Unravelling the mysteries and origins of the Universe remains one of the biggest questions in physics. Drawing upon decades of research and observation, the scientific consensus based on current evidence supports the theory of a single Big Bang event that led to the formation of the universe as we observe it today.
While alternative evolutionary models such as bouncing and cyclic universes are undoubtedly intriguing, they lack the observational support and experimental validation that the Big Bang theory enjoys.
From the Cosmic Microwave Background radiation, to the large-scale structure of the universe, to the relative abundance of light elements, the Big Bang theory remains unquestioned.
But new areas of research continue to develop, such as the study of dust and its contribution to astrophysical research, facilitating further understanding of the early universe and its evolution. As a leading expert in the field, Brian effortlessly navigates through the complex and fascinating science behind our universe and its conception.
Brian Keating is a Chancellor’s Distinguished Professor of physics at the Center for Astrophysics & Space Sciences (CASS) in the Department of Physics at the University of California, San Diego. He is a public speaker, inventor, and an expert in the study of the universe’s oldest light, the cosmic microwave background (CMB), using it to learn about the origin and evolution of the universe.

This talk was one of the highlights of my professional life! Thank you to the outstanding demonstration team, the organizers, and incomparable staff of the Royal Institution for allowing me the honor of giving this Discourse. I hope to be back on your hallowed grounds someday!
The accelerating expansion of the universe may not be true. what do you think of this article? : Evidence for anisotropy of cosmic acceleration, arXiv:1808.04597, A&A Volume 631, November 2019
Thanks for coming in, Dr Keating, it was a pleasure to host you.
Congratulations Dr. K!!
Thank you so much for sharing your knowledge Dr. Keating. Incredible!
Great venue!
I've never met anybody like you, Brian. Your ability to explain cosmology and astrophysics with such clarity and passion is truly next level. Congrats on yet another career milestone.
One of the best presentations i have seen during recent years at RI. As a person who is following you Mr. Keating on your youtube chanel i knew you are going to deliver... but this was truly an outstanding presentation well beyond any expectations. Congratulations! Happy for you to be there! Well deserved for all the years of your hard work :)
Thank you for giving an excellent lecture with clear voice and clear logic.
To me, Paul Davis' remarks are quite memorable.
"Multiverse explanations are reminiscent of theological discussions.. invoking an infinity of unseen universes to explain the features of the one we do see is just like invoking an unseen Creator. The multiverse theory may be dressed up in scientific language, but it requires the same leap of faith."
That was fabulous. Your delivery was so engaging. It was a real joy to see you lecturing in such an esteemed theatre. Bravo.
Once again Dr. Keating I am amazed at how well you can break down complex ideas and make it engaging for the average viewer to understand!
This was a brilliant talk by Brian and the jokes were not bad too. It answered a few things I had a partial grasp on so I shall return to this one again and again. He weaved the story from Aristotle through Maxwell, Einstein very neatly
Did he really pack all of that into one hour? Shame no Q&A, but he didn't waste his chance. Delivery was as always impeccable
Awesome lecture! Dr. K crushing it as always 🙌
🙏
you look really well Dr Keating, i was so pleased for you, appearing at the Ri. well done oh and great lecture. but no Einstein finger puppet?
Awesome! I was in the UK last week and had the thrill of attending a lecture at RI and visit the museum. I understand your excitement about the place. Fantastic presentation.
I was originally drawn towards RI presentations as a great source of education and still rely on it to expand my knowledge to some extent today. Although nowadays there seems to be too many talks summarising the evolution of the universe, serving as an opportunity for aspiring communicators to test their mettle at the RI. Please don't interpret this as a complaint because there can never be enough communicators of science in the world as far as I'm concerned and the RI is a great place to foster the community but I rarely learn anything new from RI talks any more. However, your presentation stands out as an exception, implementing many of the great ideas discussed in recent years on your show with the smartest thinkers in physics. But most excitingly, I learned something that I've waited on for a long time, the next phase in the follow up to your amazing BICEP2 experiment! I was deeply inspired by your original endeavours and have always hoped that the experiment would get the follow up that it deserves, thanks for this update! Your presentation was one of the most passionately charged I've seen in many years, no doubt capturing the imagination of many young viewers. Well done Dr Keating, I'd call this a home run.
great great talk! WOW. I see a Nobel prize in Brian’s future
Appreciate the clarifications of the leading theories and hypotheses in the area of bleeding edge physics (cosmology).
Thank you Dr. Keating for such an enjoyable lecture!
Hi Brian. Brilliant lecture. Thanks so much. In the past, Ive dropped in and out of episodes on your RUclips channel, with slighty mixed views (get more people on who are not trying to push their latest book)
But I thought you amazinly excelled yourself. Such a brilliant lecture, oozing with passion. Thank you so very much. EDIT: Forgot to mention it was one of the best RI lectures I've seen (and I watch them all! ). Shalom.
Wow that is so wonderful to hear!
Watched the first few minutes by now, I am watching the Prince of presentation 😊 well done!
wow ok brain blown
this was absolutely fantastic.. i loved all the demonstrations
i prolly only got about a quarter of it 😬 I'm going to watch it again every six months.. to learn more but also to see what changes over time
One alternative point of view and an entertaining and easy-to-understand book about creation, evolution, and the Big Bang debate is Axis of Beginning.
Hi @DrBrianKeating what a wonderful talk. I would love to be present someday at one of your lectures!
Captivating lecture! Highly informative and entertaining!
Really good delivery.
When is the next live lecture and where? Im crawling to the finish of my doctorate and there are a couple of people, including yourself, who I find incredibly inspiring to listen to. Would love to see a live lecture and shake your hand in gratitude.
I have learned much from Professor Keating! ^.^
❤
Thank you . very lovely.
Great lecturer! And brilliant lecture. I loved it and learned a lot. Thank you. ❤️👍
I feel like this talk could be much much longer, very interesting stuff and wellspoken speaker!! Supereasy to listen and easy to get drawn in on the subject.Thanks to Brian for this!
Phenomenal job, Brian!
Excellent👏
Insightful and inspiring. Awaiting the results and potential discoveries this research may uncover.
I'm glad that Brian is a scientist that doesn't afraid to put a Genesis into that lecture with so much respect for both religion and science. I really love his approach on searching not even for answers but for proper questions that first need to be asked. Great lecture!
As always, your lectures are also intriguing and informative .
Very entertaining as well.
Thank you
Great discourse Brian, thank you.
Good job five stars
great lecture...one of the best
Wow, Brian, Man ... Good Work, Great Talk.
I live in Argentina and we follow the laws of an expanding universe, because inflation never stops...
Amazing talk, amazing experimemt, all the best.
❤
Brilliant, intriguing, informative
Most Grateful.
💜
Great performance waww, go go Brain ❤
Great talk!!
Through the power of buying 2 of them
Amazing. I don't know how I will feel if these B-mode polarizations are found (or not). Either way it will be profound. I remember when "dark energy" was discovered and being dumbfounded that the universe will be infinite. That was one half of the question. The ending. This is the beginning question. Can't wait for the results.
Ok.. we don't know why it's accelerating, the expansion... but my question... what would it take to stop this ? Hypothetical, i mean... what phenomenon could actually stop it?
A wonderful talk, but did I miss the part that explained what happened 4 days before the Big Bang?
Great talk Brian
re Malus Law; most of use viewed this effect through an LED display. Is the effect of Malus' Law apparent when viewed through a screen of LEDs? I think earlier in the talk you mentioned that the light from LEDs is polarised. Would this over-ride the polarising effect of the yellow/blue spots?
Excellent.
I really enjoyed that! Thanks!
Nice one Brian!
Is conciousness related to the Cosmic Background Radiation ??
I do not understand why skipping centuries of development from Greek straight to Newton, as if there is nothing in between !!!
Perfectly Timed.
Fantastic as usual 👏🏻
🙏♥️ amazing!!!!!! Thank you!!!!!
Well done Dr. Keating!
This classroom is notoriously prideful. I would propose a humility pass to talks given. As a scientist I see the value of this talk but in my field we need to take this with humble pills. Swagger will set us back, just follow the data and be open to possibilities never overly confident in your eliminations.
Ok i made a comment like a minute before the end of the talk, questioning the swagger you were on about lol, then he mentioned it haha
But I'm curious still, why do you think "Swagger" will set us back, and what do you mean by a a "humility pass" and a "notoriously prideful classroom"???? I don't quite follow
I would suggest that "swagger" involves a confident acceptance that all hypotheses initially are potentially valid but, importantly, without precious adherence to any which have no evidential support.
I see no arrogance here, and I don't see Keating making grand statements of his own work, instead having pride in centuries of successful discovery and the search for truth made by generations of scientists before him. Being a confident orator doesn't make someone prideful (of oneself) or arrogant.
Great lecture!! 👏👏
The light experiment was cool never realized that what would cause that optical illusion, also moved my head with the one experiment and re-pinched a nerve in my neck which wasnt cool XD
What a tie!!!
In the slide depicting the “Popper status,” Inflation theory is designated as non falsifiable, while the Scalar field is. If the new experiment fails to detect CMB polarisation, that is, no degree size curling to be seen in the data, then, the result points to lack of evidence for a burst of gravitational waves during Inflation. How do you imagine cosmology from there on? Wouldn’t this result disprove the current version of inflation?
Sweet RUclips win two favorite channels as one .
I had no idea that Bruce Campbell moonlighted as a cosmologist.
🔥👌
Dr Keating & his friend Eric Weinstein are two of my favorite conversationalists.
God Speed on BICEP 2!
29:55 except we literally cannot say that, we are the only known form of life. For all we know there are a billion different combinations of the cosmological constants etc that can make life, we think the set of factors we have are special, but they might not be. They might just be the ones we got, and since they do not change, the atoms and molecules did what they could in the universe they had. They can't pretend they have a different universe, it's just this one, that's it. no others. The settings of the universe aren't interesting, what's intersting is that life evolves under any settings at all.
Who’s better, Einstein or Newton?
BICEP2 GO!
Here is my hero Brian. Sorry Sabine will get mad at you again
42:00 - 😂
Great talk, a wee thought though,, if the further away we look the universe is expanding faster and faster does this not mean that the expansion was faster whilst the universe was younger. Seams logical unless I'm missing something.
The spectra of the older, more distant galaxies aren't as red-shifted as expected, indicating that we were moving apart more _slowly_ in the distant past. (I had to look that up - it's a great question!)
@@ftumschkI can get my head round that the red shift isn't as much as expected showing a slower rate of expansion. Thanks for clearing my mind.👍
Why is the RI collaborating with PragerU?
Like trying to measure a Duluhan's neck while he still alive?
Great presentation,
(but on one unrelated point, I beg to differ. There's _no_ comparison between wikipedia and The Encyclopedia Britannica, and wikipedia is NOT the online 'version' or 'edition' of that great set. An innocent mistake, but it bears repeating. If you care about it at all, read on. Originally a different comment, but I copied, then deleted it, and pasted it in here, because I actually have an opinion on the Britannica itself):
READING IS FUNDAMENTAL!!!
He had to pilfer one!!! I have the complete set of the Britannica; The first printing of the first _edition_ that totally revamped the index to comprehensively organize subject matter in such a way that _finding_ what you want didn't require knowledge of the 'alphabetical order' of topics _related_ to each main entry. True, with that set, I'm 'locked into' the 1982 'knowledge base', but the indexing scheme is so well designed that updating your research to the current state of the art is actually made _easier_ because of how the core of the hardback set is presented. Computers and artificial intelligence are fantastic, but there's a definite advantage to also using just the _index_ of that edition, as it helps you drill down deeper in a manner suggested by the index. It really is quite a bit like having an expert nearby who you can tap on the shoulder and ask "What might I be missing? What other topics might I include?"
READING IS FUNDAMENTAL!!!
Hang on...we dont know what Energy is or how the concept of Entropy harnesses it...answer what Energy is, we know how to equate it, track it, but what is it!
😅
Brian Keating is One of the most interesting physicists and experimental physicists today who push the idea of the multiverse forward and I can only say that we are right, the multiverse is the reality of all realities .I support his efforts to prove it experimentally. because reality is fractal final spiral and goes in a circle
Is it still one god or one god per universe?
Would seem it would depend on the beliefs of those asking from within a particular universe.
???
4 minutes of ads in the first 10 minutes
Not fun😮
32°C in the room? What? can't they even afford proper heat-pumps or do they simply like it hot??
The building is 200 years old which, coincidentally, is also the last time it was over 30°C in London.
@@docostler i just find it kinda ironic that at a place where a lot of great physicist have been, and where the desk of Faraday stands nobody got the idea of installing a heat pump to regulate both heat and humidity in that place. heat-pumps are one of the greatest inventions of physicists because not only can they regulate a rooms temperature but also think about the fridges & freezers that increase foods shelf live drastically
Climate change
@@docostler lies lolz
@@pinocleen It was my Canadian attempt at British weather humour. Sorry, eh.
Everyone talks 101 201 stuff. I need 401 501 stuff.
Conventional theory. Relies on faith. Redshift has been disproven.
No ET yet.
Sorry, before watching this, I will finish your recent conversation with Eric Weinstein first... Keating is everywhere! Thanks for your time.
I'm like OUT5Y0 that's crazəə
❤
Ok who at the Royal Institution thought that bringing in a genocide denier was the best idea?
After Keating made a video for PragerU I could no longer take him seriously. Its no secret that organization operates on agendas, not objectivity.
Dr. Brian Keating talked to someone. Oh my! Maybe the audience of PragerU needs to encounter actual scientists as that might create curiosity and lead them to learn something.
So you are a much better human than the Prager U folks....
@@sentientflower7891 politics & science are different...
@@savage22bolt32 any scientist provided an opportunity to teach should do so.
@@sentientflower7891 absolutely agree 👍
always amazes me that someone like Dr Keating could be a good scientist and believe in God at the same time. Baffles the mind how one could and would conjure up excuses for their beliefs.
You're blinded by you're presuppositions : those are conjured up excuses for you believing in U R default position of nonintelligence creating the universe.
What does believing in God have to do with intelligence? Belief in God is a logical conclusion based on all history, experience and scientific thought; but, faith is a choice and intelligent people can make extremely bad decisions.
Your personal beliefs have nothing to do with science. You choose not to believe in God based on ignorance of the world. You cannot claim moral and intellectual superiority when you don't know anything about your history or the foundations of the cosmos.
I'm sensing an overwhelming aura of Dunning Kruger emanating from your presence.
@@Kenneth-ts7bp wtf is this babble, you make a clear case for one of the answers to my question. the fcking insanity
@@Kenneth-ts7bpSo you hold the truth?
@@duartelucas5746 I have a Bible.
another parrot that brings nothing new...yaaawn...😴
. If there is an infinite number of universes, there must be a universe within
which an infinite number of universes does not exist. The fact that your math
allows some phenomena to BE true doesn't mean that phenomena IS true.
You're chasing your own tail when allowing your math to RULE you.
You are speaking nonsense, does an infinite number of bananas imply a baboon? Are you out of your mind
@@ayushsharma8804 Actually, Einstein, it does. But not in this universe. How do you like having a number stuck to the end of your name by Google? Personally, I think it looks silly. But not in this universe. I could keep this up all day, but I only waste a small portion of time blabbing at people whose only contribution to the chatter is:
"You are speaking nonsense, does an infinite number of bananas imply a baboon? Are you out of your mind"
Disappointing. Too much waffle on the basic while too little detail on important stuff like this theoretical scalar field which is supposed to have caused the inflationary phase. Wasted time
Nah, the universe doesn't expand, we are just shrinking so the wavelenghts seem longer to us. Everything else is shrinking as well, all in a synchronus way, exept for lightwaves.
(just kidding, i just like mathematical queivalent expressions)
i like this
😆🤣😆❤it!
Phyicist turned grifter.
Please turn on comments for sue blacks Christmas lecture 2022. I asked for her by name to do my sons autopsy and it was done by a man instead. I'll like to know why my son wasn't good enough for the great sue black? His body was sent to Dundee for her and she couldn't be bothered to show my 6 week old son and me any respect as it soiled him to be touched by a man. She should of done her job but she only does things that bring her fans and fame not actually helping the people of Scotland
This person was allowed to lecture in the Ri???? Wtf😢
Atheists be like "Ummm... actually, Reddit says that the universe was created from a quantum fluctuation that evolved from nothingness."
Atheists also be like "an unmoved mover (God) creating existence is way too far fetched to believe in."
Brian, as you declared ;multiverse', you lost half your listeners. There is only one universe with infinite faces, you were told to believe as 'multiverse' that is not to be observed. The abstract universe with infinite faces is observable.
Typical Brian, he can't help but fail to keep his ego and religion out of his talks. Too sad, makes you happy he missed out on the Nobel.
