Is VSL the Key to Interstellar Communication and the Fate of Humanity?

GLAST to test VSL?

At least two astronomers think it will be possible before 2010, to observe 'the frequency-dependent propagation of high-energy photons from GRBs' (strictly speaking, they feel that GLAST observations may be able to test quantum gravity, but the data may also show VSL). The link:

A big thanks to Jeebus for his pointer to this

Earlier work, using EGRET and BATSE on Compton, as well as Earth-based TeV gamma ray observations, have produced a null result.

Redshift and the speed of light

Everything we know about light tells us its speed is constant. Does anyone want to present some ACTUAL EVIDENCE that it is not constant?

Redshift.

Dr. Andrew Strominger of Harvard pointed out that Einstein himself modified relativity in 1915, when he brought gravity into the picture with his general theory of relativity. Special relativity, as the 1905 theory became known, is only strictly valid in flat space without gravity, Dr. Strominger said.

So it's relative?

Yikes, didgging up a dinosaur. No, redshift is not evidence of VSL.

Yes, I understand you could model it that way, but since that model doesn't fit with other observations of the speed of light, you have to directly measure a vsl before you can use it as a model for cosmological redshift.

The theory of VSL dictated that professeur M Majueieojioue would transport his body to another region of the universe and make contact with aliens who would tell him that the human species is doomed to an eternal hell of evil robotic takeovers of the basic biohumanic chain of living that keeps us all alive.
