Another truly fascinating talk by Lawrence Krauss. I'll have to watch it many more times to wrap my head around some of the things that were said, but that's the beauty of learning.

Science is moving forward so fast. Every time I see a great lecture like this it blows my mind on how people are able to develop this knowledge. It makes me proud again to be part of this human race, but it is actually no wonder that so many people are stuck so far behind. But I'm so glad that Lawrence is capable of preparing and cooking a scientific meal in a way that I can not only digest it, but actually really enjoy eating it. He is my master chef of science.

This should be required viewing for everyone!

"...The galaxy contains a lot of dust." Yea, no kidding. Most of it is in my living room. All joking aside, this was a great talk, as usual.

Awesome. Awesome cubed. Our grasp has truly exceeded our reach.

Very intriguing Dr. Krauss, thank you for your extraordinary insights to the ever expanding field of Cosmology. I yearn to have the opportunity to learn from you at Arizona State University one day. My deepest respect for what you do and have accomplished in your life. Hopefully, as a species, we can continue to push the frontiers of human knowledge and gain true understanding of the origins of matter and energy in our Universe and beyond.

At 15:00, prophetic! The waves have indeed been picked up last week ...

Wow... you so good Mr Krauss !!

Back when these events were real events with good content and speakers, and an audience. The best of times, yeah.

I REALLY ENJOY LAWRENCE AND ALTHOUGH I AGREE WITH HIS POLITICS I THINK HE SHOULD LEAVE HIS LITTLE POLITICAL COMMENTS OUT OF HIS PRESENTATIONS. IT IS BENEATH HIM.

Excellent lecture.

26:21 mark: The bicep experiment published results that showed gravitational waves at a fraction of a moment during the big bang? What does this say about gravity itself? It was here before time or what? What does having gravity it such an early instant mean? That gravity was always here AND did create the big crunch?

I wonder if there might be some kind of interaction/ correlation of random frost pattern direction, to an already identified subparticle and its movement. just a random thought I had around 35 minutes into this.

I only live an hour or so away from where this happened. I should have gone :-( ...Oh look! He's using an Audio-Technica belt-pack!

Mr. Krauss, thanks for confirming what most of us know about that grinning jack-as$$ in charge of tx is all about off camera.

Smart guy

Every moment is a new beginning +1=0 now -1 then was just the end of another moment of time.. . .

The people on video r smart. the people writing comments r not

44:20 , I remember when that semi super conductor building was cancelled... They were gonna build it down the street from my apt. Considering how my life has gone since...I wish they would've built it and created a black hole right next to my house, if you know what I mean.. ?

this man should be an "alien" . love u dr lawrence .

Wonderful advocate for science 5 multiverses out of 5!!!!

Krauss: "and then inflation ended" Guth: "no so fast there, Larry"

I hope he gets over this whole saga with these women

To know in 2022 Rick Perry was our Energy Secretary and “ controlled” Nuclear energy and weapons, to hear someone say HES MORE STUPID IN PERSON is HYSTERICAL “ NOW!”

Ask three questions from yourself after waking from a dream. 1. The observer of my dream was conscious or unconscious? 2. The observer of my dream was in my dream or in the universe? 3. Is the observer of my dream still conscious? If so then where? Answers of these questions will enable us to understand the beginning of time.

Love Krauss's evaluation of Rick Perry. Nice guy, stupid, but nice.

We look back 10 billion years to stars -and probably intelligent communities -which no longer exist - from a place which, at that time, did not exist.

My second favourite scientist after Walter from Fringe.

Time is an expanded fabrication that expanded along with space that expanded. You can't have expanding space without expanding time.

(Everything = Zero plus Not Zero ) .......what made it not be Zero ? does anyone know? try to explain it someone. HOW can you get Nothing from Everything and Everything from Nothing? How? does anyone know ? thanks

why do people never give the date of the recording?

Just 711 views? Sigh......

I wonder if the legs on the snake are same location as their vestigials legs if any left now

Krauss is the best at making the complex understandable. Hopefully more will listen and give up their God delusions.

Lawrence Krauss is one of my heroes, but his joke regarding Neil DeGrasse Tyson fell flat! Great vid though, more please.

Ask Krauss about Frank DiMeglio.

8 of the 19 9/11 hijackers dislike this, i wonder why?

where was everything before it just exploded into this World ? does anyone know? Time = Zero plus Not Zero

Turning physics into M.Physics!

7:39 "..primordial lumps" 🤣

My mother in law has a blackhole wich has no gravity at all.

SOUTH CAROLINA WANTS TO KNOW WOULDNT LIGO DETECT THOR AND THE HULK FIGHTING???

i am taking a guess. Maybe all the things we see out there in the World are maybe just all derived from "thought" so to speak the way Issac Newton said. God's thoughts ......Newton wanted to know them i think he said someplace. Because "Thought" drifts above everything else and yet, everything in the whole World is involved in Thought one way or another. i dont know i quit -- this is fun though anyway

So... Steven Spielberg is a physicist now? Cool.

Not sure this has been posted on here before, but fuck it: www.scientificamerican.com/article/gravity-waves-cmb-b-mode-polarization/

Really good lecture. Facial hair looks kinda funny on the shape of his face ;p

aah aah uum... and um ... aaah *laugh AAAH AAAH AAAH UUUMM

I know Lawrence Krauss didn't post this video but if protons only have a life span of 10 to the 33 years and currently protons are on the order of 10 to the 10th years old. Then the experiment expecting to see a proton decay in container that holds 10 to the 33rd protons shouldn't yield results. Please any physicists reading this comment correct me if I'm wrong but wouldn't that experiment be akin to putting babies in a room and expecting to see one of them die of old age.

1400 years ago universe expanding is already written in holy Quran...Quran 51:47........SAHIH INTERNATIONAL And the heaven We constructed with strength, and indeed, We are [its] EXPANDER.

Dear Larry: Thought experiment: PhD Theses have been written Defeating the Born Gay Hypothesis. Perhaps You Hypothesize Exactly Why, and Who was responsible for that. The kids will really Enjoy Hearing it from You!!! 💡😁🧐🤓✅💥💥💥🎉🎉🎉🎉🎉 It’s like pulling teeth.... Hahahaha

Regarding God, how can you prove God one way or the other:? no one knows either way. (i like to think there is a God since no one really knows. amen.)

If Professor Krause understood time he would encounter real physics. Apparently he likes Science Fiction.

Thank god for gravity or my truck wouldn't stay on the road

You can't use expanded time as a valid measure of historical time because it was no time except when it expanded.

I love this so much *tells awkward joke* crowd laughing *and ehm, and ehm, ehm, but, ehm..*

hahaha! Neil Degrease Tyson! LOL!

There is no time before the creation of time and there is no absolute measure of time or distance in the universe so there is no way to determine the age of the universe.

In the beginning God created the heavens and the earth and yet paradoxically/as a contradiction Genesis then immediately says that the earth was void and without shape and darkness was over the surface of the deep. The fact is that Genesis was talking of a flooded, totally submerged world, originally inhabited by Satan and his evil/fallen angels, which God had destroyed by water. Remember Jesus said he saw Satan fall down to earth like lightning. Please note that the earth and the water were not created within the six days of creation. Here are what were created from the first day to the sixth day: light, firmament, vegetation, sun, moon, stars, living creatures and man. Genesis 1:9 And God said " Let the water under the sky be gathered in one place and let dry ground appear." Nobody knows exactly how long the solid ground and the water had originally existed before God made the earth a habitable place again but this time for mankind. Unlike Noah's flood that original flood was totally devastating leaving nothing in its path.

PROOF OF EXISTENCE OF ALMIGHTY ALLAH The Almighty Allah Challanges the Mankind in Holy Qur'an : Blessed is He in Whose hand is Dominion and He over all things Hath Power - He Who created Death and Life, He Who created seven heavens one above another; Thou canst see no fault (want of proportion) in Rahman's creation So turn thy vision again Seest thou any flaw ? Then look again and again, thy sight will return unto thee weakend and made dim. ( Again turn thy vision a second time ; thy vision will come back to the dull and disconfited, in state of wom.)". (Qur'an,67:3,4) Explanations:- The seven heavens are arranged in layers one above another. This verse indicates to the multiverse. There are seven skies only, not infinite numbers of universe. In mathematical or scientific terms,any claim which is not supported by experiments can not be an acceptable proposition. Existence of Almighty Allah is proved by ' intelligent design , based on the infinite complexity of the myriad life forms which surround us and of which we ourselves are part. Intelligent design argue that to say that such complexity couldn't arise out of random chance. It is impossible. Almighty Allah -- the Originator of the heavens and the earth! " بديع السموات والأرض " ( ,2:117 ,Qur'an) challenged the Mankind if they have power to penetrate (all) regions of the heavens and the earth, then penetrate(them). The universe is so vast and stretches beyond our ken , that our eyes aided with the most powerful telescopes will confess themselves defeated in trying to penetrate to the ultimate mystries . The universe is expanding faster than light speed. The universe is much larger that we can see it or go beyond. It is becoming bigger and bigger. Can NASA, ESA and all other space research agencies of the world all altogether accept this challenge of Almighty Allah? If not, they have no justification to deny the existence of Almighty Allah relying on theirs very little knowledge of the universe. In the above mentioned Qur'anic verse, We are asked to observe , study and research the universe carefully and deeply. and as minutely as our powers will allow with the aid of scientific machines and most advanced telescopes. We shall find no defect in Allah's handicraft. It is over our own powers that we shall fìnd fail to go beyond a certain compass. DR.MOHAMMAD LAEEQUE NADVI Ph.D. (Arabic Lit.) Director Amena Institute of Islamic Studies & Analysis A Global & Universal Research Institute, Kolkata nadvilaeeque@gmail.com

Hugh Ross talks about alot of the same things but from a God perspective.

Definition of science: "the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment". Yet Krauss continues to claim how the big bang came about as though its fact. It can only be theory. Was he there? A strong theory perhaps but not fact. His attitude and approach to teaching is tiresome. Enough for me now ...and I usually find him interesting.

TDS

I wish Lawrence would not keep pushing his political views onto his audience

lets the sarcastic BS begin!

There is no way to measure the age of the universe because there is no standard of the passing of time.

bs

you will get nothing with this kind of knowledge.

A left wing presentation into the origins of our universe so of course 5 minutes in he's ripping on Republicans. You can't make this stuff up.

S Arabia could be boycotted. Stop driving.

57 minutes to clarify what you know in the first seconds ; God isn't helping enough so we need to discredit him!!...??... Krauss is such a bitter loser!! God gives him infinite freedom and this is the repay he gets!!...
