http://en.wikipedia.org/wiki/Special_relativity contains a major error, namely, the claim that the second postulate "has been verified experimentally."

Not only is this not so, but the postulate has not even been experimentally tested.

The status of the second postulate is vital because it is the sole basis of special relativity. This postulate calls for invariance and isotropy in the case of light's one-way speed between two clocks that are in the same frame. (The round-trip light speed case was essentially closed prior to special relativity by the 1887 Michelson-Morley experiment, but the one-way case remains open, contrary to the Wiki Special_relativity article.)

(The first postulate does not call for any specific experimental results, but merely says that whatever results are found in one inertial frame must also be found in all other such frames; thus, the second postulate does not dictate an invariant one-way light speed of c over c � v or vice versa, so the first postulate does not support special relativity.)

This very serious problem needs to be quickly cleared up because of the current polling process which is looking to give the Wiki special relativity article "featured article" status.

The only way that the above-mentioned claim can be made legit is by having its author(s) provide the reference(s) for the alleged one-way light speed experiment(s).

Thank you for your attention,
