learn from creation materiel how more it proves that it needed a creator ,it is so complex that it would still take many years an many men to come to a conclusive reality of the understanding of Gods creation
Hi T,
You do understand that many of those objects, even entire galaxies, occasionally collide with each other.Tim

timdo you ever wander that what ever happen out there as to happen the way it is happen now for reasons we do not understand yet ,figure out that all the wars ever made could have been prevente ,and so totaly useless,but for some reason their is an understanding and a reason ,

You speak of collisions as if it were a mistake. When you bake a cake, the ingredients need to collide in order to create something new from the individual ingredients.Thanks Stu.
Also travelling along the circumference of an eternal circle is a straight line. My question (not to you in particular) is: does an eternal or infinite shape become finite when viewed in a higher dimension.
For example: A 2 dimensional plane can host an eternal number of 1 dimensional lines, but only one eternal 2 dimensional plane. Likewise an eternal third dimensional space can host an eternal amount of 2 dimensional planes, but only 1 eternal 3 dimensional space.
So can an eternal circle be a finite circle viewed higher up or an eternal sphere be a finite sphere from a higher dimension?
Does infinite become finite as we step up a dimension.
If not, then why does the logic work from 1 to 3 dimensions and not further.
And there are planets which could be made of Diamonds!

Really? What on earth was he talking about? Perhaps you could explain it to me.Stuart

I don't think Tim was implying any kind of mistake, was he? This is all just gravity working on the matter that it made. Gravity has a particular habit, but it doesn't have intent.The Andromeda Galaxy will collide with the Milky Way Galaxy in 4 billion years from now. From our point of view that is purely academic knowledge because it is unlikely there will be much life left on earth past 1.4 billion years from now due to the increasing luminosity of the sun.

this would contradict that collision theory in my view

A fair point. The answer is that the Andromeda Galaxy is relatively close to us and moving through space towards us, just as other galaxies close to us are moving through space away from us.Hubble's Law, which is what you might be thinking of, isn't really talking about galaxies moving through space. Hubble's Law says that the further away a galaxy is the faster it is moving away from you, but the catch is that this is not movement through space but apparent movement because space itself is expanding.
Not easy I know, but can you see how there are two mechanisms that give the impression that a galaxy is moving? Andromeda is close, and is actually moving through space towards us. Because it is close, it doesn't appear to be moving away from us very fast at all due to space expansion, and so the actual movement through space towards us is the much faster thing.

stuso the speed in space is not a constant like they use to believe
it seems that fatality is the religion of the scientist
if their calculation are right ,
if their understanding is full on it .
if what they understand is true ,
so only fatality is the forecast,
just like to know that if you jump in the deep cool water you drown ( if no one was there to help you out )many IF's
