What's the gravity of a black hole?

The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now. The sun will never turn into a black hole. Are black holes like whirlpools? A spinning black hole is more like a whirlpool than a pothole. The swirling water in this analogy is spacetime itself. It's pulled around as the black hole rotates. This region of twisted spacetime is called the ergosphere.

Then, what is vortex effect?

A discussion is given of the interaction between. the rotational field associated with such vortices and bubbles in liquid. flow or droplets in vapor flow. This interaction is called the wall-vortex. effect. Are ocean whirlpools real? In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. Smaller whirlpools appear at river rapids and can be observed downstream of artificial structures such as weirs and dams.

Moreover, can you vortex water?

When the water level and pressure drop low enough, the water surface can hold back the water and stop the flow completely. If you spin the bottles around a few times, the water in the upper bottle starts rotating. As the water drains into the lower bottle, a vortex forms. Then, are whirlpools natural? Powerful ones are often referred to as maelstroms and are mainly common in seas and oceans. Smaller whirlpools are common at the base of waterfalls and can also be observed in man-made structures such as dams and weirs. In oceans, they are mainly caused by tides and are capable of submerging large ships.
