That first slide... fucking hell. Horrible memories. I'm a 5 year old kid, dinosaur freak. It's history class, subject dinosaurs. I could have had a 10/10 on all questions - if I would have answered truthfully about what I know, but my parents told me to write down biblical answers, and I got a 4/10. I don't think I've ever felt more ashamed than that moment.

Its funny how that's an issue for some people now. "Academic freedom" or some such bullshit. I don't mind people holding their own beliefs but when they take a test in a class they aren't getting tested on what they believe to be true, they're getting tested on what they were taught in the class. Its a shame you were put in that position.

MO change UR last name , the DOG was a child rapist .

the most important thing is: never stop asking questions!

I watched the whole video and stood up and clapped. My siblings thought I was crazy...

Just brilliant! Presented in such a straight forward way I found it accessible but still complex enough to scare away trolls. Perfect balance.

Great educator. Fantastic delivery on difficult subjects.

I never even took a high school class in physics but this man manages to make it all clear and exciting. I am so thankful to have the opportunity to be part of the audience.

Wit beyond measure is a man's greatest treasure. Thank you Mr. Krauss for unraveling the greatest mysteries of our world. A truly wonderful and awe inspiring presentation. We need more people like you.

Hi!.....Lawrence Krauss....Thanks a million for the lecture...Cheers to you

i am 53 years old, I was raised southern baptist. No dancing, no drinking, no fun of any kind. I was baptist by bus. I was a rowdy child and I guess my mother needed a break. There was a church bus that stopped in front of our home on Sunday mornings. The gave me gum and drove me to first baptist church in Paris Texas. I was supposed to go to Sunday school and then children's church, but after a couple of Sundays I heard the story of Moses and the story of him sacrificing his son..... I was 7, but i know i didn't want to know about a God like this, I was truly afraid...... so I hid in the stairwell until time to get on the bus and go home....After a few months I learned to miss the bus..... at 27 I married, started having children at 34.... and started attending church again for the KIDS..... as i listened and learned nothing seemed right..... by this time I have lived in 7 different countries and 2 different states ..... it all seemed like myth, but for my wife and children I went.... was asked into church leadership, budget committee..... i listened to supposedly GOD FEARING people lie, argue, and fight over money..... and I remembered George Carlin act about GOD...... a magical man who lived in the clouds, who gave us rules to live by, and punished us with hell, but he loved us.... but he needed money..... it seemed he was not a very good money manager....... I never had believed.... so there was no loss of faith for me...... so I just gave up and became an Atheist...... but my family and friends didn't know this.... I was a closet Atheist..... I felt alone...... I now live on an island in the western Caribbean. about 6 months ago i discovered Seth Andrews, Aron RA, Richard Dawkins, Bill Nye, and and many others on KZread...... I have realized I am not alone..... the one thing I enjoyed and was missing was the fellowship I got in church...... I have now seen there are many of us, and you guys also have meetings, a social like, supporting each other learning, ect..... I am still alone. My life does not suck.... I own a beach bar and restaurant and resort..... meet 100's of people a week.... most from the Bible Belt..... each night I listen to many POD Casts..... I am now feeling good about being an Atheist..... and have been thinking about coming to some of the events. Hope to see some like minded people soon....... Many cruise ships come to our island .... regular cruises, classic rock cruses, Star-trek cruses..... I was thinking we need to have an Atheist, free thinking cruse. Just a thought..... sorry for the rambling.... its just I have never went public with these thoughts.

Thank you for sharing Craig. Fundie Christianity ruined my life. I actually read the whole book every word of which the Bible bashing preacher waved his fist in the air and screamed at the top of his voice was the word of the living God. BTW, it was Abraham not Moses that was bidden to sacrifice his son. You really are a lucky fucker. A natural born and raised hypocrite. You'll do just fine in and out of religion. Look up some of these scriptures if you ever think you or any of those around you are or ever were even vaguely Christian (it should make you feel better): Mat 6:25 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment? Mat 6:31 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed? Mat 6:34 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof. Mat 6:19 Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: Mat 6:20 But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: 1Co 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ. 1Co 3:12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 1Co 3:13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. 1Co 3:14 If any man's work abide which he hath built thereupon, he shall receive a reward. 1Co 3:15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire Mat 19:21 Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me [and be a possession-less vagabond roaming the countryside, eating from farmer's fields and knocking on doors asking to be given food and shelter]. 1Co 7:1 Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman. Luk 14:26 If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. You are alone? You have a wife and children. You, an owner of riches in a sunny location. Cry me a river and send it to me, here in rainy Kent, UK :-)

The difference betwen science and religion: When faced with the new and unknown, science says: "Hmm, I don't know, let's study it, experiment and find out the truth". religion says: "Hmm, I don't know, let's make shit up". As a result, science is pretty consistent, while different religions make completely different shit up. Yeah, the first option is hard work and not everyone is willing to do that.

Oh, they make shit up and they're not shy about trying to promote it as "truth". :)

+lnpilot +Razhender Wild agreed but you both forget one addintional argument of religious people : unknown is scary and people want definite answers let's see how we can sue that fear to better control the people. And that's in my opinion religious is the most harmful. The parents who indoctrinate their children do it because they believe they're doing the right thing it comes from love and caring most of the time but the religious institutions do it for power.

I absolutely LOVE Krauss' lectures!!!

Thank you for the compliment! Trust me I hung on for years and left the faith kicking and screaming. Reason overpowered my yearning to believe and feel "chosen" and then of course, I had to face my family who are all Christians. Fortunately, after some time they have been as understanding as I could have hoped. There are some young earth creationists maybe on the fence that will be convinced but you are right, the hardcore ones can't let go of their imaginary invisible friend.

I watched this last night and actually cried. I had to come back to it again this evening. Cried again. I have watched many of his presentations, but this one is almost as if it is a Lawrence from another Universe. Makes me think String Theory may be plausible (grin, wink, wink). I feel as if I have been given a precious gift, if only for an instant, I felt as if I shared in the understanding of a true genius. Thank You to all who made this possible is too weak. All I can say is XO XO XO : )

My god, how I miss this man's lectures

Absolutely awesome! I loved the entire video. Thanks

One of the best Krauss lectures I've seen. Good stuff.

That is the 1st lecture I've had the pleasure to see of his. Great job on this one!

Thank you Seth for producing those videos and for bringing them to us!

This is the best physics talk, ever. Lawrence Krauss is awesome. I though I hated physics in college, but it wasn't physics I hated, it was the "no context, just memorize, recite and solve hundreds of pointless identical problems" way they teach it in school.

Really enjoy hearing his talks. He has taught me so much because he makes difficult concepts understandable.

This was absolutely awesome :X

It moves me to tears how this great mind narrates. This is indeed "the most amazing story ever told"! Thank you! (both)

Thanks for this Seth, a real treat!

I live 80 miles away and missed this! I really hope there is another next year!

Another great presentation by Boss Krauss --- brilliant as always ;-)

Wow watching this guys lectures/speeches and he absolutely amazing.

Thanks so much for the quality video upload and all the other work you put into this movement.Lawrence owned it as always :-p

Fantastic presentation from Lawrence Krauss, as per usual.

This was truly amazing! :) Thank you!

Awesome lecture!

This was a really good lecture. Thank you for posting it!

A fascinating lecture.

[sigh] WHERE were guys like Krauss when I was struggling with physics in engineering school 45 years ago? THIS is the kind of approach we need to engage new students in science, engineering and technology in the 21st century!

thanks Seth,, Glad your background is in radio, the sound is good on all your stuff

Thank you Seth for this video. I have always wanted to attend Lawrence Krauss' lecture and now I kind of have. Too bad I could not come to the convention since I live on the other side of the world, but these videos are great compensation. I still have Michio Kaku and Richard Dawkings on my 'lecture list'.

He is such a brilliant man, he could just be studying and furthering the science but instead he knows that educating the masses for free will eventually benefit us all in funding to the sciences that need it.

That presentation was completely AWESOME.

havnt even watched this yet and i already love it

Love this guy i am an absolute beginner in everything about science but have a passion & desire to try a lern more Lawrence realy inspires me to keep trying to understand & explains in a way i sort of grasp. love science

Bookmarked... Awesome video. It vaguely stitch things that I understand together. Need to know more.

Thank you, Seth. I'm ashamed to admit that I had great difficulty in finding a good explanation about why the speed of light is constant regardless of the observer before today and now I have a basis to look into it more thanks to you and Krauss.

Well that concludes today's lecture. And will one of the ladies in this room please give Mr. Krauss the much needed attention we all know he needs? Thank you - thank both of you.

50 years from now the rest will know how brilliant this guy is.

Great lecture from a great mind and a special thanks to you Seth for posting this. Btw, I didn't comment on your lecture but great job with it aswell.

Wow! Fantastic as always Professor Krauss! :)

Amazing!

I feel like my head exploded and I loved every minute of it.

Honestly, that's the exact reason I like prof. Krauss. He can speak very well to laymen like me.

awesome video

That was a fun 90 minutes! I love Lawrence!

I am so glad we have people like you, writing youtube comments and putting these self crowned scientist frauds straight. The inputs of great minds like yourself can't be valued enough. Well done Giovanni. Well done.

Some decent quality footage from a not so prepared auditorium, thanks Seth.

YES FIRST TIME EVER RECEIVING A POSITIVE RESPONE

Brilliant.

Mind......BLOWN!

Thank you Seth. Good job :)

Such a brilliant mind!

"The universe doesn't give a damn about what you think about it, it doesn't give a damn about what you like." I want that on a shirt.

Great last line: "Just not liking an idea is not good enough. You have to test it."

This is how physics should be taught in classrooms not by saying "So X behaves like this and Y behaves like that. And these experiments prove it. That's that.". Mind blowing talk, brilliantly explained.

I want this talk turning in to a book.

by the way great lecture.

Wow that was the first time I understood why the speed of light is capped to 300km/s. And I watched lots of videos on this topic. Thank you Mr. Kraus.

Krauss is one of the most brilliant minds of our time, he shouldn't waste his precious time debating religion.

Mind = Blown

Lawrence has a great sense of humor. I loved the "Lane Craig Syllogism" line.

Thank you for posting these! I was going to get a ticket to this, but spending money when you're a broke college student physically hurts. D:

Mr. Krauss keeps getting aside from his point. Don't get me wrong, its an awesome thing for him. It shows how much he truly love what he's talking about.

Better than a TED talk!

Thanks Lawrence you just explained Special Relativity to me.

I don't understand this...but watching this gives me a sense of undeserved air of intellectual superiority over those who haven't seen it....

I'm in complete agreement with everything you just said. The point of my comment was to respond to a guy who said, and I quote: "philosophy has accomplished absolutely nothing other than to justify incredibly bloody ideologies and cults. Philosophy should be in the trash bin of history right alongside cults and shamans." I'm merely trying to show to him that philosophy is, as you so well put it, an integral part of science and not a separate entity that is somehow useless.

You are one of the rare gems that is actually "brave" enough to seek honest truth rather than just stubbornly clinging to the Buybull. I respect that. To be clear, I was specifically meaning young Earth creationists that subscribe to the BS that the universe is only a few thousand years old, that dinosaurs and human coexisted, etc.

well said sir i totally agree

LOL Saganite! I'm going to use it to describe myself from now on!

This is the second time I'm watching this.

thrilling lecture.even better than his '09 one

I love how he explains things in terms a layman can understand.

Aaaaaarggghh !! Your avatar!!! I've just spent the last few moments trying to flick that bug off my screen.... lol. :)

My head hearts.

in the situations where you would expect the speed of light to be higher or lower, its always time that gives in and bends. These are the situations where you either have one observer moving relative to another or when a gravitational field is involved. in the first case, time passes slower for you if you are moving faster. in the second case, time moves slower when you are in a stronger gravitational field.

You think you are insulting him, but actually you are showing his respect for knowledge. He readily admits there are things we have yet to understand, but we are working on it.

Mind = blown

Hot damn I love this guy! Best science lecturer since ever. Well, Feynman. Which is not to belittle Sagan, DeGrasse Tyson, et al - they are/were general science teachers, and fantastic ones at that. Despite their individual specialities, however, it's explaining general concepts to those with no background in science. Sagan especially - he could cover ancient Grecian philosophers, simple geometry, deep sea life, and potential extraterrestrial biochemistry in the same show.

Krauss is awesome!

It might seem 'unbelievable' but it was actually me who sent Lawrence that child's creationist report from school that he showed. I was amazed to see it on his lecture lol

This is the most funny I've ever seen Mr. Krauss, Nice to see him relaxed and having fun instead of trying not to donkey punch William Lane Craig for two hours. Great talk.

Beautiful video. The only thing which could have improved it would be to replace the audience question with a voice-over so that they would actually be audible or have someone repeat them for Krauss' microphone.

What you're talking about with the fish is called REFRACTION, passing through the water slows light down (light travels through air faster than in water) and 'bends' it making the fish appear somewhere else. It's actually still in the same place. When light travels through a vacuum (space) it's constant and always moves at 186,282mps. When you look at something in space a billion years old, you are looking at the past, because it has taken the light a billion years to get here

Good show I approve

Thats why most people should add to their self proclaimed titles, comedy forms master dominator. Identity...

Well do not feel too hurt about it. It takes people like Krauss to create these ideas and test these hypothesis that make my brain hurt, but I would never know about it if not for people like yourself that have the talent to present it in a manor that I can access and digest.

nice... :) Glad I looked down here... it's amusing how many responses there are, just like the one you submitted which are meant to be serious responses to videos just like this on...

"(if speed is constant than time varies, if time is constant it is speed that changes with reference to a moving object)" Thats it, thats the main thing that is so hard to get your head around. As it turns out, for example when experimenting with ultraprecise clocks, its always time that will go at different speeds, and that fixes everything. For example, for particles in the LHC, moving at 99.9999% of the speed of light, time is slowed almost to a complete standstill.

I love that he's out there doing his thing, I didn't know that. I still wish he had a more effective/measured approach when one on one with religious types. Easier said that done I'm sure.

Dear god, the audio!

Thats the best explanation of relativity Ive heard.

Epic ending: "... the universe doesn't give a damn what you think about. And a damn what you like." -Krauss
