Ultimate Fate of the Universe
« on: March 03, 2009, 09:49:18 PM »
Ultimate fate of the universe

As with interpretations of what happened in the very early universe, advances in fundamental physics are required before it will be possible to know the ultimate fate of the universe with any certainty. Below are some of the main possibilities.

Big freeze: 10 to the power of 14th years and beyond
Main articles: Future of an expanding universe and Heat death of the universe

This scenario is generally considered to be the most likely, as it occurs if the universe continues expanding as it has been. Over a time scale on the order of 1014 years or less, existing stars burn out, stars cease to be created, and the universe goes dark. §IID. Over a much longer time scale in the eras following this, the galaxy evaporates as the stellar remnants comprising it escape into space, and black holes evaporate via Hawking radiation. §III, §IVG. In some grand unified theories, proton decay will convert the remaining interstellar gas and stellar remnants into leptons (such as positrons and electrons) and photons. Some positrons and electrons will then recombine into photons. §IV, §VF. In this case, the universe has reached a high-entropy state consisting of a bath of particles and low-energy radiation. It is not known however whether it eventually achieves thermodynamic equilibrium. §VIB, VID.

Big crunch: 100+ billion years
See also: Big Crunch

If the energy density of dark energy were negative or the universe were closed, then it would be possible that the expansion of the universe would reverse and the universe would contract towards a hot, dense state. This is often proposed as part of an oscillatory universe scenario, such as the cyclic model. Current observations suggest that this model of the universe is unlikely to be correct, and the expansion will continue or even accelerate.

Big rip: 200+ billion years
See also: Big Rip

This scenario is possible only if the energy density of dark energy actually increases without limit over time. Such dark energy is called phantom energy and is unlike any known kind of energy. In this case, the expansion rate of the universe will increase without limit. Gravitationally bound systems, such as clusters of galaxies, galaxies, and ultimately the solar system will be torn apart. Eventually the expansion will be so rapid as to overcome the electromagnetic forces holding molecules and atoms together. Finally even atomic nuclei will be torn apart and the universe as we know it will end in an unusual kind of gravitational singularity. In other words, the universe will expand so much that the electromagnetic force holding things together will fall to this expansion, making things fall apart.

BONUS: Big Bounce: The Big Bounce is a theorized scientific model related to the beginning of the known Universe. It derives from the oscillatory universe or cyclic repetition interpretation of the Big Bang where the first cosmological event was the result of the collapse of a previous universe.

According to one version of the Big Bang theory of cosmology, in the beginning the universe had infinite density. Such a description seems to be at odds with everything else in physics, and especially quantum mechanics and its uncertainty principle.[citation needed] It is not surprising, therefore, that quantum mechanics has given rise to an alternative version of the Big Bang theory. Also, if the universe is closed, this theory would predict that once this universe collapses it will spawn another universe in an event similar to the Big Bang after a universal singularity is reached or a repulsive quantum force causes re-expansion.

Plus my Birthday theory says I'll live past 2012 that something will happen when I'm 28.



NOTE: This was done back in Oct. 2007 I was 17 at the time.


So using Windows Calender..

I was born Presidents Day(1990) - Then 6 Years later it lands on it again.
(Which is a Monday) Then 5 Years .. Then 6 Years again.. then 11 Years.. Then back - So 6,5,6,11, Repeat.

11 + 6 + 6 + 5 = 28

I have 11(9 years now) Years before It lands on the monday again.

17 + 11 = 28 ((This now would be 18 + 10 = 28)) [[ 19 + 9 = 28]]

CONSPIRACY?!?!!?!?!?

Well i don't like any of the universe ends theorized (mankind will be destroyed in all of them  :( ). I just hope that mankind, billions of years in the feauture, can escape this cruel fate, :-\ maybe in another universe :)

well, there isn't any scientific evidence that we will die in 2012 :D

You can however trust in gods or aliens destroying the Earth if you want, but we didn't notice anything ;)

There is a asteroid that is going to hit the west coast of Mexico on April 13 Friday 2027. If it misses then it will hit West Coast of Africa in April 13 Friday 2036

Oh I see.

Which most likely won't hit the Earth.

If Jupiter didn't exist, there would be alot of comets [and some asteroids (I think)] hitting Earth.

Will the superclusters and galaxis die when the universe dies, freezes, rips and crunches?

No, only the crunch/rip.

The Milky Way and Andromeda if they collide we will name is Milkomeda.
Just found it in a wiki article.

Well, you have to add the freeze too: after billions of years stars will die very often but new stars will be born less frequently. At some point will just remain red dwarves and black holes, and after that nothing, so galaxies will die too... Cruel world!!!  :P

By then we will be long gone.

All galaxies merge called Virgo Super Galaxy
Other supercluster merge to Super Galaxy

superclusters are...

Planet>Solar Systems>Galaxies>Clusters>Superclusters>Universe

So, a supercluster can't make a galaxy.

But in 100,000,000,000 years thats it ;D
its filled with red dwarfs and small amounts of white dwarfs

as seen from wikipedia
100,000,000,000: The Virgo Supercluster merges into one super galaxy, millions of light-years across, filled with Red Dwarfs and small amounts of White Dwarfs. Other superclusters have also merged, yet have been separated from each other by distances of more than a billion light-years due to the acceleration of Dark Matter and Energy.

ohh... i get it now. but i thought you ment many superclusters MADE a super galaxy, not merge to make.

I would guess that the universe would recycle itself. It's possible that it's happened billions of times, with different results. Different physics and such. Like gravity. Maybe it's here just this time around. Stars and galaxies might be a new way the universe came together. Who knows. The universe is infinitely hard to think of.
