Is it possible to create a black hole?

Is it possible to create a black hole?

To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. In such scenarios, black hole production could possibly be an important and observable effect at the Large Hadron Collider (LHC).

Have we solved the black hole information paradox?

No, Stephen Hawking’s Black Hole Information Paradox Hasn’t Been Solved. But outside the event horizon, the black hole is predicted to emit radiation. Hawking’s 1974 work was the first to demonstrate this, but that work has also led to a paradox that has not yet been resolved.

What is the most accepted theory for the origin and evolution of the universe?

Throughout history, countless myths and scientific theories have tried to explain the universe’s origins. The most widely accepted explanation is the big bang theory. Learn about the explosion that started it all and how the universe grew from the size of an atom to encompass everything in existence today.

Is Hawking radiation proven?

Hawking radiation has never been observed, but if it exists the information lost when objects enter a black hole might be carried out of the black hole via this light. Thus the information isn’t truly lost.

Is there such a thing as negative mass?

Astrophysicists have always thought negative mass requires exotic physics that would be impossible in our cosmos. They were wrong. Negative mass is the hypothetical idea that matter can exist with mass of the opposite sign to the ordinary stuff. Instead of 2 kg, a lump of negative mass would be -2 kg.

Does the equivalence principle apply to negative mass?

In most analyses of negative mass, it is assumed that the equivalence principle and conservation of momentum continue to apply, and therefore all three forms of mass are still the same, leading to the study of “negative mass”. But the equivalence principle is simply an observational fact, and is not necessarily valid.

Does negative mass violate the laws of the universe?

In particular, physicists have investigated whether negative mass would violate various laws of the universe, such as the conservation of energy or momentum and therefore cannot exist. These analyses suggest that although the interaction of positive and negative mass produces counterintuitive behaviour, it does not violate these conservation laws.

Can negative mass produce a reasonable Schwarzschild solution?

The crucial breakthrough by Mbarek and Paranjape is to show that negative mass can produce a reasonable Schwarzschild solution without violating the energy condition. Their approach is to think of negative mass not as a solid object, but as a perfect fluid, an otherwise common approach in relativity.
