Laugh away:
I know how to divide by zero.
I haven't figured out the mathematical/physical ramifications of my discovery all the way, yet, but needless to say I feel a great responsibility to research its effects on reality before publishing my work.
Like I said, laugh away, but I've outpaced Einstein and Steven Hawking by discovering math they couldn't envision and I'm withholding my ideas until I'm ok with understanding what will happen to the public when I expect to release this new, outrageously simple but pretty damn profound teaching that will redefine our view of reality and space/time.
Again, laugh, but be ready to eat crow later.
