Black holes aren't "infinitely dense" because that is ridiculous
You're misinterpreting the meaning of "infinite" here.
You're assuming density measurement has an infinite value. Like "How many dollars are there?" Well, you could have any number of dollars from 1 to infinity.
That's not how density is measured.
Another type of measurement is "What angle is the corner of that triangle?"
That could be anywhere from 1 to 359 degrees (rounding to whole numbers)
It's kind of like a percentage.
Infinite density would be like saying the angle is 360 Degrees. That breaks the triangle. The angle is effectively infinite.
Mass, density, momentum, time, etc... are all treated like geometry when you get into relativistic effects.
You can't exceed the speed of light because that to would break the geometry of the system. Once you hit the speed of light, you again are doing the equivalent of making one of the angles 360 degrees.
The "Triangle" of this system is Speed, time and mass. So for speed to exceed the speed of light and therefor be the "360 degree angle" of this triangle, the other two angles... time and mass, must be 0. Therefor time stops, and the moving object must be massless. Does that make more sense?
At least thats how I've always understood it.
