@@ildar5184 I guess the thing would be that galaxies stop accelerating away from us, giving us more of a chance to contact them, rather than waiting until they start accelerating towards us to reduce the distance. Assuming FTL travel is impossible, and that near-light travel is too unfeasibly difficult, we'd just need more time to be able to reach other galaxies. I'm not exactly sure how much time, but it would help if things weren't moving away from us faster than we can move towards them.

In my mind, Gravity, Dark Energy & Dark Matter are all due to the Higgs Repulsive Force. The Higgs pre-dates the Big Bang, an event I view as the birth of a flare, rather than a bang. A theory I call the Condensate Flare Theory. Gravity is repulsive, the Higgs Repulsive Force. The Higgs, well near pure Higgs, empty space, is at ground state & in Condensate. It repulses everything else. As matter is locally bound energy its component energies are repulsed in multiple directions, & it in effect does not repulse, so the Higgs does the next best thing & pustules matter together. Dark Matter is the Higgs Repulsive Force, well the pustule tension between pure Higgs (Vacuum of Space) & corrupted/dirty Higgs in the pustules (Dark Matter Halos). Dark Energy is the Higgs Repulsive Force.

I've always liked the idea of the Big Bounce. It's much less scary to me. Circle of life. New beginnings. etc... Before the discovery of the accelerating universe, I had just assumed that the universe would eventually collapse from gravity and crunch into another Big Bang.

The Big Bounce is the one that makes the most sense to me. If energy can neither be created nor destroyed, it would surely transform and start again rather than reaching a finite end.

[@bewilderbeestie]

You forgot a bit regarding the Big Freeze: just because everything's at a thermodynamic equilibrium, quantum effects still apply. You still get virtual particles appearing and disappearing. The more complex the particle, the lower the probability, but the probability never becomes zero --- which means that if you wait long enough, macroscopic objects start appearing out of the vacuum. You have to wait really ridiculous lengths of time before anything interesting appears, but nothing's happening; you literally have an infinite amount of time available. Objects of the same complexity as a human start appearing every 10^10^50 years (yes, that's 10 to the power of 10^50); go look up the Boltzmann Brain concept if you want to have trouble sleeping. But it gets even weirder. Particles with enough energy to form a new monobloc, that is, a new Big Bang causing a universe appear every 10^10^10^56 years. As there are only about 10^10^115 possible universes, almost immediately (on these timescales!) you reach a point where _every single possible universe_ has been created. And each one of those expands, reaches its own Big Freeze, and starts spawning universes of its own...

[@smallw1991]

You are discussing 10^10^115 possible distinguished sets of laws of physics I think. If the universe is infinite, there are infinite possibilities. The poincare recurrence time for our projected finite universe size though is 10^10^10^10^10^122 years if anyone was wondering

[@DanBeech-ht7sw]

People have always sought for a kind of neat answer, geocentrism, heliocentric, steady state, oscillating universe. We are always confounded by the reality. Professor Weinberg showed that any successive bounces would have ever increasing proportions of matter to energy, resulting in slower, more sticky expansions. That matter would be left over from the previous crunch. Now the proportion of matter to energy in the Big Bang appears to be 0:100 at time 0, which means that IF we lived in an oscillating universe, this is the first expansion. There was no previous crunch. Which creates a science and philosophical problem, what happened before, if "before " has any meaning.

A funky thought, As you transition past the event horizon of a black-hole, "toward the singularity" becomes a timeline, rather than a physical place. We do have an event horizon in our universe, just past what we think of as the big bang. What if the expansion is just us falling toward the center of this universe's singularity? And.. if expansion is increasing, perhaps there's an asymptotic function for the external-universe's (the universe outside ours) distance-traveled per unit time of whatever makes up "us" (if such a thing could be said to exist)... we experience more time the closer we get to the center... hm.

[@cinnis5670]

Assuming the big bounce is the future of our universe: would it be possible for the atoms I'm made out of, well could they like come back together in a future universe? Maybe not the atoms themselves, or even the quarks, but the energy that makes up those particles.

If there is a multiverse, and a universe can be recreated over and over, there would be infinite time. And when you have enough time, everything will happen, even then most unlikely scenarios.

Infinity could go both ways, so if what you are saying was true, the probability of atoms rearranging before and us remembering that, would be possible.

A big crunch leading to a big bounce feels poetic. The universe we've been given doesn't seem to care much for poetry, but it'd be nice to have a future where it becomes something better. Pressure makes diamonds and all that.

[@Rileylego-fq6wc]

The big crunch makes the most sense. I mean, what goes up must come down. So if the universe is expanding thats just it "going up" in all directions. Then eventually once it hits the peak of the arc it all "goes down" in on itself. You can send the nobel peace prize to me in the mail.

[@Delta-u5f]

Idk why but I find peace in the idea that eventually everything dies and nothing else happens. Every cosmic titan ceases to exist and the violence of fighting to survive ends. Like the ending of a book that I struggle to understand with larger concepts my brain strains to understand, a relief that it’s over even though I enjoyed some of the time I was reading.

[@thekingofmojacar5333]

Roughly speaking, our universe goes through 4 stages or cycles and then everything starts again from the beginning... The 4 main cycles: 1. Infant universe - 2. Expanding universe - 3. Contracting universe - 4. End cycle = collapse of matter To claim that the universe will one day "die" completely is, in my opinion, adventurous. I assume that these 4 cycles of existence repeat themselves again and again and represent, so to speak, an endless, eternal process... ⚖ When I look at the almost perfect functioning of our universe, I come to the conclusion that the universe has already gone through several complete cycles of existence. If we analyze the current evolution phase, it´s simply too well organized and advanced...

[@katiebarber407]

knowing the truth is still always nice, right? id rather knkow than not know. maybe finding out leads us to a way to somehow send a probe at just the right moment to somehow escape whatever happens, allowing humanity to leave a remnant of our several billion year existence into the stars try not to be so shortsighted. we're all members of the human race, a global species with the potential to colonize solar systems, or even galaxies. i tend to think this shortsighted "it doesnt affect me so i dont care" mentality is reponsible for so much suffering

[@MARIOMAKER-wk8vy]

​​@@aceyboyYes, but you and I would be too dead to care about existing if we don't, and if everything is truly random, odds are if we do exist again, we won't remember existing in this life. The only thing that we can (and should, for that matter) care about is what we will do in this life, for we have no 100% certain answer of what we will do (or be able to do) in the next plane of existence.

What blows my mind more than anything is - why is there anything to begin with 🤯. We can only really contemplate things that begin and end. How did stuff come from nothing... and what even is nothing... and if there was always something, how did it get there? Great video by the way 🙂

[@erikbosma8765]

Even worse,,, why is there nothing to begin with?

[@MaidenLoaf]

What'll really boggle your noodle is, why should we assume there was a beginning? That would be placing a finite limit on an infinite timeline. In a similar way, asking "how did it get there?" if there is no beginning is really asking the same question in different words, because the point at which it all "got there" is, by definition, the beginning.

[@CARBON10]

It has always been here and will never end, your comment is dam amusing I have to say, it does not end ever, there is a strange book telling this never ending story, and even though it's hard to follow and it's full of absolutely the craziest stuff imaginable, aliens, monsters, magic ,and even humans, it could be the truth, so it does go on forever

Big Bounce is the name of the game! Based on my (unsubstantiated) calculations, were are now living in the era of the 23rd Big Bang. Too bad we don't know if life developed in any of the previous Big Bang eras. But we should find out the next time around if we can learn to become immortals before the next Big Bounce.
