Sabine Hossenfelder joins Sean Carroll and Brian Greene in becoming a great educator of physics. Where she distinguishes herself is her uncanny ability to take what are arguably abstruse subjects and concepts and explain them with unequalled clarity and economy. My hope is that countless others will discover her powerful and disciplined intellect and polished communication skills, thus allowing them to better understand our physical reality at a quantum level.

A more fundamental definition of information is, whether a system's information at time t is always 1 to 1 related to the system's information at time t+1, regardless of whether you could predict or reverse engineer it.

I just recently discovered your channel, and I am so amazed at your ability to explain things clearly. Thank you so much.

Sabine gives us an easy-to-understand explanation of something that normally is difficult to understand, since black holes in space are invisible. Thank you for your illustrative videos!

I think the most beneficial quality of the way in which you explain physics in your videos is you understand the confusion that Layman would have with the terminology and explain it plainly without sounding condescending or demeaning you validate the normal person's difficulty wrapping their mind around such a complex subject that most people spend their lives dedicated to. It's not an easy feat and I have my hat off to you for it

Thank you so much for explaining this. I actually thought I didn't understand information loss at all, but apparently I had a decent grasp of it. The real issue that I wasn't understanding was the "information" part. I suspected that in this sense, information is not the same as it is in everyday language, but I've never heard someone actually say that. I also didn't understand why it is sometimes referred to as a paradox. That word seems to have more of a connotation of something being impossible or contradictory, rather than just not being understood. A lot of physics seems to use names for things that just cause more confusion.

Thank you for this video! I have seen many about this topic already and after every one I was wondering about why it is implicitely assumed in the video that the universe is injective/bijective (function analogy) and if it couldn't just be surjective (two different states just leading to the same later outcome). So glad you have addressed this. I'm already deep in your video archive and this channel has become one my very favorite science channels for a good reason.

On top of an outstanding presentation of information, your visual composition of the scene, visuals and the presenter an one of the most graphically pleasing I've seen.

HI Sabine, thanks for laying out the relevant physics so clearly (as ever)! I was wondering if you could clarify a detail in the video. You say, "If you combine gravity with quantum theory, it seems you get a result that's inconsistent with the quantum theory you started from." Surely you mean it's inconsistent with the *time reversible part* of quantum theory (e.g., the Schrödinger equation). It's not inconsistent with the part of quantum theory that's not time-reversible (viz., the measurement process-is there even an equation for this?), right? Or am I missing something?

These are very good presentations. Naturally, a very tough subject to basically handle as a so-called "talking head", but, wow! These presentations are done very well! Very interesting and highly, highly informative!

Very interesting. But could someone enlighten me about the following: if observation is not time-reversible (which happens all the time) 3:19, why are we bothered by black holes not being time-reversible?

We should be thankful that physics finally has a non-unitary aspect. Because sure as hell, there is an arrow of time. Irreversibility is not a problem; it's a boon.

Simply a tool in her toolbox to help her educate and grow the channel. She's clearly not stupid.

Concisely and clearly explained ! Thank you !

What a succinct and elegant explanation.

Jesus, you're bloody gorgeous!

This is a good video, thank you for sharing

Great and concise explanation making a elusive topic like black hole physics a little bit more understandable for the average layman...

Dr Hossenfelder states the problem very clearly. The Schrodinger equation (which includes the Dirac equation or anything similar) is time-reversible. I will add to this the proposition that modification of the Schrodinger equation is prohibited. I would also suggest that quantum mechanics tends to be more resilient in the matter of reversibility than classical mechanics. If you push a classical railway wagon, then it goes off the rails quite easily thanks to chaotic dynamics, while a quantum wagon tends to bounce back onto the rails. However, we know that as a Black Hole forms and then evaporates, there is absolute destruction of any 1:1 correspondence between initial and final states. So what is happening? A cloud of point vortices is a solution to Euler's equation in two dimensions. If we add some Brownian motion to the vorticity, then we now have a different equation that we are solving, namely a simple form of the Navier-Stokes equation. I said that modification of the Schrodinger equation is forbidden, so we need to think carefully about what we might do in quantum mechanics. What we can do is to add tachyonic Brownian motion. The Schrodinger equation describes an oscillation in one way to travel faster than light, and we can have orthogonal TBM in the other way to travel faster than light. The TBM is apparent during the tripartite interaction of matter, the electromagnetic field and randomness, and is the principal agent of entropy increase when nitrogen tri-iodide is detonated by an alpha particle. Otherwise it is something of a will o' the wisp, and turning TBM into a working computer simulation won't be easy. I want to use Excel VBA to put a simulation of the Dirac equation into every home, so anyone can play around with TBM and similar ideas. So far I have a simulation of an electron in a dipole magnetic field available now (i.e. the Van Allen belt) so you can see how to do object-oriented programming.
