Topic: How do you think the universe will end? (Read 6745 times)

Universe is actually a multiverse, once universe will die a new one will be created. The cycle goes one. The universe is basically like an atom.

Weather will completely change and people would live shorter. There would be scenario like from Waterworld movie...That's my opinion...

Heat is caused by collisions.  Eventually everything is spaced so far apart there are no more collisions.

We can never be 100% certain of anything, but all the knowledge we accumulated makes it about as likely as that every shit I take is really a black hole in a parallel universe.

so it is, since we seem so sure. can you say it definitely isn't?
it just seems that we hypothesize/theorize/find a new particle or subparticle every other year or so

Converted in to energy (photons) by black holes that attract the mass and then evaporate hawking radiation.


ahm. no . We have a pretty good idea of what an atom is nowadays

What would happen to said mass? Degrades (expands?) to pure energy? Sorry didn't watch the video

That would be interesting since maybe each atom is a big bang in and of itself

My guess is that it will "end" with both a big bang and a big freeze, as they are essentially the same thing in the absence of mass. Mass which would no longer exist in the very distant future in a cold empty universe and didnt exist at the time of the big bang.

Dont take my word for it though:

Will this happen in our lifetime?

Thank you for the detailed explanation. I feel like I have a better grasp of the concept now.

Yeah, this is the most popular theory at the moment I think, I'm no astrophysicist but I'll explain what I know.

Historically, the "Big Crunch" was what most scientists believed. This involved a "Big Bang", an expansion of the universe, then after a while the force of gravity would slow the expansion down. Eventually the force of gravity would overcome the initial force of expansion, causing the universe to begin contracting. This contraction would accelerate, ending in a spectacular "Big Crunch", with all the matter in the universe trying to occupy a single point. Some then speculated that another "Big Bang" would occur, and the cycle would continue.

However, in 1998 the Hubble Telescope observed some distant supernovae which showed that, a few billion years ago, the universe was actually expanding more slowly than it is today. Many more experiments have shown this to be true - The universe seems to not only be still expanding, the expansion is actually accelerating. Now this threw the "Big Crunch" theory out of the window, and caused scientists to make new theories involving something called "dark energy". Although no-one really knows what dark energy is, most scientists believe it's a mysterious energy which repels matter, overcoming the force of gravity (which attracts matter to other matter), and causing the accelerating expansion of the universe.

With these discoveries, it seems that the "Big Freeze" or heat-death of the universe is a likely scenario. In this theory, all matter keeps getting further and further apart, and eventually reaches maximum entropy, where all the energy is spread evenly throughout the whole universe. In such a state, there would be no heat or light, as there wouldn't be enough concentrated energy to sustain the processes. It would be very dark and cold.

However there is the "Big Rip" theory, which I admittedly know very little about, which predicts that the accelerating expansion of the universe will cause it to tear itself apart as a result of dark energy becoming stronger over time. The idea (I think) is that as dark energy gets stronger, it begins to tear apart smaller and smaller objects, until it is strong enough to tear apart subatomic particles, in essence destroying all matter in the universe.

1. Scientists will soon prove that blackholes cannot exist. This theory is partially correct regarding the fact that it doesn't end.

2. Wrong. It does not expand forever. Something will most likely happen after the galaxies slows spinning and gets under a particular limit.

3. Stupid theory. the expansion is slowing down at this stage. it is not accelerating.
Dark matter supports the existance of matter. It is not anti-matter.



My theory: I will publish it after very much research.


Don't worrry, before all that our Earth will end.

I've read up on number 2--the big freeze but can't really wrap my head around the physics of this. Would anyone care to explain like I'm 5 the theory behind the big freeze aka, heat death of the universe?

It won't end, it will last forever well at least fix it when it is going to break..

2. Big Freeze-  The theory says gravity will not stop the expansion of the universe.  Since it keeps expanding forever, eventually all fuel will be used up leading to the heat death of the universe.

Even Solomon of the Bible said that the end of a thing is better than its beginning.   

You really think so?

end is good

It will end badly, no matter in what way....

Alien invasion, they ran out of place to stay...
