What If the Sun Disappeared Right Now?

[Music] what would happen if the Sun disappeared the Sun is the closest star to earth only thanks to the Sun life as we know it exists it's light hits the surface of the planet making it warm enough for living organisms to develop and live on plants convert solar energy into chemical energy they give us oxygen to breathe and so you can go to the beach and have a tap but what would happen if the Sun disappeared right now what do you think well I don't know but you know let me take a wild guess um it would get dark well would we even notice that how long would we be able to survive without the Sun would it be cold enough for the Russians to consider moving to a different planet well in this video brightside decided to take a look at this hypothetical situation and imagine what it would be like to live on earth without the Sun therefore well let's go to the dark side counting down from number five we would have no idea at first seriously the Sun is eight light minutes away from Earth a light meant it is a distance that light can travel in one minute for example if you were on Mars and your friend were here on earth that's imagine you both have good enough eyes to see each other if you wave to your friend he would see you only in about 30 minutes depending on how far Mars would be at the moment here's another example if 65 million light years away there were some advanced creatures that had powerful telescopes they would be able to see dinosaurs walking on earth or rather making their last steps because that's when they went extinct approximately the sunlight reflected by earth would need 65 million years to reach the creatures eyes or whatever they use to see things as we know nothing literally nothing in the universe can travel faster than light so right after the Sun disappeared it would take 8 minutes for this good news to reach us even the gravitational pull that the Sun has on our would also end only in 8 minutes so the earth would continue orbiting the spot where the Sun had been as if nothing happened but for only eight minutes after that our planet would start to fly in a straight line and that's when mass panic would probably start as people try to return those solar panels they just had installed number four it would be very dark hey yeah I was right man yes you were those are on the night side wouldn't notice anything at first but only until the moon would disappear as it would have no sunlight to reflect other planets would vanish into darkness one after another as the last bits of reflected light would reach our eyes distant stars would be our only source of light outside the planet it would be quite enough to be able to see around a bit photosynthesis would stop so plants would no longer be able to produce life-sustaining oxygen it might sound like a serious issue but it isn't collectively all living humans all insects and all animals would still have enough oxygen to breathe for about another thousand years there would be a much bigger problem though yeah especially if you own the sunglasses shop you know I didn't think of that anyways number three it would be extremely cold without any source of heat earth would cool down very quickly within just the first week the planet would be about 32 degrees Fahrenheit or zero degrees Celsius it doesn't sound that scary right especially taking into account fuels that we have we would most likely get along fine without the Sun for the first few months but by the end of the first year without the Sun it would be so cold that the only way for us and other organisms to survive would be to go underground as deep as possible the closer you would live to the core the better chances you would have but that would involve a lot of digging seriously speaking though none of us would be able to live if we didn't find a way to leave earth number two oceans would freeze over well this just keeps getting better and better because of the extreme temperatures the surface of oceans would become a giant skating rink but only the surface it's not that the ice would be thin and you'd have to think twice before jumping on it nope the thing is that is has been estimated that liquid water would continue to exist at the bottom of our oceans for billions of years it wouldn't freeze because the Earth's core would still be very hot and number one some organisms would be just fine now sorry humans are not among them only the smallest creatures such as those that live in the Mariana Trench could survive the disappearance of our star they don't require photosynthesis they convert heat into the energy they need so as long as the water would be liquid the organisms would be alive just imagine our planet all frozen traveling through the universe for billions of years still conserving what is left of life before the Sun left us maybe one day we'll come close enough to a different star and get into its gravitational pull and star orbiting around it in this case the ice would melt and the planet would heat so those microbes would have a chance to evolve into other types of life but in such conditions the chances that humans would appear as a result of this evolution are slightly bigger than zero on the other hand the leftovers of our civilization would most likely still be there other forms of intelligent life could see what we were like you see after all the sun's disappearance might not be that terrible yeah if you're a microbe well another comforting thought is that the Sun will die only in about five billion years from now so we have plenty of time to look for a new home and that's enough of the dark side did we forget any other dire consequences of the son's disappearance tell us in the comment section below don't forget to

Isn't that straightly taken up from Vsauce's video?
