    Default Is the universe dying?

    Is the Universe Dying? - Universe Today

    Is our 13.8 billion year old universe actually in its death throes?

    Poor Universe, its demise announced right in it’s prime. At only 13.8 billion years old, when you peer across the multiverse it’s barely middle age. And yet, it sadly dwindles here in hospice.

    Is it a Galactus infestation? The Unicronabetes? Time to let go, move on and find a new Universe, because this one is all but dead and gone and but a shell of its former self.

    The news of imminent demise was recently broadcast in mid 2015. Based on research looking at the light coming from over 200,000 galaxies, they found that the galaxies are putting out half as much light as they were 2 billion years ago. So if our math is right, less light equals more death.

    So tell it to me straight, Doctor Spaceman(SPAH-CHEM-AN), how long have we got? Astronomers have known for a long time that the Universe was much more active in the distant past, when everything was closer and denser, and better. Back then, more of it was the primordial hydrogen left over from the Big Bang, supplying galaxies for star formation. Currently, there are only 1 to 3 new stars formed in the Milky Way every year. Which is pretty slow by Milky Way standards.

    Not even at the busiest time of star formation, our Sun formed 5 billion years ago. 5 billion years before that, just a short 4 billion after the Big Bang, star formation peaked out. There were 30 times more stars forming then, than we see today.

    When stars were formed actually makes a difference. For example, the fact that it took so long for our Sun to form is a good thing. The heavier elements in the Solar System, really anything higher up the periodic table from hydrogen and helium, had to be formed inside other stars. Main sequence stars like our own Sun spew out heavier elements from their solar winds, while supernovae created the heaviest elements in a moment of catastrophic collapse. Astronomers are pretty sure we needed a few generations of stars to build up enough of the heavier elements that life depends on, and probably wouldn’t be here without it.

    Even if life did form here on Earth billions of years ago, when the Universe was really cranking, it would wish it was never born. With 30 times as much star formation going on, there would be intense radiation blasting away from all these newly forming stars and their subsequent supernovae detonations. So be glad life formed when it did. Sometimes a little quiet is better.

    So, how long has the Universe got? It appears that it’s not going to crash together in the future, it’s just going to keep on expanding, and expanding, forever and ever.

    In a few billion years, star formation will be a fraction of what it is today. In a few trillion, only the longest lived, lowest mass red dwarfs will still be pushing out their feeble light. Then, one by one, galaxies will see their last star flicker and fade away into the darkness. Then there’ll only be dead stars and dead planets, cooling down to the background temperature of the Universe as their galaxies accelerate from one another into the expanding void.

    Eventually everything will be black holes, or milling about waiting to be trapped in black holes. And these black holes themselves will take an incomprehensible mighty pile of years to evaporate away to nothing.

    So yes, our Universe is dying. Just like in a cheery Sartre play, it started dying the moment it began its existence. According to astronomers, the Universe will never truly die. It’ll just reach a distant future when there’s so little usable energy, it’ll be mostly dead. Dead enough? Dead inside.

    As Miracle Max knows, mostly dead is still slightly alive. Who knows what future civilizations will figure out in the googol years between then and now.

    Too sad? Let’s wildly speculate on futuristic technologies advanced civilizations will use to outlast the heat death of the Universe or flat out cheat death and re-spark it into a whole new cycle of Universal renewal.
    Is the universe dying? Oh sht!

    The universe is exanding, and there's little reason to doubt the effect of that, the measurements taken have some leeway but are fairly consistent. But still, its based on measurements made in a timeframe that is essentially meaningless considering the size of the universe.

    A heatdeath does seem most likely, but it's not quite fact yet either.

    Perhaps the universe and all we know about it is merely in the throes of a single heartbeat.

    Here's an interesting read:

    Does gravity operate between galaxies? Observational evidence re-examined | Proceedings of the Royal Society of London A: Mathematical, Physical and Engineering Sciences

    Most interesting about it is how it essentially mentions the fallacy of observation within a frame of reference that is potentially outside of the perceivable scope of observable reality. (I think I may have butchered this sentence too much...)

    Basicly, what we observe might not be enough to allow us to comprehend the entirety of the framework the universe operates in. (little better I think)

    What I take from it is that we still know very little and the future of the universe is still very much an open question.

    I once entertained the thought that the big bang might not have been a singular event, but a continuous event passing by out part of the universe 14 billion years ago, with the implications that the universe might be an indeterminate but potentially near infinite amount of time older than currently known. It would be able to explain both the reason of the exanding universe as well as dark energy (not dark matter). There are plenty of issues with that idea of course, hence it is merely a thought I entertained, as well as the fact there's (as far as I know) no way to test any of it, but it does feed on the fact that some of the assumptions astronomists are currently making (by say of what makes most sense), aren't entirely infallible either.

    Basicly, there's still plenty of room for thought.

    There's plenty of articles on the internet that say the lights in the universe are going out. Doesn't that make you wrong?

    Besides, you think that dolphins have gills, which discredits your education level a little.

    Keep reading articles on the internet. Any astronomer will tell you there is no reason to doubt that the universe will eventually suffer heat death, but no astronomor will tell you that that is an absolute fact.

    I said that dolphins are descendant from land mammals and evolved back into the sea as something we could consider trying to do if waterworld becomes reality. I never said anything about dolphins having gills. Lol.

    We have to save it, using the Power of Love.

    Care Bear Stare! lol If we could just get back to Marshmallow Glee Land, I think we'd be much better off.

    I was right!

    So dolphins are devolved people? lol

    ^just kidding. Sorry. I know it isn't funny the third time.

    Okay, so, I'm in a dying universe. What is going to happen to me?

    You will die looooong before it will die.

    Most likely, unless there is something we don't know about keeping it alive, in which case only you will die.

    Take that universe!

    But if it is dying right now, even though it's still got a lot of life in it, doesn't that affect me?
