      But when was it conclusive to say yep these exist and we call them black holes and don’t need a theory anymore because they are fact? How come scientists say that a black hole will rip anything that enters apart. But what if treated like a shower drain. Match the speed at the lip of the black hole and slowly go down increasing speed when you get deeper. Like a funnel. Speaking of that what is the speed at which a black hole “disintegrates” stuff?

        You misunderstand what a theory vs a fact is. If a fact is a lego brick,a theory is a what you build.

        A theory collects facts and builds a cohesive narrative to explain why they are. Most importantly there will be gaps, so a theory makes predictions about facts that we don’t have yet. When a new finding fits expectations, then the theory is supported. When a new finding is unexpected or doesn’t fit, it’s time to reclaim the bricks and build a new structure.

        So black holes were predicted and fit the theory very well. It increased our confidence that the theory was moving in the right direction.

        A black hole is a single point. The “funnel” doesn’t go “down” like a drain…it goes inward towards the center of that point from all directions at once.

        That funnel idea is just a graphical representation that they use to illustrate the idea. But, in reality, it doesn’t make sense to represent it that way. The effect is similar, but you have to try and imagine it happening in all directions at the same time…like a spherical funnel…which is difficult to visualise.
