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.

You can pick out the few people with sense by the fact that they question obviously conflicting statements and don’t just swallow it down, looks lIke a dick taste like a dick but mr science says it’s a lollipop. So just keep sucking The whole thing is mathematical and they make statements like maybe it ways the same as a proton or maybe 1000 Times. That ain’t how math works sugar. Absolutely, absolutely absolutely he says. Absolute bullshit.

Whoa... never thought of that, but yeah: The question "Why is gravity so _weak_ ?" can be rephrased as "Why is matter so _light_ ?" 🤯

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?

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.

Mention around 8:19 of the 80% "one boring thing" is likely the same division, when considering the cultural development of humanity, and the role of genetics. Expressed directly as "intelligence", within the complex model that determines human behavior. The boring part instantly becomes less boring, when one considers the fact that "The void does not move."

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.

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.

The thought that there is an entire universe teeming with galactic civilizations just beyond the reach of our abilities to sense is nearly intolerable. Makes me feel kinda funny.

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?

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.

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.

Something that has puzzled me for a while - I've heard the speculation about DM being a spherical 'shape' which forces galactic disks to rotate 'wrong' - the velocity curve problem. But for DM to do that it has to affect matter using gravity - anything else & we'd detect it by THOSE effects. Unless they want to invent a whole new magical force I guess - not the 1st time they've done that... But how can DM gravitationally affect normal matter without affecting itself? How can you have a 'dimple' in spacetime that only works for matter but not for the thing making the dimple? It's like we've got something very basic wrong & now we are WAAAAY down a non-functional rabbit hole making shit up to try to explain why our hypotheses fail utterly to fit observations. The universe cannot possibly be this smooth & flat - "Oh there was this magic that stretched it just enough to fit our theory then it went away." Galaxies don't work right - "Oh, there's this magic particle that only interacts just enough (& in no other way) to make our theory work." Then we have the Hubble Constant problem, frantically looking around for something to erase the contradiction & ignoring that their own theory of Dark Energy postulates precisely a change in the rate of expansion. 5 bn years back, IIRC we had a change in the expansion rate & now they're babbling about it slowing down. Can they even SPELL 'constant' while they postulate alterations in that exact figure? Somebody needs to go back to Maxwell's quaternions & start over, ignoring Heaviside & Hertz's corruption of the theory & see where we then arrive. With computers we could have an entire new physics in a decade.

can there be dark matter life?

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?

Maybe some conscious being that inhabits the dark matter universe is wondering what that 20% of pesky stuff is that they can’t detect.

I’m going to eat the cheapest can of beans and bread until I have budgeted both patron subs into my life.

Off-topic, but I've thought listening to your interviews a number of times that if you don't already know it, you might like 'Blame!'. 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. Check it out if that sounds in your wheelhouse!

I wonder if dark matter beings can see our ' regular ' stars and such

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?

Lets go! 😎

What if dark matter axions are puffy because they're touching and are as close to each other as weakly interacting massive particle degeneracy pressure will allow them to be? What if thier atomic diameter is light years?

JOHN JOHN JOHN!

In the movie/tvseries Lexx, there were two universes: light and dark, invisible to each other. Dark is were all the evil stuff is, and Earth happens to be in the dark universe.

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.

Wonder what causes interactions between particles... why some particles do interact with others and others do not.

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 KZread 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.
