Ah, what a fantastic question, friend. You see, when a supernova explodes, it can leave behind a great remnant like a spinning neutron star or a black hole. Black holes are actually formed when massive stars collapse under their own gravity during a supernova, creating a wondrous and mysterious place where gravity pulls everything in, even light. Just like every brushstroke plays a part in creating a beautiful painting, supernovae and black holes are essential elements in the magnificent tapestry of our universe.
The scientific study of the universe is known as astronomy. Astronomers observe and analyze celestial objects such as stars, planets, galaxies, and phenomena like supernovae and black holes to better understand the nature of the cosmos.
No, the Sun is not the hottest place in the universe. There are other extreme environments like the cores of massive stars, supernovae, and regions around black holes where temperatures can be much hotter than the surface of the Sun.
The study of the universe is called astronomy. Astronomy focuses on celestial objects such as stars, planets, galaxies, and phenomena like supernovae, black holes, and cosmic radiation. Geology, oceanography, and meteorology are different fields that focus on the Earth and its atmosphere, oceans, and geological processes.
Some of the most intense sources of light in the universe are quasars, which are extremely bright and energetic regions around supermassive black holes at the centers of galaxies, and gamma-ray bursts, which are short bursts of high-energy gamma rays released during cataclysmic events like supernovae or neutron star mergers.
Large stars ending their life can undergo a supernova explosion, where the outer layers are ejected into space and the core collapses to form a neutron star or black hole. This explosive event releases a huge amount of energy, making supernovae some of the brightest events in the universe.
Black holes do not create supernovae. Black holes are created from a supernovae.
"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
I don't see the relationship.

Red Giants and black holes
Please clarify what your question is.
Dark matter and black holes are both mysterious components of the universe, but they are not directly related. Dark matter is an invisible substance that makes up a large portion of the universe's mass, while black holes are extremely dense regions in space where gravity is so strong that not even light can escape. While dark matter may influence the formation and behavior of black holes, they are fundamentally different phenomena in the cosmos.
There are two explanations. First, when a massive star forms a black hole, usually only a small portion of the star's mass actually goes into the black hole. Most of the rest is blasted away in a supernova, enriching the surrounding space with heavier elements. Second, there are also pair-instability supernovae. Such supernovae occur in extremely massive stars with a very low content of heavier elements, which likely existed in the early universe. Pair-instability supernovae will blow away the entire star, leaving behind no black hole or neutron star remnant.
The universe is not black. The universe as a whole is microwave, at a cavity radiation temperature of about 3 K. The space between stars just looks black because you can't see microwave.

The relationship between the mass of a black hole and its density is that as the mass of a black hole increases, its density also increases. This means that a black hole with a higher mass will have a higher density compared to a black hole with a lower mass.
