Can black holes be made from light?

German for “ball lightning,” a kugelblitz is a black hole made from light rather than matter. Since gravity treats mass and energy the same, in theory, we can focus enough radiation into a tiny space and produce an event horizon, an area in space so densely packed (with either matter or energy) that nothing can escape.

Does a black hole absorb 100\% of light?

A black hole is known to absorb all sorts of every (light, radiation..). If it absorbs -all- energy around it, it should in addition emit all energy it has absorbed. But due to its vast gravity noting can “escape”, and therefore nothing is actually emitted.

Can you 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).

Does black hole reflect light?

In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass.

Is a Kugelblitz possible?

It is not possible with current technology. There might be other things getting in the way too, making it totally impossible. Very high energy radiation is prone to react with other radiation.

Can we generate Kugelblitz?

We cannot generate one. The laser needed to generate one a kugelblitz would have to be about a billion times stronger than current gamma ray lasers, also would need frequencies orders of magnitude higher than currently possible.

Can black holes absorb dark matter?

Besides, a small amount of dark matter probably already falls into black holes. Dark matter doesn’t interact electromagnetically – so cannot emit, absorb or scatter light – but it does respond to the force of gravity, so would fall into a black hole in the same way that ordinary matter does.
