Special  

Glad to see you back! Your book "A Universe From Nothing" is what made me finally give up on any belief in a god and become an atheist, which has changed my life for the better.

“If you wish to make an apple pie from scratch, you must first invent the universe” -Carl Sagan

I'm from Iraq, and I love watching you🙂.

The biggest and best 5 min cooking show in the universe and the proof is in the pudding. Science is the coolest, way before it's time, and I predict this channel will be bigger than Bieber when people finally catch up. Thank you so much its a real pleasure.

"So forget about Jesus, the Stars were kind enough to die for you to exist!" :D

Watching your videos are a thrilling experience. I’ve downloaded them and watch them periodically. Every time I learn more about fundamentals of physics. This particular video is a jewel, thank you Dr Lawrence Krauss 💐

such a brilliant teacher! thank you Prof. Krauss.

WONDERFUL

Lovely.

I love these so much, THANK YOU Professor Kraus.

"We are stardust Billion year old carbon We are golden Caught in the devil's bargain And we've got to get ourselves Back to the garden" -Joni Mitchell

I'm enjoying these short, concentrated, clear discussions of the fundamentals of physics a lot. Thanks! Your distillations of physics remind me of Prof Paul Nurse's discussions of genetics and life.

my fav physicist

Excellent, Dr. Krauss, thank you. I love your picture you carry with you to show people that the Big Bang really happened. I'm sure that goes a long way with creationists. I'd love to watch their reaction to being shown that: "Oh yeah, I see it there, it's crystal clear on your graph, you're right, the Big Bang did happen!" lol

This almost moved me to tears! What a beautifully elegant way of showing this phenomenon. I'm so in awe of the measurements made to calculate these predictions, it's hard to follow without pausing and going back over things! It all genuinely makes sense after a couple of views of each segment! Thanks Lawrence! I'm still waiting for a reading list for my redshift education though!

Mr Krauss THANK YOU for continuing this series. This special episode was fantastic!

Thank the big bang for rice pudding 👍. Oh and sausages 👍

I've read your book "A Universe from Nothing" quite a number of times. So I knew about the wallet thing, which put a smile on my face when you mentioned it. Thanks for taking some time to enlighten us.

Always a delight to listen to Dr. Krauss!

"We are made of star stuff" is one of the great lines from Cosmos.

Insightful as always. Glad you're doing some specials despite the main series being over.

Love your videos, Dr. Krauss!

Great video! This is what I was hoping for after the last video - predictions verified by observation. I really enjoyed that.

damn, just found this channel, i guess i know what i will be watching this weekend :) Thank you for all you do

Thank you, gracias, for the engaging data, now transcending frontiers. Greetings from South America.

Fascinating stuff. Thanks.

"We are stardust Billion year old carbon We are golden Caught in the devil's bargain And we've got to get ourselves back to the garden." Every time someone says "we are stardust" I start singing this Joni Mitchell song! Science. still rules, no matter what the "supreme leader" says!! Thanks again for another wonderful lecture! After almost three months in my condo, I finally took a drive today! Your lectures have really helped me out during this long terrible time in our worlds history! Stay Safe and peace out!!

Follow you for more recipes?? LOL... That was great Dr. Krauss.. You've been hitting it out of the park with these..

Could you do an episode on Penrose's Cyclic Conformal Cosmology theory? That our bing bang was the end of the past eon and the far future of our universe is the big bang of the next eon.

Mr. Krauss, thank you very much for these mini-lectures. Could you please elaborate on Sir Roger Penroses' CCC? Thank you very much again.

Legend

Really highly educational videos Professor Krauss! I wonder if you can explain inban upcoming video multiverse's all 4 levels.

Thank you sir please keep it up.... These videos are inspiring and full of knowledge....please make a video on how we got the lifetime of these particals...is there any equation for that or these results are experimental

Dang! Love it when you go whatever percentage of "full tilt" that was. Still doesn't answer the pressing question: do you take the chicken skin off before or after you cook it?

I'm watching the big bang analyze and talk to itself.

damm that too interesting... thanks

👍🏼👍🏼👍🏼

13.7 billion years explained in 5 mins (ok....give or take 12 mins) ;-). Astounding!. Thanks again Lawrence (sorry, should I say Professor Krauss? I don't mean to be disrespectful!). If anybody still believes otherwise after that unequivocal, indisputable, empirical observations based on those predictions and beautifully described in 5 mins, then as far I'm concerned, it would be waste of oxygen even trying!

If you want to create a video about Physics that lasts quite close to 5 minutes, with a six orders of magnitute in accuracy over its final duration, you have to create Lawrence Krauss first. Thanks for posting them and making them accessible to us.

5 physicist minutes = 17 actual minutes...time IS relative

HE'S BACK

I fuckin love you so much bro

Amazing what can be done with maths. I was okay with maths in school but the schooling system failed to make it amazing.

Another wonderful 5 minutes that felt somehow like 17:37 minutes … but nice ones

@lawrencekrauss when we talk about the universe being a second old, super hot and dense. (Not sure how to ask this) would the density of the universe at that state in time have influence over how time "passed"? So would a second in a universe that dense be a lot longer relative to a second in our universe and would it have any influence over any interactions between particles in that universe. Or maybe I don't make sense haha. Thanks, and great series man!

Thanks very informative and clear. You explained that dark matter is not made of ordinary matter. Do we have any indication of when dark matter was created? Before or after the end of the inflationary period?

The line from Carl Sagan is "if you wish to make an apple pie from scratch, you must first invent the universe"

What a title!

🌌do you think sometimes about why is "space" so cold? We have a impirical data about big bang, but that doesn't mean that universe began from this big bang, but exists these particles etc. due to this big bang.

How can we send questions to Mr Krauss? I have a few I would like answers to.

Students will go to professors, and professors will be the students.

Your beard is getting pretty epic in quarantine professor! Plus an awesome lecture as always. Can you post or say where you got that graph in your wallet please?

if I'm made of stardust,,, then how are there still stars around,,? Now I wait...🤗

Relatively speaking a mild to warm fart could be considered intense heat compared to absolute zero or colder Universe, right? (Like Voyager Probes wall of Fire beyond helios-shield, got no prediction about that intense temperature since equations can still retain values after algebra reconfiguration) I hope Einstein is not disappointed who limited the universe as a machine, whereas differently I think it in combination sometimes even more like a plant organism. I think I have a good guess about at least 4 GROWTH fluctuations which have not decreased but only increases, matter, energy, and exceptionally gravity combinations by area expansions multiplied/added. I like making good guesses before experts confirm with published repetitive emphasis, sometimes limited publication, and sometimes NOWAYS duplicating a journal extremely unknown to me whrefore I am reinventing wheels unknown. Caring less about reputation, regardless I like to think I first thought something out, and so I like to inquire for my wonders. Have yall of academia heard anyone else announce , "Solar Systems spread out thereby interstellar winds against helios-shield, and matter grown benefited also thereby MULTI-FACETED gravities", because I am guessing that is where your arithmetic can be re-interpreted into my different message. Oh hey, what do you think about that?

Where can i get this graph?

I know of no thinking person who unironically denies the big bang

I have the same card in my wallet !!!

Everything everyone knows is a sub set of what Mr Krauss knows lol in terms of Science

I'm sorry, starting with the universe comes after you preheat the oven. Every chef knows this.

Can we dumb this down for non physics people please 😔

Yeah, but if the Big Bang really happened, why are there still monkeys?

So many astrophysicists felt in love with this theory of BBN that they ignored its drawbacks. This theory completely ignores the existence of antimatter and failed to predict the ratio of deuterium by far. Which leads to a complete absurd conclusion that the most abundant substance in the universe can not be found here on earth or our solar system.

I’d disagree with a number of the expressed calculations, thus a number of conclusions... ( never mind me...i actually have difficulty counting to 10, let alone approach such endeavors and contemplations)

God is the explanation for everything.
