I don't think it will be that hard. Physicists approximate ALOT. You can tell if I am wrong. So you just need to look up the dark matter density per cubic light year. Find out the density of a plank relic and divide both. The number you get is the number of relic you are gonna find in cubic lightyear. Of course you can make it more accurate but anyone can do this.

[@LuisAldamiz]

@@admiralhyperspace0015 - But that's not how you calculate the number of Planck relics there should be per the Big Bang parameters but the number of them needed to make up Dark Matter. Such result would not be a theory but a theoretical expectation. What Matt did (I understand) is the former: estimate how many Planck relics there should be based on what we know (or think we know) of the Big Bang and then, only then, compare their collective mass to Dark Matter.

[@whifflingtove]

@@admiralhyperspace0015 you mean anybody who can do algebra and can look up these numbers. That may be about 20% (maybe generous) of people?

It's amazing that science fiction movies can parade themselves as science fact. I'm sure everyone is working on that elusive Flux capacitor that makes time travel possible. Warp engines and FTL drives are just around the corner because they're in all the space movies. What the clueless public fails to comprehend is that if a back hole generated so much force that not even light could escape, the entire galaxy would have been swallowed up by now. Oh, wait. The inverse square law states that force decreases with distance so anything outside the event horizon isn't affected. Then explain why objects that are 50,000 light years away from the galactic center are still 'gravitationally bound' to the center. Oh wait. Let's just make 95% of the galaxy dark matter. Do you see how ridiculous your science has become? You like movies so much, here is one for you. In Get Smart, Maxwell Smart was always asking 'Would you believe'. Intestellar is doing the same thing. Would you believe our version of a black hole. Ill leave you with a Dirty Harry line. Do you feel lucky? Well do you punk? How do you know what they are telling you is true? They've provided both evidence for their claims. Only conjecture and suppositions. I can tell you for a fact.

Remembering that they are that which can answer why their is something. Instead of nothing(science explaining it away as a dmt ketamine trip tho in peer reviewed trials unable to duplicate even 1 with such consistency. It tells us how unquantifiable reality is. Yet science is lorded as proof of existence being spontaneous and acknowledging energy can neither be created or destroyed, Harold a theory as their proof of no afterlife or a "God" like being giving a reason for something instead of remaining nothing. Complete lack of fundamental processes of everything, or inability to define quintessential fields; gravity, matter antimatter ratio, the rate of our universe's expansion. What happens in black holes. Or in my case explaining that 1 ufo which was so undeniable in daylight.

Mathematical equations support possible # of dimensions at 11. Quantum physics can't link up with the big bang theory so we know that something is missing. Or the egos in search for self confirmation bias & with correlation between verifiable science and a theory they become as certain as creationists are. Neither having physically proof of either concept yet utilize it as proof positive. Only a fool is certain- a genius. I was guilty of this too. However when someone shattered my reality I started reassembling the puzzle with new pieces. The scientific community has been known to rule out theories with small odds or deny evidence outright.

@@AlphaTechN much love for the compliment. & One day I was walking home from my friends house in the summer of 2001, wasn't quite sure until I Googled a game my friend was playing right before I left this house to head home on the path that I traveled as much as was possible. Which ended up being about 4 times a week 4 months on end, it was summer break and I had just turned off the people's Trail to cut through a meadow with a sort of valley and as I got down the outside slope I looked over, looked back and immediately looked at the craft again in a proverbial double-take. What I saw was no further than the length of a trailer in a trailer park Plus the road in front of it, I stood staring while I was deciding whether or not to run home and tell somebody but I thought I should stay because it would probably fly off before I had the chance to so I might as well use the most of my time for disappears memorizing this thing, which I can still see if I close my eyes and try to picture it. No I don't have a picture perfect mind but in this particular instance I've been able to recall this one moment with a quicker more detailed play by play and snapshots along the way. I asked him if the size of the craft was 50 wide hovering silently and still in broad daylight midday, for at least 10 minutes but my instincts tell me it's more like 15 to 20 but I have no doubt about saying 10 minutes of my life was spent looking a UFO. The Craft Encompass more of the sky then the water tower in the background, it had a saucer like top, a cylindrical middle section, and a cone which is like the bottom of a toy top. The cylindrical body had what I can only describe as an LED board that has pixelated colors crashing into each other like waves. After five minutes with only estimated 10 seconds with eyes not eagerly glued and studying The Craft. So I thought well I could have made it home and share this experience with somebody else however when I got home I was so excited I didn't think of how to call for my mom other than come look hurry there's a UFO in the sky, her response was sure there is and then chuckled. Well the phone(house line) was in my hands dialing my friend's number who I was thinking might be more apt to look so I just said whatever ringing my friend whose house I just laughed and presumably should be able to see it but I didn't want to scare him so I asked him to look outside and he wouldn't until I told him and after I told him and I could feel him judging me however I didn't mind because I knew I was right which would be tough cookie to crack for any person who hasn't actually seen themselves. so after becameclear that I probably was the only one who who would ever know that on that particular day a UFO hovered over Heritage Heights. I was frustrated that I couldn't share my once in a lifetime experience with anybody who wouldn't doubt my words. I was I was I was then pacing I was pacing from window to window then pacing from window to window 2 window and in the span of 3 seconds tops in between Windows it disappeared from the 180 degree view of the sky. and after running back to the last that I was told UFOs don't exist in people that see them are crazy all the way up to the moment I turned my head chanced my perspective had shifted. at the time I was certain it was aliens however in Columbus Indiana near the City of Edinburg we have a very large military installation called Camp Atterbury that is widely known to the public and provide me with a Baseline to compare Jets planes and helicopters with and commonly the house would rattle because they have a missile testing range, and after hearing about Bob Lazar and element 115 along with his many other degrees of accuracy such as the bottom of the spacecraft tilting up facing the direction it would fly. Which btw perfectly described precisely what one of the three admitted us navy recordings. The Pentagon acknowledging the validity of such videos gave me all the room I required keep backup UFOs perfectly describes judging by the and after a couple more seconds I worked up the courage to go back outside and check on the other side of the sky which was clear. I became scared briefly once I neared home because it then dawned on me oh, wait people get abducted by these things so I ran and got there quickly but the fear immediately subsided once I started walking up the back patio steps. I only mentioned this to three people who I loved and trusted. my mom who still remembers the day I came in talking about UFO, my friend who played the game instead of looking, and my girlfriend who didn't believe in any unexplained phenomena. my girlfriend believed me because she could hear the sincerity in my voice in I I consider myself a bit more than just a tad clairvoyant and maybe the connection we had allowed her to be so certain of my claim which leads me to my next one of which only 90% confidence and 10% doubt the the following encounter describes. After hanging out at her family's we were on our way home driving through the countryside and my girlfriend what was flickering and she immediately said Stars before she even looked in the direction I was talking about but I said no that's not a star and I can't remember precisely what she would suggest the mini blinking lights where however her escalation of rationalisation. I remember her saying that they would all stay off and to look because she told me so and as if On Cue the lights began blinking again. And with a scared shaky voice she said I don't know let's get out of here which I would happily obliged but I never suggested what we saw was there a UFO even though she knew I had my own and & Interesting in hindsight we didn't even talk about it for about 2 weeks. we were both have normally tired unusually early, which has happened to me once since then, which has happened to me once since then that I can recall which involved missing time, standing seeing three Grey's through my blinds on the front door, I open my and I'm now lying on the couch still in my work clothes and not even a pillow or blanket which caused me to immediately run to my door and look out of the blinds and eventually Peak outside to see nothing. and last to leave one month before that I saw on the same houses front porch light reverse the night sky which I happened to record as a video on my phone but the video camera was reversed to the ground even at my phone to make sure I had the right camera facing the correct direction ,but I did notice a photo which was completely black of the night sky because it had no stars out that night and there was one point of light that was so small but was able to zoom in and see presumably half of a saucer but at the very least suspended in I have presumed 50% sunlight. my Thanks goes to all whomever work on this project, because it is a worthy topic of study and your disclosure efforts mean a lot to at least me

[@gravoc857]

It depends if a Planck relic functions like a black hole. What would one infinitely dense particle look like? Would it still be powerful enough to absorb nearby mass?

[@TheZenytram]

we dont know how gravity works in that scale. and is possible that they cant be attracted to each other cus they're too light so other objects pull them before that happened.

[@thefourshowflip]

@@gravoc857 I hadn’t really considering that question, though shouldn’t we still expect them to occasionally physically collide with one another, even if we assume they have zero gravitational potential? The frequency of such collisions may surely be low but given the sheer numbers in question and time scales involved, it seems that collision frequency just can’t be zero. (Forgive my sloppy jargon; never took GR during my BS...and we never got to this fun stuff in my cosmology class)

[@denalozecon9074]

Occasionally? Black Holes this small would be somewhat similar gravitationally to electrons, but no electric charge. Gravity force between two such Black Holes would effectively be undetectable at distance of even one micrometer; gravity halves for EACH doubling of distance...10exp-35 would be ? So at distances of even one millionth of an inch the two black Holes gravity would be too weak to attract each other. Unless gravity fades at differing rate at small scales, and no evidence for that. It's similar to calculations of Andromeda merging with Milky Way; most stars would not hit anything larger than cosmic dust. If hundred trillion of the tiny black Holes fly towards one cubic meter of space...imo you'd only get dozens of impacts and rest just fly past echother.

[@CATinBOOTS81]

Well, assuming how small is a Planck relic, and how far they are if they constitute the majority of Dark Matter, and how weak gravity is, I assume it's probably an event very very very unlikely. "But with the passing of strange eons", even that could happen :)

[@garethdean6382]

1.) Such relics may leave faint traces. Detecting them is part of our general approach to trying to figure out dark matter. They may be (dis)proved by theory or observation first. 2.) There are theories based on this. On universes having 'offspring' and thus being liable to evolve to maximize black hole production. So it's not too stupid.

[@isthisagoodyoutubehandle]

Perhaps this could also solve the mystery of matter/anti-matter asymmetry. Think about it. What if the antimatter we're missing didn't just annihilate, but instead formed these relics? Being contained within this singularity, it might be that this shields the mass from being annihilated completely as it's stuck in a seemingly eternal, isolated "relic space" that can only interact gravitationally

I guess the numbers given by Matt are averages, and that the individual black holes probably only exist in this 30 km2 volume for a really short time.

One thing that’s always bothered me: given the density shortly after the Big Bang, how did the whole universe not collapse into a black hole? Is there a “speed of black hole formation”?

[@TheZacdes]

A good question. If inflation had not occurred thats probably what would have happened!

[@paulollerhead941]

Black holes and white holes are the same thing. The Big Bang would “appear” as a black hole from outside our universe

[@JrobAlmighty]

Well both states represent a singularity so in a way it was a black hole insofar as it's singularity is concerned. I know there's a strong reason why that's not necessarily so but I can't seem to recall it.

[@danieljensen2626]

I think we can thank cosmos inflation for that. But also yeah, sort of. Black holes still obey regular principles of mechanics (accounting for the distorted space around them), so it would take some time for the matter to all collapse back together. Black hole mergers as seen by LIGO are a great example of that.

[@straft5759]

Yep. We can describe the effect of gravity intuitively as space actually moving. So yeah, the reason why things even fall into black holes in the first place is because space is ‘moving’ towards them. BUT, and this is a big but, expansion of the Universe is also a part of gravity, in the sense that it’s moving space itself. As mindblowing as it may sound, event horizons are actually smaller due to the expansion. This is negligible today, but it wasn’t during the inflation, when space was expanding so fast that it pulled mass away from even the most massive black holes, leaving them with, think about it, no mass at all! Why? Because such massive black holes didn’t even exist! They didn’t have time to form, because of the exact same effect, combined with the already low number of black holes, which is due to the effect, which is due to the lack of black holes, which is due to the effect, which is... you get the point. Hopefully.

[@scratchgolferroadtotheseni8858]

Hey Space Time! Just started watching and subscribed. Three questions: 1. Is it possible that our universe is just an overweight black hole that had "supernova like" explosion inside an greater universe? 2. Maybe white holes are dark energy hyper expanding our universe? Since we know that black holes manipulate space time, white holes could expand it. 3. Can salt water, placed in a lifting balloon that pops at high altitude, seed rain clouds in California? The idea is that you use solar panels to heat up and send up salt water balloons which pop at high altitude seed rain clouds. Whatcha think?

[@fensoxx]

Question: this didn’t get touched on and I was waiting for it... can these Planck black holes feed and grow again? How can the “one per city” bump up against matter and not absorb it?

[@MRichK]

Their interaction cross section is so small that they could go right through a proton and not interact with its parts, that is, the quarks, and gluons, and such inside. So another way to say it is that the probability of interaction are very very low. However, these are outside any current model's applicability. So we don't know how they would interact except we can put limits, because if they were too active we would already have detected them.

[@fearandclothing2403]

I was thinking along similar lines... if these are in fact dark matter then they interact with regular matter through gravity. I take the point that their small size would mean statistically they would likely reasonably easily pass through normal matter with very little interaction except with a subatomic particle here or there. But if they do interact with a subatomic particle then they should absorb it and grow in mass, very shortly thereafter radiating that mass away as Hawking radiation at a very low wavelength. Could one estimate either amounts of gamma rays generated or mass loss from a region of space given a Planck relic density, even if it's too small to be measurable?

[@iainmoncrief1436]

They would probably be too small to even eat an electron. I’m wondering why these wouldn’t just accumulate at the center of stars, merge, then swallow the star.

[@skyrask1948]

@@iainmoncrief1436 There would be no reason for them to accumulate in stars since they would not experience any drag since they would not interact with matter. Therefore if they fall towards star because of gravity they just pass strait trough it. And on top of it if two of them merge then by Hawking radiation half of its mass would evaporate rather quickly. And there would be one less of them. So theirs growth is only possible if there is such amount of them that merging can overtake speed of evaporation which is fastest just before it stops.

[@cancan-wq9un]

Any matter they randomly absorb most likely turned into hawking radiation quickly. They have to run into lots of condensed matter which they cannot immediately emit back as hawking radiation. And that amount of density is probably a lot, since even neutron stars don't turn into black holes at random.

This is a theory I've been espousing for decades now. Kind of helps explain gravity as well. The kitsch is that these black holes would have to be sub-Planck length in size - enough so that a normal 'particle' is way to massive to ever fit through the event horizon... therefore, generating the strong nuclear force at close distances, the weak at greater (but still atomic in nature), and then gravity over larger distances where a massive collection of them combine their attractive forces. Since normal 'particles' are too big to pass through the event horizon, the black hole gets 'clogged' up and our reality experiences their effects as the above mentioned 'forces'.

@@SeveralGhost I would say recirculating, as matter cannot be created or destroyed as our universe and other parallels have a 'set' amount of matter and white holes essentially act like a membrane between universes. Another thought is how the vacuum like a black hole or water circulating a drain works in that it is focused, however a white hole is similar to an explosion, where it is everywhere. Just a thought! Cheers! 🤓👍

[@pieroluciano3272]

@Achyut Pandey The 'fabric' of our universe, I believe is like a sponge (not solid), when you look at space in its smallest form, I think that is where certain types of energy can pass through both ways between universes.

[@pieroluciano3272]

@Achyut Pandey I agree with you and I like the way you think! 🤓👍 These white holes are volatile like you say and probably last only a millionth of a second, but they surround us (pop up and die) all the time. Since the Plank measurement is the smallest that man (unless recently updated) has been able to measure, I would say that white holes are indeed smaller, and the reason they do not form black holes is because of their nature, the fact that they are woven in the fabric of space. Black holes, essentially are concentrated extremes of gravity and these white holes are insanely small. The reason why they wouldn't just concentrate together in a clump and cause a rush of unknown particles to pass through is the million dollar question! I always believe that the answers to all of our scientific questions lie in the 'microscopic' unknown. For all we know black holes in other universes are what power white holes in our universe and vise-versa! like a ying and yang as universes support other universes like a structure.

[@MaryAnnNytowl]

@@pieroluciano3272 white holes? LOL, no. There has been zero evidence of anything resembling a white hole, ever. Black holes were found, relatively easily, and they produce no energy unless they're eating. White holes, if they existed, would be visible very easily, and show up wherever they were. None have been found. Therefore, none exist.

7:45 Just an idea: during the matter/antimatter annihilation phase where matter won the battle, what happened to all that excess energy? Could those annihilations be the source of the primordial black holes?

[@Dabaiko]

There is no annihilation phase, it's just an analogy. You can look into the Casimir effect. This is why dumbing down theories to make them accessible to eveeyone is a bad idea when you don't disclose that you just described a model that can be used as an analogy but nothing more. You can't actually work with these concepts at the level presented in the video because we are neglecting tons of data (which would make the video boring and difficult if they were included). That's basically why we can't become PhD by watching flashy youtube videos

[@jeffreydungan1377]

From what I remember from a different SpaceTime video - it's expressed as photons, which outnumbers particles by about one billion to one. And this helps explain the photon-particle ration we see today.

[@nabuconolosor8]

If there are tiny black holes, wouldn't they eat everything in their way and get bigger ? Are they also limited in what they can eat ?

[@autarken]

Had the same question... so let's say there's a tiny black hole somewhere in a city... somebody collides with it, what happens?

[@nevar108]

These black holes are small enough to pass between atoms, much like a human scale space ship slips between planets in our solar system. It might actually be closer to how a space ship passes between stars or galaxies. ...

[@BattousaiHBr]

but black holes also evaporate, with the rate of evaporation being inversely proportional to their size (which is to say, one this small would instantly evaporate away whatever they happened to gobble).

[@mitrovarr]

Aside from slipping between particles due to their tiny size, if they did eat something they'd be able to emit hawking radiation again and spit it out as energy while dropping back down to the minimum mass. It would probably look a lot like a regular particle collision.

[@Ex-expat]

Yay, new episode ;)

[@johnt836]

10:56- the video text says one plank relic per 30 km^3, which is wrong. What is meant is one plank relic per cube of space 30 km on each side. I did check the math, based on a paper I found online that estimated our local dark matter density at around 0.36 GeV/cm^3. That is about one 20 microgram mass per 3100 km^3. That's about one plank relic per cube of space that is 31.5 km on each side.

[@eachus]

I just tripped over a nasty fact. I consider myself a mathematician. The real difference between mathematicians and scientists is that scientists disprove things, and what is left is science. Mathematicians prove things. Mathematical facts will never be disproved, even though new math like non-Euclidian geometry (not that mess taught in elementary schools a few decades back) isn't ruled out, until there is a proof that it is. About the time Einstein developed General Relativity, Kurt Gödel proved his incompleteness theorem. Any mathematical system of sufficient complexity must either be incomplete, or inconsistent. Inconsistent means you can prove zero equals one or other screwy stuff. Right now both General Relativity and quantum mechanics are incomplete, as is the standard model of physics. Since these three systems are sufficiently complex (and they are way more complex than Gödel’s proof requires, combining them into a “Theory of Everything” can’t happen no matter how many new particles, forces, or dimensions are added. Is there any hope? Sure. Dark matter and dark energy can be explained, and there may be a more complete version of any of these systems. But more complete is not total completeness, and can never be.

[@isolationnationn]

@@eachus Can you link this paper for the Kurt Godel proof so I can have a read? I can't figure out how you could say these systems can either be incomplete or inconsistent, as a guarantee, without making unscientific/funky math assumptions along the way

[@davidcapes1567]

@@eachus Not necessarily. Just because a system is incomplete doesn't mean we can't form a theory of everything. Gobel's incompleteness Theorem simply states that there are some true statements that can't be proven true from the axioms. We don't necessarily know what these are, we could be able to form a theory of physics or system of maths where everything we would need to prove is probable and only niche miscellaneous stuff isn't. We simply don't know

Time: A singularity point dimension, with only one direction. Forward in time. Time rules: 1.Warps to keep order of particles forcing inflation of singularity. 2.Elementary particles travel in single file lines. 3.Speeds up & Slows down to keep memory/light speed constant. 4.Keeps copies of particles binded into matter. Space - A space created by particles colliding while traveling through time. Not a part of time exists in the same space as time but they are different dimensions hence spacetime. Outer Space - A space created by inflated spacetime traveling through time. Vacuum not related to spacetime envelope no connection to the singularity of time other than the entries that recycle matter from the vacuum, the infamous blackhole.

Sorry, I can't resist a contentious contention: There can be no theory of quantum gravity because that would require combining a model that describes for want of a better word 'reality' with a model that describes an 'emergent property' of that 'reality'. They are quite different concepts and so cannot be directly combined as if they were different descriptions of the same thing. The relationship between Quantum Theory and Relativity is one of a model of 'fundamental reality' and a description of 'emergent behaviour' arising from those 'fundamental rules'. There can be no way to combine the two until we work out how to accurately predict emergent behaviour - indeed it's hard to be absolutely sure which is 'reality' and which is the 'emergent behaviour'. To put it another way if Quantum Theory is the set of rules by which Langton's Ant moves then Relativity would be the highway it eventually creates, or vice-versa.
