If the sun were to magically turn into a black hole of the same mass, the consequences would be catastrophic for Earth and the entire solar system. The gravitational pull of the black hole would be much stronger than that of the sun, causing all planets and objects in the solar system to be pulled towards it. This would result in the destruction of the solar system and the end of life on Earth.
When a black hole collapses, it shrinks in size and its gravitational pull becomes stronger. This process is called gravitational collapse. The consequences of this collapse include the black hole becoming denser and more massive, leading to an increase in its gravitational force. This can result in the black hole consuming nearby matter and energy, and potentially emitting powerful radiation and jets of particles.
If the Sun collapsed into a black hole, it would be about 3 kilometers in diameter.
A black hole would have more thermal energy than the moon.
When a black hole collides with a white hole, it is theorized that they would cancel each other out, resulting in the release of energy and potentially creating a new type of cosmic event.
From Earth, a black hole would appear as a dark, featureless region in space, surrounded by a glowing ring of hot gas and dust spiraling into it. The black hole itself would not emit any light, making it invisible to the naked eye.
If the Earth magically became a black hole, the moon and other satellites in orbit around Earth, would be literally ripped apart into tiny bits and swallowed by the black hole.

You would die quickly, either before, or after, falling into the black hole, depending on the mass of the black hole.
It depends on how much mass the black hole had. If the black hole had the mass of our Sun, it would take a long time, around a hundred million years. For a really big black hole, with a hundred million times the mass of our Sun (as is thought to exist in the centers of some galaxies), it would take about ten thousand years. One thing to remember is that at such great distances the gravity of a black hole acts like the gravity of anything else with that mass (e.g., if the Sun were magically turned into a black hole with the Sun's mass, the Earth would orbit as it always does. We'd just get cold without the Sun's radiation!). The weird effects you read about for black holes happen only very close in.
If it gets close enough, it will fall into the black hole. Of course, any object might also pass at a safe distance, with no consequences.
If you jumped into a black hole, you would be stretched into human spaghetti.
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
It would get completely destroyed. the mass of the black hole would increase.
The black hole's mass would increase by an insignificant amount.
No, they are not the same. A singularity would be inside a black hole.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Nothing, not even light, can escape a black hole. So Earth would get caught into the black hole's path and we would be sucked up and crushed to oblivion
