This is easily the most educating answer i've had for my question, and for that i am very grateful to you.
Ultimately, the core of my question was about the role that initial density alone plays in the process of the formation of a black hole. But i've failed at bringing this fact up clearly...
Sorry if i was unclear about my though experiment. I'll now clarify as precise as i can.
We instantaneously materialize the two spheres in a vacuum. We assume that they do not interact with each other in any way and are infinitely far away from each other.
No, the spheres are in a state of...
The other day, a friend and I had a discussion about black holes, namely how the density of a body affects the process of its transformation into a black hole.
My friend and I have too little collective knowledge in the field of theoretical physics regarding black holes, so the discussion has...
