PBS Spacetime reminds me of my grandmother. Seriously. One of my favorite phrases she taught me was: "I'm smart enough to know, I'm not that smart". Other science shows I watch (including other PBS channels, literally a lifelong viewer of the organization) do teach me a lot, but I have no difficulty understanding them. This channel has me struggling, yet I still learn. I absolutely adore that! Thanks to the entire team for keeping me on my intellectual toes!

Because no one knows the truth of the cosmos ( infinite or finite / endless or temporary) much speculation, imagination, calculation and modeling has been acceptable, and taken by consensus of opinion to be the most likely true. To say that "the universe is expanding" is an absolute term , which does not conform to observation. All things within the cosmos are temporary but not the universe as a whole , all part of it are fractions of it , endlessly recycled. Which means there is as much negentropy as there is entropy ie , creation ( negetropy) is a continual event at the same time as destruction (entropy) . Or we can believe that all time, matter, energy and space itself appeared in nothingness without a cause , and certainly without a creator entity of any kind since there would be nowhere for them to exist. The choice one has to make seems simple yet it has profound consequences. Science cannot prove or disprove either case, currently and never will ( that is the nature of infinity). Did the universe have a beginning or not. ? This is fundamentally a choice that everyone eventually makes , regardless of it being chosen consciously or not. Dose your universe have a boundary or not ? We are a separate and a part of the whole at the same time . Since all we are comes from here and shall return to here , in this sense we are eternal , but in our life time we are separate and temporal, just like "every - thing" . There is no other place one can be. either as an entity or dissolved energy, mater and patterns. In dark matter , it could be that our maths , simply does not work at that scale.

Probably some new rules of physics that we haven't discovered yet because the material we need to study is a little beyond our reach and/or we're not sure where/what it is or how to find it. It might not even exist but could just be a tweak we need to make to a rule or theory we've already taken for granted. I really don't think it's exotic matter unless it exists in another dimension or 'brane' that extends its reach into our 'neighbourhood'. Of course, if that was the case we would still be no further ahead cuz we still wouldn't know what it was... we'd just know where it came from. Of course then we;d need to find out where "that" was. On and on it goes, curiouser and curiouser.

Question: if time were to be warp in certain regions for reasons unrelated to the density of particles, would such warping have an effect similar to what we describe as dark matter?

Are you familiar with the work of Mariateresa Crosta from INAF? Using data from the Gaia probe, they modeled using relativity and the precise proper positions and motions of stars in the Milky Way. And it seems that in this model, dark matter is not necessary for the Milky Way to move as we see it moving. What do you think? Greetings from Argentina.

Could “dark matter” be the lack of stuff? Like a low pressure region of space? Assuming that not all parts of space are expanding at the same rate, could the faster expanding high pressure areas of space be curving space toward the slower expanding lower pressure regions of space?

@ I’d love to know if it is true that not all points in space are expanding at the same rate. If so, why wouldn’t a slowly expanding region of space, surrounded by quickly expanding space, create an effect similar to that created by mass/energy? ( .i.e. similar to the way that high pressure and low pressure works in our atmosphere ). I don’t know anything here, but would love to hear a discussion on it and assuming I’m wrong, learn why I’m wrong.

@@maxmusterman3371 The loss of energy is proportional to the speed and mass of the object. This is why merging black holes produce the most powerful waves, they are both heavy and fast. We can detect nearby merging neutron stars but not, say, merging white dwarfs. The energy Earth loses in this fashion is estimated to be enough to power a dim lightbulb. WIMPs would be far lighter and orbiting far, far slower. All the stars in the galaxy would fall into its core before the dark matter halo contracted significantly.

Say 2 rocks are gravitationally attracted to each other in space: when they make contact (thanks to electromagnetism), their relative velocities become zero, and the kinetic energy just converts to heat or something. If they couldn’t physically interact, they would pass straight through each other and keep going; any energy lost by one would be exactly gained by the other. If dark matter can only interact gravitationally, then it can’t clump up because gravity alone can’t bring the relative motion of 2 ghostly moving objects down to zero. Even if some dark matter particles entered some kind of orbit, it would just take a little interference to scatter it all apart again.

@@j.f.fisher5318 I believe the revelation will happen when we let go of the assumption that the observed phenomena is *IN* the observable universe instead of a consequence of effects happening "underneath" the observable universe. If you extend GR to not just be a deformable sheet but actually surface tension, and then assume that there is a bulk four-dimensional fluid underneath, and then further assume that this hyperdimensional fluid is flowing, as if the observable universe is just a small patch on the surface of a stream, then you get all of the effects of dark matter and actually even dark energy while you're at it without the need of special particles. Spiral galaxies are really just micro eddies in this stream which really do form depressions that the flotsam of normal matter just falls into, but it's being convected along the streamlines of the vortex in the stream. To us, it looks like the center portion of spiral galaxies move too fast, and under the gravity of the accrued matter, it does. But if it's being pulled along, then it's perfectly normal. Let's look at the Great Attractor. This is just the effect of an undercurrent in the great stream. The Big Bang did not create all of existence, but rather was a consequence of a splash that happened on the surface of this stream. The real problem is that the scale of the observable universe is insignificant compared to what is beyond, which we will never know.

I have said elsewhere that inviolate CPT symmetry implies antiparticles are traveling backwards in time, the big bang created equal particles and antiparticles, but they quickly separated, the antiparticles going backwards in time to form the previous universe, which we see as a universe undergoing a big crunch (and they would see themselves as expanding and us as collapsing). If as this episode suggests, dark matter is also a particle type created at the big bang, but there is a problem with dark matter antiparticles, the time reversal of antiparticles also completely solves this.
