SCIENCE MATTERS with Lawrence Krauss (EP08)

[@LocestSwarmSC831]

Lawrence Krauss you're a hero of mine. I've been listening to you since I was a teenager.

[@TheOriginsPodcast]

thanks

[@ceciliapares2804]

He is among my top favorite 🙂👍

[@sparshnigam150]

It's so satisfying listening to actual scientists talk about what's happening, what has happened, what is being discovered, and also about things pertaining to the day-to-day life of an average human being. In today's age when people tend to choose their facts irrespective of the science behind it, we need educators like you to educate atleast the mass who want to be educated. Thank You

[@wellrose17]

Ya know, I wasn't able to afford a higher education . You & several other's as passionate about their work as you have been such an enriching , educational and entertaining part to ( I assume) several people's lives. I humbly and enthusiastically thank you.

[@TheOriginsPodcast]

thanks

[@Syeal7]

I'm sorry education costs money whereever you come from.

[@eris808]

Thank you for your commitment to attempt to educate as many people as possible! It takes a truly brave person to subject themselves to the kinds of talks and debates that Lawrence does. We are lucky to have him!

[@skateebee]

Thanks Lawrence! We need more people like you in the world.

[@TheGreatAlan75]

prof Krauss is my favorite physicist ... I've been watching him for a few years and he is the most fun scientist to listen to.

[@namit7314]

Professor, continue this great work of yours. You are the bridge for people like me who are searching for inspiration to do Science, people who otherwise almost got beaten down by the corrupt system(I have an MS in Chemistry and I am 31 years old). You, Prof Dawkins, Neil de Grass Tyson, Prof. Green and others are doing a great work as Science Communicators. Otherwise, we felt doing advanced Science is something not-reachable. Thank you. Love and Respect from Arunachal Pradesh, India.

[@TheOriginsPodcast]

Thank you

[@kennyhernandez723films4]

Another great podcast . thank you for your intellectual talks. Hands down the most enjoyable part of my day

[@TheOriginsPodcast]

thanks

[@gnschenker]

Wonderful and very informative! Science broken down to the essentials so that interested lay people can understand it. Thanks Lawrence.

[@SilvioBichisecchi]

Thank you Lawrence for another great Science Matters lecture. I just received your "The greatest story ever told... so far" - fantastic reading, you are a great scientist. Thank you!

[@TheOriginsPodcast]

thanks!

[@SourceOfTheRightArm]

So glad to see Lawrence it seems like every time I look him up lately I only find things I've already read or watched

[@TheH8redd]

Can you imagine your life without electricity, without cars, without clean water delivered straight to your house, without a cell phone? We all owe that to science and science alone. Thanks Dr. Krauss, without you scientists, our lives would be miserable indeed. Keep up the good work.

[@MLSK8200]

Yes professor Kraus awesome explanations i love the cosmos

[@woody7652]

What a pleasure, thank you so much, Lawrence.

[@dye013]

Need more science matters episodes! Great work!

[@moon1val]

So glad i've stumbled across your podcasts ! Keep up the great work

[@JorgeFCR2502]

Thank you very much. I watched it twice, it made my evening.

[@nickathans78]

Fantastic, I love this guy! Thanks for the informative video. The speed is awesome, slow talking lecturing bores me.

[@jamessanderson6759]

i enjoy these science matters videos immensely.

[@geoden]

I don't know how old Dr. Krauss is, but given a couple of years, I think I would call him the quintessential physics presenter.

[@Mario-vt2ss]

You are really an inspiration and the best advocate of science. Thank you for unselfishly sharing your knowledge and worldviews. I hope your work will reach as many people as possible. It certainly reached me and I am very thankful for that prof. Krauss. Good luck in future work and win that Nobel prize :-)

[@dresowavy_99]

This is better than my online classes. They are also all about science but damnit this is way more interesting.

[@kingdemon26]

Always an intellectual treat listening to professor Krause👌🏾

[@kashifsyed1846]

Beautifully done professor, looking forward to your next vedio.

[@SaraSara-ti6ex]

WE LOVE YOU LAWRENCE!

[@ceciliapares2804]

Mind blowing professor!! Love it!!!!

[@kmangrave]

Thanks for creating these great episodes, you are a legend

[@gruelichkulsheim9445]

EXCELLENT!!!!!

[@constpegasus]

Thank you Lawrence.

[@conorhope2307]

Thanks for keeping the concepts simple enough for a mere biologist to comprehend ;) Awesome videos, keep it up.

[@rustyspottedcat8885]

Perfect explanation.

[@rushchax]

I cant wait for the new book.

[@luckan20]

Awesome video.

[@korooshkhosravi1261]

[@fadhligaba2990]

Thank you for feeling out the education gap that our school system simply overlook, Professor.

[@CreamyBone]

Much love to Mr.K 😊👍

[@tims.440]

Awesome!

[@nylehaywood2471]

A universe from nothing is a great book now got all your books.

[@TheOriginsPodcast]

thanks

[@robinghosh8891]

I Very Gratefully thank Mr Krauss for his brilliant, knowledgeable discourses..the beauty and Grandeur of the Universe...Mr Krauss is maybe an atheist , but I see a ring on his finger ...only I think that a Christian Tradition would wear one ...being a atheist I wonder ???

[@ColeCoug]

I would love to see a conversation with Victoria Kaspi about FRBs

[@LucAnderssen]

Knowing the answer means nothing. Testing the knowledge means everything. Krauss, Lawrence

[@nemesis9410]

Oh, I didn't know he's back

[@scottfahey3020]

switching to nuclear energy would not only drastically reduce carbon in the atmosphere, but it is the best method of denuclearization (weapons) that has ever existed. also, you rock Dr Krauss!

[@ThomasLBrock]

i really appreciate ya man

[@TheOriginsPodcast]

thanks

[@MelliaBoomBot]

Ive just finished watching Star Trek Discovery Season 2. LK did a book a many years ago called The Physics of Star Trek. Well..seeing his ST stuff behind him I hope he does an update...Ive a superficial knowledge of Physics but sci fi a huge interest. I try and try to understand and try and make analogies in my mind by just letting it wash over me. His enthusiasm and knowledge inspire me greatly..It is a shame we are led by big manipulative Ferengi at the end of the day who put acquisition before vision.

[@babylongate]

Laurence Krauss knows exactly how to avoid talking about moving speed of the galaxies and how fast they travel, because of that he understood General Theory of relativity and keeping a parallel vectors of galaxies and compare them together when calculating them in space and time, and it’s something we can’t do when they are that far away from us, so he avoid the cosmological innocent small lies about telling us how fast galaxies travel in space. Lol that’s so cool to know that you have knowledge, and absolutely, Science matters of course.

[@haimkohan9241]

[@jeffe976]

I wish you could do a 24 hour podcast

[@kimsung2384]

This is a question for Lawrence. What programming languages do you use for studying the universe? Do you do “any” development or do you rely on using pre-developed packages (e.g. vendor packages). Thanks

[@TheOriginsPodcast]

I am behind most of my students.. I used basic for a long time, then fortran.. had to be able to read C once my students used that. Learning python.

[@kimsung2384]

The Origins Podcast Thanks for the reply. Fortran - a fantastic language. I don’t mind C or C++. I can’t stand Python as it’s a dynamically typed language. There are however, some useful mathematical libraries in Python

I wish I could ask Prof Krauss just one question. 1. Would Prof Krauss give every dollar he has, to have the answers to his 3 biggest questions? Would those answers be worth having to start over financially?? 😊 ... And if YES, what would those 3 questions be?????

[@danfredericy]

speaking of the JWT, what's the latest? is there a launch date yet???

Perhaps the "missing mass" really is that there is no mass. Dark Matter could just be overstretch sections of spacetime. What is during the big bang while atoms were forming and the fabric of spacetime was growing faster than the speed of light, that sections of spacetime hit a yield point and left pockets of gravity around everywhere matter was being created. So, maybe it is missing mass because there is no mass to detect. Dark Matter may just be empty pockets of warped geodesics that create gravity wells, but I could be wrong. I think its as good as a hypothesis as any...

[@collybeans586]

How many subscribers matters. No one think you have a million anyway, just because we cant see it. Plus its fun to keep track of.

[@BaconbuttywithCheese]

So, what could be causing the 8% CO2 excess in the atmosphere? If travel, as you say, has been stifled for a number of months with no noticeable decline? I am guessing here that the ppm curve would not react immediately to a decline in fossil fuels, more likely different fuel is being used in different ways i.e. electricity generation versus transportation?

[@BlackEpyon]

There's also positive feedback loops. Ie: melting permafrost releases trapped gasses, which warms the climate and releases more trapped gasses. And so on.

Check the Solidworks forum the questions asked devoid of Academic instruction. The academics left. Yeah, I got a window straight in and I'm watching them build. The Physics will keep your buildings up. Unlike the hospital that collapsed in China. They need it. And we'll help.

[@mikewallace4205]

[@humanrightsadvocate]

Every time he says "dark matter", I hear "something we don't understand".

[@HexxuSz]

which is completely fine

[@deputydog1995]

Indeed.

[@SmigGames]

How else would we begin to study what we don't understand? Not mention it?

[@mrloop1530]

It just shows, you've paid attention. Good on you.

[@bonjstuff3309]

As i understand it the indoor co2 ppm is usually much higher than outdoor. Poorly ventilated buildings IE: offices, schools, workplaces average 1000 ppm but can often reach well over 3000 ppm. At 1200 ppm human cognition will begin to be negatively impacted. This is a real problem even at today's co2 levels. In large cities with old or poor building design the ppm is even higher. If we leave it too long we will be too stupid to solve anything. In short, we are fucked.

Which part of the Big Bang theory predicted the baryons make 5 percent of the universe? You have estimated the baryons' density in the universe by observation, not the Big Bang theory's prediction.

[@jonbainmusicvideos8045]

so conventional theory says that when all the matter in the universe was densely packed near the singularity - then there was not enough pressure to form heavier elements? - makes no sense - especially when the only way to generate microwaves is from metals, - not from light elements -THINK about it

[@aspencrest]

The background is distracting. How about just books next time? (suggestion box)

[@marculmer9790]

What do you think about the hashtag "ShutdownSTEM" and its popularity?

[@BlackEpyon]

The whole thing seems to be built on the non-sequiter that STEM is contributing to racism.

[@Petrov3434]

A big favor if I may: Dear Prof. Krauss -- can you comment on Prof. Penrose’s CCC (Conformal Cyclic Cosmology) hypothesis, his utter disbelief/rejection of "inflation" in trillionths of trillionths second after Big Bang and the contradiction of entropy that his hypothesis addresses/solves. Many thanks in advance. PS: So far I know of only one of your colleagues theoretical physicists who is on record of doubting the "inflation" -- Sean Carroll who gave it only 50% chance of being correct... ;-))

[@TheOriginsPodcast]

I know of no good theoretical or experimental rational for the CCC.. As for inflation, almost all the evidence from modern cosmology is highly suggestive that it occurred.. I give it at least a 95% likelihood.

[@Petrov3434]

@@TheOriginsPodcast Thank you very much -- much appreciated. I know that I am using your precious time... I have most of Penrose's (and all of your !! -- "The Atom" and the wonderful on Feynman are among my favorites) books; currently struggling with his incredible mathematics book "The Road to Reality". In his "Fashion (strings), Faith (observer effect) and Fantasy (inflation)" book he rejects the inflation hypothesis -- in his newest "Cycles of Time" (a new view of the universe) he offers an alternative hypothesis claiming that it resolves entropy contradiction.... Once again -- much gratitude for your work and sadness about religious extremists using all possible methods to attack you. Stay well and young forever !!!

[@BlackEpyon]

@@Petrov3434 The idea of a cyclic universe isn't a new one, but it'd be pretty hard to demonstrate with a universe that appears to be on a runaway course towards heat death. Not that I'm any expert on the subject.

[@franklangelotti585]

Mr Krauss I know nothing about cosmology so be tolerant of my question. If the known universe evolved out of nothing and that nothing occurred at the time of the Big Bang, and since Black Holes, that absorb huge amounts of, light, energy, mass exist, Is it conceivable that our universe is the result of that discharge at the other end of a Black Hole that exists in ANOTHER universe, and so could there be multiple other universes forever unknown to us?

[@lkrauss1]

maybe

[@JungleJargon]

Hey, Lawrence! You know, of course, that the photon is not limited by time or distance. Only things with mass are limited by time and distance. Show us your "brilliance" : ) ...my friend.

The idea of a creator just doesn't make sense to me in any way. The universe has lots of seemingly random weirdness.. like ... What was the creator's reason for having planets traveling at a speed of 10 million miles per hour because it's going around a black hole ?? What purpose does that serve? What if the meaning of that?? It seems like a quirk to me, just some phenomena that came out of a RANDOM and violent accident like a big bang. No reason or purpose

[@kurtlowder3276]

a little bit of good news. new record for the price of solar power fell to 1.35 cents per kwh hour. the record in 2015 was just under 6 cents. energy storage costs are falling even faster. Tesla is worth $180+ billion, while, GM is under $50billion. this signals that energy storage costs are going to continue to plummet. solar, wind, energy storage, and EVs get cheaper every year and its not by a small amount. I think the two biggest things that advocates can do is push for early adoption of Teslas and fake meat. Tesla is going to be so massive and really alter capitalism in my view. that is where the brightest minds are going and their culture really motivates them to work an extraordinary levels. I fully anticate they will transition transportation to carbon neurtal within two decades. self-driving taxis will be 10 cents per passenger mile by 2030ish. for comparison the average cost per passenger mile of a US bus system is 92 cents per mile. yet so many advocates are pushing for buses instead of EVs. people are going to throw away cars when self-driving taxis/shuttles are this cheap. self-driving taxis will allow us to get rid of traffic so despite covid we will see greater urbanization. parking lots will disappear quicker than people realize. Tesla's innovation just cannot be underestimated. their cooling and heating systems are just astonishing and this is going to lead to very efficient HVAC systems that are cheap and reliable. another random tangent. projectvesta.org is looking very promising. we are going to need much less government intervention than we thought. I am not saying all activists should switch. but we need way more activists focused on early adoption of cleantechnology and fake meats. we need more sustainable intentional living communities, where poor people can get together to pool resources and be the early adopters of this tech, which starts out expensive but drops quickly in price. the political system is completely broken. we just have so little chance of success there. However, we can science our way out of this problem. so many billionaires are lining up to fund this stuff. we are just about at a tipping point where fossil fuel companies really start to hurt. we won't be able to beat them in the political arena until we build up the clean tech industry which is booming. I really think we need a paradigm shift. we have to get away from just scaring the fuck out of people. we have to make them see that early adopters are the keystone. like look at tesla, they have not even sold a million cars, but their battery prices are down 90%. in a year or two, we will have a million-mile battery that can go over 200 miles and it will cost below 100 per kWh. again, the cheap evs, allow us to lower energy storage costs, which then allow us to get 100% renewable energy. so it's all about the EVs. yet we have so many advocates wrongly claiming EVs don't help. they are just a stepping stone. we are not going to replace 2 billion gas cars with 2 billion EVs. more like 200 million self-driving taxis, which will be recycled. these taxis will be used for 5-10 years then their batteries can be recycled or reused for energy storage. a rough estimate is another 10-20 million evs sold and then everything else is a domino effect. carbon taxes, green new deals, etc would be great, but its time to be real and really look at our tactics. I am convinced early adoption is the most important thing we can do. fake meat could easily be 1/5 the cost of real meat by 2030ish. so get out there and buy your plant-based burgers. I expect burgers in 10 years to be a combination of lab-grown beef and plant-based substitutes. we only get there because early adopters prove the market and then the research money comes in. sorry for the jumbled response. I never wanted to take on this role. I am just a guy in the comment sections, but now I write for a major cleantech blog. the blogs are so far ahead of the peer-reviewed science. literally, there are so many great news stories that we cannot keep up. I am serious. I am just a disabled middle school science teacher with a business background, but my articles have been tweeted out by people like elon musk and bill mckibbon. scientists are way too conservative when it comes to predicting the cost declines of cleantech. it keeps falling faster than the vast majority of them predict. They keep looking at things linearly. They keep looking at worst-case scenario. its dangerous groupthink. They keep complaining about a lack of government action. but there are other ways. it is only going to take a few more early adopters to reach a serious tipping points in a number of industries. and I have not even mentioned AI yet, which will only further accelerate the rate cleantech innovation. I can't keep up with the positive number of stories, but we don't hear about them from our leaders. they are just stuck on the negative ones, and it's creating a whole generation of nihilists that could be making a massive difference.

you have to have Tony Seba on. he has been right about cleantech when so many scientists were wrong. his new work on fake meat and dairy is groundbreaking rethinkx.com
