What will be the ultimate end of this universe and why?

Well we've been through and ice age and a flood. I am guessing our planet will go up in a bid ball of fire...explains the ozone layer hey?

Plate tectonics?  The sun running out of hydrogen?  You people are nuts.  There is a freaking BLACK HOLE at the center of our galaxy!  Who is going to save us?  Who will stand up and protect the next generation from this threat, a threat that will not only crush us and stretch us out over millions of light years, but convert all our precious bodily fluids into pure energy!  It's a fate unthinkable, all of our precious carbon, poof!  Doesn't anyone care?

Nobody really knows for sure.\n\nThere's a theory that the universe is expanding in a spherical shape and will continue to expand until it reaches maximum entropy. At that point all of the energy and matter in the universe will be equally distributed and the universe will no longer be able to support life.\n\nThere's another theory that the universe will expand (again, roughly in the shape of a sphere) until all of the galaxies exhaust their kinetic energy. At that point the universe will begin contracting. When the contracting is complete a singularity containing all of the mass in the universe will form and explode in a big bang.\n\nIf you think about it, if the latter theory is true then it's possible that the universe has expanded and collapsed an infinite number of times in the past!

THE WORLD WILL END ON DECEMBER 23RD OF 2012. I KNOW THIS FOR SURE AND IT HAS NOTHING TO DO WITH JESUS, ALL YOU RELIGOUS TYPES ARRE GOING TO BE REALLY DISSAPPOINTED. THERE IS NOTHING BEYOND DEATH, EVERYTHING IS NATURAL, NO SPIRITUAL WHATSOEVER

end times is not the same as the earth will be done away compleatly.  i agree that it'll be here forever.\n\nthe end times is about the end of satan's run.\n\nthe BIBLE is alive, so, no it wont be old fashioned.

Hell no, all humans will die from some crisis or big disaster, or maybe the earth will be swallowed by some black hole (Actually it's happening) scientist found out that our galaxy is being sucked by some Massive black hole.\n\nI just don't want to be there when it happens :D

Probably find a ship graveyard.\n\nNo...for real...I don't think it is possible to reach the edge of the universe.\n\nPrint this out, then if it happens, you can say, "I told you so."  :)

What happens if heaven is here on earth and we are wasting our precious time wondering where we are going to go next.  The universe I think is a God like creation of infinity upon infinity exploding and imploding in a constant merry-go-round of momentous force started by an almighty, power-full, special entity,......God.  So close your eyes and dream your dreams, we are all part of God and the universe, they are both one and the same, immortally eternal....

I'd say the end of the world !!

No one knows if there is an end of the universe. Remember the "Big Bang Theory" is, of course, just a theory. However, I think the universe may be growing into something, just like diffusion. The universe is growing into a space that no human mind is or will be able to comprehend until we create technology great enough to get out of our galaxy, out of our universe, and into something more. Something so far, far away that we most likely will not have enough technology to get to in our lifetimes or in many generations to come. It will probably take hundreds of years for humans to travel to another galaxy and back safely, but probably thousand to millions of years, if the human race still exists, for us to get farther - into something more, the land beyond.

Milliways?\n\nAnyhoo...\n\nExcuse the geek humor.  It depends on what you mean by the end of space.  If you mean the destruction of the universe, there's a lot of theories out there.  If you mean the physical edges of the universe, there is nothing, no vacuum.  The universe is all that exists, there is nothing outside it.  It's a difficult concept to visualize sometimes.\n\nSome end-of-the-universe theories include the big crunch where the outward movement of the universe reverses itself and returns to a common origin; the opposite of the big bang.  Opposite of the big crunch is the quiet freeze, where the universe keeps expanding, planets drift so far away from each other, entropy takes control, all energy is slowly expended and the universe drifts into a quiet soft end.  Those two theories depend on the cosmological constant.\n\nThere's also a theory where many of our cosmological constants which define the laws of physics and allow for the universe to exist could change and matter simply crumbles at its most basic level (even quarks, which are base atom components, would fall apart).  Another somewhat worrying theory is that physicist working in supercolliders could set off a quantum vacuum collapses, this off course assumes that the quantum vacuum is not at is lowest stable state which is unlikely.\n\nOne of my favorite theories is the result of M-theory, otherwise known as Brane theory.  Brane theory suggests that the laws our universe is governed by a "membrane" created from supersmall (Planck length, 10^-35 meters) one-dimensional strings.  It's easiest to think of the piano, music is created but is not tangible, it is created from vibration of strings.  The way this membrane is folded creates the laws and constants that govern our universe.  There could be, literally millions of membranes and millions of universes.  The theory goes onto suggest that our universe was created from the collision of two membranes; and so too could it end that way.\n\nThere's a lot of different theories, if you're interested in end-of-the-world/end-of-the-universe theories I'd recommend you visit Exit Mundi, linked below.

I do not believe you could ever find the 'end' through the knowledge we have today.  This would require us to exceed the speed of light, obtain infinite energy, warp space as a blackhole does, etc.  I do believe there are infinite universes.  Our universe exists as a 'point in infinitely dimensional space.  \n\nOur universe was created from the chaos of the lawlessness of nothingness, we could have been 10 billion times larger in mass or the size or total mass of an atom.  We may be able to difine how much mass the universe has, but possibly never the size.\n\nIt would be like defining the size of a dimensionless point.

I won't win points for originality by saying that the world will end as the sun expands as it gets older and becomes a red giant. As this will happen in 6 to 7 billion years time, it is not an immediate concern. There are various scenarios for the end of human civilisation or the end of life on earth but that is the most likely scenario for the end of life on earth.\n\nNo-one has a clear idea of how the universe will end. The most likely scenarios are:\n\n* the big freeze where the universe will expand so much that it is unable to sustain life;\n\n* the big rip where the universe will will expand so much that it eventually disintegrate into elementary particles; and\n\n* the big crunch where the universe stops expanding and starts contracting.

No, the entire known gravitational forces of the universe will collapse

if only someone really knew, I think the universe never ends.  I would really hope that we would find new planets outside our own solar system and we would really find other planets like Earth.  I still have time to pay attention and hope they continue to explorer.

I think it would be naive to think that we are the only intelligent beings in this vast universe. Of course it would continue to exist. And as far as anyone knows, the boundaries to this universe may never be reached by human beings. Also, you are correct in your statement that human beings will become extinct. I say this because we only need to look at the dinosaurs. Excellent question!

Well, it depends on your definition of "end." Are you referring to when humans can't live here anymore? Do you mean when the planet itself is utterly disintegrated? Are you referring to a Biblical apocalypse?\n\nTo any of these conditions, no one can say. However, to the first one listed, our continued destruction of the environment continues to lead to more polluted air, ground, and water. And, while the melting of the ice caps will raise water a great deal and wipe out coastal cities and land, it certainly can't cover the entire planet. Stubborn as humans are, we'll probably find some way to survive through technology if we mess things up that badly, which would be extremely sad to have destroyed such beauty. We also might start a nuclear war that kills everything but cockroaches, but the planet itself would still be here. \n\nCondition two, where the planet is disintegrated, could be brought about by several ways, as well. A large comet, asteroid, or meteor might smash into earth, breaking it apart and causing it to no longer technically be a planet. When the sun finally goes nova (estimated to be 5 billion years away), if it reaches this far out, which his possible, it would swallow the earth, likely blowing it to bits. Then there's always the "Hitchhiker's Guide" route, where we'll be destroyed for an intergalactic highway.\n\nAs for the Bible, only the Father knows. Not even Christ knows when it'll happen. People have been incorrectly interpreting the signs for hundreds of years, so all the tabloid doomsday people are probably just as wrong now.\n\nIn short, no one can see the future, and you're right. We don't take good care of our planet. We really should appreciate it more while we still have a planet to enjoy! Who knows, tomorrow someone might throw a nuke, so go out and enjoy earth! And just in case someone doesn't start World War III, go and take care of it, too, so that generations far into the future can look back on this time and say, "Wow, look at all they did for their children and their children's children," instead of, "How on earth could they be so selfish and uncaring?"
