AI Thread Summary
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 Summary
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 'Question about Parallel Transport'

In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...

Thread 'Trying to calculate proper time of worldlines using rotating frames'

So, to calculate a proper time of a worldline in SR using an inertial frame is quite easy. But I struggled a bit using a "rotating frame metric" and now I'm not sure whether I'll do it right. Couls someone point me in the right direction? "What have you tried?" Well, trying to help truly absolute layppl with some variation of a "Circular Twin Paradox" not using an inertial frame of reference for whatevere reason. I thought it would be a bit of a challenge so I made a derivation or...

Thread 'Describing the Big Bang'

I started reading a National Geographic article related to the Big Bang. It starts these statements: Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had a beginning, a subatomic point called a singularity. This point of intense heat and density rapidly ballooned outward. My first reaction was that this is a layman's approximation to...
