Re: [Utah-astronomy] Speed of Light speculation
It is to me too, Deloy. Thanks, Joe PS, it seems to me the issue they're talking about isn't really the theoretical speed of light in a vacuum, but the actual speed of light in space, which isn't a true vacuum. If so, the effect is really the changes in speed when light travels through some medium. We already know light slows when it travels through water. But that variability shouldn't affect any fundamental property of matter, contrary to what these scientists' position. ------------------------------ On Sun, Apr 28, 2013 9:37 AM MDT D P Pierce wrote:

In fact, the speed of light slows when traveling through anything other than a vacuum, and not insignificantly. That is what is represented by refractive index. It is the ratio of the speed of light in that medium divided into the speed of light in a vacuum. ________________________________ From: Joe Bauman <josephmbauman@yahoo.com> To: utah-astronomy@mailman.xmission.com Sent: Sunday, April 28, 2013 11:43 AM Subject: Re: [Utah-astronomy] Speed of Light speculation It is to me too, Deloy.

Since when do photons have charge? Second proposal, second paragraph. Dave On [Apr 28], at [Apr 28] 2:15 PM, Brent Watson wrote:

Of course the speed of light is slower in a vacuum. My wife says she can't see me vacuuming at all.
