What would happen if the Earth was replaced by a black hole?

The same gravitational effects that produced spaghettification would start to take effect here. The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

What would happen to the moon if the Earth was replaced by a black hole?

If the earth is changed into an earth-mass black hole, the only effect on the Moon’s orbit will be a change in the back-reaction on the Moon of the tidal forces that the Moon exerts on the Earth, as well as subtle changes in the Moon’s motion due to quadrupole corrections to the Earth’s gravitational field.

What would happen if our Sun was replaced with a same sized black hole?

Earth Will Not Be Sucked In by a Black Hole Well, once you know if the sun is replaced by a black hole there will be no life. With the same mass as the sun, the movement of the planets around it will remain in its orbit.

What would happen to Earth if the sun was replaced with a black hole the same mass same size?

If our Sun was suddenly replaced with a black hole of the same mass, Earth’s orbit around the Sun would be unchanged. Hence the Earth would have to get very close to get sucked into a black hole at the center of our Solar System.

What would happen if the Earth had a large core?

The iron core and liquid mantle would also be 10 times larger, and with more gravity acting on a larger mass, the pressure beneath Earth’s surface would increase. But if the core solidified, the currents would stop and the magnetic field could be weakened or eliminated, Barnes said.

What would happen if the moon turned into a black hole?

If moon were to be replaced with a black hole of equal mass, nothing will happen at first (no effects on the orbits as the forces are the same). Gravitationally (and thus tides, etc), there would be no change as the mass of the black hole would remain the same as the moon as ither answers have mentioned.

How would Earth become a black hole?

If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. If, somehow, the electromagnetic and quantum forces holding the Earth up against gravitational collapse were turned off, Earth would quickly become a black hole.
