beginning? and the answer is: you know, it just happened, but there is laughter. I'm very happy with that too, but it actually makes it easier. For me it may not be true but how can there be another good thing that if the universe occupies all the space listen I know it is expanding to nothing no no it is not expanding to nothing it is not no if it inflates a balloon yes and I put points on it on it, yes, and sure if I put an extra dimension on it it will expand into the room, but if I only consider the two-dimensional surface of the balloon, it will just get bigger, it won't expand to anything, okay, yeah, and if you Do you imagine our universe is like the two-dimensional surface of the Moon or better yet, take a rubber sheet and make it big in Philadelphia, you know you're rich in Philadelphia, you have an infinitely big bed and you stretch it out, it's not really a language there, so of course I am, but that's the The only thing I play with you is that we don't know how to do math, but this makes me think that the term infinity doesn't make sense now, well, no, it is, it's very, it doesn't make sense to a certain extent. sense, it's going to get frustrating for me here, no, no.

I'm going to say I'll give you an example that I never thought I'd do on this show, but okay, this guy Hilbert was a very famous math quest. He invented this paradox that shows that infinity doesn't make sense when you think about it. language, it's him, call it, we call it Hilbert's hotel, you'll have this thing that will blow your mind, okay, so you go, let's say, you go to Las Vegas to a big baby hotel, okay, and you walk in and you said like a room and They say, well, all the rooms are

full

and it comes out, okay, go, I'll go, someone said: no, no, no, no, no, this is a big inflamed hotel, we can fit you in how well it takes a person to remember that he put it number one. in room number two person to remember to put it remember three three even four and I do that and now room number one of these Tyco I'll do it at the same time but I don't but even that's hard so it's okay so I'll sleep in the lobby, yes, yes, nobody wait.

I'm going to make it even worse, so you walk in with a Catholic family, an infinitely large family, yes, and you say: I have a room for myself. in Philadelphia, a big family and they say, oh no, no, we can fit in, you know how I take person number one for him, put him in room number two, remember room number three to room six, remember four and eight, now only the even numbers are occupied and all the odd numbers are free so you can fit into your family unit. That used to be mine. I didn't hear that, but he used my favorite fact to ruin whether it was mine, so there were a lot of even numbers. like odd even numbers together, yes, exactly because infinity is a very subtle concept and mathematicians have a way of dealing with it, but if you don't handle it care

full

y, you come to it as a concept, even though infinity is just a concept, good.

You brought up an interesting interesting question: physicists don't like infinities, well no, there is nothing good physical, but what if space is infinitely large? well, what if and what if I thought that we are going to solve it, yes, we are going to try, but I have to admit that the possibility has to be a good concept, our things raised much more, there is no more concept and concept than the good infinity, but well, you know, example of it because you have to do it because you can't you can't you can't say I, a number that's even getting close, you know, but I can say it, but as you know, I know the concept well, but I can't say that one, no, but number one is a concept, but it uses a concept that you can say, well, I see. one is, yes, we could be mathematicians, no, but mathematicians have discovered ways to work with infinity as a number or different types of infinities in ways that give sensible results, so as a numerical concept, it says that it is known, does it make any sense, yeah like well defined like a million or a billion or a billion done is just weirder, a lot weirder, so you're basically laying out the possibilities, yeah, to work backwards, so you have all the possibilities laid out, yeah, and one of them is true and well one of them is true for us yeah, that's what I mean and this and physicists have been talking about this recently if there are an infinite number of universes, which we think is quite likely yes, this blows my mind if not, again no, but then it's even worse, okay or even if our universe persists for an infinite time, but let's take infinite universes, there is a universe in which we are having this conversation, but you're telling me physics, now I'm telling you jaw and more about that, but there are an infinite number of universes when this conversation is exactly the same except for one word, yes, there is a picture exactly the same, I'll get it weird, yeah , but it's just a concept, like what if it's true, but what. if it means many because we will never know because we live in a universe because when we know the nature and possibility of space and time and infinity those words no longer mean anything in a normal sentence because because you are using them the way I I know them and accept them in this world, but they are no longer true.

Well, there you hit the point McKee and that's why people get so angry when I wrote the universe from scratch, especially religious people. because I point out that science has shown that nothing is not what people once thought it was is the word means something very different we change the meaning of nothing just let me change the meaning of something and they say but you can to change the meaning just like We changed the nature of time when we discovered that the speed of light was a constant and the disk resonated a little bit, you can say wait, you can't change what we mean by anything and I say: Call that learning, okay, it means that I don't know because it doesn't help me, but the point here is that, as I described in that book, there are many different types of nothingness, there is a nothingness of the Bible that is in an infinite void. space there, but there is nothing in it, but that is nothing because where is the space, what happens if you get rid of the space?

I have to be very careful and physics has shown that they say it appears and disappears like anything. This is what I can't understand because I can't understand it. I can't understand my definition of the concept that I can't imagine that there is nothing around this atom to expand. Well, you do it because I declare it to anyone. who is even less in line than me and I'm not right anywhere no, no, you don't mean a void, no, I mean, there is nothing, there is no void, I don't even know, no, yeah, well, a void for some people. the vacuum is nothing, but I would say it is definitely nothing because there are a lot of things that of course are actually spaced out, even thrown away, there are a lot of things in the vacuum cleaner, there are a lot of things there and then you work with a lot of things here well, of course, let me give you the big point, I mean what we have learned, that the universe, the dominant things in the universe, are nothing, yes, because I empty the space, you take a piece of space, get rid of everything in it, yes. it still weighs something and we don't have the slightest understanding of why it still weighs something, how do you say Wyatt? what gravity then it probably all comes down to grammar it all comes down to the ground what is gravity it's a force like that it's on I see again I thought it was an apple that fell on your head yeah I know right I thought that gravity was a force created by matter and that's what we used to think and that's what Newton would say and no, it's good, it's never nonsense, that's one of the big misunderstandings of 2017 exactly, but no, but, I'm like, unlike the whole, yeah, exactly right, but, unlike the different culture, science doesn't do what things don't go out of style, so Newton is just as true now. as it was then, if you want to hit a baseball or throw a cannon, take a rocket and go to the moon, Newton works, that's the point, scientific revolutions don't work in the world and in everyone and everyone.

Yes, that's what we learn about the universe. The strangest situations will never change. I will never have a ball. Whatever I learned about quantum physics. I'm never going to have a ball here and say, "I'm letting him go. He's going to fall." It's always going to matter what we learn, the law that says it's going to fall will always be true, so why don't I just call these concepts and these possibilities correct and they don't interfere with our contingent laws and get some space and see, why not just call him God? You can but it's a but you know the reason you do it is because you don't want to think well, yeah, I'm using God exactly, God is just for a lot of people did their scary things with concepts, but why can't I?

Why can't I just say God? because because and I just mean all the things that you said, yeah, you can say that, but then you can send it, that basically says okay, so I give. try to explain or understand because there are many things that go to my head, it hurts, it's okay and I never thought of you in a religious way, you know, you made me believe that my life was complete, yes, thank you for this program, you weren't. religious and now you are I think it's a good way to end it's yes, I've converted you that was great the
