Can you compress anything into a black hole?

A black hole is a region of space within which the force of gravity is so strong that nothing, not even light, can escape. In theory, any mass can be compressed sufficiently to form a black hole. The only requirement is that its physical size is less than the Schwarzschild radius.

How small would you have to compress a human to make a black hole?

Smaller masses have correspondingly smaller horizons: for Earth to become a black hole, it would have to be compressed to a radius of only 1 centimeter—less than the size of a grape. A typical asteroid, if crushed to a small enough size to be a black hole, would have the dimensions of an atomic nucleus.

What is the smallest mass possible for a black hole?

NASA scientists have identified the lightest black hole yet, just 3.8 times the mass of the sun, in a binary star system in the Milky Way known as XTE J1650-500. The next smallest black hole, spotted in 1994, weighed in at 6.3 solar masses.

How is light pulled into black holes if it has no mass?

Even though photons have no mass, they are still affected by gravity. That’s how we can see black holes – by the way they distort the light going near them. The reason nothing can escape a black hole is because within the event horizon, space is curved to the point where all directions are actually pointing inside.

Can we compressed the objects easily?

The atoms and molecules in gases are much more spread out than in solids or liquids. Gas can be compressed much more easily than a liquid or solid.

Can a black hole be condensed?

The matter inside a black hole could be condensed down to an indistinguishable blob. Or the matter could retain some structure but remain trapped in the black hole by the black hole’s intense gravity.

Can we compress the objects easily?

The spaces between the molecules in liquids are large, so liquids have very high compressibility. Gases will compress more easily that solids or liquids because there is so much space between the gas molecules.

Is it possible to compress a black hole to Schwarzschild radius?

If you wish to make a black hole from a stellar-sized object, then there is no need to compress it to as small as the Schwarzschild radius (though that would certainly work and would certainly be the answer for smaller objects with negligible self-gravity).

Can anything become a black hole if it is crushed?

Recently I learned that anything could become a black hole (even you) if it were crushed down small enough, for example our sun would have to be crushed to the size of Manhattan to become a black hole (According to a video I saw).

Is it possible to compress gravity to a smaller size?

Instead, you just need to compress it to a size at which it cannot be possibly supported by any plausible equation of state against further gravitational collapse. It turns out that this is somewhat bigger than the Schwarzschild radius and hence the density required is considerably lower.
