Here there! If you're reading this, you're most likely a human being! If you're not, then, by all means, let me know about your species in the comments.  Anyway, since you're most likely a human, your life span is, I dunno, give or take seventy years, now, to a fruit fly, you're an immortal. Why, if they were any smarter, they would probably worship you. To a bristlecone pine tree however, your life is ridiculously short. why, if moses himself planted one on his time, of would still be alive and "kicking" till now.  However, both you and the bristlecone tree will eventually end. The earth will eventually end. Religious texts paint the end of the earth to be quite dramatic. Well, we'll see, won't we? As scientists, we must look further. To the very ultimate end. The end of our universe. I know what you're thinking. "That's ridiculous, how am I supposed to enjoy eternal life in heaven if the universe has an end?  " well, like I said, we shall see. Anyway, without wasting time, let's get to some of the astonishing ways scientists think the universe could end. Keep in mind though that these ends aren't due in about a googol years. That's 10100. If you've not had your fill of eternal life by then, I want to meet the architect. The big crunch.  That sounds funny.  Anyway, the idea is that our universe is basically an elastic ball which is totally under the influence of the forces within it. And as such, the big bang, caused it to explode and become so vast into what it is now. And that gravity will reverse that. It basically means that the universe will soon start contracting because of gravity pulling things together. Soon, galaxies will start colliding with each other, and black holes the size of entire clusters will pull the entire universe and "crunch" it. And that's it. No more photons, quarks, and in short everything that makes our universe what it is. All that will remain will be an infinitely dense singularity.  The big rip  This is even funnier. Anyway, this is the exact opposite of the above. What of gravity is not enough to make the universe contract?  I mean, we already know it's a weak force. And Hubble recently discovered that the expansion of the universe was actually accelerating.  Now, do you know what happens to an elastic ball if it keeps expanding? Yeah, boom boom. The universe explodes in a very gory event. Every single atom, shredded. Light and electricity, destroyed. Baddass explosion. H-bomb is a learner. The big smash Well, no one knows how the the universe looks like from the outside, so . . . no pics. Anyway, this is just basically that our universe is not the only one out there, that we're actually living in something far bigger than we could ever hope to fathom and that there are others right there with us, and that one could collide with us. Resulting in a big smash. Transforming our universe into something else entirely. Forget gravity, forget quarks, and stuff. Our current universe will merge with the other drunk one that wouldn't look where it was going. effectively ending the universe as we know it.  the HEAT DEATH  This is also called the big freeze . . . but I figured, the big was getting too much. It's also called thermodynamic equilibrium. Anyway, you're probably wondering why I put the black screen up there, well, that's exactly how the universe will look like after the heat death. Here is how it works. The second law of thermodynamics states that energy always diffuses when it can (basically.) And this basically means that the universe is moving towards a state where energy is so evenly spread that heat no longer exists! Heat is defined as flow of energy due foi difference in temperature, but imagine if the temperature was the same everywhere in the universe! that means no heat! And without heat, fusion cannot occur, hence, no stars, everything will go dark, nothing, will be able to happen, particles will just bounce off each other with no exchange of energy. Force will cease to exist. And the black screen above will exist. Forever, and ever, and ever more.  One cool thing about this is that, energy basically spreads when we work! You grab?" So, by being lazy, you're actually prolonging the life of the universe! How considerate! So, from the board of universe lifespan prolongation(ULP) we say, Thanks for keeping it cool. Thanks for taking it easy. Thanks for being lazy. And thanks for reading. Cheers! |

Going from the postulations you gave, it is fallacious to say the universe will end. Going by your point given as the "HEAT DEATH", Where everything as WE know it becomes a dark void. Well, that doesn't mean the universe no longer exist, it only means life as WE know it has ended and a new phenomena is about to start, a new existence alien to any knowledge known to man or any species occupying this old universe? The universe can't come to an end because of some scientific presuppositions and astrological explanations. Before t he Big Bang or Creationism and evolution, the universe has always been here but life as WE know it is what continues to evolve. Do you know that Before the Pre-Classical era there was organised societies and explanation to human and terrestrial existence? Well, the universe is a myth to man, it has always been since the time of the early men. So Mate, the universe won't cease to exist, only life as WE know it will be altered.... ALTERED!! 1 Like |

Some hypothesis sounds crazier than crazy ..As of now tho galaxies are colliding on each other swirling in a beautiful galactic dance. . Huge galaxies form when smaller galaxies collide into each other, there actually is a hypothetical postulation that places the milky way in a colliding course with Andromeda... anyway that's not my problem, i would be dead anyway so about these universal end postulations, i find the second one more plausible than others. . . with the farther space expands (because it actually isn't just matter expand but space) the gravitational force might not be that strong enough to hold loosely held matters so it just might collapse under it's own self.. Whether the universe is eternal, not eternal or semi eternal is not my business cus we'd probably be dead before then anyway 2 Likes 1 Share |

Freemanan:in physics, we define the universe as the space in which the current laws of physics apply. If the space were to change, such that those rules no longer applies, we state that such a universe no longer exists. In short, it is dead. So, you're right. Just that we're dealing with different definitions of universe. |

johnydon22:yeah, right? I'm just concerned . . . you know, with this eternal life, and what not? |

Teempakguy:Exactly... Meaning is a problem in science.... |
| Re: How Will Our Universe End? by johnydon22(m): 8:38pm On Aug 22, 2015 |
Teempakguy:Eternal life? lol... That shiit will be crazy boring!!!.. Do you know why life is so important to us now? Because we know we are mortals that shiit doesn't last forever that's why its so precious to us the little time we have. Every moment, every blink, every joy and pain so precious because it will never come again, and every breathe taking the candle closer to the end.. 3 Likes 3 Shares |

llaykorn:no.  But it seems like a nice song . . . |

If The universe decides that it's had enough and wanted to check out then I would think "The big rip" would be it's most likely exit strategy, I basing on the fact of what we've observed and confirmed, that the universe is expanding exponentially and will eventually rip itself apart. Remember Occam's razor " The simplest answer is often correct ". |
| Re: How Will Our Universe End? by Nobody: 9:43pm On Aug 22, 2015 |
khalhokage:oh yeah? What about newtons's flaming laser sword. "If something cannot be settled by experiment, it is not worthy of debate."  Anyway, the big rip assumes that the universe' elasticity has a yield point. What if it doesn't? What if it can go on expanding forever? Also, remember that the universe is still quite young. What if it is still growing? We know dark energy is responsible for the expansion of the universe, and it soon might run out, causing the universe to stop expanding. All of this make the heat death a very worthy contender, you know? |

There's no way one can be sure of anyone outcome. Too many variables to consider IMO. 1 Like |

You guys have come again! According to science,I may not know how the whole thing will pan out.But going the biblical way(Revelation 21:1),heaven and earth will pass away and it can be inferred that the universe will not remain either! Someone may ask:why always link our existence here and hereafter to the Bible? But I say the Bible is a book of knowledge and truth;it contains God's plans.Science might bring up the possible ways the universe will end,but sure,it won't alter God's plan! |
| Re: How Will Our Universe End? by seunot: 9:32pm On Aug 23, 2015 |
Lmao. Of all the hypotheses, only one sound very likely; THE HEAT DEATH! However, with adequate knowledge life will continue after "the universe end". With Time, Life will master Energy, Matter, Gravity, Dark matter and Time itself all via acquistion and application of Knowledge. Eventually, Life will be able to created and modify 'new universes'. Ultimately, LIFE TRIUMPHS!!! |

Its non of my business. So far i pay my bills and I solder my panels, what concern me and death of universe? Who knowing date of death don help?? On the contrary, i think going by the fact that the universe is expanding bla bla bla, it should die the HEAT DEATH & Yea, our galaxy will collide with Andromeda, but it wouldn't hurt. #Wishmymindwouldbe.electronically.preserved to witness the beautiful and harmless collision |
| Re: How Will Our Universe End? by Blakjewelry(m): 12:17pm On Aug 24, 2015 |
@teem I think the whole hypothesis are nothing but one. After the big bang, the universe begins to expand. The energy from the big bang is what is still sustaining the expansion of universe today. It is theorized that it is either it will continue and eventually everything will fly away and cold out or at a point it will exhaust the energy and begin to slowdown and eventually collapse under gravity. Note. The the reason gravity is weak is because it is thought that some of it force is leaking to other universe. Once that leak can be established, then we can stand tall and say other universe exist |

You guys wanna make me go back to school and study physics but no thanks, I will pass.. I think the chance of Human experiments ending the universe is higher |
