Do singularities exist in nature?

Naked singularities have not been observed in nature. Astronomical observations of black holes indicate that their rate of rotation falls below the threshold to produce a naked singularity (spin parameter 1). GRS 1915+105 comes closest to the limit, with a spin parameter of 0.82-1.00.

Is it possible our universe is in a black hole?

The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.

Is singularity proven?

Singularities are predicted to exist in black holes by Einstein’s theory of general relativity, which is a theory that has done remarkably well at matching experimental results. The problem is that infinities never exist in the real world.

What is inside a singularity?

In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.

How is a singularity possible?

General relativity predicts that any object collapsing beyond a certain point (for stars this is the Schwarzschild radius) would form a black hole, inside which a singularity (covered by an event horizon) would be formed. The termination of such a geodesic is considered to be the singularity.

Can we create a singularity?

Scientists in principle could create such singularities by compressing very light particles such as neutrinos sufficiently quickly. One would want to arrange neutrino emitters spherically, aim them at one central point and ramp up their beam intensity rapidly.

What would the Singularity look like?

What would a singularity look like in the quantum mechanical context? Most likely, it would appear as an extreme concentration of a huge mass (more than a few solar masses for astrophysical black holes) within a tiny volume. Now imagine two such singularities colliding as a result of the merger of two black holes.

What would a singularity look like?

When a naked singularity is objectlike, it looks rather like a black hole unclothed by a horizon (hence the name). If you point a camera straight a black hole, you will see only inky blackness. If you point one at a naked singularity, you will see a small but bright object, albeit one with an unusual spectrum of light.
