I know this sound weird but What will happen if the earth fell into the sun some kids say why does the moon not fall down well thats a beautiful question the moon is constantly falling but what will really happen if the earth stopped its orbit and fell into the sun well if it did we would approximately have 64 days until the earth gets destroyed.
Day 0: The earth begins its journey into the sun
Day 6: After 6 days of falling into the sun the earths temperature rises 0.8 of a degree you wont feel the heat yet but you will soon.
Day 21: the earths temperature has risen 10 degrees now the earths experiencing a global heat wave.
Day 35: We are now %20 percent of the way to the sun the suns intense and the global temperature is 58.0 degrees the earth now exceeds the historical temperature in Death Valley CA.
For most people now cant survive either the airconditioners are failing or the powers being tapped out.
Day 41: we have now crossed venus's orbit the global temperature is 76 degrees too hot for the Sahara Desert Ant but the pompeii worm is still thriving which they can survive up to 80 degrees.
Day 47: We just left the habitable zone the temp now exceeds 106 degrees too even hot for us to live. but the pompeii worm is still thriving underneath the earths crust where the earth prevents boiling water from accessing the crust.
though tardigrades although known for water bears are the most earths extreme survivors at this point they know something is awry they go underground and keep %1 percent of water which can last up to a decade.
Day 54: Farewell dear Tardigrades you outlived us all they lasted from absolute zero to 151 degrees to hot for you.
Day 57: we are now the closest planet to the sun the earths temperature is now 200 degrees
Day 64: we now reached our final day the day starts of at an extreme 800 degrees the suns gravital force is so immense that it pulls the front of the earth towards the sun and crosses an imaginary line called Roche Limit the earths temperature hits 2000 degrees by midday and once the sun pulls it in at an extreme force the earth rips into smaller pieces of magma and rock.
THIS IS ACTUALLY NEWTONS THEORY.
