What If a Black Hole Ate the Sun?

it's almost as old as the universe and as massive as 34 billion suns it eats stars for breakfast and now it's about to consume ours [Music] behold the great and powerful black hole with the catchy name j2157 if it came close enough to our solar system how fast would it destroy us how would it all go sideways for our sun and how exactly would this monstrous black hole end all life on earth this is what if and here's what would happen if a black hole swallowed the sun black holes are scary enough they form when big stars explode in a supernova and then collapse in on themselves the most common black holes the stellar ones are only 16 kilometers in diameter but they have the mass of a star at least 10 times more massive than our sun crammed in them all that mass compressed into such a small diameter makes black holes extremely dense if you came too close to a black hole's vicinity beyond its event horizon its extreme gravitational pull would turn you into a spaghetti noodle but there are black holes so massive that they make stellar black holes look feather light these are called super massive black holes these monstrosities lurk at the centers of galaxies and take up space roughly the size of our solar system but most of them don't even get close to the size of black hole j2157 j2157 is the fastest growing black hole in the known universe and it's the second largest one its event horizon has a radius of 670 astronomical units which is comparable to the distance between the sun and neptune multiplied by 22. whoa if that's not scary enough j2157 holds the title of the hungriest black hole we know to stay in good shape it gobbles up matter at a rate of about one sun per day now take this monstrosity and bring it closer to our solar system you can imagine how that would play out if j2157 could replace the supermassive black hole that sits at the center of our milky way galaxy to us on earth it would look 10 times brighter than the full moon that's because of its incredibly large accretion disk the matter the black hole collected on its way to us and because it always needs to be the center of attention this monstrous black hole would outshine most of the stars in the sky if a black hole under 100 million masses of our sun entered our solar system it wouldn't swallow the sun in one go it would gradually start pulling matter from our star until all that's left of it would be a cloud of gas in that case you could expect lethal amounts of cosmic radiation headed toward the earth but that's not how j2157 likes to deal with things a black hole of that size and mass would devour the sun in a moment but losing the sun would be the least of our problems our planet could be torn apart by the tidal forces from the black hole consuming our sun or it could be bombarded with an unthinkable amount of cosmic radiation or it would disappear into the black hole's event horizon along with the rest of the solar system either way you wouldn't get out of this alive but no matter how big and scary j2157 is remember that it sits at a safe distance of 12 and a half billion light years away from us i'd say we're pretty safe here now if you ever plan to visit a black hole you'll need to look into some survival tips and we have a new show for you about just that to help you survive whatever awaits you you
