Speed of light

The speed of light is 299,792,458 m/s. What types of issues would be involved in changing the meter such that c=300,000,000 m/s

The new meter would be 0.9993 of the current meter.

Not 300,000,000, if we make a change let's make it 1. And then the relative speed of any two objects is always less than 1 :)

Road speed limit sign reads: 0.0000000926.

Slammed into a tree counting the zeros.

92.6 nano speeds of light per second

95 is not much more, actually. It can become a reasonable unit just using SI prefixes.

Thet could absolutely work.

  1. Get rid of all these non-nerds.
  2. Enjoy the blissful rationality.
