Cosmologist Martin Rees discusses the latest advances in cosmology like the breathtaking images and data from the James Webb Space Telescope-galaxies formed soon after the Big Bang that are larger, earlier, more structured, and more numerous than expected-humanity’s existential risks, including pandemics, biotechnology, climate change, nuclear war, and AI, and “long-tail” risks such as asteroid impact.

Excellent discussion. Love CTT and Martin Rees.
What has always astonished me is how some people are more profoundly intelligent than others, or how some people have more incredible talents than others and so on.
Are you equally astonished by how some animals are more profoundly intelligent than others and his some animals have incredible talents compared to others?
1900s structuralism was very abstract and public schools stopped enriching young minds epistemology of self to better navigate the world and was recruiting for agencies and institutions.
Demands on passive abstract minds with good memorization skills for like army of mathematicians Euclidean thinkers.
But equally filtering out ben Franklin all encompassing intelligence because it tends to be more prideful and wouldve been to competitive
In fact it destroyed the triality of self human dashboard all together with evolutionary mythology
Yes...As a matter of fact, I am...@@kafiruddinmulhiddeen2386

Martin Rees is always wonderful to listen to.
is it possible to build telescopes that see smaller than infrared in early universe?
INSIGHTFUL PROGRAM.
Only half way through but had to express my enthusiasm for this most excellent of interviews.
Our Earth is still growing :)
Martin Rees is a voice of reason and responsibility in the scientific community, we need more like him. All the best.
4:14 MR: yes I mean 1. I don't think what we learned from jwst does anything to diminish our confidence in the Lambda CDM model because it's tells us about how the gas behaves in a universe where the dominant material is dark matter and the behavior of gas is very complicated shock wave and cooling and winds and things and we didn't understand that very well and we're learning about it from jwst because it can look back further into time and see things but I don't think it really weakens our view about the Lambda CDM and just to summarize the situation as I see is it's rather amazing that I think we can trace cosmic history and outline back to when the universe had been expanding for no more than a micro second and at that time it was of all of super nuclear densities and the entire observable universe today would have been compressed to smaller than the solar system why don't I go back still further than a micro second the reason is that that's the era when every particle has about the energy which we can produce in the world biggest accelerators the one in 日内瓦 you want to go back further we lose our foothold in experiment and I think it's accepted by most cosmologists that to answer some of the fundamental questions like why is the universe expanding the way it is why is the shape it is why does it contain the ingredients that we observe dark matter and atoms etc we need to go back much much much further indeed in an idea called the inflation universe we have to go back till the observable universe was squeezed not merely smaller than our solar system but down to the size of a tennis ball that's a huge extrapolation and of course we have lots and lots of ideas about what the physics might be but are battel tested by observations so we have traced things back to a micro second but a lot can happen before that if you think on a log scale so I think this is a great achievement of cosmology in the last 50 years because when I was a student we didn't even know there was a big bang at all and settled in the mid 1960s and as you know things have been filled in not by armchair theoriests but by better and better experiments more powerful telescopes plus incidentally more powerful computer simulation so we can actually do virtual experiments which of course astronomers can never do in the real world. 7:13 ... 8:42 the other thing actually, 2. before we finish with the space telescope is that an equally exciting new development which we're getting from jwst which involves being able to see in the infrared and which is going to be exciting the next few years is um quite different from looking at high red shifts it's looking for planets orbiting other stars one the most exciting things in the last 10 years has been the realization the most of the stars in the sky that we see when we look up are like our sun and are orbited by retinues of planets just like the sun is orbited by the earth and other familiar planets and so we now know that most stars have um a range of planets some rather like the earth some rather like Jupiter and these have been detected indirectly by their shadows as it were when they move in front of the parent star um they're very much fainter of course the stars themselves but these new telescopes will be able to collect enough light that one will see the light from the planet itself to give an example, supposing that you were an alien looking at our solar system then if you were say 100 light years away the sun would look an ordinary star and the earth would look in Carl sers nice phrase like a pale blue dot 10:12
Another point, is when dealing with collective intelligence, the dumbnesses of humanity becomes so clear and breaks individual relationships
greater safety and reduction of existential risks with divine central authority unity, without sacrificing as much liberty and privacy?
Dr Kuhn approaches his enlightenment the way Groucho found vaudeville.
could human interaction with asteroids increase the chance of asteroid collision with earth? a slight deviation of asteroid path might lead to collision on future passes of the asteroid near earth?
AI consciousness when able to operate without programming?
Happy New Year ❤🌟🙏👍😊
greater effectiveness dealing with any climate change under divine central authority unity?
discussionsl like these make me believe that phisicists should avoid commenting on social policy.
Rees is the best!
might quantum computers develop ability to sense external world around it?
Martin is the most handsome octogenarian I’ve ever seen - and he’s smart - good job!👏🏻
would AI taking over human jobs say anything about conscious awareness?
Great talk. Would love to hear Robert Sapolsky on here sometime! His newest book Determined is one of the most interesting ones on the topic of free will (and personal responsibility) I've read in some time. He cites a Closer To Truth video in it, btw!
Rules,! like Sanctions that kills millions
Not one of Martin's best interviews.. Although he seemed somewhat distracted here he always has MY attention..
people work to develop divine central authority to replace some jobs lost to AI?
16:09 “natural ones like covid-19”
Yeah except SARS-CoV-2 hasn’t been found anywhere in nature.
Says you, and yes they have been found in nature and natural hosts include animals such as bats.
No, says science! Open your eyes!
Have they let you out on a day pass from your conspiracy theory echo chamber?
@@artmcteagle bats carry many coronaviruses, but no bat has ever been found to be infected with the SARS-CoV-2 virus.
Quite the impressive library Mr. Rees has.
I'm going mad - there's so many great books i own now, and want to study all of them, but... "sometimes having too many options is as painful as having to few".
The most profound content: Veda, Upanishads, Periphyseon, Plotinus Enneads, Plato, Philosophy as a rite of rebirth.... the thing with the Veda and Plotinus Enneads or Neoplatonism in general is, if you want to grasp it truly, you have to basiaclly know everything.
Whatever your interest or passion, may your expeditions reach your desires, and may it avail mankind.
Folks, we have a big fight today, really, and i don't believe many of you know the scope or have the wits & courage to face it. Things progress and happen very fast today.
Sorry there isn't much of a fight. Your fantasies cannot do anything.
I wish the same for you. I hope you enjoy all the works you are going to read.
Spiral galaxy is one mass rotating at constant velocity. So, anywhere from the center of galaxy one measures the velocity, it will be the same constant velocity. To me, there is no dark energy.
Personally and as far as amateur Philosophy is concerned I never questioned the Big Bang nor the MWBR, that was not the actual problem...but I do question the concept of a beginning to everything! In fact I think the so called most important question in Metaphysics, "why is there something rather then Nothingness?" Is absolutely stupid! You see Nothingness in the absolute sense by definition does not exist, therefore there is nothing to Nothingness...this is to mean, absence MUST always be relative to something that will exist in Spacetime somewhere...either the absence of something that from our Spacetime POV will happen but we are not sure, we call it something potential, or something that already was and ceased to be, but which is forever true that it did exist! Total absence is the absence of absence itself when there is nothing to be absent at all times...and thus a reification of Everything! The only thing that makes sense and that we see everywhere are Fractals, and there is no reason to not suppose logically that the Whole of Reality is a brut fact, much probably circular in its process just like a fractal.
You see in a fractal Size is irrelevant, and so is the notion of before and after...on that regard Penrose is onto something regarding trailing the correct axioms on which to base our Cosmology. His modelling with his Conformal Cyclic Cosmology might be wrong or might be correct but his intuition is definitely in the right place!
A brilliant and beautiful man... And Robert, you're not too shabby either. 😏
Why do you/we just assume that future technology will be “electronic “? How long has electricity been part of human technology? Certainly less than 200 years… this is nothing in human history, especially given the pace of change now… Why not -when we try to imagine a future- recognize that we do not know anything about the technology that will be developed in the future that would make all of our current speculation moot?
The affluent will never accept real sacrifices for the benefit of those they do not know.
Are you saying that the affluent are just like the rest of us, except affluent? Why would you expect anything different? BTW, I know you don't know me, but I need braces and I can't afford them. No doubt it'd be a sacrifice for you to send me the thousands of dollars the orthodontist wants, but I know I'd benefit if you did.
The affluent have more to give, and therefore more to lose.@@blobusus
Most of all our youth needs EMPHASIZED goals ,task & ed. This new paradigm is not an evolutionary line of thought .We mapped this without accounting for the human dashboard so
Its more or renisanced line of thought due to computation, simulations idealogical influences.
Young minds think inside out ,as if everything interesting occurs in critical extreme states.
That word, “dashboard”, triggers flashbacks.
@@longcastle4863 Haha 😄 😆 🤣
I struggle to find the best word there.
When I use epistemology of self it doesn't really convey the data transfer & exchange with our instruments and detectors used on the universe.
We removed the human dashboard and confused all our many different notions of time. We've been mystified by physical prescriptions for so long pushing complexity down upon us so long that we created to many cults within cults. Lol
By this shall all men will know that you are my disciples, if you have love one for another. - John 13:3
Like we’re supposed to believe Christian’s are preaching love these days instead of hate. When all we see is hate against the LGBTQ communities, hate against Jews, hate against Muslims and Asians and people of color. Hate, even, against democracy itself, as Christians claim Donald Trump-would be authoritarian and dictator-as their “Chosen One”. If it is true that by their fruits you shall know them, then Christians side, obviously. with the Prince of Hate. They’re just too cowardly or too ashamed to admit it.
There's always gotta be that one bible thumper in the comments.
Mr Rees shows universe Though his determinist vision. But Universe are underterminable nothing now in Universe is predict. Mr. Rees believes in Universe as computer program but It is not How figuret out Universe in order by unpredictable conscieusness keep out Universe reality.

You should worry far less about Peter Thiel and start worrying far more about what is now obvious to all sane people is a completely irrational & unhinged Democrat Party
I would say exactly about the same thing about the GOP and their cult leader.
@notanemoprog @artmcteagle
Yes! to both of you. Both sides are corrupt. We all know it. Don't except it!
You have allowed yourself to be propagandized to the loss of your own opinions. You need to find your self out of that rabbit hole.
