burgess Posted June 27, 2014 Share Posted June 27, 2014 What happens to earth planet orbit, If the sun collapsed to become a black hole? May be a silly question but i want the answer, please explain Link to comment Share on other sites More sharing options...
Nicholas Kang Posted June 27, 2014 Share Posted June 27, 2014 Our sun has one solar mass and it wouldn`t evolved into supergiants. The Sun will finally evolved into a red giant and then when the He fuel runs out, a planetary nebula will take place. What is left will be just a white dwarf which finally shrinks and fade off to form a black dwarf. Our Earth will be "evaporated" as the Sun`s expand due to core collapsing inwards and the Sun will eventually reaches beyond Venus orbits and maybe Earth or beyond. So, there might be a possibility of Earth either being engulfed by the Sun or evaporated due to the close distance between Sun and the Earth. If you treat the Sun as a supergiants like blue, bluish-white or white supergiants, they will eventually explode in a spectacular supernova or even hypernova for large stars, then if the core left behind is more than 3-4 times of solar mass, the strong gravitational force will continue to crush the neutron star which is supposed to be formed if the core is less than 3 times of solar mass and until a point know as singularity. It marks the border of Physics/Modern Physics. Currently, Stephen Hawking`s new paper suggested that the event horizon which marks the point of no-return can`t be found, so there is no black hole, instead he called it a grey hole. Because the paper is short, scientists still need further examination of our universe to confirm Hawking`s theory. If you treat the sun as supergiants which are going to explode in a supernova, then the sun would actually engulf the Earth before turning into Wolf-Rayet Stars or WF Stars, which mark the moments before a supernova take place. 1 Link to comment Share on other sites More sharing options...
swansont Posted June 27, 2014 Share Posted June 27, 2014 What happens to earth planet orbit, If the sun collapsed to become a black hole? May be a silly question but i want the answer, please explain What would happen to the gravity of the sun if it suddenly became a black hole?
