Black holes and beyond: The latest findings | Penrose, Natarajan, Carroll, Weinstein and more!

What is the latest thinking on black holes? Why have they remained so mysterious while scientists recognise their essential role in the creation and future of our universe? What will come next?

Join the world's leading scientists and philosophers as they discuss their research at the forefront of our understanding of black holes (and wormholes!) and where they are heading to next, including Roger Penrose Priya Natarajan, Sean Carroll, Amélie Saintonge, Matt O'Dowd, Paul Davies, George Ellis and Eric Weinstein.
Join the debate LIVE with some of these very speakers, including Roger Penrose, at the upcoming HowTheLightGetsIn festival in London on 21-22 May 2024!

What more might we discover about black holes? What do you find most interesting about them? Let us know what you think in the comments!

After a couple of whiskeys and a few beers, this was a perfect nightcap.

[HeathenHammer]

Ever since I knew and understood what black holes were, it didn’t take long for me to start thinking that they are how universes get started.

[RayPierreWhit]

Where do I go to ask about Zeno’s Paradox and continuous vs discrete space?

[Lackiiiiii]

Ripped a couple phat bowls it’s time to watch and not understand but still be fascinated

[IWillSayMyPeace]

So speed of light is needed as escape velocity to escape from the grips of a black hole, but! it's called a black hole because not even light can escape it. Mind. Blown.

[donahunt]

im thrilled that prof davies and i have had the same thoughts except i didnt envision a connection with wormholes

[NatrajChaturvedi]

If blackholes have varrying sizes then I dont get this thing about all the matter being situated at a single point of infinite density within a blackhole. I mean these supermassive blackholes have event horizons that are so big compared to stellar mass blackholes. So obviously the matter fallen in, whatever form it takes, is occupying more space?

[ConnoisseurOfExistence]

Great video and I think more videos like this should be made. However, I personally did not learn anything new here. I guess our knowledge about black holes is pretty limited and most of it can be easily learnt even by curious non physicists...

[amedeofilippi]

As far as i know all stars are rotating, thus all stars have a certain angular momentum that has to be conserved while they are shrinking to become black holes. Has anyone considered this fact which should be opposing to the formation of a singularity?

[zackeryburch]

If in theory the universe was finite, and gravity was just the result of matter “pushing” on the empty space and that empty space pushing back, we should be able to calculate the size of the universe correct? Personally I’m not a fan of any of our current models of gravity.

[Sarita]

There is a geometry that would not have been graphed yet, and that includes the time-gravity factor. That is why that "pop" in which the black hole "disappears" would demonstrate the continuity (which we do not see optically) in the development of another big bang outside of our time.



[proteusaugustus]

The second universal law of energy conservation is E=TC^2, which is my Smith-Borden 3T Proton Model that comports with energy conservation. The proton is a battery. I explain my model on my Rumble channel.

[Blindseeker]

iai long form on youtube! Thanks. More please?

[donahunt]

i think when this area reaches "infinite density", that "pop" is when it TEARS the FABRIC of SPACE TIME and essentially becomes the big bang in another dimension...when this singularity becomes so dense that it pierces space-time, it is the genesis of another universe in a different dimension or reality 🤔

[jamesruscheinski]

when star collapses into a black hole, is quantum interior of black hole produced? matter is crushed into quantum black hole?

[OpenWorldRichard]

Rather than assuming that mass collapses to a point violating the laws of General Relativity we should instead look for an explanation that conforms to general relativity.

Suppose a black hole contains a neutron star. A neutron star is a very dense object and we can work out the size of a neutron star that would be needed to form an event horizon outside the surface.

It turns out to be 3.4 solar masses which gives the prediction that all black holes should be greater than 3.4 solar masses which is as observed.

We do have rotating black holes which also invalidates the singularity hypothesis because a singularity cannot have angular momentum.

[ricardonabeiro]

23:38 what’s is let “x 1, 3” Eric Weinstein was talking about Einstein relativity theory?! Suddenly I felt dumb, but maybe that was intended by the way he speaks to the more general audience.

[robertm]

Carroll made the most sense(at least to a point 01.12). There is no infinitely dens etc infinitely small, but something we don't understand yet today, obviously.

[SurprisedDivingBoard-vurz]

They are singular poles with extremely dense magnetic fields surrounded by electric emission.
