Point to Ponder

[Gregory Matthews]

Under standard conditions, light travels at a speed of 186,282 miles per second, or 299,795.458 meters per second.

*  It takes 500 seconds (a bit over 8 minutes) for a photon of light to travel from our sun to us.

*  It takes 100,000,000 seconds for a photon of light to travel from the sun to Proxma Centauri.

*  It takes 100 quadrillion (ten to the 17th power) for light to travel from the cosmic horizon to us.

*  Under standard thought, some of the photons hitting our bodies today have been traveling for  some 13,800,000,000 years.

*  The atoms that currently make up our bodies may once have existed in dinosaur eggs, trilobites, deep within stars, and in gas that came from distant space.
