I almost already know this is going to be rejected but I have to submit this. I have liked all the new things tpt has added into the game. And I thought a space-time mode would be very cool. Basicly It is either a mode or a new set of elements I am not sure which but It would go like this. The new black hole wouldn't be a part in the simulation actually quite the opisite. It would be a hole. A negative part in the simulation. Much like how particles are another part. Walls are not a part but black hole would be negative so when made it would create a much stronger pull than done now. It would suck in all particles including anar. And because when it is said light cannot escape a black hole. It does not always mean they get sucked in. Rather they orbit around the black hole. Another thing that would add to the cool affect of black holes is that when something is sucked up the closer it gets the more it would start to look like persistent display. I just thought this would be cool to make.
I know but all these things are still seperated if all of them could come together that would make a great combo
Perhaps photons falling towards the black hole can be blueshifted, while those travelling away from the black hole could be redshifted?
