What if There is a Dark Mirror Universe All Around Us? With Prof. David Curtin

Is there a dark matter mirror universe? If so, there is a way to look for evidence of it's existence.
Dr. David Curtin is a high energy phenomenologist, interested in finding and analyzing theories of particle physics beyond the Standard Model. His area of research focuses on Cosmological and astrophysical signatures of complex dark matter. Particularly focused on Atomic Dark matter, which has deep theoretical roots in theories of neutral naturalness, and gives rise to rich dynamics that produce mirror stars and dark galactic disks.

What I appreciate about E.H. interviews is that John gives time to the guest to speak about the subject in which they specialize and never attempts to interrupt or monopolize time.

[@Mentaculus42]

How very true, one particular interviewer constantly interrupts with another question just when the interviewee is getting to the good or useful information. Sometimes a competent interviewee will circle back but rarely. Another interviewer constantly wants to show how smart they are by injecting a superficial correction to the answer or exclamation.

[@galaxia4709]

Agree. And what i love about astronomers is that they speak fluently, not too slow, and every sentence is meaningful

[@ibem6097]

Very true, and great questions

[@JohnMichaelGodier]

It's very deliberate. I see myself as the student asking the professor questions, and naturally I want to hear the the complete answer. It always drove me nuts when I'd be listening to a science interview for information, only for the interviewer to cut them off mid-thought. I often tell guests to be as wordy as they like, long answers are good, and go as technical as they like because it's a scientifically literate audience that wants info.

What if I told you Jesus on the Cross is the big bang, the number 8, and it produced two universes? My complete model of the 7 Thunders says it is so. Another mirror universe theory to check out is the one by Physicist Neil Turok. He says the big bang was a mirror. I wonder if the other universe is 2D.

“Today a young man on acid realized that all matter is merely energy condensed to a slow vibration, that we are all one consciousness experiencing itself subjectively, there is no such thing as death, life is only a dream, and we are the imagination of ourselves. Here's Tom with the Weather.” - Bill Hicks

[@blastypowpow]

Bill Hicks is one of my favorite comedians!! He’s the type of person I really like because you know he’s been a curmudgeon since he came out of the womb. Sorta like Larry David, who I also adore! I wish Bill was still with us. You have to be a certain age to enjoy his comedy because he has pop culture references from the early 90’s, but, you can trust that they were ridiculously funny. I wish Letterman had been nicer to him. That’s a sad story.

You just have to be able to understand his pop culture references from his old sets because he passed from cancer in 1994 so we don’t have anything recent to watch. It’s really so so so sad because I think he’d have a lot of really hilarious things to say about the pop culture of today. He’s a really funny comedian. An ex turned me onto him like 15 years ago.

[@TanyaLairdCivil]

If dark matter can form objects like dark matter stars, dark chemistry, interact with dark photons, etc., shouldn't this show up in gravitational waves? Maybe dark matter black holes are just the same a regular black holes, as they're all just gravity. But what about merging dark matter neutron stars? If two dark neutron stars merge, you should be able to see a signal for that via gravitational waves, but there would be no corresponding light signal. The only way we could observe it would be through gravitational interactions. To me, that seems like the easiest way to test this idea. Are there a large number of gravitational waves that carry signatures of events we should be able to see, like neutron star mergers, but then don't have any corresponding visual event? Your gravitational wave detector goes off, and everyone points their telescopes to observe the event. Then....they see nothing. Has this kind of work been done? Or do we have examples of phenomena that we have gravitational wave observations for, events that should produce a light signal, but none is ever found?

[@EventHorizonShow]

Fantastic comment and questions.

[@denysvlasenko1865]

It's worse: if dark matter self-interacts and forms dense objects, we should "see" them when they interact with normal objects. We should see numerous "binary star systems" where one star is visible (and orbits its companion) but companion is transparent (you don't see anything). We don't see anything like that in the Milky Way. Not even one mysteriously orbiting star is known. (We didn't check them all yet, but we are approaching two billion stars tested with Gaia).

[@ProfessorCurtin]

@@denysvlasenko1865 Great question. Indeed, mirror stars could end up as stellar relics that merge and produce gravitational waves, like neutron star mergers. Similarly, it's possible that mixed binaries (normal star - mirror star) form, and that could be looked for. The reason why this is not straightforward is that it's incredibly difficult to predict the rate of these occurrences, and indeed we would not at all expect the two stellar populations to lie on top of each other in the galaxy. The two types of matter have different cooling time scales, start forming stars at different times, contract at different rates during the formation of the galaxy, so by the time the stars form, their locations aren't particularly correlated, and any gravitational interaction rate (formation of binaries, mirror-normal or mirror-mirror) is not likely to be large, and completely unknown. We've started doing simulations to explore this, but it's such a hard question that we're very far off from saying anytihng concrete there. The fact that Gaia hasn't found any mysteriously orbiting stars, or the fact that LIGO hasn't found anything definitive yet in gravitational waves, does not in any way preclude this possibility (... yet). Ultimately we hope to understand these phenomena enough to disprove them, that's the next-best-thing to discovering them. Either way we know more.

[@EventHorizonShow]

P.S .....Dark Matter kinda scares me

[@martinschlegel1823]

If there are dark stars, shouldn’t at least sometimes normal and dark stars end up in orbit around each other? Shouldn’t we than see stars wobbling or really orbitting things that we don’t see? We don’t really know how big those dark stars are but we might want to have a good look at our planet survey data. And I would imagine that in most if not all theories that should look similar but distinguishable from “normal” stuff we would expect to see.

[@LaserGuidedLoogie]

Dr. Curtin is very good at explaining this. I hope he becomes a regular guest. Having said that, this seems so wildly speculative that I can't help but think this is just too bizarre. One thing that immediately comes to mind is black holes. If this "Mirror Matter" exists, it would form black holes, and those would merge with normal black holes. So we should expect MORE, or larger black holes, than is predicted to form the SM. This would seem to be an obvious observational opportunity, if this is true.

@bipolarminddroppings if the forces were equal probably, but if they were different, say like gravity and em charge, I think you could end up with something like the galactic halo that is being described here.

[@MaxBrix]

What am I missing? I thought the dark matter halo is spherical and puffy because it does not self interact. Dark matter only interacts through gravity and collisions are rare. If dark matter can interact with it's self and emit dark photons condensing into denser matter then it seems like we loose the one of the main properties of dark matter that we use to explain observations. Mainly the galactic halo structure that has been observed in gravitational lensing and is vital for explaining the rotation curve of galaxies. So, if it self interacts and can collide what makes it not collapse?

[@beatsntoons]

I know we always say dark matter and dark energy are different things and we shouldn't confuse the two, but could dark energy be coming from interactions in the "dark matter" part of the universe? Einstein's cosmological constant is the leading candidate for dark energy (although I don't know if it explains the various increases in expansion that have happened) but that's just a number... what exactly is it? Could it be something that's happening in the part of the universe that we can't see? Maybe pressure from dark matter vs dark anti-matter collisions?

[@gibidygubidy]

[@adambrain8365]

Holy acid trip! This scientist is answering questions I’ve been asking myself for years. I’m only half way through, and I’m surprised the MACHO wasn’t addressed yet. But what if neutrinos are to baryonic matter as dark matter is to baryonic matter. In that case it is, “turtles all the way down.” Just bigger and smaller turtles. This right here is opioids for my curiosity seriously.

[@mahatma_gaudi2938]

Damn, this guy can explain stuff

[@EmeraldEyesEsoteric]

Perhaps nothing actually changed. There wasn't more matter then antimatter, rather when the process of collision was finished, two universes were produced. One of Matter, and one of Antimatter. The construct of the universe is the even numbers, so the symmetry should be perfect.

[@cameronmccauley4484]

I thought QCD axions were more likely now than WIMPS considering the wave like scattering we’ve been detecting with gravitational lensing in the last 2 years?

[@mak-mikko-karjalainen]

When it comes to voids in the universe and concentration of mass to wall and chains... it probably is thanks to some space-time whirling during big bang. Like in a streaming river. There is not mass center, just a whirl that pushes everything out of the center - and once it loses energy of the rotation - there is empty space left.

[@dreamok732]

Many thanks to you and Dr Curtin. So, 80% of the effects of gravity needs to be explained and the theory of dark matter provides a possible candidate. The anomalous cosmological observations are involved with gravitational lensing, and with the awkward fact that spinning galaxies don't fly apart. The initial dark matter model to cover these observations, based partly in Super Symmetry, would give us WIMPS in a non-collapsed, non-interacting, spherical cloud of dark matter around a galaxy. However a later theory holds that the observations could be just as well explained by a model in which another 25% (say) of the 80% is not WIMPS and does collapse into a galactic disks containing the dark analogues of the observable universe (in which we liiiive). I very much like these ideas from an SF point of view but it seems to me that the cosmologists and particle physicists supporting dark matter and dark energy have too many angels dancing on the head of a pin and William of Occam might have something to say about it.

This is nearly as if the universe in itself contains its nonexistence, as if it had planned on the physical level the possibility of it not being and which would be translated as a physical model with particles and periodic tables. It’s a sort of back up or guarantee that if there’s nothing and someone might ask why is there nothing and not something or if there’s something and someone asks why is there something and not nothing, then the universe would have an answer for both situations or scenarios.

[@darthjarwood7943]

There's a Netflix movie and a manga, but it's essentially about a solar system-wide Winchester mystery house-style pointless ecumenopolis built by AI machines humanity lost control of a few thousand years before the story begins. Nihei wields scale extremely well, the main character comes to a gargantuan empty space he's told is the diameter of Jupiter, earlier he says he came from "3,000 layers below", and the view from the top of a layer is shown to basically be a passenger airliner's cruising altitude.

[@matteogiberti3297]

Wonder what causes interactions between particles... why some particles do interact with others and others do not. Also why particles are what they are... why an elementary particle as the electron has the exact same charge as a complex particle as the proton (made by three quarks) so to form atoms that can be electrically neutral... that cannot be a councidence... etc.

[@bipolarminddroppings]

The answer to that can be found by studying a physics degree, with a focus on particle physics. We know why pretty much all known particles interact with the forces they do, and how. Its just mind bogglingly difficult to explain in a few paragraphs, or a KZbin video, though I'm sure someone has tried... For the proton its easy: 3 quarks make up the Proton/neutron, they have fractional charge of either -1/3rd or +2/3rds. Depending on which way you combine them, you get either a neutron with zero charge (2 downs and an up) or a proton with +1 (2 ups and an down). You can get other combinations of quarks that produce unstable particles with +2 charge (3 ups) or -1 charge (3 downs), but they dont last long enough to make atoms etc.

[@denysvlasenko1865]

> why some particles do interact with others and others do not. It's trivially visible by looking at the Standard Model's Lagrangian. If two fields directly interact, the Lagrangian will have a corresponding term with these two fields (or their derivatives).
