I need help on how to make a blackhole

I seen a lot of blackhole stuff or something similar on Roblox games but I’m not entirely sure how to make them. I’m not too familiar with Roblox physics so I need some direction on how to make it.

How realistic do you want this to be?

Should you be able to orbit the black hole if you’re velocity is right?

Should the black hole be pulled towards other massive objects?

Or are you just asking how to suck a bunch of parts towards a single point for like a visual effect for a magic spell or something?

I was thinking more as getting pulled by a blackhole which you can try to break free if you struggle and move away from it.
