As always a wonderful science matters Lawrence delivered in such a way that your varied audience can benefit from it. Looking forward to seeing what JWST will be sending our way all the more after watching this presentation. Thank you for taking the time to develop these programs for all of us.
Small correction: The gold on the mirror has the equivalent weight of a golf ball, Lawrence said its as much gold as if you had a golf ball of solid gold, which would be about 750g of gold instead of the 48g of a golf ball... A golf ball has a volume of 38.8cm^3, 48g of gold only have a volume of 2.5cm^3 3:55
@@TheOriginsPodcast Yeah I know, its a trivial thing you probably just mispoke at 3:55, its a nice and informative video, thank you very much and have a happy new year =)
So excited about the JWST! I know next to nothing about modern physics and astronomy but I can't wait to see what is found out and also to see the new pictures of our universe!
Super excited to watch this amazing machine work over the next decade. We are going to look back almost to the very moment of Creation. How incredible is that
I don't need incredible. Lets look at the word credible. Its derived from credit. Money. It took our money. It also makes it impossible to get our gold back where we need it on earth. Laurence is just posing for the cameras. We need that gold to stop the sun over heating the earth.
Ive totally given up on TV..there may be some utter rubbish on YT but my goodness, there is some really quality, intelligent, entertaining stuff. Well done..:)
God !!! I love your passion for physics Mr. Krauss and I recently finished 'A universe from nothing' , loved it. Congratulations on 100k and yes you deserve more ! Keep doing your good work and hope more of our younger generation people are inspired by you, especially in this era of anti-science skepticism . (Don't mind me using the word 'God' there, being an atheist myself 😅)
Secondary mirror deployed! I think your last microphone sounded better than the one in this episode, but maybe the venue changed. Great informative episode!
Awesome informative video! This is a perfect primer for the future Webb telescope discoveries. Webb is really going to take us back. Very exciting and thanks!
thank you Lawrence. I needed this explanation about JWST. galaxies collapse and make black holes. that matter in the black hole produces a Big Bang and forms another universe thus the multiverse. and then it happens ad infinitum. lumps on all scales form, so true.
3:50 A golf ball weighs approx 48 grams. 48 grams of gold would have a sphere radius of about 8.4mm. A sphere of gold the size of a golf ball would be in the ballpark of 1 kg.
I am from India. Thank you so much for making this complex matter easy for us to follow. This is an amazing talk. I follow uour lectures with great interest and am always filled with admiration at your brilliance. Hope andvpray you get a noble prize as you deserve it
Thank you for sharing your knowledge and understanding of this project and how it may change the way we see the universe around us. Happy new year, and all the best to your family Lawrence. Peace
Lawrence is the best! love this I find Dark Matter in particular quite interesting and its role in the early expansion of the universe. it can't shine by its own light, like hot coals, or even reflect light, like clouds or water. Neither electricity nor magnetism affect it. What a curious thing truly what a great time to be alive.
Congrats on 100k! I love your podcasts… keep ‘em coming. One small correction: you mention the JWST was launched by a rocket “just as the Hubble was (2:13)”. Actually the Hubble was launched from the Space Shuttle and not subjected to the same sort of folding constraints to fit in a nose cone. “April 24, 1990 - Hubble launched. Space shuttle Discovery (on mission STS-31) launched from the Kennedy Space Center in Florida, carrying five astronauts and the Hubble Space Telescope”
Thanks for including numbers, Lawrence. Until now I had always been aware of red shift, but never considered how far it went. I was not expecting factors like twenty. I should have, of course because I was fully aware of Hubble's constant. I just failed to put two and two together. But this raises an important question for me. We know that the intervening space itself has absorption bands due to various molecules, dust etc. But do these operate on the original high frequencies of the galaxies, or the much lower frequencies that we see? In other words, are the inter-galactic absorptions red shifted too, and by how much?
there is not much intergalactic absorption, except by hydrogen, and we measure this lyman alpha absorption to catalogue the ionization history of the universe.
@@dreyn7780 Of course we invented numbers. they proved really useful for counting. If you can find some numbers on Mars, or the Moon maybe, I will agree with you. But as far as I can tell they are an intellectual artefact created by us.
I already can't wait to hear what all new we answer with this gem peering into space for us! Thanks to all who made the James Webb, and got it up and out there! You rock like Schroedingers cat when the box is closed and she knows no one can see her! (
Would the James Webb telescope be able to find any evidence for or against primordial black holes? Are these what you were referring to when you mentioned the chicken/egg quasar problem?
Question : What is the origin of "lumps"? or Why was the early universe not perfectly smooth. - or - If the universe was not perfectly smooth why was it not "symmetrically balanced"? by Symmetrically balanced I mean if "lumps" did pull on each other, why was this pulling not perfectly "equalized" resulting in no net change.
I have heard that for shared instruments like Hubble and say a mountain top telescopes, researchers have to pitch to a team about why they should get to use it for a few hours/days/weeks. If the proposal is accepted and executed, how long does that team get exclusive access to the data they collected? I assume they get exclusive access for a window of time to write papers on what was found and not be scooped by other researchers. But after say 20-30 years, is all the data released to the public? I hope the JWST works. I heard the sun shield deployed ok.
What are the thoughts on fast formation and rapid and repetitive supernova of early stars due to either internal instability or stellar collisions which quickly built up heavier elements early on?
Looking at planets that may support life is not a precursor to traveling since by the time anything got there the planet would have changed to the point it would not be able to support life, much as ours will change. Right?
On tenterhooks as each “milestone” is passed./accomplished. Because everything MUST work the first time. As for goLd. . . Meh. Lots of that in asteroids. . . which is why Elon doesn’t want to go there. An explanation of the various Lagrange Points deserves an episode of its own.. . “Just Saying”
@@karagi101 i was thinking maybe first black holes were the antimatter ones, but yes it is nonsensical since both anti and regular matter were created at the same time suposedly , so the mistery where is anti still stands , LOL , no nobel for me
@@mirko1989 Something happened very soon after the Big Bang to result in an imbalance that favoured matter vs antimatter. This telescope can’t look back to that early time. Many theories exist but it remains a mystery. Don’t give up. The Nobel Prize is still up for grabs.

@@TheOriginsPodcast you don’t say ;). I meant a normal golf ball weighs about 50g, so one made out of gold would be considerably more. I’ve never held that much gold (in volume), but it must be more than half a kilo surely? Again, sorry if I misunderstood the gold segment. I did rewind to double check I hadn’t misheard, maybe I’ll try again. Enjoyed the video. Very much hoping the telescope deploys as planned, and really excited about what we may discover with it.
@@markparker5585 You're right. They are only comparable in weight, not in size. Solid gold has a density of 19.30 g/cm^3 (according to Wikipedia) and a golf ball is about 40 cm^3. So a golf ball made of gold would weigh almost 800g.
@@JungleJargon no, it has always been practice with space telescopes to focus on certain range of spectrum, say X ray telescope requires different hardware than infrared telescope, etc., you build a telescope that instead of doing everything poorly does something narrow but very well.
