So it turns out the speed of light might not be constant after all Comments

So, it seems the speed of light isn't quite constant after all. Two new studies published in the European Physical Journal D suggests that the speed of light in space isn't quite constant after all. The understanding is that space is not quite the perfect vacuum which it is often assumed to be. Continue Reading

    Physics is based on approximation at a very small scale to accurately predict phenomena upto very large extent after which the effect will not be significant enough to be noticed. speed of light is constant in absolute vacuum which our space is very very very very near to. Therefore this is not a very strong argument against physics.

    PAUL W STAMP: "The headline of this article is intentionally misleading. "

    Author Marshall Connolly's calling card on Catholic On-Line seems to be writing provocative, psuedo-scientific titles for articles that contain misleading or no facts, and seldom, if ever, present any credible science to support the taunting headline. To his credit, however, his articles do seem to generate many comments here, including from me, so apparently someone being consistently misleading or wrong can make an entertaining read. If it brings more people to peruse some of the more serious Catholic On-line articles, then I'm all for him continuing with his current, albeit flabbergasting, MO.

    This article tells us nothing that hasn't been common knowledge for at least 100 years. The author should be embarrassed and either remove the article or completely rewrite it so it actually reflects new findings of the study.

    More absolute proof that god exist. At this point only the mentally weak could ever ignore the evidence of God's Holy Light in our world!

    It is already well understood and universally published that light travels slower through a medium than through a perfect vacuum. The textbooks are not lacking. This is not news.

    This article seems to be more about an observation of the behavior of light in space than an observation of the behavior of light.

    The headline of this article is intentionally misleading. The speed of light IS constant in a perfect vacuum. The real nature of this article is that space isn't a perfect vacuum--but this changes nothing regarding the constant c. It would be more accurate to state in the headline that space is not a perfect vacuum, and that the speed of light traveling through space may not be constant. Big difference.

    This should be titled, "Space may not be a vacuum." The speed of light, which is essential for the theory of relativity, changes in different mediums. People know that. That space may not be a perfect vacuum, or how vacuous it is does not mean that the speed of light is not constant, which I will still assume that it is.

    Please revise your title to "So it turns out the speed of light, in space, might not be constant after all"

    The speed of light is still constant in a vacuum.
