This was by far my favorite lecture I've seen from the Royal Institution so far! And endless props to Dan Hooper for his explanation of everything. It was simple enough to understand from a layman's point of few, yet detailed enough to give a deep enough sense that one could give a detailed explanation to a person that hadn't watched it and still have said person understand. But even more impressive is that it was explained in a way that gave rise to more questions than answers in a satisfying way as opposed to one that just muddied the water more.

Exceptional talk on this most fascinating subject. I've watched many such TH-cams which include Cosmic Inflation, and there's one thing that I always fail to understand. While Cosmic Inflation offers a solution to many puzzles, I never understand why it solves the puzzle about all points of the universe being observed to be at the same temperature 'because there was never time for them to have been in contact'. I can never square this with the notion that that same observable universe was originally vastly smaller than a proton, implying that everything was very much in contact with everything else. Please be sure that I know it's me that's thinking wrongly about this, and I'm very willing to learn.
I know that there a lots of people smarter than I am. However, I don't think that it is anything other than speculation that the entire universe was smaller than a proton. Perhaps they have created mathematics that say so but "created" is the key word here.
They have supposedly ruled out the singularity as being physically impossible. But the revised size of the possible smallest universe is supposedly about the volume of a human body.🤯
What most people don't know is that it's all fictional. But it keeps math heads in a very lucrative career. Like a lot more things. "All that we KNOW is that we KNOW nothing."
As an engineer I really appreciate what the scientists/physicists (including theoretical)/mathematicians/etc. have done to increase knowledge. It was a hard call going in to the career choice. These fields drew my interest quite a bit, as well. Except maybe math. By the time I got to DE I was feeling more and more lost, or at least a bit too heavily challenged.
This is only one theory, you know. The Steady State theory is just as valid at this point-even more so if you consider that new discoveries show that red-shifted light is attributable to more than just distance, as experiments have now proven, and Arp has documented incessantly, may he rest in peace. My thinking is that if you say that you *think* something is true, then you are open to experiencing new concepts about your observations of your universe; if you say that you *know* something to be true, you know much less than you think, and; if you *believe* something to be true, then you will listen to no one about anything, because in the end, the sad truth about humanity is that our *beliefs* trump our logic, always.
Who is Arp? I have questions myself because we have built an entire image of the universe and the history of it, just on the observation of the red shift. But what if the red shift has another explanation? what experiments? I always keep in mind that it is a human weakness to expect that everything must have a beginning and an end.
Finally, a clear explanation! THANK YOU!!! The same subject is usually covered by endlessly repeating the same old tired statements without clearly stating what they mean.
Fabulous lecture. Thank you. I'm still not follow his explanation about what the universe is expanding into though. But I do appreciate that he had plenty of caveats regarding what they know and what they don't. Sounds like a lot of faith is still required here too. This is how science should be--lots of discovery yet to happen. Really enjoyed it.
@@ecosseman I have, as yet, watched this video. But scanning the comments section, I came across this... "The 'somewhere' can't pre-exist time and space." Hmmmm....isn't that what happened in the beginning? Before time and space existed there had to be some sort of 'somewhere/something'. I'll watch this, and get back at ya later...
This was a great talk on many levels. He gives us a peek at just how fascinating the universe really is, it gives me a sense of mind bending distances and time.
@@yutehube4468 No you didn't mention the bible or say anything with substance. For me to have a straw man argument you would have to be for or against something. you would build an argument on that basis and make rebuttals ect, you didn't. You made a vague lazy statement. I made an assumption.
I still remember reading in New Scientist the first indications that the expansion of space-time was accelerating! His analogy of throwing a rock upwards & it accelerating away from your hand is perfect. That's just what is happening. I'm convinced all these puzzles aren't just loose ends and that to progress it'll take a revolution just like relativity & quantum mechanics. The one fear i have is that maybe we won't be able to work it out. I mean, you could spend years trying to teach your dog orbital mechanics. You'll never get anywhere because the dog just hasn't got the brain to understand it. No matter how hard you try. Who's to say that our brain that evolved on the plains of Africa is able to grasp what is really going on. Maybe we're the dog confronted with orbital mechanics? But, that's no reason to quit. It's amazing how far our primate brain has taken us. I'm 56. I hope we can at least glimpse a path ahead before i'm toast!
@@Aengus42 > At age 73.5 i prefer ASAP. After all, the only nonlethal cure for mass-stupidity is "wising up" (usually due to karma, pain, failures, tragedies, etc.).
He starts off by saying space isn’t expanding but matter is contracting. So does that mean that the universe occupies no more space than when the “expansion” began?🤔
Artur Gasparyan in order to make money in science you have to get into something nobody knows about, nobody wants to know about, nobody cares about, and doesn’t make any difference to life as we know it anyway. They literally throw money at you for stuff like that. Nobel prizes, statues House a Lauds all the birds you can use. Holiday villa and your own TV channel. Who’d be a scientist
Impressive, to say the least. I had no idea how anyone could possibly ‘know’ what happened in that hypothetical tiny fraction of a tiny fraction of a tiny moment in time (when time had not even begun). In some vague way this does seem plausible-or maybe it doesn’t
@@patkennedy2620 Sagan was a persuasive science popularizer, but there is a good bit of imaginative speculation in some of his presentations. Good science requires hard evidence. If that is missing, as it is bound to be when talking about beginnings, endings, time, space, zeroes, infinities, eternities, the cosmos, etc., the explanations and hypotheses hazarded by some enthusiastic worthies, plausible though they might seem, must be kept in the tentative ‘maybe’ category until proved or disproved
Sadly, one of, if not the, main problems when it comes to public support for science is that most people are just so ignorant of the recent mind blowing discoveries that have been made, especially regarding our place in our infinitely complex and downright crazy ass universe. It's painful how clueless most folks are. I find myself in a constant quest for new knowledge and information about cutting edge discoveries and I couldn't just stop learning and yearning to know more. I think it really all boils down to the fact that we currently have a large number of hardheaded, close minded, dumbasses infesting our population right now. Until that inevitably gets better, things will continue on their current path.
Uh, duh, but what if it turns out the universe is not crazy, just misperceived, misinterpreted, and misunderstood? After all, "QM cosmology" wonks "study" much less that 4% of 4% of cosmic reality (mainly in their heads, after blowing up tiny fractions of the 'field').
I've had my own theory about this for maybe 2 decades now. I'll try to explain it clearly and quickly. I think there was once a single massive blackhole that held all the matter in the universe confined to a single point. One spark and boom!!! Everything explodes outward, gasses and elements thrown to the cosmos. The universe is expanding, eventually, they say, it will contract. I think it will contract back to a single blackhole and start all over again. For all we know, this has happened 3 or 4 times already and this is the first time all the right pieces came together in just the right place to create life.
My thinking too. To think that the space itself is expanding along with the materials in it is to limit yourself and automatically say that we don't what was there before bigbang. Unless space is not space but is a material in itself. Also we would never know whether there was life or not in the previous instances.
Easy to understand?? The test is tomorrow morning at 0800. I want to sit next to you so keep one hand in your lap so I can cheat at bit.....or cheat a lot.
Extremely persuasive about 1904. In 1929 Hubble realized dark energy. And Einstein's spacetime... And his accurate model of an atom is all incredible. And now we are all cosmologists.
An excellent talk. Very enjoyable. Thanks again RI for putting on these fascinating lectures. (P.S. I usually try to explain the expansion of space itself with the analogy of blowing up a balloon to be larger and larger with dots on it representing galaxies, etc. It's probably not a very accurate analogy but it does help to get the nature of expansion across. Well, at least my dog thinks so.)
@@Dr10Jeeps My self dont think that our universe is expanding, what it is is that all matter acomodates into space in 7 different levels so all they are looking at are the wave length of such levels. About God well I steped aside long time ago.
@@Dr10Jeeps Our Sun expands and contracts so all stars do, as well galaxies, cluster of galaxies, super clusters of galaxies and so on so as well our universe cause as we know till now the cosmos is made of stars to where ever we see, this gives a reason to say that as well our universe does that but wait stars are made of atoms and all atoms some how are ENTANGLED by pairs WHY then should not stars be entangled too? How can larger things scape from been entangled if all things whatever they are must to be made of atoms? My self believe that not a thing may scape from some how been entangled as well universes.
1 In the beginning God created the heaven and the earth. 2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. 3 And God said, Let there be light: and there was light.
Enjoyed the talk basically he is talking about what God created, God is the Creator/Father of all things. Time does not effect God because it has no relation to God which means eternity means nothing to God because God has always existed and created the universe. When God created the universe time was also created.
Still amazes me they can figure out the events within the first billionths of seconds after the bb yet we still cannot create a material that fills potholes that last longer than 3 months. We have the most complex machines scanning areas billions of light years away, rovers on Mars borings holes.. Yet a simple paper hole cutter for a voting machine can't seem to pull it off leading to bus loads of seniors coming in and reading each punch by hand.

14 Billion Years is a REALLY REALLY REALLLY REALLY long time when you think about it. Leaves a universe open to so much possibilities. It must be a really interesting universe and beyond. If only I was indestructible, I'd fly all throughout IT's wonders
@God_Laughs _At_Atheists I agree. I believe in GOD, but I don’t believe creation stopped after earth. Also, before Earth he had already created, remember 'The Angels' ? That is a race. And clearly ONLY God will reveal what's out there, hence why we haven't found or seen anything with life yet. We are limited until GOD decides to open those new scrolls and revelations He talks about in the holy scriptures.
DARK ENERGY is the stuff that was here before the universe... and will be there after. It's the fabric our universe is sewn into. It's the Exoverse. What? Noel Prize? Nah, I'm cool.
It's an easy premise to come up with. I studied geology. It's kind of like tectonic plates only on a Universal scale. It just makes you wonder how tenuous our perceived universe is. Consider that we live on the skin of our planet. Now we might be living on the skin of our universe. Hmmmm. Time for more coffee.
So here we are less than two years later, and the James Webb Scientific Telescope is now in L2 orbit, having unfolded flawlessly, and burning less fuel than expected to the point that it has enough fuel to keep it operating for at least 20 years, instead of the 10 years that was expected. Within six months, the mysteries of the universe will begin unfolding.
Yet, those of us stuck in The Box of obsolete QM faux-cosmology will want all the cosmic realities to keep "fitting" into The Box -- as the number of unexpectedly surprising "anomalies" and excuses multiply exponentially.
He is a master educator! Best teacher of the explination of the birth of the universe, i've heard so far! Brian Cox, Brian Green move over! We have another kid on the block!!
Question: If gravity affects time, and the universe was smaller, wouldn't time have run different back then? so how long was 3 seconds from the start? (my question relies on external reference and there is none).
Not an expert, whatsoever, but I believe that the Higgs Field defines the speed of light, therefore, if the Higgs Field was different then, it would follow that light would travel differently in that field, and time would have to be treated differently. Then again, I could be completely wrong. That is why I love science; finding out you are wrong means that you actually leaned something. Great question, by the way.
I've been contemplating what I feel must be a paradox, but I've yet to see an astronomer address how strange it is explicitly. If when we look at a galaxy that's billions of years old and billions of light years away, and we are seeing it as it was billions of years ago, then where is it right now? And if it is actually closer to us now than it was then, it feels kind of strange that we wouldn't see it from its closer vantage point, even though the light we see now is older than the light of its closer position. So the actual galaxy itself, any of them, could truly be at any number of positions, we simply can't see it because the light hasn't reached us yet. Also makes me wonder if we will ever witness the unsettling phenomenon of a galaxy or cluster of stars appearing from nowhere.
I agree with your paradox, maybe scientists need to better define how they conceive their interpretations of telescopic images of the cosmos?.. If space were expanding then we should witness such an effect within the space we dwell in, surely? Or are we missing something??... But I have to disagree with Bill (below) Light waves and Sound waves for that matter do not dissipate, scientists have recently calculated the light from a telescopic image of two colliding stars to be a billion years old, and more recently another scientific installation claims to have heard the sound of these two stars colliding??...
@@mysticnomad3577 Light waves do not dissipate, scientists have estimated the light from many of their telescopic images of the cosmos to be millions, even billions of light years away...
There is no beginning, there is no end. Our puny minds will never understand that concept. Our limited brains cut off trying to understand eternity. Yea. Verily.
@@strange-universe Where can you take something that supposedly happened billions of years ago as facts? It's all speculation, and in this case, massive.
When science is shown to have been wrong it is ALWAYS corrected by other scientists - IE science. When religious dogma is shown to be wrong it just denies it and keeps on repeating it regardless.
We only realize that the visible universe is bigger and more extensive and has more to it than is possible for any human to comprehend. We will always know virtually nothing about it because it is so remote from us and contains more information than is possible to know from our absolute solitary existance on Earth.
Opening statement: we understand most of what we SEE in the sky (correct) we don't understand over 90% of what's out there! Sounded a bit like the complacency at the end of the 1800's when scientists reckoned they had everything sorted. Looking forward to this
My uneducated self has become reconciled with the idea we'll never have 'everything sorted'; there'll always be something to discover or uncover. In some popular physics book they talked about a game where one person thought of something and described it with one attribute, each succeeding person thought of something which incorporated the parameters of the previous persons and added an attribute. I wouldn't be surprised if we're doing that with nature.
@@jonathonjubb6626 he was contrasting what we SEE (regular matter and light) -- with what we just detect/infer but cannot see (the 2 dark thingies, which amounts to 95% of everything if i'm not mistaken)
Unlikely. The earliest stage of the universe is a thermal state as demonstrated by the CMB and the universe is going towards another thermal state. It looks more like that our heat death is the heat birth of a new stage of the universe.
Great talk. I learnt loads. Did anybody spot the hydrogen fusion reaction at 19:15? I have always thought it started with the fusion of two protons (Hydrogen one or protium ions) like this ¹H⁺ + ¹H⁺ -> ²H⁺ + e⁺ + νₑ. Then fusion of hydrogen one and hydrogen two (deuterium) to form Helium 3. ¹H⁺ + ²H⁺ -> ³He²⁺ + γ. Then the last reaction is the fusion of two Helium three ions to form Helium 4 like this ³He²⁺ + ³He²⁺ -> ⁴He²⁺ + 2 x ¹H⁺. Maybe I am wrong or maybe both are correct? Anyone know more details on the topic?
It seems like the more we know, the more wrong we were about what we thought we used to know. Makes me think that once we learn even more details none of this will be accurate or relevant.
I am a layman physicist! 🙂. So I can ask Qs that may not be scientifically correct. My Q is this. At 40:45 to 41:45 you talked about two points at opposite ends of space that have always been so far apart that they couldn't have shared information, given the limit on speed of light. Could it have been due to entangled particles, from the very fraction of the moment of B Bang, having been pushed to extreme points by Inflation carried some intrinsic info instantaneously revealed at the two extreme points? I am only asking, because right after the BB, entanglement might have been more of a rule than an exception.
Outstanding presentation for the layman...have much appreciation for understanding our universe, its complexity, the parameters man is discovering daily, dangers facing space exploration and effects on astronauts reaching out further in our location in the universe...great lecture!
Ok, does anyone else think he has an uncanny likeness to George Clooney??? By the way, that was a fantastic lecture and had me glued to the screen to the end, loved the Q&A afterwards as well.
When Edwin Hubble measured the red shift of other galaxies and concluded the universe expansion, he probably didn’t count Andromeda? Because as we know Andromeda is actually traveling at us.

@To Release is To Resolve Either space is expanding or it isn't... When it seems like it's expanding it's because of the same principle as is going on inside your body (because space also is inside you). The principle is called 'growth' :)
@@mymysticalside2842 There are other forces at play. Same way static electricity makes a balloon hold to a wall and stop falling. As @To Release is To Resolve already said, read about strong nuclear force.
@@gabrield.6406 I'v been through all that stuff. You are saying the meter (in space) is getting longer while (on the planets) it remains the same. Relativity! If space is growing and we remain the same size then it's also true that we a shrinking. Is it the strong or weak force that makes us shrink? The Universe is growing for the same reason you and I are growing...
Time runs slower when gravity is higher. So during the first second of the universe time is really slow. This is something I have a hard time getting my head wrapped around.
If the atomic clocks on the satellites that run our GPS didn't correct for the 28ms/day difference with those on Earth, it would no longer be accurate within 15 minutes...

While Cosmic Inflation offers a solution to many puzzles, I never understand why it solves the puzzle about all points of the universe being observed to be at the same temperature 'because there was never time for them to have been in contact'. I can never square this with the notion that that same observable universe was originally vastly smaller than a proton, implying that everything was very much in contact with everything else. Please be sure that I know it's me that's thinking wrongly about this, and I'm very willing to learn.
I know that there a lots of people smarter than I am. However, I don't think that it is anything other than speculation that the entire universe was smaller than a proton. Perhaps they have created mathematics that say so but "created" is the key word here.
They have supposedly ruled out the singularity as being physically impossible. But the revised size of the possible smallest universe is supposedly about the volume of a human body.🤯
Ah! Really kills the idea of the magic man in the sky doing it with a 'Big Abracadabra'.

As an engineer I really appreciate what the scientists/physicists (including theoretical)/mathematicians/etc. have done to increase knowledge. It was a hard call going in to the career choice. These fields drew my interest quite a bit, as well. Except maybe math. By the time I got to DE I was feeling more and more lost, or at least a bit too heavily challenged.

This is one of the best lectures on this topic on YT

Best public lecture I've heard in years. You cover everything, with very latest understanding. Thank you, Sir.
This is only one theory, you know. The Steady State theory is just as valid at this point-even more so if you consider that new discoveries show that red-shifted light is attributable to more than just distance, as experiments have now proven, and Arp has documented incessantly, may he rest in peace.
My thinking is that if you say that you *think* something is true, then you are open to experiencing new concepts about your observations of your universe; if you say that you *know* something to be true, you know much less than you think, and; if you *believe* something to be true, then you will listen to no one about anything, because in the end, the sad truth about humanity is that our *beliefs* trump our logic, always.
Who is Arp? I have questions myself because we have built an entire image of the universe and the history of it, just on the observation of the red shift. But what if the red shift has another explanation? what experiments? I always keep in mind that it is a human weakness to expect that everything must have a beginning and an end.
Those were some of the clearest explanations I have ever listen to. Nice to have access to this great content
If you want sensible and much clearer explanations you need to learn about the Electric Universe theory.
Or the truth, "Ken Wheeler" or "Lori Gardi". Plato's Field Theory before atomists came up with Science Fiction.
Most of them come up with about the same since I began seen this kind of programs.
@@sanctusexitium9956 I agree that this stuff makes no sense, but the electric universe has many crazies in it.

Finally, a clear explanation! THANK YOU!!! The same subject is usually covered by endlessly repeating the same old tired statements without clearly stating what they mean.
Fabulous lecture. Thank you. I'm still not follow his explanation about what the universe is expanding into though. But I do appreciate that he had plenty of caveats regarding what they know and what they don't. Sounds like a lot of faith is still required here too. This is how science should be--lots of discovery yet to happen. Really enjoyed it.
@@ecosseman I have, as yet, watched this video. But scanning the comments section, I came across this... "The 'somewhere' can't pre-exist time and space."

I still remember reading in New Scientist the first indications that the expansion of space-time was accelerating! His analogy of throwing a rock upwards & it accelerating away from your hand is perfect. That's just what is happening.
I'm convinced all these puzzles aren't just loose ends and that to progress it'll take a revolution just like relativity & quantum mechanics.
The one fear i have is that maybe we won't be able to work it out.
I mean, you could spend years trying to teach your dog orbital mechanics. You'll never get anywhere because the dog just hasn't got the brain to understand it. No matter how hard you try.

Great lecture! One of the rare ones where i watched from beginning till end. :)
He starts off by saying space isn’t expanding but matter is contracting. So does that mean that the universe occupies no more space than when the “expansion” began?🤔
Excellent presentation!
Dan Hooper. This is my first exposure to him but hopefully not my last. The man is an incredibly gifted speaker.
Wow this is a really great lecture. How did I miss it 4 months ago? ❤️
We where all wondering that
Question? Does Hubble deep field look like an explosion? Or maybe an even spacing more or less? Also its dimension that is expanding not space.
So Mr. Hopper, you were there at the beginning of the universe. Fascinating.
0:23 No, they are not wrong about people not supporting or having an interest in science. They were obviously talking about the US.
If people really care about and support science, how come RI can only gather 890$ per month on Patreon?

They literally throw money at you for stuff like that. Nobel prizes, statues House a Lauds all the birds you can use. Holiday villa and your own TV channel. Who’d be a scientist
Impressive, to say the least. I had no idea how anyone could possibly ‘know’ what happened in that hypothetical tiny fraction of a tiny fraction of a tiny moment in time (when time had not even begun). In some vague way this does seem plausible-or maybe it doesn’t
Look up Carl Sagan on TH-cam- older but really excellent talks
Nobody can know, and it is sheer arrogance to pretend to know.
@@NondescriptMammal My reaction also
@@patkennedy2620 Sagan was a persuasive science popularizer, but there is a good bit of imaginative speculation in some of his presentations. Good science requires hard evidence. If that is missing, as it is bound to be when talking about beginnings, endings, time, space, zeroes, infinities, eternities, the cosmos, etc., the explanations and hypotheses hazarded by some enthusiastic worthies, plausible though they might seem, must be kept in the tentative ‘maybe’ category until proved or disproved
Sadly, one of, if not the, main problems when it comes to public support for science is that most people are just so ignorant of the recent mind blowing discoveries that have been made, especially regarding our place in our infinitely complex and downright crazy ass universe. It's painful how clueless most folks are. I find myself in a constant quest for new knowledge and information about cutting edge discoveries and I couldn't just stop learning and yearning to know more. I think it really all boils down to the fact that we currently have a large number of hardheaded, close minded, dumbasses infesting our population right now. Until that inevitably gets better, things will continue on their current path.
some people are just dumb like this guy above me. oops
@Fred Jammerson no, I generally think I don't know much of anything because I'm only human.
Uh, duh, but what if it turns out the universe is not crazy, just misperceived, misinterpreted, and misunderstood? After all, "QM cosmology" wonks "study" much less that 4% of 4% of cosmic reality (mainly in their heads, after blowing up tiny fractions of the 'field').
That’s a pretty arrogant prejudge-mental statement in itself.
I've had my own theory about this for maybe 2 decades now. I'll try to explain it clearly and quickly.
I think there was once a single massive blackhole that held all the matter in the universe confined to a single point. One spark and boom!!! Everything explodes outward, gasses and elements thrown to the cosmos. The universe is expanding, eventually, they say, it will contract. I think it will contract back to a single blackhole and start all over again. For all we know, this has happened 3 or 4 times already and this is the first time all the right pieces came together in just the right place to create life.
My thinking too. To think that the space itself is expanding along with the materials in it is to limit yourself and automatically say that we don't what was there before bigbang. Unless space is not space but is a material in itself.
Also we would never know whether there was life or not in the previous instances.
And where did the “one” black hole come from?
What I learned is that the inflation isn't the worst thing that can ever happen.
Dan's lecture was very vivid and easy to understand. I was captivated the whole way thru. Thank you for this upload :)

Extremely persuasive about 1904. In 1929 Hubble realized dark energy. And Einstein's spacetime... And his accurate model of an atom is all incredible. And now we are all cosmologists.

An excellent talk. Very enjoyable. Thanks again RI for putting on these fascinating lectures. (P.S. I usually try to explain the expansion of space itself with the analogy of blowing up a balloon to be larger and larger with dots on it representing galaxies, etc. It's probably not a very accurate analogy but it does help to get the nature of expansion across. Well, at least my dog thinks so.)

@@Dr10Jeeps My self dont think that our universe is expanding, what it is is that all matter acomodates into space in 7 different levels so all they are looking at are the wave length of such levels. About God well I steped aside long time ago.
@@Dr10Jeeps Our Sun expands and contracts so all stars do, as well galaxies, cluster of galaxies, super clusters of galaxies and so on so as well our universe cause as we know till now the cosmos is made of stars to where ever we see, this gives a reason to say that as well our universe does that but wait stars are made of atoms and all atoms some how are ENTANGLED by pairs WHY then should not stars be entangled too? How can larger things scape from been entangled if all things whatever they are must to be made of atoms? My self believe that not a thing may scape from some how been entangled as well universes.
1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
3 And God said, Let there be light: and there was light.
Enjoyed the talk basically he is talking about what God created, God is the Creator/Father of all things. Time does not effect God because it has no relation to God which means eternity means nothing to God because God has always existed and created the universe. When God created the universe time was also created.

@God_Laughs _At_Atheists I agree. I believe in GOD, but I don’t believe creation stopped after earth. Also, before Earth he had already created, remember 'The Angels' ? That is a race. And clearly ONLY God will reveal what's out there, hence why we haven't found or seen anything with life yet. We are limited until GOD decides to open those new scrolls and revelations He talks about in the holy scriptures.

Aw shucks.
This talk was excellent. It helped me more fully understand a number of concepts I’ve always had a problem understanding.
So here we are less than two years later, and the James Webb Scientific Telescope is now in L2 orbit, having unfolded flawlessly, and burning less fuel than expected to the point that it has enough fuel to keep it operating for at least 20 years, instead of the 10 years that was expected. Within six months, the mysteries of the universe will begin unfolding.
_"the mysteries of the universe will begin unfolding"_
Well, a few more of them, at least.
Yet, those of us stuck in The Box of obsolete QM faux-cosmology will want all the cosmic realities to keep "fitting" into The Box -- as the number of unexpectedly surprising "anomalies" and excuses multiply exponentially.
What makes these people think that time also started with the beginning of our known universe?
He is a master educator! Best teacher of the explination of the birth of the universe, i've heard so far! Brian Cox, Brian Green move over! We have another kid on the block!!
Question: If gravity affects time, and the universe was smaller, wouldn't time have run different back then? so how long was 3 seconds from the start? (my question relies on external reference and there is none).
What a fantastic question that is. I'd never considered this before, but now I need to know the answer to it!!!
Not an expert, whatsoever, but I believe that the Higgs Field defines the speed of light, therefore, if the Higgs Field was different then, it would follow that light would travel differently in that field, and time would have to be treated differently. Then again, I could be completely wrong. That is why I love science; finding out you are wrong means that you actually leaned something. Great question, by the way.
I've been contemplating what I feel must be a paradox, but I've yet to see an astronomer address how strange it is explicitly. If when we look at a galaxy that's billions of years old and billions of light years away, and we are seeing it as it was billions of years ago, then where is it right now? And if it is actually closer to us now than it was then, it feels kind of strange that we wouldn't see it from its closer vantage point, even though the light we see now is older than the light of its closer position. So the actual galaxy itself, any of them, could truly be at any number of positions, we simply can't see it because the light hasn't reached us yet.
Also makes me wonder if we will ever witness the unsettling phenomenon of a galaxy or cluster of stars appearing from nowhere.
You're worrying or contemplating things that have no bases in fact.
Making claims that can't be proven are a waste of time and energy.
Light waves disapate.
They do not travel forever so little Johnny can see them on earth.
I agree with your paradox, maybe scientists need to better define how they conceive their interpretations of telescopic images of the cosmos?.. If space were expanding then we should witness such an effect within the space we dwell in, surely? Or are we missing something??... But I have to disagree with Bill (below) Light waves and Sound waves for that matter do not dissipate, scientists have recently calculated the light from a telescopic image of two colliding stars to be a billion years old, and more recently another scientific installation claims to have heard the sound of these two stars colliding??...
@@mysticnomad3577 Light waves do not dissipate, scientists have estimated the light from many of their telescopic images of the cosmos to be millions, even billions of light years away...
@@tiemiahu9947 yeah right, how can it be millions or billions of light years away when everything was created by God about 7,000 years ago

When science is shown to have been wrong it is ALWAYS corrected by other scientists - IE science.
When religious dogma is shown to be wrong it just denies it and keeps on repeating it regardless.
We only realize that the visible universe is bigger and more extensive and has more to it than is possible for any human to comprehend. We will always know virtually nothing about it because it is so remote from us and contains more information than is possible to know from our absolute solitary existance on Earth.
Great lecture. I really enjoyed it very much.
Dont You Mean Great Brainwashing
Opening statement: we understand most of what we SEE in the sky (correct) we don't understand over 90% of what's out there!
Sounded a bit like the complacency at the end of the 1800's when scientists reckoned they had everything sorted.
Looking forward to this
My uneducated self has become reconciled with the idea we'll never have 'everything sorted'; there'll always be something to discover or uncover. In some popular physics book they talked about a game where one person thought of something and described it with one attribute, each succeeding person thought of something which incorporated the parameters of the previous persons and added an attribute. I wouldn't be surprised if we're doing that with nature.

I would like to hear about, how long it was to arrive to the beginning of the time, and what not happened and why before the time.
We are still in the explosion stage of the universe. Someday it will crest (stop expanding) and then begin to shrink again.
Unlikely. The earliest stage of the universe is a thermal state as demonstrated by the CMB and the universe is going towards another thermal state. It looks more like that our heat death is the heat birth of a new stage of the universe.

Brilliant presentation 👏
Great talk. I learnt loads. Did anybody spot the hydrogen fusion reaction at 19:15? I have always thought it started with the fusion of two protons (Hydrogen one or protium ions) like this ¹H⁺ + ¹H⁺ -> ²H⁺ + e⁺ + νₑ. Then fusion of hydrogen one and hydrogen two (deuterium) to form Helium 3. ¹H⁺ + ²H⁺ -> ³He²⁺ + γ. Then the last reaction is the fusion of two Helium three ions to form Helium 4 like this ³He²⁺ + ³He²⁺ -> ⁴He²⁺ + 2 x ¹H⁺. Maybe I am wrong or maybe both are correct? Anyone know more details on the topic?
It seems like the more we know, the more wrong we were about what we thought we used to know. Makes me think that once we learn even more details none of this will be accurate or relevant.
I am a layman physicist! 🙂. So I can ask Qs that may not be scientifically correct.
My Q is this. At 40:45 to 41:45 you talked about two points at opposite ends of space that have always been so far apart that they couldn't have shared information, given the limit on speed of light. Could it have been due to entangled particles, from the very fraction of the moment of B Bang, having been pushed to extreme points by Inflation carried some intrinsic info instantaneously revealed at the two extreme points?
I am only asking, because right after the BB, entanglement might have been more of a rule than an exception.
What an incredibly fascinating lecture!
Outstanding presentation for the layman...have much appreciation for understanding our universe, its complexity, the parameters man is discovering daily, dangers facing space exploration and effects on astronauts reaching out further in our location in the universe...great lecture!
Ok, does anyone else think he has an uncanny likeness to George Clooney???
By the way, that was a fantastic lecture and had me glued to the screen to the end, loved the Q&A afterwards as well.
This talk proves one thing they don't know anything all they can do is make conjecture and assume because they want to reject the truth.
When Edwin Hubble measured the red shift of other galaxies and concluded the universe expansion, he probably didn’t count Andromeda? Because as we know Andromeda is actually traveling at us.
