Fantastic talk, Sabine Hossenfelder has introduced physics and concepts in digestible bits for folks like myself trying to learn a little bit more every day

Clear presentation of somewhat difficult to comprehend ideas. Informative and educational in an interesting way. Gotta love this intelligent woman.

Thank you Dr. Hossenfelder for taking time out of your busy schedule to deliver this lecture. I’ve learned some great facts and ideas from your videos.

11:26 I find the idea of a thinking universe on a large scale interesting and I hadn't known before that physicists have started to think about it. However, what I thought she would say, and this would have appeared rather self-evident to me, is that we know already that the universe can think through us. This wouldn't mean that the thinking is everywhere (in the sense of the idea that the whole universe can think), but as Sabine said herself we are part of the same universe, so apparently at least parts of it can think? So the question for me would be whether there is, in addition to the thinking that the universe already does, further thinking: among galaxies, tiny wormholes, etc.

She's wonderful! Smart, humorous, and good at teaching. Follow her science news channel. Oh, and she also creates music. 🙂

When I have heard her before she seemed to lack imagination. Now I see it's just that her imagination is strongly tempered by precise logical thought. That is the mark of a great mind, my respect for her has increased significantly. It is an annoying aspect of a scientific world dominated by sensors, people who do not delve into the subconscious as much, that these insights are frowned upon. I hope as her standing increases she becomes more free to express them.

Well she has nailed her colours to the mast of superdeterminism.

So good to have this content available, science is cool.

Physics can discover the laws of our universe and how we can use them. That is the limit of physics. It can not explain what happened before the big bang. It can not explain how psychics can communicate with the dead. It can not explain how it is that some people can see the future. Physics can not develop equations to explain these kinds of things. Sabine Hossenfelder makes physics so interesting and explains things so well. I think she's the best!

Interesting to watch you from another perspective. I watch your youtube channel religiously! And watched you with Penrose and others in discussions. I always learn something and love your, yes, strange humor!

The world needs more Sabine!

I am happy to inform you that Sabine exists in my subjective experience of the universe.

It is always a pleasure to listen to Sabine Hossenfelder's thoughts. They are easy to grasp and to say in her words 'ascientific', at least for me... I have no evidence against nor do I have evidence supporting the idea behind her thoughts.

Love her honesty

The best science communicator of our age? It is rare to explain the most complex ideas in a way that is completely understandable.

Totally absorbing. Well thought out....

@@erickmorales4312 I generally agree with you; I am an agnostic and I fully realize that using the word God will be controversial to some. Personally I like the view (attributed to Einstein) that there is a creator/god, who is not concerned about the day-to-day existence of humans.

In a way, she is giving motivation. Just like how dark humor can be therapeutic for a individual; being able to be self aware enough to realize when certain things get off track and it can motivate you/anyone to attempt to look at these things and try and find a new perspective/approach to solve a problem. The best inventors, philosophers, artists seem to be able to be comfortable with facing things and learning to harness the ability of how you observe things as a tool and through perspective experimenting, you can sometimes stumble upon new methods/manner's on how to solve problems in ways that others didn't notice/see/or understand. (Just like how Einstein had the ability to get lost in hypothetical thought and imagine different perspectives and then it stumbled upon his path towards learning about light/energy/physics etc.) That came from Einstein taking a category that previously was in a state of limbo, but he was willing to look at it and see if he could find anything else out about it. So if you get demotivated, or down, try and remember that even things we think we fully understand; have the total possibility that you can look at it/observe it in a new light that others haven't and totally find a new layer of complexity or depth to a topic. So even if we are faced with a lot of difficult situations, roadblock's, the best thing is the universe is full of amazing intracity so the chance of further understanding the world around us is profoundly possible and to me that's very motivational and Nature itself some how seems to have a way of always keeping that inner child like curiosity alive with-in my Life.

Yes, that guy again 😆 Sabine must be so proud he was German

She’s so cute how she’s nervous 😊 I hear it in her voice since I had to also do a lecture and had the same “chopped” voice lol

I don’t know if it’s the same experience with others. Being taught and given empirical meaning to what’s being taught, gives me liking and an opportunity to better interpret “stuff” and even maybe make advancement on them. I’m usually lost if I cannot pair what is taught with empirical meaning. This is why I like Sabine. She dangles these two so well. In undergraduate physics, I didn’t understand geometrical meanings of the cones in special relativity. And here she opens up so well to it.

Sabine, you rock girl! 👍

Excellent talk. Thanks Sabine. > I am uncertain if "Can the universe think?" is the right question as it implies a certain human characteristic. I am more toward "Aware" but in an abstract non human way. All information across the universe being directly connected in the now moment, and that universal connection of information as a combined set forms a kind of non human knowledge. To use a human analogy, the universe knows the entirety of itself in any now moment. This is not human like though.

Newcastle is a bonnie city. It used to be part of Scotland and for a time it was the capitol of Scotland. Well. I do not believe in the multiverse and I think the theory was born out of arrogance and fear. The universe is vast and incomprehensible and we belittle the universe by stating there are many. This makes us feel safe. My theory is that there is some kind of subconscious interaction between the brain and the universe and that computers are evolving our brains. If the universe was a gigantic brain it would send and receive messages through thought which is instantaneous and faster than the speed of light. Obviously if it is the universe that is thinking it will not be subject to the rules of time and space as we perceive them.🌱

13:00: "That they have quantum properties means among other things that they can be in two places at the same time. We also know that those particles have masses, and mass generates a gravitational pull, which brings up the question: if you have a particle that's in two places at the same time, where does the gravitational pull go?" - Interesting point that I've not thought about before. The obvious answer would be that gravity behaves like the particle's electric charge. If a charged particle interacts with another charged particle in some observable way, then that constitutes an observation and the wave function collapses; the particle is no longer in two places at once (or rather, the amplitude of its probability distribution no longer has two peaks at different points in space). So with gravity: if the particle exchanges a graviton with another particle, then again the wave function collapses. But it's a long time since I studied quantum mechanics (and not very successfully even then), so it's probably not that at all.

Sabine deserves better lighting

Wow! That was amazing!

13:26 that means spacetime isn't the most basic property, information is, if two particles are in the same space that only means they are strongly correlated in a information point of view, and the biggest correlation between specific particles is what creates gravity, not the spacetime. Which is why theories can't be reconciled. one of them is basically missing "hidden variables". With general relativity its too easy to confuse an useful abstraction with the real thing itself. The real thing is information, not the space that information represents. Information can be duplicated, and information don't occupy space, but information can correlate with itself, that creates Shannon entropy, and that creates the effects of "gravity". Yes, I subscribe to the information-theoretic foundations of physics (for obvious reasons, I'm a computing scientist).

Shared by free so wonderful!

The arrow of time points forward in time because of the wave function collapse. Because causality has a speed limit every point in space sees itself as the closest to the present moment. When we look out into the universe, we see the past which is made of particles (GR). When we try to look at smaller and smaller sizes and distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears when we start looking into the future of that particle. It is a probability wave because the future is probabilistic. Wave function collapse happens when we bring a particle into the present/past. GR is making measurements in the predictable past. QM is trying to make measurements of the probabilistic future.

This talk reminds me of the book "Flatland".

Ah, Sabine of the Dry Humor. A jewel in every sense. I'm subscribed on YT, but found this on my own. Lucky.

Physics might be the most powerful tool we have to make sense of our own existence but it is not powerful enough. Even if physics came up with a perfectly complete set of theories that precisely describe existence and for which no violations could be found we would still be asking "why universe is that way?" The answer to that question seems to be important for making sense of existence yet it is a question which no answer could completely satisfy.

This point is very interesting: that we always see everything as it was in the past because of finet speed of light. We can never know the present, no matter how tiny a fraction of second the time lag is. Reality we experience is always in the past, never in the present. Raises interesting philosophical questions.

Interesting and thoughtful! I think what I heard you imply is that since the concept of a thinking universe is compatible with what we know, though there's no evidence , one might say it takes faith to believe in it. Personally, I can't argue against having faith in that which is compatible yet unprovable. So, why not faith in a creator outside the universe?

Dear Sabine (I hope you read the comments), I like your work a lot! I would appreciate if you would also tell people that what you call "compatible" indeed means that our philosophical speculations are at least 50% about our own theories and not about what we call "reality". In my eyes all our theories are "compatible theories". As the observer problem clearly shows, the reality itself is and will always be beyond our knowledge. I think the works of Donald Hoffman show this very impressively.

Now I know the difference between scientific, unscientific and ascientific. Thankyou Sabine.

I find such subject matters intriguing sadly there is no one I know to have conversations with about such deep-thinking subjects in person.

I've wondered if the universe was like a brain, with all those interconnecting filaments, made of galaxies, that look like the neural networks of a brain. Then I realized, that everything my consciousness interacts with comes from my brain, and when I interact with my environment, I'm not really interacting with it, but with a copy of my environment that lives in my brain. I'm probably an imperfect copier, who copies the universe and tries to fit it into my brain. Then we make A.I. and we make copies of copies of the universe, and so on and so forth, like a fractal or an infinite mirror.

Go Sabine!!!

There are a lot of parts of the universe who show no signs of logical thinking. But I agree. If even one human can think then the Universe can as well. The only debate will be if the human is the part of the Universe that can think, or there are bigger (or smaller) structures capable of thinking.

surprisingly, that's kinda what I thought when I was a kid, I "kid" you not 😅 essentially, that we exist inside the brain of one enormous giant and conversely have little beings residing inside our brain which they consider their universe. and that would go one infinitely.

Just because a system would have an unbearably low frequency for our mortal standards, doesn't mean it can't think, just that if it does the timescales involved are much larger. Unless the expansion of the universe rules this out someway I guess?

There could be an Absolute Time measured not by light, but by entropy. The Universe is 13 billion years old. Everyone in the Universe agrees with this value, and also that the rate of increase of entropy in the Universe is the same for all observers. This rate of increase in entropy could be used as a unit of time.

So smart
