I Know Lots of Useless Information

How "Fast" is the Speed of Light?

Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second.

Really? I don't know what to believe on the internet. 😱

Actually I screwed up, Mia culpa. It is 186K miles per second, I typed too fast, faster than my mind processed it! 😏

@samueltyler2: Things move too fast around here.

It is miles per second. Some of the stars we see the light from are no longer there.
