Evidence of Big Bang May Disappear in 1 Trillion Years
SPACE.com ^ | 4/13/11 | Clara Moskowitz

Posted on 04/13/2011 8:47:56 PM PDT by NormsRevenge

While astronomers are largely baffled by the question of how the universe began, they should probably hurry up and figure it out. In the far future, most of the evidence will be long gone, a new study suggests.

Though future astronomers will likely have the benefit of advanced technology and a more sophisticated understanding of physics, they won't be able to take advantage of the last vestiges of evidence left over from the Big Bang. The trace signals from the explosion that set the universe in motion 13.7 billion years ago will likely be all gone 1 trillion years from now, the researchers said. ..

However, researchers have identified some backup clues that our distant descendants (if humanity is still around) could use to trace the history of the universe.

A lucky time

Astronomers today can look at galaxies more than 13 billion years away that were formed only millions of years after the universe began. They can also study the so-called cosmic microwave background radiation — a pervasive light in the cosmos that was created by the Big Bang and still lingers on.

However, in the distant future, these clues won't be visible to scientists on Earth or its near environs. The cosmic microwave background light will have faded away ..

And because the universe is expanding, the ancient galaxies that are now just within our field of view will be too far away to see from future Earth. ..

However, all hope for future celestial sleuths is not lost, because future astronomers might be able to study the Big Bang through so-called hypervelocity stars that have been flung out of the Milkomeda galaxy.

These stars will be the most distant light sources visible to astronomers in our galaxy in the year 1 trillion A.D. (C.E.).

"if humanity is still around"

It seems virtually impossible that humanity would be around then considering not only would our own star have gone supernova hundreds of billions of years earlier, but I think our galaxy will also be gone by then as well. Considering the distances we're talking about, it's unlikely we would be able to escape it.

How can we see the light from a galaxy 13 billion light years away unless we are moving at least the speed of light away from it? IOWs how did our galaxy get ahead of the light coming from a galaxy that is supposed to be closer (or was closer) to the center of the explosion everything is supposedly moving away from?

Really! They say the Universe is around 14B years old, earth is maybe 4B, and they are worked up over something that will happen in 1T years?

Some people have way too much time on their hands (pun intended).

At one time, the theory of the so-called “Big Bang” (thought up by a theologian) was too religious for irreligious scientists, who actually used to think that the universe itself was eternal and had always been there. Then observable red shift proved the theory. (Whoops.) Since then, they’ve been scrambling to secularize the theory somehow . . . desperately . . .

IOWs how did our galaxy get ahead of the light coming from a galaxy that is supposed to be closer (or was closer) to the center of the explosion everything is supposedly moving away from?

The Big Bang created space. Put two dots on a small inflatable balloon and then inflate it. Those dots move away as the balloon inflates. If one dot radiates light it can be received by the other dot, even though both dots were "created" at the same time and didn't even move on their own (neither our galaxy nor our star system have engines, though they may have relative speeds.)

This also puts the limit to how far we can look in the Universe (you can't see things before Big Bang, and distance = c * t.) So 13.75 ± 0.11 billion light years it is. This also means that farther objects are unreachable and unknowable to us at this time; the light from them is still traveling toward us.

There is more discussion here.

The red shift proves expansion. Logic dictates that expansion indicates a singular point from which the expansion began. We can not understand why the periphery is accelerating rather than slowing after the bang. It is a dark matter or dark energy thing.

If a singularity caused the expansion it had to exist in a specific point/time/space.. Thus the eternal universe theory.

Both theories are valid, and both are not within our capability to conclusively reconcile. We call these things we can not comprehend dark or black. Not a racial thing, just acknowledgment that we can not see what is happening. Some of the newer thinking goes along the lines of there being a time when there was no time/no space and in fact no possibility of a point. The singularity. One can easily lose ones mind thinking about this stuff.

Once on a star in a remote corner of the universe, some clever animals invented knowledge. Then the star grew cold and the clever animals had to die. One might invent such a fable, and still not sufficiently have illustrated how shadowy and flighty, how aimless and arbitrary, the human intellect appears in nature. There have been eternities when it did not exist, and when it is gone, nothing will have happened. - F.N.

Actually I think you cleared it up for me without my going to the link. I have heard that explanation before but not in the context of answering the question I asked. That would mean that from the center of the Big Bang to the surface of the balloon would essentially be devoid of material since it was all blasted away at the same time by the same force. Right?

This also means that farther objects are unreachable and unknowable to us at this time; the light from them is still traveling toward us.

How would that necessarily be so? If light emitting objects existed further than 13 billion light years away yet have existed longer than 13 b. years then the light could be reaching us now. Say; an object 20 b. light years away that has existed for 30 b. years. No?

The rubber of the balloon skin represents the entire knowable universe in all its multiple dimensions.

Imagine (if you will) a balloon made of very thick rubber. This rubber has been printed or doped with a special technique so that it has pictures of stars and galaxies within it.

When the balloon is blown up: imagine that not only the balloon expands, but the thick rubber skin expands ‘sideways’.

That’s the model. Space expanding in all directions and everything IN space - the stars and galaxies - getting further apart.

But don’t think about the space inside the balloon. That isn’t part of the analogy anymore than the air-pump blowing up the balloon is.

Hope this is helpful.

That would mean that from the center of the Big Bang to the surface of the balloon would essentially be devoid of material since it was all blasted away at the same time by the same force. Right?

I'm not a professional cosmologist, but - as I understand it - we don't care if there is any material "farther" from the imaginary inflating shell, or closer to the "center" (whatever those words mean - we must understand that time and space were created in the Big Bang[1].) Bake a loaf of bread with raisins. As the dough rises, all raisins move away from each other; but any two raisins don't care what other raisins are doing - they aren't affected by that. Similarly, dots on a balloon don't care if there are larger balloons outside or smaller balloons inside.

How would that necessarily be so? If light emitting objects existed further than 13 billion light years away yet have existed longer than 13 b. years then the light could be reaching us now. Say; an object 20 b. light years away that has existed for 30 b. years. No?

Yes, with one little catch - the age of Universe is about 13 billion years. So if there is an object 20 billion light years away it can exist only for 13 billion years (even if we assume that it got there instantly[2]) and therefore we have to wait another 7 billion years until the light from it reaches us.

In other words, there is no object in this Universe that is older than the Universe itself, and as result we can't see past the point of birth of the Universe.


[1]Imagine a water insect that can only live on the boundary of water and air. Take a sealed barrel of water. Can such an insect live anywhere in it? No, because there is no boundary - there is only water in it.

Now heat the barrel until bubbles of steam are released. Now you have the boundary, and as long as those bubbles last long enough you just created a bunch of Universes for little 2D civilizations of water spiders to sprout, eventually. And if you rework the whole model one dimension higher you can see how our 3D Universe could "condensate" out of space with higher dimensions.


[2] How could that be? A 2D analogy may help. We know that if you drop a stone into water a circular wave will start spreading, relatively slowly. A water insect, being a 2D creature, can't imagine how something (a wave) can instantly appear everywhere; the insect expects it to originate somewhere and then propagate somewhere else.

But take a large sheet of plywood and drop it onto the surface, flat. It will make contact at every point of its surface at the same time - instantly. The water spider's physics would be shattered - he just observed an instantaneous action without any propagation! But that is possible only because the interference came from another dimension (from above the water.) One theory of BB suggests that BB could be a spark, a collision point between objects of higher dimensions.

Yes, I get the balloon analogy but the question isn't whether the raisins care about what's going on in the center. The question is; there is a center isn't there?

Yes, with one little catch - the age of Universe is about 13 billion years. So if there is an object 20 billion light years away it can exist only for 13 billion years ...

Assuming it is a part of the universe created by the BB. Which I didn't.

In other words, there is no object in this Universe that is older than the Universe itself, and as result we can't see past the point of birth of the Universe.

Unless the light of something much older than this universe was passing through this universe.
