Carlo is a really good guy because at his center, he is a teacher and a story teller. The story he tells here of Dante Alighieri and the Inferno, Purgatorio, Paradiso is interesting for a hidden reason. Dante wrote it in a dialect of Italian that unified Italy. In a way, that is what Carlo himself is doing in his description of the white holes and black holes. We also see this basic personality in Einstein himself. Albert, at heart was apparently a humble person as well as an intrepid, brave explorer. This type of person is easily the kind we gravitate to.

Collectively the three parts of the Dante story is the Divine Comedy. Written in 1320, it helped start the Renaissance. The last line in English is concerned with how we emerge to see the stars again. Humorously, that is how Carlo ends his journey through the black hole, then out the the white hole To Eventually SEE THE STARS AGAIN!. (QUE BELLA.)

I love how Carlo explains everything in a way that basically everyone can understand. He paints a picture that everyone can imagine. He gives everyone the chance to wonder along with him and his colleagues. That takes an extraordinary amount of talent I think. We don't always have the ability to comprehend the extreme mathematical complexities of the studies of astrophysics. But we are so privileged to get to learn and reflect on the wonders alongside those that do comprehend and are able to share it. Thank you to all who work so hard to make that possible. This is such an exciting time to live in. I can't wait to learn more

"everyone can understand". Same way Flat Earth can be explained: "we don't fall when stand upright, hence cannot be with inclination, hence flat.". My point is that 5:57 optical effect was not explained, if some light bends, then some light coming to us bends away. Why do we see more of light from this narrow circle?

21:00 - More specifically, it was meant to illustrate that Human Intellect or Reason (represented by Virgil) could only go so far and couldn't be used to understand divine redemption or paradise. That has to be one of my favorite stories ever. So much philosophy is crammed into that single poem (Inferno) that it's practically bursting at the seams.

You describe the two parts of physics (and all sciences): experimental (of giant experiments) and theoretical (of thought experiments). Both are essential, neither is less important. We've had both, from as long back as we have records of science. Some experiments in experimental physics are "giant" because they must utilize massive amounts of energy (e.g. to generate the Higgs boson) or massive amounts of space to detect infinitesimally weak gravitational waves. To work, they must be "giant".

The physics - established and speculative continuation of that - is fascinating. But the real message for the public understanding of science is what Carlo discussed in the last few minutes - the central place of the imagination, and emotional and intellectual response to the imagined, in the development of science. In wrestling with a problem, possible answers (not all right!) come in response to the 'simple' question: 'What if .... ' What indeed!

In University I was studying as a double major in Math and Physics but I found I needed to eat regular and I figured so would my future wife and children so I pursued a professional career in a different field. What I found as I progressed in my career was that if I approached an endeavour from the same prospective as my competitors my success rate would be average. Because they and I were all trained to look at the problems we would face in a particular fashion. So what I decided to do was to not look at the problems from the the normal set of rules exclusively, I would look at the issue as I knew my competitors would be doing, but I would always try to look at them from an entirely different and sometimes radical approach and see if that took me to the desired end. It didn't always work out but when it did the results achieved were sometimes far more efficient and personally satisfying. There are always alternative approaches to any problem and if you see a whole herd of anything banging their heads against a wall maybe you should look for a way around the wall, or over the wall, or under the wall, or avoiding the wall entirely especially if you are adverse to headaches.My alternative journey always begins with..."What If"

Exactly ! When almost through college I took a "summer" job and the department had a major process issue and my direct boss was tasked with providing an outline so everyone could get to work fixing it and told me to do a rough outline. As I had no experience with the system I approached it like a College Paper. I took everything home and when I turned in my outline on Monday I expected to hear a lot of criticism for going too far before I involled others. There was a history of how the company got there as well as pointing out the wrong decision 2 years earlier that moved them into this dead end process. I pointed out that any of the fixes purposed over the last year would still leave a system that wasn't scalable without additional fixes ($$$) over time. On Tuesday Afternoon they called a meeting and using blowup of my outline they explained that they were reversing the decision of two years earlier and immediately ( at a high cost) changing the system completely. It seems like the VP had opposed that decision at the time ( he wasn't VP at the time) and when showed the outline decided there was no reason to spend any time patching the system. I had a job . . . .

The struggle is real, many an interesting lecture ruined by clacking and other mouth noises.

I have a problem when any scientist talks about matters we do not fundamentally know, as if we do know. It really erks me when he said a little bit less than half way through, that all he had just described was based on stuff we know very very well. It's not. It's not even that we don't know a lot of it. Everything beyond the event horizon we know literally nothing. So the geometry inside we know literally nothing. Whether or not it has a singularity we know nothing. How objects behave inside, we know nothing. I think the most ludicrous thing he suggested is that we know instead of a singularity, it's actually just the collapsed star all ostensibly safe and sound, the same way it was the moment of collapse. This is most ludicrous because a, we fundamentally don't know, and b, there is absolutely no math that even remotely suggests that that matters from the collapsed star just stays the same, stays bound together, the same size it was the moment of collapse. If all of this is based on Einstein's theories and those mathematics, the math says it's not even possible for that matter to stay together. You get infinities when you do the math. When you calculate the density of an object massive enough to force a transformation into a black hole, the only thing that is ever on the other side of that equal sign is infinity. We don't know why that is. Most people say it's because there is something we are missing because we can't combine perfectly, relativity with QM. They say it's because we need a theory of everything. Personally I think QM and relativity are actually already the whole picture and they can't be put together in order to illuminate that which is still hidden to us by them remaining separate - because that which is still hidden is FUNDAMENTALLY unknowable. I think what happens inside a black hole, is fundamentally unknowable. The Heisenberg Uncertainty Principle says both the momentum and position of a system are unknowable fully simultaneously. Instead of having to specifically state momentum and position, I think it is reasonable enough to simply say that you cannot know all the information about a system at the same time. Now if we investigate further into the specifics of the principle, when we use examples, we realize something stranger that I honestly think most scientists don't fully come to terms with or they just disregard it at a relic of the mathematics. When you know the position of a particle, it's momentum ceases to exist. If you know the position, that means you have locked it down, into a single frame so to speak, like taking a slice out of time and defining its position as it is seen to be in that slice. But if you take a slice out of time, the object whose position you are defining stops moving through space, because you can't move through space without also moving through time, so if you have stopped moving through time you inexorably stop moving through space. If you aren't moving through space, you don't have momentum. That is just a physical fact of the universe. If you have stopped moving, there ceases to be information that defines your momentum that can then be used to calculate it. The information about your momentum literally, fundamentally, ceases to exist. Likewise when you try to define position when you have momentum, you ultimately fail because if something is continuously in motion it's position is always changing, and a single reference frame for it's position cannot be defined. The information itself does not exist because it has no position, only a change in position. You can define and calculate the change in its position, but not it's exact position. The only way you can do that is if you take a slice of time and say this is it's definitive position. But alas, as we just discussed, when you do that, the information about it's momentum ceases to exist. So what the Heisenberg Uncertainty Principle ultimately says is that you cannot fully know everything about a system because some of the information itself about that system, does not exist to be known. I believe this is why we will ultimately never know what happens inside a black hole. Sir Roger Penrose actually proved that Einstein's theory naturally, generically, lead to the creation of singularities in all solutions, which includes those pertaining to black holes. So again, at least as far as the math shows, singularities do exist at the center of black holes. Personally, I think the reason we get the information paradox, the reason we get infinities when we calculate the density of black holes, is because at the singularity, the spot where there is infinite density, there is a rip. This rip is a literal tear in spacetime, and on the other side of that rip is the Inflation field, the true vacuum from which our false vacuum universe inflated. This is why all the original information that false into a black hole literally ceases to exist in our universe, because it is dragged outside of it and spit into the inflaton field where i cant even begin to contemplate what happens to it. I also think that the reason this hole, on the other side of which is a true vacuum, doesn't instantly grow the moment it's created and lead to vacuum decay is the immense gravity that's keeping it confined. Which is paradoxical because it is the immense gravity that creates the rip in the first place. Then as the black hole evaporates, the density stays infinite until the finale moment of evaporation, and then when it disappears and the immense gravity lets up - since it was gravity thst both created the hole and kept it from getting bigger - the tear in spacetime simply seals shut.

This really gets better towards the middle and especially the end. 52:24 Science as Mind Travel 56:49 The point about changing perspective 57:39 What do we keep with us, and what do we leave behind when making the next jump (- leaving behind the stage of space and time).

Work of Art Carlo! Wonderful. Thanks.

There's a subtle concept that he sort of missed in his explanation of the ship slowing down as it approached the black hole, although perhaps not too important just to make his point. Yes, you can explain it as time dilation, as he says, but the interesting question is why are we seeing the ship's apparent "movement "slowing, something that we would NOT see if the same ship were accelerating toward the speed of light using its own engines cutting across our field of view. In the black hole example, we are talking about gravitational time dilation. In the second example we're talking about relativistic (kinematic) time dilation. In the black hole example, it would appear as though time is passing more slowly for the ship as it approaches the event horizon. The ship would seem to slow down and never quite reach the event horizon, effectively appearing to 'freeze' due to the extreme time dilation effects at this boundary. In the example where the ship is accelerating under its own power, the situation is different. Special relativity, which governs this scenario, dictates that time dilation would occur relative to the ship's frame of reference. To an observer on board the ship, time would seem to pass normally. However, from the perspective of an external observer (such as someone watching the ship fly by), the ship would not appear to slow down. Instead, it would be seen moving at high speeds, as expected. The time dilation in this case affects measurements of time and length within the ship's frame of reference, not the speed at which the ship is observed to move.

Yeah I can't square that part either.

It seems the analogy is that DM is planck mass WH out of a BH, much like a photon is a particle out of an electron quantum leap....following along his mind travels...so Carlo is working on an experiment to detect this. Interesting question to answer.Where does an Electron go in between Quantum Leaps. The White Hole is that type of phenomenon

In his "remnant/ white hole" model, the evaporation slows down near the end and then it takes a really long time for that remnant to disappear.

@@dimitrispapadimitriou5622 So does DM appear before Barionic matter or after....the egg or the chicken....or does DM appear at the Galactic edge by virtue of going through and beyond a Black Hole , coming out as a White Hole through an entangled wormhole from a BH..... interesting concept though....the proof is in the pudding

We use the word evaporate, but remember that, nothing evaporates into nothing. A black hole evaporates into something.

1 sec in black hole = 1 day on Earth. 1 min in black hole = 60 days on Earth. 10 mins in black hole = 600 days on Earth. 1 hour in black hole = 3,600 days on Earth (approx 10 years). 24 hours in black hole = approx 240 years give or take. 30 days in black hole = 7,200 years. 12 months (approx) in black hole = 86,400 years.

That was fascinating. I hope he gets his detector!

I really get tired by people proselytizing their culture in an unrelated setting. Dante this, Dante that. Dude, just get to the point.

That was really interesting

If you measure anything with a quantized tool (math) your outcome will naturally be quantized. What if there is a type of math that isn't quantized? What if there is a seemless, gapless, whole stream used to measure? Afterall , numbers have spaces without function between them 1gap2gap3gap etc.

There’s this brilliant new age theory about something called fractions and decimals. It’s crazy, I know, but this theory posits that there’s actually something BETWEEN integers, can you believe it?! 😱 What will they think of next?

Yes, and there are gaps between the integers and fractions etc, no matter how small you slice it Thats why numbers are quantized. Open your preception of reality a bit more and see if you can come up with something different.

I'm sure he knows much more than me, but one small semantic correction: when you experience time dilation with the messages near the black hole mass, you are not seeing the future, you are travelling relatively slower through time. You are always in the present and feel normal, but when you return to earth many thousands of years will have passed more than according to your frame of reference.

Fantastic! My reflections are: 1. General relativity tells us that the experience of time is entirely relative. 2. Quantum theory tells us that our experience of matter is also relative. 3. Some theories suggest that the force of gravity appears weak because it is mediated across many dimensions. 4. Imagining that the universe is, to all intents and purposes, eternal and self-regenerating, could “dark matter” therefore simply be the legacy gravitational signal of matter which has since “transcended” to another dimension via black ->> white holes?

Great video, but at the 25:45 mark you say we get to the “individual grains of space”. Maybe I’m missing something but if the general understanding of what is meant by ‘space’ is that it describes an area or place that it is empty, I do not understand what is meant by ‘individual grains of space’. Can you please explain? Thanks.

46:00 this way it would make sense for galaxies as matter going from white hole cloud to black hole center.. might be this way? could galaxy be considered a space itself, something like cosmos bubble then? and for bigbang.. what happens if we run around a dimension? could it have edge? since its most probably single self interacting entity.. what would happen if we go over edge of 4th dimension? does it bounce, or has it a counterpart out of phase that will switch at the edge? or.. will you get wehere you started..

Hard to listen due to the mic picking up tons of extra noise. (Plastic scratching, fabric rustling, air/wind/breathing whooshes.

Awesome 👏👏👏

Is it possible that some of the visible light that whips around a black hole is future light? Even if it’s only by a few seconds/months/years?

Beautiful

Please give us the Q&A session

Professore lei è unico! È evidente la fatica che fa per "dumb it down for us"! Immagino sia come un padre che spiega analisi matematica a un bambino di 5 mesi...

Great ASMR presentation :P

Love your explanations thank you for making it accessable to a broader audience. One tiny bit at 6:45 u say the orbit of the Moon is bigger than the Sun is that really true?

Magistrale Carlo

@6:43 i know it's not the point of this talk at all, but is the orbit of the moon really larger than the sun? as far as i know for the moon's orbit, r=~385k km, and the sun is r=~700k km. or did he not say this?

I have a question; if a black hole is a sphere, how it is also long with a seemingly never-ending tube that is longer the older the black hole is? The picture being described at around 16:30 doesn't exactly make sense to me if a black hole is spherical. Is this just a depiction of what us as humans would "see" if inside a black hole, and it's not actually the case?

Can someone please explain the blue shifting toward us at around 10 minutes? I get the Doppler type red shift of the rock or clock falling in to the hole but not so much the blue shift of earths messages toward us the way he described them.

What kind of matter could survive the additional energy ?

This takes me back to the first time I heard about white Holes before Hawkin tried the maths for himself, must revisit Nasiem Harrameins work again
