Who Discovered the Speed of Light

Seth, I stand corrected on who and when the speed of light, as a specific finite speed, was first discovered. Interesting enough Aristotle stated the speed of light was a finite speed. But he didn’t state what that speed was.

Speed of Light Expansion due to reduced vacuum Permittivity
by baxman2＠q.com 01 May '13

01 May '13

James Clerk Maxwell discovered the speed of light in his 19th century research. He expressed it as 1 over the square root of (vacuum permeability time’s vacuum permittivity). These vacuum properties can be reduced in the presence of negative energy. This negative energy is defined in terms of a lack of zero-point-energy vacuum fluctuations. This condition does exist in a space known as a casimir cavity. This means it is possible to expand the speed of light to be faster then c. An article related to this can be found in Marcel Urban, François Couchot, Xavier Sarazin, Arache Djannati-Atai. The quantum vacuum as the origin of the speed of light. The European Physical Journal D, 2013; 67 (3) DOI: 10.1140/epjd/e2013-30578-7

Fw: Atacama - Starry nights
by Joe Bauman 30 Apr '13

A friend emailed this video to me, knowing I'd like it, and suggested that Siegfried would too. After watching it, I'm about ready to move to Chile. Anyway, I think the UtahAstronomy group would get a kick out of this. -- Joe ----- Forwarded Message ----- From: Tom Zebal <tomzebal(a)gmail.com> To: Joe Bauman <josephmbauman(a)yahoo.com>; Chris Cottril <djchrismo(a)gmail.com> Sent: Tuesday, April 30, 2013 7:05 PM Subject: Atacama - Starry nights Joe, Chris - here is one you may want to pass on to Sieg!
