![]() When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation. They lie in wait until a hapless star wanders by. But even then we'd be uncertain about large-body collisions with the Earth rendering the crust too unstable to allow survival. Hubble Finds Hungry Black Hole Twisting Captured Star Into Donut Shape Black holes are gatherers, not hunters. We'd all die fairly rapidly because of a global ice age and finite food reserves, unless someone wants to start a geothermal (relying on the Earth's heat output) community sufficiently well equipped. But to simply say the Earth would start to drift inwards would be to neglect the effect on the whole solar system, which would be chaotic, and difficult to predict, as precise measurements of the changing relative position and mutual influence would require such precision as to be harshly taxing even on the world's greatest supercomputers. The effect would be to, albeit slowly reduce the earth's distance from the sun as the effect of angular momentum against the sun's gravity would no longer be affected by the continual force of the solar wind and the stability of its orbit would be thrown into chaos by the same effect occuring to all other planetary and smaller bodies such as comets and the asteroid belt: Here article 2198 THe Oort cloud may be too far out to considder in the short term. The earth would no longer be subject to the solar winds which exert several (3) forces on the magnetosphere in a quite complex relationship. As it exhausts its hydrogen fuel, our Sun will start burning helium, swell in size and briefly become a red giant (giant in size, though not. Assuming the sun's gravitational field remained constant at Earth's distance from it (1 AU), and that we were not subject to the Black Hole's polar radiation. No, our Sun is much too small to become a black hole. ![]()
