The Surprising Theory: Dark Matter Could be Made of Singularities

⚫️Naked singularities are singularities without a horizon like black holes have.

🌌Naked singularities could offer a plain view of regions with strong quantum gravitational effects.

🌟Primordial black holes are formed from the collapse of stars, while primordial naked singularities could have formed in the early universe.

🔭Observational evidence suggests that primordial black holes do not account for the total mass of dark matter.

🤔The formation of a large number of primordial naked singularities would require a comprehensive explanation for the conditions in the early universe.

What are naked singularities?

—Naked singularities are singularities without a horizon, unlike black holes which have a boundary from within which light cannot escape.

How do naked singularities differ from black holes?

—In addition to not having a horizon, naked singularities offer a plain view of the singularity, while black holes hide their singularity.

What are primordial black holes?

—Primordial black holes are black holes that are thought to have formed in the early universe, either from the collapse of matter or the accumulation of matter onto existing black holes.

Is dark matter primarily composed of primordial black holes?

—It is unlikely that dark matter is primarily composed of primordial black holes, as observational evidence suggests that the total mass of dark matter exceeds what could be accounted for by black holes.

What challenges exist in the formation of a large number of primordial naked singularities?

—A comprehensive explanation would be required to explain the conditions in the early universe that would lead to the formation of a large number of primordial naked singularities without a significant number of primordial black holes.

00:00A team of researchers propose that the universe might be filled with singularities, known as naked singularities, which could make up what we call dark matter.

00:14Naked singularities are singularities without a horizon, unlike black holes which have a boundary from within which light cannot escape.

01:44Primordial black holes are black holes that are thought to have formed in the early universe, either from the collapse of matter or the accumulation of matter onto existing black holes.

02:32Observational evidence suggests that it is unlikely for dark matter to be primarily composed of primordial black holes.
