Energy and mass are interchangable, photons are affected by gravity thus are gravitationally interacting particles, and if you put enough energy in the form of photons inside a sufficiently small area, the energy density can be equivalent to the mass density required to create a black hole. These &quot;artificial&quot; (because no one has a good explanation how these could ever happen naturally) black holes even have a cool nickname, you call a black hole created…</p><p><a href="https://hackerpaper.kaipfister.de/p/2309.04191/">Paper and discussion history</a>.
