Brian Cox Reveals Why the Earth Is Round | This Morning

forces of nature yeah so so in what areas what are you looking at well the idea is that if you look at the the world that we see so so there the green leaves the blue sky spherical planets all those things telling you something about the deeper structure that underlies nature so even life next weeks is about the origin of life so it's how did we you know we feel living in Giza is a very special thing but it's a property of matter this stuff in the earth was once just a dead world when it formed four-and-a-half billion years ago and at some point that matter came alive and you go to some really black far-flung destinations and as you can see that from that tiny bit that we should I mean it's beautiful like it's beautifully shot and you see some incredible things that you wouldn't necessarily get to see yeah there's the idea to send film crews out in its of the way you mentioned David Attenborough le the way these programs work where a film crew can go in for four months even film some of them spectacular and we saw that wave on that click through the Amazon it's in a wonderful incredible tidal wave that goes up the river and you see in the film that someone spends their life surfing it so there's kind of his whole thing is to wait for this wave and surf into the jungle of it so it's it comes when when the moon and the Sun release I think it's about once every couple of months or something like that the power rock acts cold well you're you're not because they go out and they sit for months waiting for something to happen the right thing to happen you're not there all the time you're in this one less on yeah I mean that was the idea to film these beautiful things did you can't if I'm there it's kind of you can't spend all that time we have different crews out at the same time filming things and then the idea was to try and stitch it together essentially you ask the question what is it what's the biggest the tallest mountain you could make on a planet like the earth what what sets that so you've got the Earth's gravity which depends on and its mass really how much stuff is in the earth it's pulling it down pulling it down so you can imagine there's a force on the ground and the bigger you build the thing the more the force is and you can work out well how what is it when that force overwhelms our strength the rock and it starts to sink there's actually on earth in Mauna Kea which is one of the Hawaiian volcanoes it's actually taller than Everest have you measured from the surface of the sea floor and that's sinking so that's as tall yeah so it's two that is as tall as they go they could go so if you've got a big enough planet with enough gravity essentially then then anything that gets too big or sink and gravity just works you know it doesn't care which angle you're at circle the two a sphere if it's big enough and then you look out into the solar system a little moons about less than about 150 miles across or something like that I've not got enough gravity so there are miss shape it's called the potato radius so you get potatoes you can say that one potato well the way that I demonstrated he just wanted to get so the way that we demonstrated it in the program is st. so what am i doing if I want to make that into a bowl then I have to apply in a force to overcome the if I don't apply the force then it'll stay like some sort of mistake you know potato shape so that's what gravity is doing really it's acting as a as a force that's squashing it down and and and it'll turn it into a sphere because it acts the same in every direction hello youtube for more of the same and just click here and don't forget you can subscribe for even more of these amazing videos exclusive to our channel and things happen your beer bottles you cut yourself I accidentally punched him in the face once you know it things happen I mean because you throw up on stage didn't just I'm sorry story the punching actually was worse for both show you
