"Foamy Bumps"
« on: 16:06:51, 23 February, 2010 »
I have a question related to an article in a recent issue of ASTRONOMY Magazine: "Fermi Space Telescope
boasts big haul".

It is speculated that the higher energy (E=hù) photon, at its very high frequency may be
interacting with "space-time foaminess", thus slowing it. The article then concludes that
"the more energetic photon did NOT slow over 7 billion light years"; yet also states that
the higher energy photon arrived "less than 1 sec" after the low(er) energy photon. So it
appears that it DID slow, did it not? 
Where is my misconception?
I'd appreciate to learn where I am going wrong in my concept(s). >:(
