i think i learned how to collapse the universe and create a new big bang
first, make a square out of solid walls
then, fill the square with a bunch of hydrogen gas
then, make a pile of uranium
after that, make your cursor huge, and increase the air pressure inside of the square
keep going until the hydrogen erupts, and then get ready.
you'll see the uranium start to disappear, keep adding more uranium until all of the bright purple lights are gone
stop adding uranium, look around, there will be singularity blobs eating all the uranium.
let the singularity collapse in on itself, should take a few seconds.
after a few more seconds, small bright explosions of photons should appear.
i cannot explain why this happens
