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.

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?
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.
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?

Nope, it could not have happened in a universe that did not exist yet.

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. 😂
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.

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
Big bang 2: 2 big 2 bang
"yes we had one big bang, but what about the second big bang?" 😂
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
Great Script! Flawless really. Kudos!
Whoever came up with the WIMPs acronym should get the Nobel prize
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.
Dark particles the size of ten trillion protons would be quite hilarious in hindsight; we could literally be inside of one and not know any better. 😂
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!

The reason it breaks before it gets there is because you're rewinding to the wrong point. It's not that there was an infinitely dense point it's that all of space ripped apart everywhere all at once. Creating an explosion that was so powerful that it was able to turn pure energy into knotted up energy AKA matter. It's a crustacean breaking its shell so that it can grow larger. The number of numbers between 0 and 1 is infinite however the number of numbers between 0 and 1 googolplex is infinitely larger.
Umbral expansion sounds pretty cool, although you can argue that’s misleading given there aren’t any moons involved (probably)

I'm really curious why every description of dark matter (at least on RUclips!) 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 RUclips full of smart asses back then.
I like the idea of the "missing hand" of the nuetrino as a good candidate to start understanding Dark Matter, if it exists or not. Could be we just do not understand galactic scale gravity.
Maybe the second Big bang is still happening and that's why the universe is expanding more quickly for some reason either time is different for dark matter and dark energy or the explosion is just really slow.
From my understanding the universe itself *is* the big bang, or more accurately the sudden spreading and thinning out of space-time and all the stuff inside it. If there was a second one, wouldn't that spawn its own universe independently from our own and be irrelevant to our own reality?
This also compounds my confusion about *where* this second big bang occurred. Did it just happen simultaneously across the entire (at that point very non-singularity sized) universe? And where could it be located prior to that event?
(Powers up to the max) Hero: You won't survive this one! DARK BIG BANG!
Spider Robinson used the possibility that our universe exists in a false vacuum threatened by human activity as the McGuffin of his delightful novel “Callahan’s Key.”
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..
Thank you! I am glad someone reads my stuff.
If our suspicions that all we can observe is about 5% of all stuff, isn't it a bit arrogant to keep thinking that what we call matter was the beginning of creation? It should follow common sense that there was a preexisting condition of some kind where dark mattter and/or dark energy were here before what we call big bang. That would explain why visible matter and energy are so small part of everything, cause it's a new state of affairs, maybe increasing it's participation. It would also be more probable that our big bang happened because of a change in the dark matter that was there already, removing the unexplainable of getting something from nothing. Someone could claim that it would be just moving the line down the road, but it is not the same, we have many indications (if not proofs) that known matter wasn't always here but we can't say the same about dark matter since we know next to nothing about it.
I'm surprised no one has gone the Cards Against Humanity route:

If Dark Matter causes bends in light then one can assume dark matter has mass and if it has mass and dark matter is 95% of the universe then dark matter must be all around us here on Earth (if it is not then why) or all around the ISS. Anyway if it is all around us or around the ISS and dark matter has mass then why are we can able to feel its presence? I mean, an object with mass, when it strikes our bodies is felt, isn't it?

This might be a dumb question, but I've often wondered if it's possible that dark energy at least could just be regular energy that's been read shifted long enough that it's wavelengths are longer than the speed of light with enough time since the beginning of the universe. Like, wouldn't that make it undetectable but just as much real energy in the universe

Big Bang 2: Revenge of the Bang
Just to point out phase transition is "known in physics", not chemistry. Chemistry deals with loss and gain of "outer" electrons, or sharing and unsharing of them. None of such happens during phase transition. (I mean, chemistry pays close attention to phase transitions. But phase transition is a physics process.)
Big Bang 2: The Universe Strikes Back
Neutrinos don't emit, absorb, nor reflect light -- they are completely dark, and have mass. And we can create and detect these dark matter particles. It's just that we're also looking for a different dark matter particle, besides neutrinos.
Just the concept of dark radiation seems incredibly counterintuitive.
"2 Big 2 Bang" and yes there is a 1999 Skyline and a 1970 Challenger somewhere in there.
Wanna get existential? If the whole universe existed in the singularity, how can we know we're not in the singularity still?
Dark Matter could've existed during the Singularity. Big Bang could've mixed it all up.
After all. The opposite of a big bang is a big crunch. The Big rip is an extreme consequence of the Big Bang. The Big freedia could be a prequel of the Big rip.
Big Bang 2: On Banger Tides
Imagine our universe is a black hole inside of another parent universe. Now think about what happens to black holes in our universe. First, when they come into existence it is like an explosion that creates a boundary. And when more stuff falls past that boundary it expands. Notice it expands at variable rates depending on how much stuff is falling into it. And something happens to the stuff as it passes through the boundary to transform it into energy which then condenses back into matter inside. The stuff falling through has the appearance to us on the inside as dark matter. We're seeing it's gravitational effects, but the stuff isn't here yet. It can take a while. Time is weird. And sometimes black holes will collide. We see that inside as like bubbles next to each other. Like the one we are in could have collided with one that was much older or younger (in the parent universe) and that's why we are seeing stuff that doesn't fit our model of one big bang.
