"Einstein's theory of special relativity says that all electromagnetic
radiation travels through a vacuum at the speed of light. This speed
is predicted to be constant, regardless of the energy of the
radiation. Yet in 2005, the MAGIC gamma-ray telescope on La Palma in
the Canary Islands suggested the speed of light might not be constant
after all. The telescope, which measured the light released by a
galaxy around 500 million light years away, found that higher energy
photons arrived four minutes behind their lower energy counterparts.
(...) Now new observations suggest quantum gravity cannot be
responsible for the time delay observed by MAGIC. The light from a
powerful, 7-billion year old gamma-ray burst detected by NASA's Fermi
Gamma-ray Space Telescope shows no evidence of a lag between photons
of a range of energies. "We have fewer stomach aches now," says
Amelino-Camelia. "The Fermi data has pushed the limit where it's now
proven the MAGIC data cannot be interpreted in that way."

The MAGIC data cannot be interpreted in that way? That is, "quantum
gravity cannot be responsible for the time delay observed by MAGIC"?
Then what is the only reasonable conclusion? Three possible versions:

BURST OF SUPPORT FOR RELATIVITY

EINSTEIN STILL RULES

EINSTEINIANA IS AN ETERNAL MONEY-SPINNER

NATURE: "Burst of support for relativity. Light from a distant gamma-
ray burst backs up a key prediction of Albert Einstein's theory of
relativity - that photon speed is the same regardless of energy."

1. Observations suggest that high-energy photons travel through space
slower than low-energy photons.

2. Einsteinians (Lee Smolin and brothers in this case) advance
theories predicting that that high-energy photons travel slower than
low-energy photons. Career, money etc.

3. A single observation suggests that high-energy photons travel
through space slower than low-energy photons but the difference in
speed is small.

4. Einsteinians (Lee Smolin and brothers again) discover "a key
prediction of Albert Einstein's theory of relativity - that photon
speed is the same regardless of energy".

5. Einsteinians (Lee Smolin and brothers again) make a second
discovery: the single observation confirms the "key prediction of
Albert Einstein's theory of relativity" and therefore there is "burst
of support for relativity" in the world.

6. The journal Nature immediately publishes Lee Smolin and brothers'
discoveries. Career, money etc. for Nature editors, Lee Smolin,
brothers and sycophants.
