Holt Burdette haha! No problem, I think another guy did it though too, but I didn’t notice it till I spelled the whole thing out. Wish I had known! Lol
The mouthful basically means that everything always actually moves in a straight line - gravity doesn't **attract** anything, rather, it is able to warp that straight line into what we call a curve.

9/11 question... Do you know why a feather and a bowling ball dropped in a vacuum from the same height at the same time will reach the ground at the same time? The answer is because while in free fall they both weigh exactly the same, zero weight, and there is no force acting on them. So where did the weight and the force come from to destroy the twin towers when all of that weight was supported for 30 years? The NIST answer --> "Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the *falling* building mass, the building section above came down **essentially in free fall**, as seen in videos"...But free fall means not **falling**, and it also means no weight, and no force. --> ua-cam.com/video/E43-CfukEgs/v-deo.html

Wow that stopping of water flow of dropped bottle is the coolest thing I've seen. Just that one short demonstration opens up a whole vista of understanding!!
Question, is saying "dynamic effects" in this NIST document the same as saying "dynamic weight"? My understanding is that objects falling "essentially in free fall" would have very little weight of any kind with respect to their "static weight", or any falling objects that do not "slow" as they fall, can only have a maximum weight of a "static weight"? Am I right or wrong? NIST WTC Towers FAQ 31...? Quote word for word... "Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the falling building mass, the building section above came down *essentially in free fall*, as seen in videos. As the stories below sequentially failed, the falling mass increased, further increasing the demand on the floors below, which were unable to arrest the moving mass." "In other words, the momentum falling on the supporting structure below, which was designed to support only the static weight of the floors above and not any dynamic effects due to the downward momentum, so greatly exceeded the strength capacity of the structure below that the structure below was unable to stop or even to slow the falling mass. The downward momentum grew larger directly proportional to the increasing falling mass." Now can you envision a falling bottle that falls faster and faster and at the same time the water squirts out harder and harder? This is what the USA government is telling you happened on 9/11.
Puro, I sometime have this similar thought that God could be the evolved and transcended collective human consciousness in future and we are just it experiencing it's past through the flow of what we call time! But the trouble is, as always, what came first! And the cycle goes on!

I just love, when someone is hyped about something. I'm not that much into science myself, but if someone starts to tell me about something science-related and he just seems as happy as this guy, I'm really starting to get interested.
Yea I was like ok I need to look up what all that is and means. I like Colbert brings in science professors and even ask them not to dumb it down but challenge us to understand.
My thought too, and my greatest hope is that he did that recognizing the world of resources at the everyman's disposal today. And what do you know, a few comments up someone's typed it up so you even know how to spell everything right. Now let us go, and learn and make merry!
BTW one thing to note - the explanation using the rubber sheet is misleading and wrong in many ways. It seems to assume relativity is only about space being affected by mass and shows nothing about time. I am not gonna explain all that here but if you wanna know why check out Veritasium's video on relativity.
If anyone hasnt read Dr. Greene's book "The Elegant Universe", i cannot recommend it enough. He is able to explain the most radical nuances of quantum mechanics, string theory, theoretical physics and so on in the most beautiful, simple and thought provoking ways. Him, Michio, and the great Brian Cox are truly the stewards of the highest forms of sciences today.
String Theory still does not function. It is a waste of time. Feinman lectures are better, more entertaining, and do not pretend to more knowledge than we have - but do support quantum theory whose calculations work.
@@artimp152 i’m going to bet that you just heard string theory was bad from a youtuber and are regurgitating their opinion and that you don’t have a degree or any experience with physics
I did read his book The Elegant Universe. I also watched his 11 hour lecture on General and Special Relativity. To his credit he takes complex ideas and make it understandable to a lay person, who is not good in Mathematics, like me.
@@EHS611 I also watched that lecture, I was amazed at how engaged I was throughout the whole thing. The understanding I had coming out was awesome. He's a true educator.
HarindeR SaharaN Some basic understanding is handy but you don’t have to. The book is specially made for the wider audience to understand without any deep mathematical insights.
He always has scientists and retains some knowledge, although a comedian, he still has excellent questions and some understanding which makes it all more entertaining. I love when the host has some actual interest in science and not just trying to poke fun at scientists.
And he didn't belittle Greene either, was clearly interested in his explanations. Most people would put down an intelligent person simply because they don't understand him.
A good teacher is always understood by others. This example made the whole concept clear as a bell for me. I got it!!! Thank you Dr Greene, and Stephen! A very good visual demo for both topics. Excellent!
Gurpreet Singh Matharoo. Lol good one. But sadly reality is that these people are flat earthers and they need this dumbed down farther.... to say a pre-born.
Brian Greene is really, truly amazing. During quarantine, he had a video series on UA-cam called "Your daily equation", which meant that every day he posted a video where he explained some physics equation so that we all could understand. In this way, he would connect us all while we were at home. Every friday, he even had a live stream where we could ask him about anything regarding science. In this way, I was even able to ask him about a few things 😀
But Brian Greene said the water is squirting out the holes because gravity is pulling down on the water. "Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the *falling* building mass, the building section above came down **essentially in free fall**, as seen in videos"...But free fall means not **falling**, and it also means no weight, and no force. --> ua-cam.com/video/E43-CfukEgs/v-deo.html
The falling water bottle was an awesome way to demonstrate the equivalence principle. Brian Greene mentions very quickly that the curvature in time as well as space is important and doesn't go into it more, but he means something like this: the rubber sheet represents spatial curvature and you can slice spacetime so you have many copies of the rubber sheet stacked together. Moving forward through time forces you to move upward through the stack, but the *true* time direction you experience gets pulled slightly inward by gravity, so your overall motion arises as the combination of both space AND time bending toward the sun.
Steven Kapturowski Holy shit, thank you for that comment! It made me think deeper into the problem, and I think I finally got it! So basically, it's like time is just another spacial dimension, in which we are moving with constant velocity(which we preceive as time passing by) at all times, and the curvature, which mass produces, extends into the future(which is basically just a direction if we consider time as a spacial dimension), and the fact that objects with mass get drawn into that curvature is due to that constant movement in time!
It's even stronger than that. The overwhelming majority of the acceleration we experience towards the earth - and everything experiences towards everything else - comes from the curvature in time specifically, not of space. Spatial curvature contributes to more exotic effects like lensing and black hole dynamics.
@@jmcsquared18 exactly I was just going to explain that. For the most part, gravity is just matter bending space so that relative to spacetime curvature, you're actually not moving through space at all but only through time when you and another object of mass accelerate towards one another. If we could think in four dimensions these concepts would be so easy and kindergarten level intuitive, but unfortunately we're stuck in our boring 3D 🙄
I should have known that bottle example would do what it did, but was that ever cool seeing it in action. That was awesome! He is REALLY GOOD at explaining stuff like this :D
Devon Miller there’s another Brian of physics. His name is Brian Cox. He also has a great way of explaining this stuff to people who have difficulty comprehending it.
"So Albert Einstein says that space-time is a 4-dimensional hausdorff differential manifold, on which a metric tensor is imposed that solves the Einstein field equations, and that metric tensor gives rise to geodesics, and objects that are not experiencing any other force will move along the geodesics described by that metric." In case you wanted to look anything up. ;)
@@guptadagger896 The "line with a double point" (two copies of the real number lines identified except at the origin) is a differentiable manifold but not Hausdorff.
FINALLY. I've been saying this for a while, I want smart people not to be cool by explaining this simple but by showing how incredibly difficult it is what they did and FINALLY someone gives the opportunity for people to take a peak in the mind of scientists and see how much work it is. I LOVE IT.
Brian's water bottle example helped me understand the equivalence principle a lot easier. That less than 30-second explanation at the end made my head explode!
The advantage of having a smart host is that a lot of smart people get invited and get asked a lot of smart questions. That demonstration would help many laypeople get an understanding of how exactly gravity works.
@@spacewitchvulcan Technically his sentence was still correct, since nobody _absolutely_ understands general relativity and physics. Honestly though people make mistakes. Not every sentence gets typed out perfectly, sometimes we make errors in spelling and grammar, and sometimes we just have a brain fart and type some stupid shit. So I personally try to avoid correcting anybody on stuff like that. The only time I really "correct" people is when they are spreading lies or misinformation, because that bothers me far more than somebody mixing up "their/there/they're" or something else along those lines.
can anyone tell me the episodes where he interviews or has guests that aren't celebrities(basically people who will waste my time)? This was informative and I'd like to see more.
+kevokoma Pretty much every episode, he does the Daily Show style routine, has a celebrity, and then has a political person, or science person on. it's a mix. He basically turned the late show into The Daily Show.
Hey if you guys want to understand more about how special and general relativity works, how humans' thoughts on the matter have evolved with the work of Einstein and other key scientists, or if you just need more examples to try to really wrap your head around a lot of the concepts, check out the Space, Time and Einstein course at www.worldscienceu.com. Brian Greene does a really good job, and the courses do a great job at making these mind blowing things relatively easy to understand.

Brian Greene is leaving a great legacy of trying to encourage more awareness of science to the public. Great guy
PBS Spacetime. Awesome channel, has a wonderful playlist on general and special relativity. GO NOW!!!
No u
Ur mom space
Excellent job by you Brian! Keep teaching us, we need it!
When my mom walked in I immediately switched to porn cause it was easier to explain.
Underrated comment 😂🤣
@@SRVarma1993 copied comment.. ^^
G-string theory
@@RSBLMC92 wtf XD
Hold Up 😱
I should have known that bottle example would do what it did, but was that ever cool seeing it in action.
That was awesome!
He is REALLY GOOD at explaining stuff like this :D
Brian Greene is the rock star of physics.
Devon Miller nope that's Brian Cox
wow .
Devon Miller there’s another Brian of physics. His name is Brian Cox. He also has a great way of explaining this stuff to people who have difficulty comprehending it.
Yes he is
And so is Brian May.
The passion he speaks with is so contagious 🙂
this was truly an illuminating demonstration!!
"So Albert Einstein says that space-time is a 4-dimensional hausdorff differential manifold, on which a metric tensor is imposed that solves the Einstein field equations, and that metric tensor gives rise to geodesics, and objects that are not experiencing any other force will move along the geodesics described by that metric."
In case you wanted to look anything up. ;)
@@guptadagger896 The "line with a double point" (two copies of the real number lines identified except at the origin) is a differentiable manifold but not Hausdorff.
7:13 “that’s the good stuff right there” 🤤
The last part is pure flexing by professor Greene 💪
This whole segment was awesome
7:12 Woah, that was a badass explanation
FINALLY. I've been saying this for a while, I want smart people not to be cool by explaining this simple but by showing how incredibly difficult it is what they did and FINALLY someone gives the opportunity for people to take a peak in the mind of scientists and see how much work it is. I LOVE IT.
I love Colbert's segments in science on his show. It's always very interesting.
What a wonderful demonstration and vivid explanation by Brain Greene.
The best demonstration I've ever watched on the General relativity theory. Thank you!
"Stand back Issac, Alby's here"- that was so 😆😆😆😂😂😂😂😂😂
Brian's water bottle example helped me understand the equivalence principle a lot easier. That less than 30-second explanation at the end made my head explode!
I love science so much and I'm so glad you're doing this, Stephen! MOOOORE (please)!
Love it when they bring science to talk shows , very useful and intriguing
I very much enjoyed that mic drop at the end.
I'm so glad I clicked on this. That experiment was epic
If only every teacher and professor of science was this exciting and passionate!
The advantage of having a smart host is that a lot of smart people get invited and get asked a lot of smart questions. That demonstration would help many laypeople get an understanding of how exactly gravity works.
I love this segment!!!!
More of this please
Brian, you are a superstar scientist. I really appreciate how you explain and make modern physics concepts seem so easy to follow. Thank you.
7:12
That's a moment cap says to tony stark: speak english.
Yup, except of course that Tony Stark was just making shit up and Greene isn't!
Wasn't he speaking in english already?
Oh i love it, this is remarkable promoting science to the people
I really love Stephen for actually asking Dr Greene to say that at the end. Brilliant stuff.
It was rehearsed
I love Stephen for always giving so much time to science
Professor: **says something no one absolutely understands**
Audience: 👏👏👏👏👏👏👏👏
Story of my life in college
"Absolutely no one" would structure a sentence that way. Are you sure you're in collage?
@@spacewitchvulcan English is not everyone's native language.
@@spacewitchvulcan Technically his sentence was still correct, since nobody _absolutely_ understands general relativity and physics. Honestly though people make mistakes. Not every sentence gets typed out perfectly, sometimes we make errors in spelling and grammar, and sometimes we just have a brain fart and type some stupid shit. So I personally try to avoid correcting anybody on stuff like that. The only time I really "correct" people is when they are spreading lies or misinformation, because that bothers me far more than somebody mixing up "their/there/they're" or something else along those lines.
@@spacewitchvulcan Next time you're correcting somebody, make sure you're not misspelling *college* .
You didn't have to clap, you know?
The last part just blowed my mind.
First time I saw the water bottle expt I was in tears. It's so beautiful. So elegant. And so captivating.
Einstein after reading newton books on gravity be like "hold my beer"
*papers
More like "Halte mein Bier" as he was German XD
*beer slips from hands and falls to ground without spilling until it crashes in to floor*
Einstein: This gives me an idea....
Or "hold my photons"
He didn't drink so....idk
Great guest.
Im so glad when he has guests you wouldn't t expect!
3:31 -stephen be like - yeah man,I am like that...lol😂
your comment deserves my reply ahahhahahhahah
@@Egyptiangamer77 thanks!
can anyone tell me the episodes where he interviews or has guests that aren't celebrities(basically people who will waste my time)?
This was informative and I'd like to see more.
You'd be surprised as to what kind of insights some of the celebrities actually bring to the table. They're not all just eye candy and gossip.
+kevokoma Yeah most celebrities are celebrities for a reason especially actors who have honed their craft to a phenomenal and mind bending level.
+kevokoma You should watch the one with Pewdiepie. It will change your life. His best guest so far.
+kevokoma you dont want your time wasted, dont watch a comedy show you plonker
+kevokoma Pretty much every episode, he does the Daily Show style routine, has a celebrity, and then has a political person, or science person on. it's a mix. He basically turned the late show into The Daily Show.
The world needs more show like this...
love to see the excitement that professor was almost going to stand-up while he's sitting.
Thaaaaaank you for this!!!!
Brian Greene is awesome! I love his documentary on String Theory!
stephens a hell of a host
Please continue to have scientist on the show. Brian Green is a Star amongst nerd circles.
I m seeing this video after four years...since u uploaded!!!
Thank you, Stephen, for promoting intelligent education. 🤓
Hey if you guys want to understand more about how special and general relativity works, how humans' thoughts on the matter have evolved with the work of Einstein and other key scientists, or if you just need more examples to try to really wrap your head around a lot of the concepts, check out the Space, Time and Einstein course at www.worldscienceu.com. Brian Greene does a really good job, and the courses do a great job at making these mind blowing things relatively easy to understand.
Tommyhillpicker how about you go and fuck yourself!
I tried accessing your shitty adress and all i found is some crap for register for the courses and shit like that.
@Den Ax Dude, Well, all you have to do is register for a course. But it's completely free. And the series on special relativity is the best I've ever seen.
Brain is absolutely both intriguing and entertaining.
Thanks,
❤Todd
This is beautiful, how pedagogy has evolved in different ways.
Newton: I leave it to the consideration of the reader.
Einstein: hold my beer...
Einstein: hold my apples
4:03 that single dude that started clapping XD
Very well done Mr Greene
OMG I finally am able to understand this theory!! I never thought it would happen :-)
7:38 "That's the shit right there" saying it while pointing at the science guy!
1:55
Newton : I will leave it to the consideration of the reader.
Einstein : I got this one, stand back Isaac Albie is here 😂😂😂😂
I love these people who explains the theories in a more colorful way.
i like how he is teaching this with such joy
SO. FUCKING. AWESOME
