Well an amiga is a closed system, so its more reliable. Hell a c64 is very reliable, but not power enough to do anything.
As far as the speed of light is concerned, after having to take a whole year of physical chemistry in college I have to say alot of the theories are made by scientists smoking crack. Every 100 years or so they redo them after somebody gets a real cool idea.. then they spend 99 years doing lab tests to expand or disprove them.
And from my understanding from tests recently done either the 2nd law of thermodymanics or the speed of light is in error, and since we like the 2nd law too much they decided it must be the speed of light that changes.. must have flipped a coin.
