How the Hubble Deep Field Was Taken

life is somehow essential in mars ..

At this moment across the other side of the universe other beings may be viewing the stars that died to gave us our heavy elements. But will they have Pink Floyd?

@tomkaten

We will alwasy be seeing stars. That what causes the expansion is due to dark matter. Which only if not mostly exists between galaxys. Dark matter is like antigravity but honestly thats just the only way to describe it.

Positive non anti gravity is what we experience inside a galaxy, a galaxy is like a gravitational storm of stars that will go on forever.

cut myself I want to die, emo boy

Today we have technology to make new elements. Just changing the number of the atoms components.

And if the expansion in indeed accelerating, our fate is pretty grim. A couple of billion years from now, we won't be seeing a thing in the sky. Anywhere... Nothing... For eternity... On our way to the big freeze or big rip, whichever comes first.

I know it's a bit of a cliche, but it's a pretty dreadful perspective.

But since other things will get us, as a species, much sooner, there's really no point in worrying about that at this time :P

It's fascinating!!
But i have one doubt:
If the ultra deep field picture that was taken it's 47 billion light years far away, how the universe is 13 billions years old, if nothing is faster than light?
I mean, how those galaxies are 47 billion light years distant if the edge of the universe couldn't be farthest than 13 billion years?
How?

Guda, it's because the fabric of spacetime expands faster than the speed of light. At least that's what the redshift of the most distant galaxies in the visible universe indicates.

Some of the farthest objects in the Universe will never be visible to us, since light can't match the speed at which the source distances itself from us and will never be able to travel the required distance.

so Tomkaten, are you basically saying that the galaxies were 13B LY away when the photons left (the photons which we're seeing now) and that, after all this time, now they are 47B LY away?

You got it. Quote from a very know encyclopedia:

"The age of the Universe is about 13.7 billion years, but due to the expansion of space we are now observing objects that are now considerably farther away than a static 13.7 billion light-years distance. The edge of the observable universe is now located about 46.5 billion light-years away".

All a bit beyond human comprehension, I know, since we're used to much smaller scales. It's the expansion that's making it hard to process.
