This is what i had read on what Theoretical Human had posted on page 3 (is it?)

Anyway, I had read the magazine "Astronomy and the main topic is:
"Dark Matter/Energy"

Dark Matter/Energy has been with the universe after the first galaxies had been created. It is testified that the Dark Energy comprises of more than 90 % of our universe (theory) today. The proof is that the galaxies began to move far from each other. Why? Because Dark Energy is an energy on which it battles the cosmic power. It is theorized that in a billion more years, the universe will completely reverse itself and destroy anything except for stray particles and begin a new one. It is called the "Big Crunch"

PS

And sorry for the title, I omitted "Typographical Error on which i typed, Does the Universe has and end? It should be "Does the Universe has an end

If our universe is a flat or open universe, the bug crunch will not occur.

I had also read that all the things in the universe including blackholes to be the last will evaporate.

There are two expected effects in the future:

1. The Big Crunch

2. Evaporation

Evaporation? Where everything evaporates( i meen everything ) into nothing??

Took the words right out of my mouth.

Actualy, it should be "have", not "has."
"Have" is the ownership or property or whatnot, "has" is for having done something.
I believe so, atleast.

Anyways, I don't believe the universe has an end.
That would require complete destruction of... something.
I find the idea of something being destroyed hard to imagine. Changed, removed from perception, sure, but not actualy destroyed.

Well, i wouln't worry to much about the universe ending anytime soon (non-biblicle outlook ) beucause the reason that planets and stuff are moving away from eachother s becuase of the effects of the big bang, i.e the explsion is still throwing us back, but eventually gravity will reverse this trend of moving away from other planets... this will only happen in a really, really, really, long time. So i wouldnt worry to much.

edit: the earth will be long gone by the time of this reverse by the way, sun blowing up and all.

I've formed opinions about maps that don't exist. So what?

Well, according to the mathematical equations made by Einstien, there was no time before the universe exsisted, and there will be non after. So in that sense the universe has a begining and an end. Because time itself is defined by the movements of things in relation to one another, if the universe "crunches" there will be no movement because everything will be crushed up as much as possible, which would theoretically break them apart, and thus there would be nothing to move.
I've never heard of the "evaporation" theory. If it's stating that at the end of the universe, everything will become energy, or evaporate into nothingness, this goes against the end all law of entropy. The way to use energy is to change its form into less usable forms. There has yet to be an efficient way to transform it back.

My only opinion is the ff: (answering the opinions)
Source: Astronomy



It is caused by dark energy. When things had gone far from each other including hydrogen and other things, they begin to dwindle and eventually, be destroyed lasting the black holes for they have a long lifespan



Maybe, maybe not. What if they find a habitable place beside earth?




Einstein is a great physicist and mathematician. Although because of modern technology and simulations, some other things that einstein had said was proven apocryphal(false).

These are just my opinions, feel free to post.

I'm sure eventually they will build something on another planet for people to go live on, it's just a matter of time.

My theory related to physics based on how the Universe might end goes like this:

As we all know, the Universe is spreading out thus all bodies are being spread afar from one another.
Since the bodies are being spread out, less gravity will act on every body thus accelerating the separation even more.
The Universe has a finite amount of atoms because the Universe is a finite sphericall space that if placed on a plane, if you pass the edge you will appear on the exact opposite spot.
Since gravity will keep diminishing to such an extent that all celestial bodies will start to go at very high speeds thus expanding at incredible speeds and at first colliding.
Then comes the atomical part. Because there will be such a diminutive insignificant amount of force acting on the atoms spread accross the Universe and given that all atoms can have radiation, the absense of gravity will thus alter the electrons making the gravitational pull of the nucleus far more intense than any other force thus causing the electron to crash into the nucleus expulsing radiation (alpha, beta and gamme particles) which will eventually collide into other atoms causing a massive Nuclear Reaction.
Gravity will increase so fast that the central point of the explosion will start to pull on the bodies thus making the universe shrink.

Now I just have to prove it.

Well if everything has a beginning or end, the universe may slowly be ending. Well true that we may escape this planet to civilize on another one, we cannot escape. And the fact that the sun is going out in a few million/billion/trillion w/e years, that may also be a factor in it. But some of you might be saying, "What about the other suns in the damn universe. Our's is not the center of the damned universe", just remember, all damn suns have a damn end.

I have heard from physicists that have studied the galaxies and such and have claimed that we are moving faster and faster. So if we are expanding faster, then the chances of being pulled back together are very slim.
I believe the universe goes on for ever, so if you went in one direction, you would be going in that direction for eternity.
I used to believe that if you went over the edge, you would be at the opposite edge, but that was when I 8-year-old, so I actually had no clue what I was saying/thinking.
And if the universe did have an end, its not like its going to be a giant brick wall that you can't pass...

lol it would be like an invisible wall in a map!

Space is infinite! Theirs no end, no beinging, no purpose!

if the universe is really infinite, then its 2 alternatives

1. all atoms exist only "near" us and everything besides that is black

and now for the interesting one..
2. the universe is really infinite,
the chance of humans living on earth, the exact distance from the sun. the exact size of all the planets and moons. and what organisms existing there. is so small you cant type it by number, but you understand what i mean.
now if the universe goes on forever everything that has a chance, has a existence. meaning if you see far enough away you will find infinite of solar systems EXACTLY like ours. and almost exactly in everyway technically possible, f.ex a couple thousand years more or less advanced.
everything that has a technical possibility of existing exists, so there is a infinite amount of different aliens.

i mean everything must exist, so on some planet so many lightcenturies away you cant type it by number you have a computer with your exact starcraft folder.

and somewhere they have a staredit.net with this exact same post

The universe does have an end. The universe is slowly using up all of its energy. The stars will eventually lose all their heat. All this built up energy is called entropy. Eventually all the stars will become big smoldering rocks.

IMO Everything that has a beginning has an end and vice-versa.

There would still be energy, of a different type, or more matter from that energy, even supposing new stars aren't created.

If the universe DID have an end, everything would start all over again, exactly the same? Or would it be another one of those theories where there is a moment and you choose to do what, and all those things?

If the universe DIDN'T have an end, everything would dissapear sooner or later? Or would the planets, stars, etc. just be floating around 'til, who knows when?

And aproximately how old is the universe? I just wanted to know.

I believe the universe ends when Judgement day comes

So, if its just this universe that ends we can just move to a different universe!



Well I belive if u can tell how old the center of the universe is then you know how old it is! By my guess I think like 5 times over trillions of years old.



I thought you can't use up energy, I thought energy was mearly used and then recyled to a different form of energy.

Most people believe that. I've actually gone out and studied particle physics and energy itself. The truth is energy isn't nescesarilly being *used up,* but there are many different variations as to how to lose it. For instance, I bet you didnt know youre just a huge grouping of charged particles made of other charged particles made of other charged particles....simply put, you're compressed energy. The reaction between certain types of energy and it's compresed forms (matter) is what creates the complex world you see before you. Hell, its what makes you who you are.

And I believe what Gradius means by the fact that the universe is losing all its energy is that theres a matter of thermal energy...Thermal energy is just about the only energy that spreads naturally. Stars will spread their heat. Planets will spread it. Every thing with heat will spread it. If heat did not exist in an object, that would mean that it would be at absolute zero, more or less energyless. Wave some air at it, its gone, gonna fall apart. Even empty and matterless regions of space still posses thermal energy. So via Thermal energy, energy will spread itself through space, creating a "lost energy" effect. But as for what happens after this point, I'm not too sure. the Big Crunch is most likely to happen, but its not the end. Its just a rubber band effect. The rubber goes out, then in, then out again. Our universe will Bang, then Crunch, then Bang again from the resulting colisions. Once again, what happens after this is we'll eventually spread out all the energy via heat, but after that, I'm clueless.

I might be wrong, you know, but this is just an educated and hypothetical guess. Plus, I've studied this stuff for a bit, so I'm pretty confident in my theory.

Depends on who you ask.


Well, you lose that bet

To clear this little matter up, in an earlier post, I showed how one would lose energy because of the thermal energy type, and yes, that does also have to do with kinetic energy. All energy effects one another. So thorugh the loss of heat energy, do only real energy left would be gravity, and you don't just lose that out of nowhere, that takes even longer to lose, so since there would still be an existance of gravity, the Big Crunch is still a possibilty.
