• Everybody watching this video lives on Earth, at least hopefully

• Which means that you know the Earth

• Makes one complete rotation every 24 hours

• The speed of this rotation is what defines a day

• But what would be some consequences if this speed doubled to once every 12 hours

• How would this affect our daily lives?

• First it's important to understand that the Earth spins at different speeds

• Depending on where you are standing

• At the Equator, Earth spins at a speed of 1670 kilometers per hour

• The farther away you get from the Equator, the slower the spin you experience

• So the Poles are where Earth spins the slowest

• If Earth immediatedly began spinning twice as fast

• The first thing you might notice is a little bit of weight loss

• Because the centripetal force of Earth's rotation is stronger at the Equator

• Everything weighs slightly less here than at the Poles

• Currently, if you weigh 45 kilograms at the North Pole

• You would weigh 156 grams less at the Equator

• With Earth spinning twice as fast

• A person that weighs 104 kilograms at the North Pole would weigh about half a kilogram less at the Equator

• Which is slightly more noticeable

• But a much more obvious effect would be the lenght of our days at 12 hours instead of 24

• Days being half as long means that years will have twice as many days

• 730 days to be exact

• So we would need to create a new calendar pretty quick

• You'd have to adopt a new sleeping schedule in order to fit in your work and school during your daylight hours

• So instead of getting 8 hours of sleep per night

• Most people would probably be getting 4 hours of sleep

• But sleep twice as often

• If you're like me and stay up all night, well, good luck

• Animals across the globe would also struggle to adapt their instincts

• Specially nocturnal animals that would have to hunt at night with half the time they are currently used to

• Animals that couldn't adapt would likely go extinct

• Also, hurricanes would be dramatically stronger

• Winds at the Equator would be deflected further eastward

• And it would spin up hurricanes to faster speeds whenever they form

• But that's not even close to the worst thing that would happen to our planet

• The worst part about an Earth that spins twice as fast

• Would be the water in the oceans concentrating around the Equator

• And receding from the Poles

• The higher centrifugal force would pull 100 meters or more

• Of ocean water from the Poles here

• And this would be wildly catastrophic

• Almost all of Equador, Colombia, Venezuela, Brasil

• Kenia, Indonesia, Malaysia, Singapore and Northern Australia

• would be totally underwater in this scenario

• Forcing hundreds of millions of people to move either North or South

• Only the highest peaks like the Andes in South America

• Or mount Kilamanjaro in Africa would remain above the raising waves

• Which would form new islands out of what used to be entire continents

• Africa would probably be split into 2 different land masses

• With a few islands scattered between them

• While South America would just be greatly reduced in size

• One final reason that it would suck to be in the Equator during this scenario

• Is that the less weight experienced would cause the air to be very heavy with moisture

• The whole region would be shrouded in a very dense fog

• And would be subject to constant rain

• Combine this with a super powerful new hurricanes

• And the Equator would be an extremely hazardous place

• This means the Equator would be a significant geographical barrier

• Between the Northern hemisphere

• And what remains of the Southern hemisphere

• One final consequence would be at least a momentary loss

• Of satelite-based technology like GPS

• Geostationary satelites orbit the Earth at a speed that matches the planet's rotation

• So that it can stay in place over the same spot on Earth's surface

• If Earth's rotation speeds up then the satelites won't be in the correct positions anymore

• Which means everything from GPS, TV broadcasting

• As well as military and intelligence communications could be disrupted

• The speed of Earth in reality is constantly fluctuating

• 4.4 billion years ago, our planet spun at a rate of 4 hours per day

• And during the time of the Dinosaurs

• It spun at 22 hours per day

• Earth's rotation is actually slowing down every few million years

• Because of the gravitational Pole of our Moon

• And that slowing trend will continue on

• For billions of years to come

• Earth's rotation probably won't be getting any faster in the future

• Unless we get hit by something enormous that we don't see yet

• But then at that point we'd have a bigger issue to worry about anyway

• If you have an issue that you want to learn how to fix

• Like learning how to animate your own videos for YouTube

• Then you should checkout the Mastering Illustrator class on Skillshare next

• Almost 2 years ago I created this channel

• And I literally had no idea what I was doing with animations

• I didn't learn how to do any of this in school

• I learned watching online tutorial videos instead

• Just like you may be trying to do now

• No matter what you want to learn how to do

• Skillshare is a site that concentrates

• All of these tutorial videos in an easy to find place with qualified teachers

• And a structured learning format that eases you into things

• The course i'm recommending you checkout now

• Is taught by an actual design studio that has worked on artwork

• For Star Wars, Back to the Future and South by Southwest

• And the first 500 people to sign up to Skillshare with this link in the description

• Will get a 2-month free trial to watch this course

• or any number of the other 17.000 classes

• In subjects that range from graphic design to videogame development

• A premium membership usually begins around \$10 per month

• For unlimited access to all courses

• But in those free 2 months you could easily learn the skills

• That you need to start your new hobby or business

• Just like I did with this channel

• So ask yourself right now

• What skills have you been putting off learning recently?

• What project have you been dreaming of completing

• But you aren't sure if you have the skills needed to do it?

• Why shoudln't you start right now

• and sign up to Skillshare using the link below?

• You have nothing to lose and a valuable lifeskill to gain
