Alright Paul, so you've gone through and you've used physics to calculate that all of this stuff when it collapses gravity should form a big disc, but it's a really big disc. It's a lot bigger than our solar system. Yes, everything comes down to some sort of spinning disc of gas, but spinning disc of gas is half a lot here across. So yeah, thousand times bigger than our solar system, my theory doesn't explain how, there's just too much angular momentum, these things are rotating too fast. Now when you did your calculation, you made some approximations, you assumed everything was nice and orderly, and yet we've seen those giant molecular clouds look like train racks. So it's going to be messy, it's not going to be nice and orderly like you assumed. So I really think what you should do is to use computer simulation to look at this. Yes, when things are really messy and complicated, call it a computer. Luckily Matthew Bayton University of Exeter has done this for us, and here we've got a supercomputer simulation of the collapse of a giant molecular cloud. That isn't much more than our orderly. So you remember the same press, we've really talked about how you do n-body calculations, you have a whole bunch of imaginary particles and you watch them moving on mutual gravity. This is a bit more complicated than that because you also have to allow for gas pressure, gas cooling and gas temperature. So what he did was he put a sphere of gas and gave it some random motion, random density. So he's now following these things as they move. And these white dots are where they actually turn into solar systems, what he actually does are the simulation, whatever the gas gets within about 30 or 40 astronomical units, the size of the solar system that just counts as a dot. It turns into what he would call a star or something. Yes. So each of these dots probably does have a spinning disk around it, but they're much smaller. So the way you get rid of the angle of a momentum is by having these different dots orbiting around each other. So you get a lot of angle of momentum in two stars, a binary star or a cluster of stars orbiting around. That mobs up most of the angle of momentum, leaving only a little bit left in each of these individual dots to form a spinning disk. All right. So what you're saying is that each one of these spinning disks is going to look like a sensible, mini-proto solar system of our own with a sort of a proto-sun in the center. And then other things which presumably are where the planets are going to be formed out of? Yes, this is the idea. Because you can mop up most of the angle of momentum in a realistic simulation in the relative motion of the stars, that means you get a spinning disk of gas which could be much smaller. And so this is called a proto-planetary disk. And this is an artist's impression of one of these things. Okay. Well, artist impressions are great, but I'm kind of into reality. So if we go out and we look at one of these molecular clouds that's kind of advanced, we should see things like this if they're real. And indeed we do. Here are some pictures of the Orion nebula. And you can see these disk shaped blobs here. I mean, it's zooming on that one over there. It's like some sort of evil eye, I guess. Okay. I like it. So this is the proto-sun. And then that's the stuff that you think the planet's going to be formed out of. Yes. And you can see more of these things. These are what we call daydream disks. In this case, we've blocked out the light from the center with a chronograph. I was obviously going to tell us to block out the light stopper from blinding you. And you can see, in this case, Ed John. Yeah, they're very long and thin. They really are a little disks. They're almost like a little record going around the star. So these things really do seem to exist. But there's a problem. I mean, we've got all this gas raining down. And because of the relative motion of the stars, you can mop up the angular momentum and what's left will form the spinning disk. But most of the mass in one of these disks is not going to be in the center, at least to begin with. It's going to be out of the spinning disk. Somehow we need to move most of that mass into the center. Because as we know in our own solar system, the mass is not on the planets. The mass is in the middle. Right. So we want to have a sun in the center, not on the outside in the planet in the center, which seems to be naturally what you might get. Yes.
