Creating a black hole is theoretically possible according to current physics, but it remains highly unlikely and impractical. Simulating some properties of black holes has already been achieved, but generating an actual black hole would require immense energy and resources. The discussion also touches on the challenges of safely approaching a black hole, particularly regarding its size and the effects of evaporation. The concept of a small, manageable black hole for educational purposes raises questions about feasibility and safety. Overall, while the idea is intriguing, significant scientific and logistical hurdles remain.

TL;DR
Could humans ever create a black hole or get near one?
I feel like that would further people's understanding of physics.

No law of physics prevents it, but it's highly unlikely, and it certainly wouldn't be easy. If by "creating a black hole" you mean reproducing or simulating some of its properties, that's already been done.

The question of whether we'll ever be able to get near to one is a question about long-distance travel, and a bit about black holes (in the sense of what it would be like to be near to one).
 
So you want a handy 1 kg black hole to pass around the classroom ?
It will be smaller than a normal proton, how will you hold it ?
How will you fund the incredible amount of energy needed to create it ?

With a mass that low, you'll have to hand the evaporating "hot potato" around very fast.
 

Thread 'Is using r as a coordinate in Birkhoff's theorem a limitation?'

In Birkhoff’s theorem, doesn’t assuming we can use r (defined as circumference divided by ## 2 \pi ## for any given sphere) as a coordinate across the spacetime implicitly assume that the spheres must always be getting bigger in some specific direction? Is there a version of the proof that doesn’t have this limitation? I’m thinking about if we made a similar move on 2-dimensional manifolds that ought to exhibit infinite order rotational symmetry. A cylinder would clearly fit, but if we...
