Speed of Light

Just how fast is the speed of light? Los Angeles to Mumbai is 8713 miles. An aircraft flying as the crow flies (a route which passes over the north pole) would require 15 hours 50 minutes to traverse this distance.
A light beam travelling in vacuum would require 46.8 milliseconds! That’s how fast light is!

On a side note, why do aircraft take the 22 hour European route to India when they could take the 16 hour trans-polar route? Answer, because of several reasons – 1)lack of places to land in an emergency, 2) exposure to increased radiation because the earth’s magnetosphere is thinnest over the poles, 3)increased magnetic and solar activity at poles can throw off navigation and communication systems.
