Reputable challenges to The Big Bang are very few and far between, but this is certainly one of them. A genuinely excellent and well constructed presentation that made a strong case for itself. It's perhaps quite humbling to think that in another 100-200 years, the idea of the Big Bang may no longer be the predominant and mainstream scientific view, and if nothing else, that tells me we must always walk the fine line between healthy skepticism and the constant seach for better answers to the biggest questions.

There is a heavy mistake: He first says that 400,000 years after the Big Bang, the first atoms formed (1:36), and then says "even further back", (1:40) the heavy elements were formed. That is a new theory of his own. Big Bang theory doesn't say heavy elements being formed before galaxies. And steady state theories don't propose an "early stage", but an infinite existence. Every paper and article I read agrees that heavier elements than Li are formed at second generation stars, by no means before galaxies and heavier ones at supernovae. Even people who disagree with Big Bang agree that heavier elements are formed in supernovae. Heavy elements being formed BEFORE the light ones is something I don't know from where did he get.

Once physicists realize black holes are creating energy, gravity, matter, space and time they'll have to drop the big bang notion all together. They will have to accept there are black holes, massive ones at that, Gods that can't be observed directly, constantly creating energy, gravity, matter, space and time at the heart of every galaxy. There was not one big bang. There are countless points where creation is a continuous process. That is why galaxies move away from each other. That is why when galaxies are stacked up against one another appear to be moving away at an accelerated pace, some faster than the speed of light. Scientists have skewed many of the facts to keep the act of creation out of their equations.

Paul Steinhardt is one of my favorite contemporary scientists, however... In general, advocates of cosmic inflation speak of "The Big Bang" being when inflation stops. Paul Steinhardt, that I can tell, never addresses this view only mentioning inflation after The Big Bang. Since, he helped formulate early models of cosmic inflation I'm sure he is aware of this. Presumably, this effects his argument (or is only a matter of semantics)? I'm skeptical that he did not mention it, though I may have missed it. I'm also disappointed he did not mention the problem of an early low entropy state that any cyclical model has. Steinhardt, as an early advocate of cosmic inflation, has since come to reject it for three reasons that I see: 1) He despises the possibility that the universe may have had a "beginning" 2) It simply replaces fine-tuning with a even more mind boggling amount of special pleading for inflation to work and 3) Cosmic inflation is non-falsifiable. Regarding #3 Alan Guth appeals to inference to the best explanation to defend cosmic inflation. In essence whether one accepts, or rejects, cosmic inflation the disagreement is largely philosophical, not scientific (depending on one's philosophical demarcation of science!). That is unless we observe the predicted primordial gravitational waves that further advances in detection are making possible to achieve. Also if you're interested, Paul Steinhardt has done amazing work on quasicrystals worthy of a movie as far as I'm concerned. It's a story of another of his crazy, contrarian ideas that has come to fruition including a recent discovery of their formation in the first nuclear test site. He has two similar KZbin talks on them in addition to the book.

You are absolutely mistaking about the Big bang needing to go! Accelerating expansion of the universe is an illusion caused by dark matter neutrinos have been recently discovered to contain Mass light has mass therefore anything that exists within the third dimension or higher contains Mass because you cannot give something volume without giving it weight! Light maintains its speed by slowly dimming out and fading away in space shutting all of its microscopic fractions of a penny weight into the dark matter which absorbs this energy and expands its density creating an illusion of accelerating expansion of the universe and from the singular spot or observation point in space time it is impossible to understand what is happening in places that are unexplored... The dark matter is everywhere it's around our solar system the more our sun lets out energy the more it increases its density just as it is in every single star around every solar system and our entire galaxy and every galaxy in the entire universe! This was the reason why I started my channel and some of the first content that I made! I'm telling you that that you are absolutely wrong accelerating expansion is wrong it is an illusion caused by exponential growth of dark matter AKA dark energy... A dark matter particle does not exist because it is not composed of the fundamental building blocks that make up you and me and therefore we cannot view it in these bodies it is not composed of strings... It is hooks, Because of this we cannot view a dark matter particle and we will never find one. We are treating this accelerating expansion like it is royalty amongst the scientific community when it is a relatively newly learned thing that no one has been able to figure out well I have figured it out! My system brings together everything it also belittles are measurement measurement systems but these are the facts and we must go forth with the facts not Bullshit just to maintain the status quo!

In order to change this you need to come up with a lable or acronym that is just as simple ,discriptive,and memorable.

It is also hard to believe that no-one may have any motives beyond pure scientific inquiry to argue for such theories, when they happen to align so comfortably with many already widely and historically very popular religious ideas. That is simply true, whether or not anyone feels comfortable including it in any given conversation on these topics.

Wouldn't we need to have a slow contraction first, then somehow have the contraction reverse to become expansion later on? this is very confusing to me. there may be an explanation here, but doesn't the gentle contraction idea still need to explain inflation - just a different type?

all these explanations like the one given here aren't really descriptions of the external world....they are instead descriptions of the consistency of symbolic mathematical 'logic' that is happening inside the human brain, consistent with whatever 'sophistication' the mathematics of today (or yesterday or tomorrow) represents. When Euclid of ancient Greece was the standard of sophistication of the mathematics of that era the geometric sphere was the accepted description of the fundamental nature of the universe and the stars were oil lamps hung on the celestial sphere using special hooks of some olympian kind......later, the standard description of the universe made it 'obvious' that the earth was at the center of the universe and the earth was that around which everything else moved in concentric circles nested inside each other.....today we have the epsilon factor and dark matter and the argument about expansion and contraction that is said to be 'observable' and 'based on evidence' of things like the doppler effect.....in the medium term future all these present day concepts will be discarded as an unrevealing series of dead ends and replaced by newer mathematics and newer assumptions which will, in their turn, claim to be describing the external world while in fact they will be merely describing the internal necessarily defective mathematical logic of an even more sophisticated set of number theory concepts linked by another idea and piled one on top of another into a huge edifice of symbols that then require a chief priest resembling a new Paul Steinhardt to interpret to us........all these explanations about inflation and bangs and energy resemble a parable, any parable, spoken by Christ in the New Testament of the bible...the parable is just a fairytale geared to an illiterate 7 year old mind and its up to the various subsequent clergymen to attach whatever concrete meaning they think it means and give that to the congregation. Thus Mr. Steinhardt addresses the scientifically illiterate minds of modern men with his interpretation of symbolic mathematical parables called equations, all generated by talented storytellers and bearing quite elegant but completely unprovable unverifiable relationships to the conclusions they purport to render. Nobody knows the true nature of the universe or where it came from or where it will go, but you never hear a physicist make statements of that kind.

I'd welcome some input on this comment: If we want to understand the state of the universe now we should be looking at what is happening in our "immediate" vicinity. If we want to understand what happened a long time ago, we would be looking at signals from the era we are interested in. So to deduce what the universe is doing now, examining signals from the era of the postulated big bang would be invalid. ? And a further thought: if the light reaching us is postulated to have been traveling for 14 billion years (give or take), where are the objects that emitted that light now i.e. how "distant" would they be now (according to our local time)?

Okay, I dosed off and will have to watch it all again. It’s well done. Not your fault. Just a careless meditation sleep-drift into parallel time line. Here’s the thing. I am more inclined to rely on the answers derived from listening to my favorite channelers and mystics. Hold on, hear me out. A valid dimension is the spiritual dimension. I follow a half dozen brilliant channelers. I look for patterns where they seem to all be saying the same thing and what they channel aligns with my own intuition. They have as a group answered some scientific questions. I must say they seem to all say that the Big Bang is a nonevent in an infinite universe which does not have a beginning. They all say the problem to understanding is the human confusion with the concept of time. I’m typing as I listen and you are now hitting on quantum gravity. We each create our own timeline. You are on your time line, I am on mine. What’s more, it is thereby possible to create your own future by reimagining past events as happening differently. Start with the meditation “I am!” If you drift off that thought, come back to it. Just “I am!” Do that for a few moments, then allow yourself to reimagine a past event that you want to change and create a new now. This works in the relationships between people. There are other directions to go with this including traveling by changing your consciousness. Summarizing: (1) our universe is consciousness, (2) Everything turns…everything. (3) Turning is required for consciousness to occur. (4) All things, right down to every cell in your body has consciousness and emotions. (5) Changing your level of consciousness will lead you to know “I am.” If you want to know if the universe is flat or curved listen closely to the responses to the question posed to your favorite channelers…. It’s becoming the thing to do again.

I want to know what Steinhardt's students' models show for a single universe horizon, is it _locally_ smooth and flat? It should be so otherwise it's inconsistent with empirical reality. But then that means "big bang inflation" is explicable not as an exact description, but only as a local approximation (and the inflaton field is spurious, a fiction? a result of not using the complete picture). I think Lenny Susskind would say something along the same lines.

The fact that one of these ideas also has been the idea of the religious of this world, the idea that the world is created, is for me very suspect. The creation idea is common for many religions, and Big Bang Theory (BBT) has inherited this idea from the Christian religion. That inheritance adds to the scientific difficulty of the BBT; the theory that fitted the religious ideas so well has only found difficulties in the scientific world. So, give up this poorly analyzed idea that the world is created, everything is, by the way, consistent with the idea that the world exists without limits in time and space. The BBT has a crippling effect on the scientific thinking, let me exemplify. When facts about the rotation of the spiral galaxies became known, the immediate reaction was that there was something wrong with our conception of the universe, something strange must be present, like dark matter or MOND or something.. The thought, that our theory about how the spiral galaxies functions was wrong, never appeared, because that could have destroyed the BBT theory. Today we know, because irrefutable scientific research shows that our own galaxy is expanding. That fact is not discussed at all, because such a discussion will add to the scientific difficulties the BBT already has.

So - rather than an infinite multiverse we may have infinite universes going back in time. In each case, I believe, each universe may have different physical constants, so some will be capable of supporting life. Either way as far as I can see is a totality where everything that is possible must occur and indeed likely repeats infinitely. This resembles the concept of quantum immortality.

Recombination- the orange glowing hydrogen plasma cooled down enough for the electrons and protons to pair up making hydrogen gas, which is transparent to light (except at a few wavelengths). That’s what the cosmic microwave background is. It’s the time when space becomes transparent rather than being a glowing fog that you can’t see through. Either that, or by first “atoms” they are referring to the first twenty minutes after inflation or the singularity or whatever, when everywhere in the universe was as hot and dense as the core of the sun, and (ionized) hydrogen (that is, a bunch of individual protons and electrons hanging out in the same area, but not bound together in any way) was hot and dense enough to undergo nuclear fusion into helium (nuclei) and even some lithium.... which only happened for just under about twenty minutes. After that, it was to cold for fusion to happen any more (until stars form millions of years later). We know that this only happened for a few minutes because the ratios of hydrogen, helium and lithium in the universe are exactly what you get if you do fusion for about twenty minutes and no longer. (Because the lithium gets broken down by more fusion... so it had to be short... and it’s not long enough to make carbon.)

I wonder if there might be another way to view all of this. Say a universe of infinite age, where galaxies are always recycling material that ends up re-emitted and somehow taken up to form new matter. Maybe the emission of neutrinos from black holes/plasmoids followed by neutrino capture in cosmic objects? I don't have anywhere near the expertise in math to be able to render a hypothesis like this mathematically.

Your logic in believing over simplified version is interesting. Years ago the simple idea that earth was the centre and the sun revolved around ot. Even simpler is the flat earth. Take your pick. The problem with big bang is simply it is not feasible and does not explain what's outside the visible universe. In a side note that diagram they project of the evolution of the universe is only a projection as we are not able to, not will ever be able to, see the universe in real time. We not even sure what is happening to those galaxies that we are observing now as they were ages ago.

The problem with the BBT is that it is just that...theory. It can therefore never be proven. Another problem is that it is treated as scientific canon. The universe exploded out of nothing into everything at no time, at no place and for no reason. What is the basic difference in believing that and believing in magic?

@deandeann1541 2 жыл бұрын

The difference is that the BBT is a result of following known physical laws backwards in time. The problem is at the extreme conditions of a big bang it is not known what laws will apply in the form known today. The magic is not in the known laws - it is in the unknown laws.

30:32 Steinhardt literally says: "... it's important that when we finally get to the slow contraction phase, that the slow contraction is very fast." WTF!? Then why does he call it "slow contraction" and not 'very fast contraction'? I'm lost ... or could it be that his explanation of this 'theory', or even the 'theory' itself, is flawed? By the way, the notion of a cyclical universe infinitely going through phases of contraction alternating with phases of expansion is far from novel. Einstein considered it in the 1920s.

Talking about beginning first thing every one needs to know that initially NOTHINGNESS exsisted. Though dimensions of nothingness did had certain properties and characterstics. When there was no substantial exsistense of elements only thing which exsisted with nothingness was SOUND. Waves of SOUND is what which had given birth to formations of different sort and phenomenon of action & reaction started.
