What are the key differences between a magnetar and a black hole?
A magnetar is a type of neutron star with an extremely strong magnetic field, while a black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape. Magnetars are made of dense neutron-rich material, while black holes are formed from the collapse of massive stars.
What are the key differences between a black hole and a black hole, and how do these distinctions impact our understanding of these enigmatic cosmic phenomena?
It seems like there may be a typo in your question. Did you mean to ask about the key differences between a black hole and a star?
What are the key differences between the M87 black hole and Sagittarius A, and how do these differences impact our understanding of black holes in the universe?
The key differences between the M87 black hole and Sagittarius A are their size and activity levels. M87 is much larger and more active, while Sagittarius A is smaller and less active. These differences impact our understanding of black holes by providing insight into the range of sizes and behaviors they can exhibit, helping us to better understand the diversity of black holes in the universe.
What is the relationship between the mass of a black hole and its density?
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.
What is the relationship between black hole entropy, soft hair, and their implications for our understanding of the information paradox?
The relationship between black hole entropy, soft hair, and the information paradox is that they are all interconnected concepts in the study of black holes. Black hole entropy refers to the amount of disorder or information contained within a black hole. Soft hair refers to the low-energy quantum excitations around a black hole that may store information about what falls into the black hole. The information paradox arises from the conflict between the idea that information cannot be lost in a quantum system and the theory that black holes can destroy information. Recent research suggests that soft hair may play a role in resolving this paradox by potentially encoding information about what falls into a black hole, thus preserving it.
What is the difference between a black hole and neutron star?

Can any black hole turn into a neutron star?
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.

What happens when a star is too small to be a black hole but too big to be a neutron star?
There's no mass range that's between "collapses into a neutron star or pulsar" and "collapses into a black hole". It'll be one or the other.

A black hole or a neutron star.
Is a neutron star or a black hole bigger?
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
What remains after supernova?
A neutron star or a pulsar, or a black hole.
What factor determines if a neutron star forms or a black hole forms after a supernova explosion?
The factor that determines whether a neutron star or a black hole forms after a supernova explosion is the mass of the collapsing core of the star. If the core's mass is between about 1.4 and 3 times the mass of the sun, a neutron star is formed. If the core's mass exceeds about 3 solar masses, a black hole is likely to form.
When was a star is dead?
When it turns into a black dwarf neutron star or black hole.
What is bigger a black hole or a neutron star?
It all relates to what you define as big. A black hole is an infinite region in space with an infinite density. It's "event horizon" is not infinite. If you wish to categorise between size of a neutron star and a black hole's "event horizon", then a black hole is, in most cases larger - but there are micro black holes, which exhibit all the characteristics of a black hole but have a much smaller "event horizon". In the physical sense, everything is bigger than a black hole, but in a terminological sense (the event horizon) it would depend on the mass of the black hole.
What is the size of a black hole?
about 1/3 of a neutron star
