Light, Velocity of. It has been proven by astronomers that light travels through space with the prodigious, though finite, velocity of 192,500, or nearly 200,000 miles in a second of time, and consequently would pass round the earth in the eighth part of a second. It is also proved, by the phenomena of aberration, that the light of the sun, planets, and all the fixed stars, travels with the same velocity.
