Keep thinking and expressing, David.

We don’t always have to agree, but your thinking, and expressing said thinking, matters.

Subject: [NatureNS] Expand Universe or Tired Light

Hi Patrick & All,

     Thanks Patrick for the detailed explanation of the Big Bang. In 
bare outline the Hubble Constant, amount of red shift is proportional to 
distance between source and observer, and this is taken as proof that 
the universe is expanding. But is an expanding universe the only way to 
account for these observations ?

    Experience with the properties of light from nearby sources has led 
to the assumption that light, an electromagnetic wave, can travel 
billions of years through magnetic fields, or electric fields without 
modification or loss of energy.  But how can one be sure that light can 
travel for billions of years without some consumption or loss of 
photon/wave energy ?

     The objection that no attrition of photon energy over time, 
regardless of medium properties or travel time, is know to occur is not 
valid because the Hubble effect might be due to such attrition and not 
an expanding universe.

      And, with math proficiency degraded by moth, time and rust to 
about grade 8 level I am not in any position to debate this subject. 
Just express doubts about interpretation.

     But falling back on an old saying, as a Parthian shot; "Discovery 
is seeing what everyone else has seen and thinking what no one else has 
thought."

Yt, DW, Kentville
