Primordial black holes may be lurking throughout our universe. How large are they, how many are out there and what would happen if they moved through our solar system?

If we found them they would tell us a great deal about the origins of the cosmos.

the biggest black holes from the dawn of time are arab brains. lol.
-
Isn't density at the period immediately after the big bang kind of a moot point since space was expanding faster than the speed of light, most particles were, in effect, moving apart?
Stars couldn't even form until inflation had "slowed" down and Hydrogen could form and start to clump. -
these guys are some smart mofo's

Cthulhu Fhtagn.

To reduce the possibility of cross contamination between Earth organisms from other planets, they would need to satisfied the Coleman-Sagan Equations.
-
Let's face it, physicists don't know shit about the origin of the universe.
-
We're all living in a black hole.......kappa
-
Would it be a good idea to do a video on if light went at the speed of sound
-
Seems even Youtube video can't escape from blackhole. Internet browser decided to crash right after I heard words even light can't escape it :) Nice coincidence now when thinking it.

How can you hide a bunch of holes? Worked in Blackburn, Lancashire.

PBHs are everywhere if they were the seeds for galaxies (including the Milky Way). Perhaps we first we need to appreciate that galactic PBHs act as matter recyclers by spewing out subatomic particles along their equatorial planes, thus generating recombinant hydrogen along those equatorial planes, producing stars and galaxies.

Is my grandpa's butthole a PBH?

proton sized back holes aren't stable to last more than a billionth of a second. Black holes have some inherent decoherence degeneracy thus the therm "quark-gluon star" is more accurate. So mathematically you might have enough mass, but you need some extra space to fight back the decoherence degeneracy. Degenerate compressions are so degenerate that fail to be ideal degenerate objects. Degeneracy isn't ideal. The more degeneracy (degenerate compression), you have, the more jittering you get, thus decoherence of degeneracy, thus the "quark-gluon star" demands more volume and mass to cover it's non ideal degeneracy. Your mistake is the fact you don't recognize that the more degenerate pressure we have, the more jittering we get (degeneracy decoherence), thus we need more mass and volume to keep the "quark-gluon star" alive and not spontaneously exploding. You cannot have a proton-sized black hole which lasts mort than a fraction of a googolplexillion of the second, and if you want to know why read my text from the start, but now be more analytical and fussy.

I don't ever hear enough of an explanation of how the early expansion of the universe overcame the gravity of such clumps of mass. Because it seems that the universe should be a single black hole. In other words why did the big bang happen? Clearly we exist but why? Dark energy?

My two most burning questions relating to black holes:
Black holes are generally of a spinning (Kerr or Kerr-Newman) variety. What part of the black hole actually "spins", since the horizon is not a physical entity, but rather region of spacetime (my best understanding is that for the singularity to spin, it has to have a "diameter of spin" of at least a Planck length for its "spin" to mean anything, this necessitating it's being a circle rather than a point)?
Secondly, how is it that two non-spinning and identical black holes in a head-on collision wouldn't reveal naked singularities? Wouldn't the geodesics in between them be equally "bent" in opposite directions, thus negating the curvature for however brief a moment? I understand that there have been simulations performed and upholding Penrose Censorship, but - qualitatively - why? -
Hey PBS Space Time watchers... we have a dead subreddit over here: r/supermassiveblackhole/. Care to liven up this subreddit and discuss black holes? Head over and subscribe... We're lonely over there...

Yes! I do think there are many primordial black holes, but they fell into the other dimension and the twinkle would not be visible. Black hole mass expands in the 4th dimension, its not observable like a bigger black hole. And big black hole fill up the 4th dimension like a well.
