Is there a difference between claud in the vscode extension and Claude code? I mostly use chat mode but will sometimes try agent and neither really make me happy. Id say if a task could be given to a high school programmer the AI agents can do it about 30÷ of the time.

You only need a high enough density of mass to form a black hole. You could take any amount of mass and in theory squeeze it hard enough to produce a black hole.

The sun is not massive enough for the astrophysical processes to form a black hole, but if you squeezed the sun into a small enough space by some magic it you could form them.
