- Purpose of use
- Determining the speed of the 1991 "Oh My God" particle event based on an assumption of it being a slightly less fast iron nucleus, and then applying that speed to a 4mg micrometeor (diameter of ~ 0.5mm) and calculating if the energy would be less or more than the energy of the Chicxulub impact event. 2,200,729,956,560,423,000 MJ seems to be roughly equivalent to 4 dinosaur-killing asteroid impacts at the same time.

- Purpose of use
- understanding why exceeding the speed of light would violate half of the known physics

- Purpose of use
- What would be the surface gravity of a DVD of the film 'Gravity' starting Sandra Bullock if it was accelerated to 99.99999999999702% the speed of light? The answer is a rather poultry 0.0000043g. This low number probably reflects the poor quality of the film.

- Purpose of use
- Had a silly little idea I rattling around in my head for years. Thought I could prove it wrong and put it to bed. Turns out it''s valid to more than 16 decimal points. Now I have to kind a competent physicist and ask him how WTF??? Thanks so much, if I had found this site earlier I would be finished now. ;-)
