    Quick audio tip : Try to set your voice volume around -6db to -3db before the export. Louder vocals is better for these type of videos. It's good for audience retention.

    Just as a minor note: I remember "Big Bang or Big Bounce" being debated in the 1960's! What's old is new again! 😀 (mind you, I was in junior high school at the time, so I don't remember the details. Just that there *was* a debate going on...)

      @stevelenores5637 3 ปีที่แล้ว +5

      @@andykeating791 Well let's go back to the title. It is not a new model, just a refined one. The bounce theory goes back to the beginning of big bang theory at least 60 years ago. The biggest problem is that each bounce increases entropy. The expansion of the universe assumes entropy also increases and is in one direction overall (when order is imposed it has an entropy cost someplace else). Go back in time and entropy approaches a vanishing point. Bounce theory can't explain that.
      Another big thorn in bounce is the accelerating universe. Even if true we have seen the last bounce.

      @MarsStarcruiser 3 ปีที่แล้ว +1

      Not Quite 🤔… In my own personal opinion skip “big bang,” since we just know of CMBR formation 380 thousand years after…but not necessarily before
      Also after blackholes would go > blackhole consolidation > more super massive black holes form and existing smb’s grow> cmbr temperature decrease > hawking radiation evaporates small blackholes but not larger ones fast enough > cmbr reaches lower than super massive blackhole temperatures > smb inflow becomes outflow > white-holes chain reaction rips apart space-time > cosmic balloon deflation > entropy spikes > saturation settles >…cooling > protons and electrons reform…cycle continues…
      Big bang singularity seems too isotropic for what we’re seeing, but a white-hole-fountain “chain big-bang” might be a more plausible solution to address the irregularities within CMBR and the Dark Flow, and many of the missing pieces from the current model.
      Don’t know for sure, actually looking right now to see if someone already math’ed this out in a refined theory, or even if such notion has already long passed debunked by now. Would like too learn more🤔

  • @Ungtartog
    @Ungtartog 3 ปีที่แล้ว +2

    I think the big bang is like a point on the horizon where two railroad tracks converge. It only looks like a singularity from our vantage. If you were to move closer to it by moving backwards in time, you could never actually reach it, any more than you can reach the place where the two rails converge.. because they never actually do. As you get closer to what you think is the beginning, increments of time and space shrink, but they maintain their scalar relationship to the observer. The observer is not aware that their seconds and lengths are getting shorter as they move backwards in time. From their vantage nothing changes. This is similar to Penrose's CCC but without the necessity for a badly explained transition into a "new" universe. No collapse, no new funnel. Its the same universe it has always been and always will be. The scaling part is on point tho. The absence of detail of what happened at the earliest moments and exactly what it looked like, so to speak, is limited, literally, by our size and the the distance between us in both time and space to the thing we are attempting to understand and observe. If we were able to scale ourselves down to the correct relationship in that "hot dense state", we would have a lot of questions answered, but I expect "the begnning" will be just as far away as it ever was. That fraction of a planck second will now seem like billions of years. True singularities are not actually possible any where but the imagination.

    • @thethirdchimpanzee
      @thethirdchimpanzee 3 ปีที่แล้ว

      I have seen models of the Big Bang, or begining of the Universe, that is like a funnel...until it gets near the begining and instead of collapsing to a point at the bottom of a cone, it rounds off and...I am not sure what that means, except it's...I dunno, I think, the space dimension becomes a time dimension and the time dimension..and there is no singularity.

  • @wulphstein
    @wulphstein 3 ปีที่แล้ว +1

    I had postulated the existence of an "expanding" graviton. The expanding graviton is (1) the carrier of the physics constants, (2) the wave function psi (or more accurately, what wave functions are made of) and (3) expanding gravitons behave like water ripples that expand from a point into a 3D+1 sphere, at the speed of light, with a radius r = ct. If expanding gravitons exist, then EVERYTHING in experimental physics can be accounted for including quantum mechanics, relativity, quantum field theory and the standard model. The surface area of an expanding graviton is a virtual photon (or a real photon). The big bang began as a single graviton (with the outer surface of a photon) with energy equal to E = hf = energy of the big bang. New gravitons are constantly being created by either events or conditions of the previous state of the universe. The inflationary epoch of the big bang is caused by the extreme temperature/energy conditions created new gravitons at an accelerated pace. Inflatons are not necessary.

    As we start to understand that the number of black holes is greater than we thought, we approach an answer to the "horizon problem." Black holes absorb light. The more black holes, the less of an issue the horizon problem becomes. Apparently all black holes are not merely centerpieces to galaxies.

    When it comes to your question - I am not qualified to have even an opinion. But it sounds plausible with this alternative approach. Albeit the problem of how it originally all started, seems to be unsolved. Or?

    TWO QUESTIONS:
    1. Are there an infinite number of contractions and bounces? I thought it has been determined that “bouncing models” can not be past eternal?
    2. Would that mean that the assertions that the universe continues to expand and that there is insufficient mass or gravitational force to cause any future contraction is false?

    Would not each cycle in a bouncing universe lose some energy, eventually ceasing to bounce at all?
    Also, what if there was not just one big bang but a huge number at once (or nearly at at the same time). For example, if the initial "bang" was more of a separation than a bang. That is to say parts of the initial matter/energy bundle broke up into smaller parts of that initial whatever it was, speeding away from each other in all directions like shrapnel from a bomb. These portions travel for some distance before exploding into more yet smaller units, and so on. Then they all finally explode a final time into the primordial soup of the initial universe. So the matter/energy are already "expanded" before any big bang. No expansion in pico-seconds needed. Of course this requires something outside of our universe. The mini big bangs may have gone off like a fission reaction with one triggering another in a geometric progression. Those explosions could have taken place much faster than might be thought since the speed of light may not have been a barrier to matter or radiation at that time. Could also be that those big bang mini-bundles exist in great numbers in whatever lies outside our universe. Every now and then one explodes (or something else explodes) setting off a chain reaction at FTL rates and seeding another universe.

    7:45 ~ 8:00 Quantum runaway. I'm not terribly keen to 'explain' that one because I think it's fact.
    Within our own universe, we have the 3rd law of thermodynamics. Energy maybe equals mass but energy is neither created nor destroyed. It can and does get altered and converted between forms, but nobody creates or destroys energy.
    I think when you start talking a multiverse and black holes that form a singularity at the centre, and the neutron-star mess gets forced onto the singularity like toothpaste, what happens is some of these sources of energy disappear, like quantum virtual particles, and others find a confluence of spatial and temporal dimensions, a potential universe, and they pop out there. There are some very big imbalances in this idea. There are many cases where large amounts of stuff & energy goes down a hole and vanishes, and there are other cases where you put 5 units of mass through a small hole, and you get 5 million units of mass come out of that hole. I think if you look at this on too small a scale, you see conflict with the conservation of energy, but if you expand your view to the largest scale, it all roughly works. I can't calculate that down to one decimal place but my intuition says on the largest & most inclusive scale, as long as you blur your sight a little, conservation of energy does work. My point ~ you don't need to 'avoid' quantum run-away to do that. Quantum Runaway is simply part of the explanation, much the way 'inflation' is part of our current explanation / standard model.

It would be like having two or more contraction wedges at once at separate places in the Universe, like arms or limbs. Thanks again for explaining this Big Bounce model.

    what i like about penrose idea is that at the end if we only have photons then however "big" the universe might expnad to, it's "size" is irrelevant and could be taken as zero again. you could say that the initial singularity of the big bang was infinitly large to begin with, we might picture a "singularity" as being infinitly small, but there is no reason it couldn'r be infinitely large, if it's the next aeon in the cycle (which in fact is the first, and only aeon, as time starts "now").

      I don't think it has to contract or bounce as such, spacetime simply decays in context of accelerating expansion and a big rip. At that point there is no material universe left, just a thin soup of energy dominated by dark energy. The rip leads to an inflationary effect with a proliferation of virtual particles that separate before they can annihilate, presto bigbang. The whole cycle akin to a relaxation oscillator but with no net energy gain or loss. How's that!!

    This model has the same problem as the big bang with all the matter/energy in a small volume. Gravity should have won and everything would have collapse into gigantic black hole!

The another view is our universe is the inside of a black hole and from the start matter is drawn to the to the black holes sphere giving us inflation and a hot start

    What if you can explain the big bang and expansion of the universe by assuming that spacetime is made of "expanding gravitons ". Expanding gravitons are continually created. They expand at the speed of light and overlap with other gravitons to create spacetime. Whatever the usual rate of creation of gravitons, the inflationary epoch can be explained by a surge in the number of gravitons that were created.

    The Universe isn't expanding, it is always bouncing at points. Galaxies are the deflation points which move apart due to that deflation point. Gravity moves towards points, but at the same time divides boundaries, and parts in the middle.

    Question from a complete laymen:
    Does this theory imply that entropy will cause our universe to reach a point at which there is no more possible interaction between energy states?
    If so, could it be that this leads to a sudden *decrease* in entropy, ultimately resulting in an increasingly *deflating* universe, triggering another sudden inflation, et cetera?
    Perhaps someone more literate than I can reflect on this (preferably in laymen speech) ;)

    So what if you didn't say or I misses that gets the previous contracting phase going? I vaguely get how cyclical conformal works but I'm not confident I could explain it to someone? Edit, erase, erase. What I wrote after this doesn't make sense? So let me rethink that.
    Well upon review, no I didn't miss something, that is you'd did say how the contraction gets going, nor did I see it in just glancing at the paper either? I can't be like as I originally was going to speculate the cyclic conformal theory, that wouldn't make sense because it requires ever expansion in order to finally lose hold of its 3rd dimension!

No good reason to support it other than random periods of acceleration certainly does not lose what we have observed. Did you refer to Neil Turok at all?

      @@glennpearson9348 To make my point more clear... if you have a piece of elastic with evenly spaced dots on it, and then stretch it at a steady rate, say 1mph.. the 1mph rate will only be what is apparent as the velocity of the closest dots to you.. but the dot beyond that is moving away from the dot closest to you at 1mph as well, so it appears to be moving at 2mph, even thought there is no change to the velocity of the stretch.. only APPARENT velocity from your own vantage. This makes it difficult to determine if the universe is actually expanding at an ever increasing rate, or its actually a steady rate that just looks like its accelerating via the aformentioned principal. I did have a cosmologist explain it to me once, and there are 3 data streams that support acceleration, but I'd have to go look it up to remember what they were. Red shift alone won't do the trick.

      @@Ungtartog Interesting theory. So, it sounds like the line of questioning here is whether spacetime "stretches" according to some "spring constant," the way a spring or a rubber band does. It is curious to me that some have calculated the size of the observable universe at 93 billion light-years across, yet our best estimate for its age is only 13.8 billion years.
      If we begin with the notion that the universe began with a singularity that expanded, and we assume that the speed of light were as insurmountable then as it is today, then the universe would only be about 28 billion light-years across (give or take).
      Even if we begin with the notion that our universe was born through an extreme spacetime constriction, and the same assumptions about the speed of light, then we arrive at the same conundrum.
      Fascinating.

    None of these models ever explain the absurd young age of the universe. The universe isn’t even one billionth its potential age according to most models. The reality: at 13.8 billion years, the universe is likely at least 10% of his potential age. Actually odds are it’s at 50% of its potential age. In contrast the heat death of the universe is measured in years with a Google of zeros. Cosmology is completely off the tracks when it comes to measuring either the current age of the universe or predicting the potential age of the universe. It’s baffling that cosmologists never address this issue.

    I have got something for you brain Keating . Let go , the observable universe started with all the matter spread fairly evenly across it , then the matter starts to clump (gravitate) together all at the same time. The matter slowly accelerates outwards towards some really dense matter surrounding us , like water vapor in a bubble . You might be saying I'm breaking the speed of light , because I did. The light speed limit is a mathematical concept so I largely just ingnore it. When you divid by zero you know your answer is wrong but apparently Einstein didn't think so , not my problem though.
