Dividing by zero isn’t a mystery; it’s undefined. It’s because division is the inverse of multiplication. For example, 6/3=? Is the same thing as 3*?=6. In this case, the missing number is 2. If we say 1/0=?, then that’s the same as 0*?=1. In this case, the missing number doesn’t exist. The really interesting one is 0/0. If we say 0/0=?, then that’s the same as 0*?=0. This time the solution exists, but ALL numbers work. That’s why 0/0=indeterminate and any other number/0=undefined.

@CapnVulmorg, I once read a book called Zero about the origins of the number and some math bjtch said since as the value gets smaller the number gets bigger (1/21/41/8), that 1/infinity actually as a value of zero. Meaning that if 1/inf=0, then 0*inf=1 This then opened up a can of worms that an object with no width and infinite length would have an area of 1, but no navigable space. If applied to space stuff, there could be billions of alternate universes that DO exist but we are unable to ever navigate because of their dimensions (that’s not in the book but almost seems reasonable). Crazy stuff

@CapnVulmorg, so I may be going off of an oversimplified way of thinking of division here, and don't have a mathematical degree or anything, but wouldn't defining something by zero just make the result zero? Like you have 8 cookies and you divide them into 0 groups. In examples such as this you typically respond with the amount of cookies in each group, not the number of cookies you had before splitting them up.

@CapnVulmorg, that's why I said technically, I just like the fact that as the denominator approaches 0, the answer approaches infinity (although never reaching it). I have an engineering background and don't know a lot about number theory. I know what I was saying is like saying if a car goes over a speed bump quick enough, then both sets of tyres will hit the speed bump at the same time. I just thought it was nice to think about. I got a lot of unexpected downvotes for that comment, I know you didn't and I found your comment interesting, but I'm surprised so many people took this to heart

@The Next Guy, you might want to stay away from “technically” and stick with “approximately” like the other engineers, lol. I’m a cardcarrying mathematician, and technically is what we do the best. It’s not even true that 1/x goes to infinity as x goes to 0. If x is negative, then 1/x approaches negative infinity. That limit doesn’t exist.

All very easy questions, all very easy to answer. After all, I'm really smart. Interior of a black hole is solid mass, under highly extreme pressure, from very, very high gravity. Anything divived by zero is infinity, because there is no limit to how many times you can add zero to a number without reaching/surpassing it, unless, of course, you divide zero by zero, then the answer is one. How a construction crane gets there is simply piece by piece transported by truck, and then constructed on location, and I've built a quite a few tall buildings, and I've seen them go up so I know what I'm talking about. Dark matter is simply the name we give to forces we don't understand, just like the aether was what we thought the medium was that light needed to travel through space, until they tried to measure it and realized it didn't exist, and once they figured it out they began to study light differently, and now we understand light very well, and we'll figure out dark matter very soon.
Google says cranes can fly, so mystery solved.
