for 800nm to 400nm, we need gamma=2. So v~.86c. At 20m this gives you ~80ns.

For perspective, this speed is:

  • 928 157 450 kilometers per hour
  • 576 730 301 miles per hour

In one second, you would travel around:

  • 258 000 kilometers
  • 160 000 miles

Which is around 6.43 times around the Earth's equator.

About 3 large boulders the size of a small boulder.

We are all the size of boulders on this blessed day.
