Dropping a Black Hole from Tower of Piza

In summary, the conversation discusses the concept of objects falling at the same rate of acceleration regardless of their mass. However, the question is raised about the effect of a black hole on this principle. The conversation also delves into the validity of the assumptions behind this concept.

I get that if you drop a tennis ball and a 10 lb medicine ball from the top of a tower they will both reach the ground at the same time. But what if I dropped a softball and a black hole with the radius of a softball (and the mass of a small planet)? Wouldn't the tremendous gravity of the black hole pull that much harder on the Earth, thereby closing the gap between them faster than the gap between the Earth and the softball?

What does Newton's second law say about the acceleration of the BH?

Does the answer bother you?
What are the assumptions in the statement "all objects fall at the same acceleration"?
Are the assumptions still valid here?

The softball would fall into the black hole, and not down.

1. What would happen if a black hole was dropped from the Tower of Piza?

It is currently not possible to create or manipulate black holes, so dropping one from the Tower of Piza is purely hypothetical. However, if it were to happen, the black hole would likely continue to fall towards the center of the Earth due to its immense gravitational pull. It would also cause significant destruction and chaos in its path.

2. Would the black hole swallow the entire Earth if dropped from the Tower of Piza?

No, the black hole would not swallow the entire Earth. While it would cause destruction and chaos, the black hole's size would likely be too small to swallow the entire planet. It would also eventually dissipate due to Hawking radiation.

3. Could the black hole be stopped or slowed down if dropped from the Tower of Piza?

No, the black hole's gravitational pull would be too strong to be stopped or slowed down by any known means. Its trajectory would be determined by its mass and the force of gravity from the Earth.

4. How would the black hole's fall affect the Tower of Piza and its surroundings?

The black hole's immense gravitational pull would cause significant destruction to the Tower of Piza and its surroundings. It would likely collapse buildings and structures in its path and cause massive disruptions to the surrounding environment.

5. Is it possible to create a black hole strong enough to destroy the Earth?

No, it is not possible to create a black hole strong enough to destroy the Earth. The minimum mass needed for a black hole to destroy the Earth is approximately the mass of the planet, which is not achievable with current technology. Additionally, even if a black hole of such mass were to exist, it would not be able to destroy the entire planet as it would eventually dissipate due to Hawking radiation.
