What If We Lost Gravity for 5 Seconds?

[Music] the sky is falling the sky is falling get a grip the sky isn't falling it's getting sucked into outer space and so are all the oceans and the trees and cars and roads and bridges and the Earth's core and you so get a grip and hold on tight hang on K you're in for a while ride this is what if and here's what would happen if we lost gravity for 5 seconds unless you're an astronaut you probably don't spend a lot of time thinking about gravity we all take gravity for granted and it would be hard not to aside from a tiny sliver of the world's population most humans don't know a life without gravity from the universe to our solar system to each planet all the way down to our own bodies gravity holds everything together but since we tend to see gravity as a given it's hard to imagine just how helpless we would be without it until it's actually gone gravity is an attractive force between any two masses the greater the mass the greater the gravity the greater the gravity the stronger the pull gravity is the re reason why Earth rotates around the Sun why we experience high and low tide and why we can walk on this planet without floating away most importantly though gravity secures our atmosphere holding in the air we need to breathe in fact there are a lot of things we can thank gravity for so many though that if we tried to list them all here we'd probably end up with a video longer than Titanic so just to give you an idea of how important Gra gravity is in a really really short amount of time we're going to take it away from you but not for too long just 5 seconds are you ready with the world still spinning at its usual 1,600 kmh speed everything that isn't secured firmly to the ground would go flying cars boats trains planes well obviously but not like they normally do more like this the Earth spins faster along the Equator so the impact of zero gravity would be felt hardest there that means that in just 5 Seconds you could be blown as far as 2.3 km in any direction and not just you there will be plenty of people objects and animals to look out for not to mention trees soil and midair floods from the world's ponds lakes rivers and oceans at the same time the gas es in the atmosphere would drift out into space not only are we now losing huge amounts of oxygen but the sudden and sharp drop in air pressure would instantly shatter everyone's inner ears and then there's the planet itself which is literally held together by gravity without gravity the pressure of the Earth's inner core would cause the planet to expand it's not like 5 Seconds without gravity would cause the world to explode but even a 5 second expansion of the Earth's inner core would cause some major earthquakes and Trigger huge volcanic eruptions add one more item to your list of dangerous things flying through the sky lava out in Space the planets in our solar system that normally orbit the sun would instead start drifting away from it Earth would follow its neighbors at a speed of 30 km/s in just 5 Seconds it would have traveled 150 k km that's not far enough for our planet to be out of the habitable zone but how habitable would Earth be after five deadly seconds without gravity when gravity was restored you'd hit the ground hard if the impact didn't kill you or if you weren't crushed by a heavy object you would still be severely injured my back oh my back hopefully you'd catch your breath in time with gravity pulling oxygen back down to earth and bringing the atmosphere back around the planet but there would still be earthquakes and volcanic eruptions as the Earth's core becomes compressed again and there would still be massive flooding due to the significant displacement of the oceans the number of casualties would be astronomical not just from flying debris lack of oxygen or simultaneous natural disasters but because in those 5 Seconds without gravity the Earth's crust literally opened up and swallowed several major cities so yeah a lot can happen in just 5 seconds and that just goes to show how essential gravity is to life on Earth and Beyond you may think you're special and you most certainly are but just remember that you're part of something bigger than you and that's what keeps you grounded but don't sink too low can you imagine how heavy you'd be if Earth's gravity doubled well that's a story for another what [Music] if
