Both propose somewhat different mechanisms, but the idea is that the speed of light might change as one alters assumptions about how elementary particles interact with radiation. Both treat space as something that isn&#8217;t empty, but a great big soup of virtual particles that wink in and out of existence in tiny fractions of a second.<\/p><\/blockquote>\n<p>The problem I find with articles like this is that they don&#8217;t place enough emphasis on the speculative nature of the work \u2014 something is being assumed about nature that hasn&#8217;t yet been observed, and the authors are investigating the consequences. From the perspective of science this is fine \u2014 that&#8217;s one way of going about it: think of some novel way nature might be structured, come up with a model, and test it. That&#8217;s valid science. But at this point that last part is missing, and as long as it is, one has to worry about over-selling the idea.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speed of Light May Not Be Constant Two papers, published in the European Physics Journal D in March, attempt to derive the speed of light from the quantum properties of space itself.
