In 2023, a team of researchers proposed that our universe experienced not one, but TWO Big Bangs about a month apart from one another. The first for the stuff described by our Standard Model of Particle Physics. And the second for that ever elusive Dark Matter and all the particles associated with it.

It will hopefully have moved on from such stupidity. The big bang expanding universe doesn't work with the Hubble constant unless we are the center of the universe. A second inflation would wipe out the first so even more stupid. The simplest solution is that light slows down because space is not empty. And as we know light slows down In matter. Refraction. And since the redshift is explained by light slowing approximately 4.6mm/a/year, we wouldn't be able to measure it on earth. But can see it in the stars as the light travels millions or billions of years. So no need for dark energy explaining expansion faster than C even though the theory says nothing can go faster than C. The gravitational lensing and squeezing of spectrum from distant galaxies tells us the journey that light went on to get to us. Not as Hubble constant says as a result of our observation. How would our observation affect galactic movement a billion years before we exist?
So let's realise the outer edges of the galaxies spin faster as it is smaller bits. No need for magic dark matter that exists everywhere except anywhere we can test. But causes gravity, which we can detect.
Join the dark side of academia!
Im a chemist, so i think about it from that pov. Quantum chemistry, interplanetary chemistry and physics. Omg why were we born now lol, but its funny to say cause then we’d just ask to see the next hundred years😅

Are you going through perimenopause, too?! Because I am and this statement is a perfect description. 🎯
If Derek Zoolander was slightly self aware this is something he would say lol
So do I, but my local KFC is shut right now...
At least you're hot, I'm over here just being dense.
"Unthinkably dense ball of matter" also describes the youngest of our cats.
"The Primeval Atom" is such a badass name and i'm very sad it did not catch on
New children of atom (fallout 4) playthrough is a go. Gonna play as a super mutant going by that name
yeah it sounds so much cooler than singularity does
however it's inaccurate as an atom must have a nucleus and an electron shell
What if dark matter came before regular matter? I assume someone has already thought of that and ruled it out, but I would love to know the reason why.
My guess is computer models. Stick in your proposed initial conditions and then run it forward to see the results. If the results don't match the reality that we see then you can rule out those conditions with that model. So the people investigating this idea found that they can get "our universe" when the dark bang happens second but not when it happens first.
That's all just a guess on my part though.
Guess here, but since after their creation there was way more dark matter, my guess is that if it was made first the gravitational pull by it would have been too great for the matter coming afterwards to expand properly
Good one, i would even go as far that dark matter could be a parallel multiverse, mostly interacting by gravity, in the darkverse our universe would be perceived as darkmatter
I like to play with that idea, too. Just imagining that it’s just a regular universe like ours existing in the same space but our and the other matter just cant interact with each other. Maybe it’s a missing quark or a different higgs boson tying them to another “frequency” or whatever.
We theorize the existence of Dark Matter due to the gravity we observe. There's no guarantee that its actual "matter" and not something else that also produces gravity.
It's entirely possible that energy or particles which *could* travel faster than light existed during the early universe and then decayed into other particles during the first instants of universal expansion.
Or maybe Supernova rules apply and the only "stuff" left in the universe is what can be contained by the binding energy of the fundamental forces.
My favourite tinfoil hat idea is that the universe is expanding as it cools and "dark energy" is something more akin to Hawking radiation.
Thankyouthankyouthankyou for using "hypothetically" instead of "theoretically". This is a science channel after all.
It is my suspicion that in the early universe, the asymmetric process that favored the creation of matter over anti-matter had some intermediate particles. A phase change occurred as the universe expanded and cooled, and the process that had the matter / anti-matter creation asymmetry could no longer be supported. Intermediate products got trapped. They are unable to decay or change into other particles because the current vacuum phase no longer supports the interactions in which these intermediate particles participated. These leftover particles are the dark matter (WIMPs) we've been looking for.
That's cool. Kind of like how different minerals/rocks form?
They couldn't have come up with a more evocative name for it than the "dark big bang?" I propose the "horrendous space kablooie" instead.
I propose calling it "the Noodle Incident."

I'm used to hearing cosmology talked about on time scales of fractions of a second and millions of years. For some reason it feels really weird to hear something cosmological talked about as happening about a month after the big bang.
Also, is there something that rules out the dark big bang coming first? Or is that another possibility?

Perhaps the Dark-Big-Bang happened before the Visible-Big-Bang?
An initial thought of mine would be that it would HAVE to. (Because of the uniformity and the necessity for everything that uniform to have to have been close enough.)

Nope, it could not have happened in a universe that did not exist yet.
@@nicholasheimann4629 , but why couldn’t the beginning of the universe have been one of dark matter? Or why would observable matter have needed to exist first before dark matter?
@@nicholasheimann4629 We don't know how large the universe was at the so called big bang, so in some sense the universe could very well have existed long before theorized inflation :)

Imagine if fate of the universe is the cosmic equivalent of turning right so hard you go left and end up right back where you started.
i think the very fact that the universe is so specifically hospitable for life, with just the right laws of reality and physics, is evidence enough for some form of the "big crunch" theory.
@@wyattmurphy7153 idk fan "specifically hospitable for life"
seems a liiiiitle bit of a strech
since we only know of 1 (one) blue pale dot innit inhabited by life
and everything else (as far as we know it currently) is completely sterile/ devoid of said life
it has life, yes
that doesn't mean in the slightest it is "specifically hospitable for life"
we could just be a blip in the grand scheme of things, a fluke
a slight blink that happens not that often
This is the second science channel to discuss this in the last few days. The other covers new papers, but this one talks of a 2023 study. So, did the study get first published in 2023, but only recently pass peer review? I think I need more coffee before I look for the bread crumbs for this mystery. 😂
2:15 I would like to say we actually have a word for a singularity of infinite density, it's typically called a black hole with its event horizon being the gravitational influence of that point
it's wild how much we just assume dark matter is the correct explanation of the data and not that our understanding of gravity is incomplete. neither idea has enough evidence to be anything but conjecture
Every sci show video I expect to learn something new, and every time I do, but it always leaves me with more questions than I'm use to
There's actually a different second big bang but it never got localized because they thought it'd be too hard for western audiences
Huh?
@@officialgreenhero1435i'd guess the guy was joking about how some films have sequels that never gets distributed/ localized in the west cause of audience lack of interest or as op said it's too hard
"yes we had one big bang, but what about the second big bang?" 😂
Young sheldon is technically a prequel but I still propose it as a name

I'm still not convinced there was just ONE SINGULAR event of a big bang, but rather a collection of creation clusters. That goes for light AND dark matter.

What is the possibility that the reason we see particles pop in and out of existence and gravity is so weak is that they exist on a higher dimension? I watched some videos on higher dimensions and it's really hard to comprehend, but one explained with a wall, we cannot see behind it, but a 4D creature would be able to. Also, it would be possible for 4D objects to come in and out of existence, in our 3D plane of existence. If any of that is true, then the big bang was a funneling of matter into our 3D plane of existence, sort of like spilling water over a 2D plane. The only way I can comprehend it is that a bunch of matter collected in the 4D plane, a portion bled into our 3D plane, but still linked to the 4D and it is spreading over the 4D plane creating the stretching effect of the universe.
We are 4D though
Great Script! Flawless really. Kudos!

I enjoyed that. Very interesting! There’s so much about the universe we have yet to learn. I believe that what we think of as supernatural events are just events we don’t understand yet in the realm of cosmology and science.

Big bang 2: 2 big 2 bang
We've got the obvious "Big Bang: The Dark World" and "Big Bang Into Darkness, but I like "Big Bang XXL".
the real question is, can i turn myself into dark matter and then phase through walls like a cartoon supervillain
Quarknugget sounds like a good child friendly insult
2 bang or not 2 bang. That is the question.
Dang! A Double Banger!
One question about dark matter: while we can't see it, would we ("we" as in "us, humans") be able to physically feel it? Would we be able to touch it with the tip of our fingers, or feel its weight in the palm of our hand, even though we wouldn't be able to perceive anything with our eyes?
Maybe it appears as nothingness, or void. It's so outside of what we were evolved to perceive.
Lol maybe there's aliens that acquired fitness traits to perceive it to survive
No and no. If the cold DM model, the one that's most widely accepted, is true, DM doesn't interact with "normal" matter and possibly very weakly with itself, except by gravity. "Cold" means that its particles are slow, in the same sense as molecules of cold gas are slow, which means low average kinetic energy, i.e. low temperature. Humans are made of regular matter, so DM particles (WIMPs in CDM) just pass through you without any particle interaction. If you weigh, say, 50 kg as a random round number, there should be 4 times more, or 200 kg worth of DM present inside you at any moment. But since it's spread evenly through all space around you (or, speaking of the scale, even around the Solar System), its gravitational effects cancel out because it's all symmetric-there's as much of it in any direction from you as in any other. The symmetry is broken only at a galaxy scale, as galaxies in the CDM model are surrounded by a spherical cloud of DM, called "halo", larger than the galaxy but at least of the same order of magnitude in size, so there should be a stronger gravitation pull from DM on a star at the galaxy's periphery in some directions than in others. Again, that's all true _only if_ the CDM model is true. CDM explains a lot of observation, but until we detect the elusive particle (and, as a golden standard, in two different ways: recall the detection of faster-than-light neutrinos finally traced down to a single damaged cable connecting two pieces of equipment), it will remain a hypothetical working model.
It's always fine to say, "we don't know". On the opposite, had we known everything, _that_ would be ultimately boring!
I'm surprised no one has gone the Cards Against Humanity route:
Big Bang 2: Bigger Blacker Bang
Badda Big, Badda Bang!
Umbral expansion sounds pretty cool, although you can argue that’s misleading given there aren’t any moons involved (probably)
Wanna get existential? If the whole universe existed in the singularity, how can we know we're not in the singularity still?
I'm really curious why every description of dark matter (at least on TH-cam!) always seems to presume that dark matter is within our universe. But what if the reason we can't detect anything other than its gravity is because it's in an adjacent universe?
When you say other universe are you talking about A. a part of existence that we don't directly interact with, B. Many worlds theory, or C. Something else entirely?
@@danielsayre3385 Pretty much many words without the "many" - only requires the presumption of one additional parallel universe adjacent to ours.
As just one reason of many, because of galaxy rotation. Gravitation is local, so whatever gravitates has to be in almost every galaxy. Oh, and we have no evidence for "adjacent universes". In science, we don't postulate something unobservable even in principle as an explanation for something we don't understand.
@@cykkm You mean like ... dark matter?
@@morrowdoug I don't, and DM is not unobservable _in principle._ It may not be observable directly, but so are the Higgs boson or quarks. Come think of it, even the electron: you can observe Compton scattering of light, for example, in support for the electron existence, but the theory has to be supported by other, possibly as indirect observations. We have observations such as the Bullet cluster, just not yet enough for a solid support of CDM vs some alternatives. We'll be there eventually. 100 years ago we were in the same shoes w.r.t. the neutron. Or galaxies outside of the Milky Way. We also didn't have TH-cam full of smart asses back then.
If I'm understanding it correctly, its like a dark matter vacuum decay?

Not surprising that current laws of physics break down if you wind back the clock as the laws of physics evolved from the beginning and were probably far more primordial to allow for the singularity. It’s like applying current auto mobile traffic laws to the amoeba’s of millions of years ago😆
That actually might be truer than we realise..
I wouldnt be surprised if big bangs are just another periodic cosmological just measured on a huge time scale.
