Here is a topic where I hope you will all discuss how you think the Universe will come to an end, or if your opinion differs, feel free to explain what you will happen.

My opinion is that the universe will eventually "burn itself out" so to speak. The eventual heat death of the Universe is long and boring, and I don't feel like quoting Wikipedia, only to be told I was quoting Wikipedia, so here it is if you want to read it:
http://en.wikipedia.org/wiki/Heat_death_of_the_universe

Though this eventuality has worked its way into my mind, some doubt has recently arisen in me. Scientists have recently made a discovery which could prove the existence of multiple Universes. This could really put a damper on the heat death theory... Anyways if you guys have any theories that you believe in please tell me what they are and why! While you're at it go ahead and tell me why you think I'm wrong!

I was planning to make a thread similar to this soon, but you beat me to it. I'm glad I'm not the only one thinking about this.

I completely agree on everything burning itself out. All stars will eventually become white dwarfs which will after many many years become black dwarfs once they extinguish their remaining energy, or a black hole, which will decay over time, or a pulsar. Basically in the end, we'll run out of heat. Everything is also slowly distancing from each other.

I haven't seen the article yet on multiple Universes. I'll have to check that out and come back to this thread.

I agree, but, I don't think this will happen for millions of years. It takes a while for things to burn out. Like a star, for example. They can live more than a thousand years. Too bad I probably won't be alive to watch the world burn.

I might also add that there is a theory of galaxies colliding into other galaxies. That's crazy.

Much more than millions. Stars can live for millions, or even billions of years. White dwarfs will take an incredibly long time to become black dwarfs.

I think the "Big Rip" is the most likely scenario; where galaxies and atoms just tear themselves apart because of the acceleration of objects in the universe.
And I do believe that Dark Energy plays an important role in the stabilisation of the current state of the universe and possibly the destruction of it, depending on what its properties are.

This article has a pretty neat and concise explanation: http://hubblesite.org/hubble_discoveries/dark_energy/de-fate_of_the_universe.php

Yes it may happen eventually but i would say not for at least a few billion years... And the theory of galaxies colliding is no mere theory... As i sit here typing this the Milky way galaxy (where we live) is on a collision course for the Andromeda galaxy. Though this collision won't happen for millions of years it is very unlikely that this would cause the end of the universe, though maybe it would be the "end of earth" (bonus points if you get the anime reference).

Yeah that's all i had to say.

read the spoiler for a good laugh... boy am i glad i read up on the big rip before posting... That could've been potentially embarrassing... The spoiler was my argument before reading up on the big rip. Some could still be valid assuming gravity does not eventually rip itself apart... Excuse my narrow minded rant because i was definitely not considering all the possibilities.

1) I don't think we have the senses to measure anything like that.
2) Earth will be gone before the universe, if the universe will actually disappear.

why don't you think we can measure something like this? I'm sure that if we learn enough about the nature of the universe then a whole world of information would become available through scientific research and testing... Who would've ever thought space travel would be possible before the 20th century. Why is it so hard to believe we would know enough about the universe to predict how it might end?

I remember a Futurama episode where they did the death of the universe as a joke, but the more I thought about the situation, the more depressing it got. In Futurama, the universe dies and then is reborn in another big bang scenario, called "Big Crunch" on wikipedia. But the reason why I felt it was a bleak view of the universe is because all the horrible stuff that has happened will be repeated over and over again.

In the show Farnsworth shoots Hitler and laughs about it because he claims that doing so would not effect the timeline. But it's not so funny to me because that means things like the Holocaust and countless other tragedies will be repeated endlessly.

I prefer the Heat Death theory over Big Crunch for those reasons, but just because I might prefer it, that doesn't mean that evidence will support it.

If the universe is constantly expanding and at a highly accelerated rate which is increasing then I can only imagine that matter would accelerate to a point where it is turned back into energy. We know that matter and energy are two sides of the same coin and it has been proven that matter can become energy. With a massive abundance of energy could it be possible that it could once again become matter and in a sense give birth to a new universe? The big bang theory is based on energy becoming matter anyways. It could be recycling itself over and over again. I know a bit about astronomy but am by far no expert so what I said could be entirely not possible, its just my opinion based on what I know.

PS. not all stars become white dwarfs

That is also a possibility, though i would have to say I am pretty skeptical of it... I don't know much about the conversion of energy to matter and vice versa but I do know there is a lot of matter in the universe. I mean a whoooooole lot of matter. On top of that, it is all moving away from a center... Assuming that the matter of the universe could be converted to energy due to massive speed, it would fly off into nothingness... Scratch that thought. What happens to gravity with no matter? I know that a hydrogen atom ten thousand light years away from me does effect me gravitationally because it has mass... What if everything with mass were to be converted to energy? What happens to the laws of physics that we have come to know (not that it would matter to us at that point).

Just some food for thought.

well Einstiens theory of E = mc2 does show us that matter and energy can become one another if matter is accelerated to the speed of light squared. Just think about this, for all the matter that is out there there is just as much energy, and there is plenty of energy that is not matter that we know of. Its part of the reason why if you have a radio and cant pick up a signal there is still static. Its been some time and this may be the wrong term but if I remember correctly I think it is called the cosmic microwave background radiation.There is still sooo much we don't know about the universe though, like why is there a super massive blackhole in the middle of our galaxy, and every galaxy we know of

Ok I think I explain this once before so I do not feel like repeating it for this thread, so short version.


Universe is Expanding, after some time long after earth sees to exist, the universe will start to reseed / shrink . Once all the matter has gather in a small point the heat and pressure build up from it will create what is known as a BIG BANG, this lead to a new Universe being created from the old one, this has happen before evidence can be found by glancing at the Super giant Black Hole found in the center of are universe.

This is also known as the big bounce theory, and it is what most as in 98% the scientist at this time agree on.

The combined immature stupidity and self-important smugness of the users of this forum will expand and bring about the heat death of the known universe. Hopefully starting with the Jesus freaks first!
