Despite some recent studies that indicate the speed of light may have been slowing down, NASA has announced results of examination of light from two nearby galaxies showing that the speed of light is as special relativity describes it.

Specifically, they looked at Mkn 421 and Mkn 501, both of which have massive black holes spewing gamma radiation. The gamma photons collide with infrared photons and annihilate each other. If the speed of light were not constant, the photons from the galaxies would not have enough energy to cancel out the infrared ones.

There has been some investigation into whether or not the quantum foam would impeded the speed of light. It also brings into question some models of a theory of everything involving extra dimensions. The results indicate that the energy levels of these dimensions can't be as powerful as some of the models claim them to be.

Additional observations which support these conclusions can be found in this article:

These observations are also interesting because they support the idea of continuous space-time as opposed to discrete, quantized space-time. The information is useful in combatting apologetics which claim traversal of an infinite set of temporal moments is impossible, i.e. therefore there must be a First Cause. Not that the contrary can't already be demonstrated using convergent series, but it helps to show that the continuum appears to exist in reality.
