Ok cool Now raise your hand if you can name the planets in order of closest to farthest from the sun? “Hopefully not many”- remark about how little we know about space or at least care to know. Well that's true in a sense for astronomers as well as they continue to debate our rules about quantum mechanics, how things are and aren't, and how space just likes to say nah i'm good to any type of rule we place”EXAMPLE, BLACK HOLE SUCKS UP ALL LIGHT YET NEW PIC SHOWS LIGHT” so as you can tell we know relatively little about our known universe and the how and why things happen in it. This happens to be especially true for these keywords which is positive you've heard somewhere before. The existence of dark matter and energy which the theory of their existence is the only thing that lets me tell you of this but that's for later.
For now let's head back to one of my first question: “are you scared of space” now would you change your mind if i told you space is going to disintegrate you atom to atom and then destroy those atoms till their are gone and there's absolutely no way to stop it. Ok ok i see a lot more hands and you may be wondering wait hold up now my dude you said space is coming to whack me what does that even mean? Well, I will tell you how, why, and when it will happen.
Briefly let's talk about what happened first rather than last. First, we all know that the big bang created the universe and did a bunch of funky stuff to be cool but what we really want to know is if the rate of expansion is increasing or decreasing in the universe and is dark energy ,quintessence ,vacuum, or phantom energy. Now the first question is whether or not the rate of expansion increasing decreasing or manbey even staying the same as each one of these would lead to a different and very dire outcome. but for time let's say the universe is expanding at an accelerated rate. This is where the term dark energy really comes into play as it is known that dark energy is responsible for this acceleration. Now as I mentioned earlier there are three different “types” of dark energy and a specific for each term. Well the outcome we are talking about is called “the big rip” and is the result of dark energy being in the state of phantom energy.
The big rip
The big rip is an end of universe scenario in which the equation of state is less than-1 and phantom energy accelerates the universe's expansion rate infinitely resulting in galaxies, stars, planets, even gravity itself are pulled away from each other at an infinitely increasing rate until all matter in the universe is ripped into its smallest particle possible. Why would this happen now well it's all because our equation of state or W. Now according to Kalbacn publishing co. “if the equation of state is less than -1 and dark energy is phantom energy, the universe would become increasingly dark energy-dominated and acceleration would increase. When playing out this scale factor(the relative expansion of the universe)blows up to infinity. As the scale factor grows larger than the hubble distance, galaxies will begin disappearing beyond the horizon of the observable universe. Phantom energy will strip apart gravitationally bound objects. Everything in the universe that is held by the gravitational force will dislocate. The horizon radius shrinks to a point, and all matter will rip apart. First the Local Groups of galaxies will be ripped apart, followed by the milky way. As phantom dark energy continues to increase it will rip our planet from the sun, roughly a year before the end of the universe. About 1 hour before the end phantom energy will tear the earth apart. But it won't stop their.
After all gravitationally bound objects are ripped apart, and just fractions of a second before the end of the universe, phantom energy will rip apart all objects held together via electromagnet and strong forces. These objects include molecules, atoms and subatomic particles then the universe will end in a singularity, but a different sort of singularity than the big bang and big crunch in this scenario instead of all matter and radiation being squashed together all the universes components would be ripped apart to infinity.
Conclusion
Well that's how the universe will end and keep in mind that we have no way of stopping this from happening and that this is only one of the plethora of ways the universe could end. Buuuut it won't happen while any of us are alive as it is predicted to happen in about 29,768 to 32,000 years so i guess you could say if the average life expectancy stays constant through that time 376 to 405 generation will have passed with nuke man probably ending on the 50 generation so we will more than likely not even be around to witness the true end of all absolute annihilation
Its just a theory based on theories to explain things we don't know to hydrate our thirst for knowing what we don't know will happen.and you'll be dead by then anyway so it doesn't matter unless you figure out how to become immortal then ur possible theoretically maybe going to be ripped to shreds by a big crunch or if u figure out how to stop it, then you should be up here talking not me.
That's all I have and thank you for listening to me ramble on about this.
