Will the Universe Ever End? | Episode 1304 | Closer To Truth 

Why do most humans not ever ponder these higher mysteries? Most are perfectly content going through life without thinking about these fundamental “laws”. I love the Universe, I hope I never stop having the ability to ponder and observe it.

"Dark energy is a code name for our ignorance". - beautifully and honestly described as scientists do. If only religions could be so honest and pragmatic.

The filming dates of these episodes is really peculiar. This is episode 1304, which means it was first broadcast in 2014. But if you're familiar with what some of these people look like today (e.g. Kaku, Guth, even Robert) it had to have actually been filmed many years earlier than 2014 (Kuhn is currently almost 80 years old and Guth looks MUCH older today than he does here). He's been making CTT episodes off and on since 2000. I suspect a lot of the footage is simply recycled/re-edited footage from many years ago.

Tegmark: "Dark energy is just a code word for our ignorance." My sentiments exactly.

"In the long run we are all dead." - John Maynard Keynes

I don’t understand how this channel has so many episodes of such a high quality, and still not getting a million subscribers. Edit: I thought the numbering system they used referred to the actual number of episodes, thanks for letting me know.

Michio Kaku is always such a drama queen. He knows very well that the Milky Way won't "die in fire" upon merging with Andromeda. Stars are so far apart that it's improbable that any single collision will take place.

The idea of a multiverse where all infinite possibilities occur is terrifying. Because worlds like ours, and worlds far worse than ours will reiterate infinitely. Infinite holocausts, infinite animals being preyed upon, infinite wars and torture. Sure there will also be infinite good things happening. It's still terrifying to ponder.

ETERNAL UNIVERSE Those who say the universe will end may well be underestimating the universe. End? What does that mean in the context of a permanently changing universe? The cosmological constant is dynamically constant. That is, it's unending change. The universe is simpy permanent change: motion, dynamism, transformation, with long periods of slow motions that gives the impression of steady states. Balance and disruption are its behavioral patterns. So where the universe is concerned phrases like beginnings and endings have no meaning. Sentient beings have birth and death cycles. But the universe simply unfolds as it must. Big crunch, cold fading away into nothingness, or escape into multiverses via inflation, all do not signify any end of the universe. On the contrary, ETERNITY is the natural state of the universe, with or without us, or living forms known to us humans. If this does not humble homo sapien sapiens, what will?

This is human concept.. the universe will never end .. it will keep expanding with additions of more galaxies.. how do I conclude this???

I was disappointed at Kaku's discussion of Proton decay as if it is a fact, when he should know that it is purely theoretical, it violates the standard model, and it has never yet been observed.

It's amusing the way people talk about "we", as if human beings will still be around over the time scales they're speculating about!

I find this subject fascinating but sometimes the answers get a bit more than i am able to conceptualize. Saul Perlmutter is always a welcome sight to articulate very heady subject matter in a form i can digest.

I thank you dear sir for “your wisdom held questions”, helps us commoners to learn a lot

"Our Milky Way galaxy will probably die in fire as it collides with Andromeda". Which is contrary to the views expressed by cosmologists. It would be good to have, at least, a simple explanation of the whys and wherefores regarding the formation of 'Milkomeda'.

This is one of the most fascinating and interesting topics that we can ever expect to experience on a platform like RU-vid I am so grateful for this channel

In the next millennium people will look at videos like this and think how quaint it is that we knew so little and troubled our minds with things we knew nothing about. I

Michio always seems so sure of himself. He’s a great speaker but lord kelvin also thought he and his cohorts had all the answers. I’m guessing we don’t even know what questions to ask to find these answers yet.

My theory and opinion aims towards the big Bounce. The universe has always existed, its born, it lives, it dies and its reborn again. After so many trillions, googly years this Dark Energy collapses, and so creates a new big bang. There is for me no reason to contemplate on why its always existed, why its suitable for life, it is as its always been. Im contempt with this. The variables or x amonunts of matter and gravity has been like this in another universe, and therefor its continued in a new born, the one we are living in. It will again bounce back, kickstarting a nw big bang event. Dark Energy as it seems now isnt uniform at all. So perhaps our universe isnt perfect flat either. Nature doesnt like perfection, nothing exists without some in-consistency. This can be adressed to anti matter-matter. If the Big bang was perfect, then there would be equally same amounts of anti matter and matter, and nothing would happen. But nature is with its flaws. Therefor we exist. Its an exciting time, we will discover more and more of our universe and our understanding of its end, birth or rebirth.

I've watched all of these physics documentaries and shows for years and years... I probably seen most everything made... And michio by far is the most proud to be a physicist. Each time I hear him talk he says the same thing... "We physicist think"

The universe will never end. It's got that sigma energy.

It depends on what you mean by "end". All the galaxies will eventually be dragged into their central black holes. Black holes "evaporate" and fill the universe with photons, according to some scientists. Perhaps the photons will "condense" into a singularity until it becomes unstable and go BANG ?

If the universe is destined to disperse into a cold death, then we have two options to explore. First would be to master backwards time travel. Then we could get on the merry-go-round of time in perpetuity and through each iteration acquire more and more knowledge and power. Secondly, we must explore the possibility of moving between universes within the multiverse.

The universe ends when RU-vid runs out of videos.

The show is Just "Wow" A salute to Lawrence kuhn🙏

Even we know it doesn't matter about the end of universe because humans are long gone by then, we still have strong desire within ourselves to know how it ends...

Seriously though, I think it cannot be stressed enough that these are very very very very very long time in future discussions. It has no positive or negative connotation with respect to timescales that we as human species have to worry about. Do not claim that physics is very bleak as it foretells what will happen in such a distant future. Remember it was same in the past near big bang - it was not a hospitable environment for humans then either. Lets not make a big deal of it. And if one wants to go there then let us discuss the concept of hell many religions talk about which are even worse. I guess even the concept of heaven is equally grotesue.

Will unaswerable questions about the duration and size of the universe ever end?

I think it's a fairly standard scientific concept that the universe will end. That doesn't necessarily include a multiverse, but possibly a more pertinent question is 'will existence end' and an answer can only really be speculated on if you suggest existence actually started. I hate to use the word dimension, because it sounds a bit like Doctor Who, but there is a sort of time dimension that trumps all the other dimensions and is at the core of existence. If we perceive it , however fleetingly, it massively changes our symbolic understanding of the universe (and of course all understanding can only be symbolic)

No problem. Bronze and iron age mythologies say humans are the chosen ones and will live forever. Most human beings believe some form of that self-serving mythology.

Gurth’s premise is the most hopeful. Infinite civilisations. And an infinity of them will know (or knew) as much as or more than we will ever know about reality.

What if the scientists think the universe is expanding, but not knowing that it’s actually just breathing, like other creatures, but because we too small one breath takes human lifetimes, then eventually when the universe contracts again scientists will be like “the universe is now contracting”, while the answer is as simple as a breathing mechanism! We just too small to see it.

Thanks so much, I think this episode is my favorite.

Anything bound to time has to end, so does the universe. But, our consciousness is not bound to time

So far dark energy is just a code word for our ignorance. Lol.

Consciousness means infinite, unite and unchanable state. That's why; consciousness never sleeps never changes. -- Walter Russell Always present state

What doesn't make sense to me: So it does appear energy can be created and not destroyed, in fact it appears that from all these perspectives that energy is accelerating in our Universe and in all these other infinite Universes (multiple worlds, bubble universes, membrane universes)? But I thought energy cannot be created nor destroyed per the first law of thermodynamics. It sure seems like a plentitude of overflowing and infinite energies that are not been accounted for with all these physicists.

Thats it, not doing any more dusting or housework be wasting my time !

Go within and you will find!

could we learn to manipulate the expansion of a portion of our pocket with dark energy?

We live because a Black hole 🕳 got a lil to big some other dimension. Waterfall of gravity creating universes at close to infinite rate dropping to a lower and lower energy state in the multiverse. Was what I get out of this lesson today . ❤️

Conformal Cyclical Cosmology. Talk to Roger Penrose.

Will the universe end? I don't think it will, or if so, that another version will be reborn. Time and the universe doesn't begin or end, it just has always been and always will be, in some form or another. Why? Because something exists. And because something does exist, something MUST exist, and nothingness can't exist.

1day of brahma =24 million earthly years 1year of brahma =360 days Life of universe=100 years 24*360*100 million years

Nice to hear Max admit Dark energy isn't very well known, if at all. Great vids!

"there would be infinite new possibilities in an UNENDING COSMOS!!!...even if our little 'pocket universe' dissapears the plentitudes of all reality is literally INFINITE!!!...there would things going on in our universe or at least our multiverse literally FOR EVER in a volume which is literally infinite...even if all things will ultimately end,NEW THINGS WILL ALWAYS BEGIN!!!...the plentitude of all reality is so overwhelming.........."!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.

The universe will never end. It will exist for eternity. Earth however, and humans will fade away. Humans are doing a great job of shortening our existence here.

I think what he's trying to say is that nothingness cannot finish.

I can't sleep because of this show

I sure hope the universe never ends. But it really depends on the likelihood of continued human blithering. If an eternal universe means eternal blithering, I'm against eternality 100%. If we can find a way to stop the blithering...let it ride!

Maybe dark energy has something to do with conciousness and our limited brains can't quite comprehend it. I also question what was before anything that's in our observable universe or even before the existence of anything 🤔

My theory is that black holes drive expansion and the universe is cyclical. That the universe can only expand to the point where all relative motion ceases and everything has a quantum mechanical wave like nature. Then nothing has any definite position and so the universe can no longer be said to be expanding. Size no longer exists so the universe can be either be infinitely big or infinitely small. It doesn't matter because there's no way to measure. Which means that there is a possibility that everything is in the same place at once and no matter how unlikely it becomes a certainty with enough time, not that time or space exists at that point. Everything is everywhere at once. So the universe ends up right where it started in the same conditions it began with. Something interesting to point out is that before one universe came into being all possible universes were equally likely. Every potential universe existed simultaneously. A virtual multiverse.

God damnit. Its been 9 hours and i cant stop watching these. I just thawed out a a ribeye fir two hours, cooked and ate it without turning thisnoff

If all that we see and all that we don't see is expanding into an infinity: one of an infinite possible infinities; all started from a softball sized particle; it baffles me as how there could not be an infinite creator. I don't necessarily beleive in a man (God) in the sky but, it's difficult to fathom a coincidence!

This universe is the perfect Factory for making empty space. The space in this universe has evolved one Universe At A Time. We will figure out how to make a new universe out of the empty space in this universe

Either way, as long as my eternal afterlife goes unaffected, fine with me.

Yes, everything has a beginning, middle, & end. There is a reason for all things. We'll understand it all 1 day. A theory of everything will be the key.

I find it curious that we struggle with accepting the possibility that there could have been nothing instead of something, but we readily accept there being a "future nothing" at the end of the universe...

Don't worry. Be happy. Everything is gonna be alright. Just be calm & carry on. Stop racking ur brain about things u can't change!

The question "Will the universe end?". Can only be asked, from within the belief that it is a 'physical' 'exterior' universe. Which is merely an adopted viewpoint.

This is my favorite RU-vid channel.

23:06: _"And that universe will be full of people"_ -- DAMN! And I who wished this one to be one more than enough!

That Cosmic microwave background beach ball the one guy has is awesome

Can anybody tell what precisely is the main theme music in Closer To Truth series?

There will never be a time where there is nothing. Consciousness will disappear in the universe and therefore there will be no conscious beings who can ponder the existence of anything. All the stars will burn out all the light will fade all the distances will become too great and nothing will ever be perceived again.

I remain restless.

Meanwhile God is smiling and chilling cause he is the only one who knows the truth

If you think about it, you can't really experience "nothing" it's like sleeping, you don't feel those 8+ hours of sleep & darkness. It goes by in a blink of an eye, so you can't really experience eternity.

The theory of that the universe is some kind of simulation is the most interesting and plausible theory.

Everything dies. Even the universe. I say die because I feel anything that has energy and substance is alive indeed.

The moment you die the entire universe ends, whatever you may believe or think is just your imagination while alive.

🎯💯. Meaning, purpose and reality confront the science of doom.... It's like being on death row. Soul destroying unless you believe in something extra, beyond physics.

April 2024 I think univrrse will never end just as it never begun. For me it cannot be otherwise. I admit that it seems absurd but for me a beginning and an end ARE absurd !

… 17:00 … so is the universe, the multiverse a perpetual motion machine?

Depending on what you mean by the universe, of course not or what you have in mind neither is nor can be " the universe"-by definition

Is it 'We do not know and we can never know for certain?' or 'We do not know now and some unexpected future development might possibly enable us to know?'

You cannot end something that never began. Study what the word 'infinite' means...necessarily!

Such heavyweight guests in this episode!

My greatest fear in life to me is infinity. life to me is a abomination, cut throat competition wrapped up in meaningless suffering

Every start = the universe start and every end = the universe end. The many ends (and starts) will go on forever).

WE will NEVER know THE ULTIMATE TRUTH ! thinking about it will just keep us occupied with time which again is an ILLUSION

If the universe ends... what happens afterwards?

Will it be possible for an intelligent form of life to be able to produce their own gravity strong enough to counteract the natural spread of the universe, thus keeping gravity in check?

Stop looking a gift horse in the mouth. Be grateful for the opportunity to have experienced all of this transcendent beauty and awesomeness.

Although it is very interesting question but since we do not know how the universe started surly we can not find how universe ends 😇😇😇

How Can you create this complex World that you see in your own Dreams? IS there a start for it? IS there an end for it?

Deep time is deep to think about

Seems like it's going to take forever for the Universe to end. I think I don't have the patience to wait.

we live in an infinite universe

I believe what we term "supernatural" is simply the outer limit of our testable knowledge, where store our religions and philosophies, resulting in the thought, "I believe". I also believe that that outer limit is eternally elusive, unattainable by the best of human brains. To me there is actually no supernatural. All is natural, just beyond that elusive limit.

None of us get out of this alive!

For the world-inside observer, this world ends with a ‘Big Crunch’. For universe-external observers, the universe is stationary as a quantum entangled state.

The description of the death of the universe sounds very much like the death of anything. Maybe the universe is expanding inside something else. Maybe it's dissolving into it.

After 10^ 10^10 years even protons decays,photons loss its energy due to long travel in empty voids and disappears,dissolves, leading to nothing a cool,bleak, empty,perfect vacuum,but again comes to existence as probably happened,in a cyclic manner, it depends on dark energy value which may probably again takes the universes in to big crunch also. There are three possibilities either big rip, big crunch, or everlasting universe.humans understanding is very much limited.mankind shall not worry due to this large timeline of cosmos, they should worry and protect our earth which is a gift from realty/nature. Goldilocks zone is a gift from almighty energy. So live in harmony and love, as a earthlings. develop from babarinism to humanism .mr.robert is great questioner and ergs for better solutions/answers,fantastic .

There are only two days in your life that aren't 24hrs long. The day you were born & the day you die.

Thank you for yet another challenging video in the series, this one exploring the “end of the universe”, and touching on implications for its meaning or purpose. Another all-star cast of world class scientists is showcased; though of course some have their critics. (Next time perhaps invite Steven Weinberg, Sir Roger Penrose and Sean Carroll.) Now my 2 cents. How will it all end, if at all? Big Chill? Big Crunch? Big Rip? The Penrose Conformal Cyclic Universe? Hindu Oscillating Universe? Turok’s Colliding Branes? Or simply Infinity - a final law of plenitude? Or something else we don’t know? I think some of the answers depend on these questions. 1. Do the mathematical equations underlying Eternal chaotic inflation theory eventually breakdown at some far distant future? Such that inflation is not truly “eternal” but closes. Woody Allen once quipped: Infinity is an awfully long time, especially towards the end. We don’t know how or if mathematics and physics itself change on those kinds of vast time scales. 2. Is the dark energy density, which generates the accelerating expansion of the universe, constant or changing over vast scales of time? (Tegmark’s point). If not, the universe’s expansion can slow or even reverse. 3. Is there more to the known human observable universe than we know? If there is a grander domain of multiple universes often known as the Multiverse, the rules and reality of that cosmic landscape would be unknown and could present a different ultimate conclusion than the one for our local or pocket universe. (Guth’s term). In the face of unknown answers to these questions, my tentative conclusion on the issue of will the universe ever end is this. I take the view that at some far distant future, our local universe will end. Why? I’m guided by the highly-ordered symmetry of our physical universe and human-made affairs (despite its seeming chaotic nature in many other respects). By symmetry, I think of matter/anti-matter; positive energy/dark energy; up/down spin of electron; birth/death; yin/yang; good/evil; right/wrong and so on and on. Beginning - End. Now what about the “ultimate conclusion” to the projected speculative and grander cosmic landscape known as the Multiverse? That is another story for another day. Many thanks again for your video.

Yes

It never began, it'll never end. Just like you're not here right now, so you'll never leave.

Yes.

Maybe Rick and Morty have it right, that there are an infinite number of universes and an infinite number of realities. You just need to open a portal to access them.
