Debate:If the universe is young and it takes light millions of years to reach us from far off stars, how can we see them? (view source)
Revision as of 18:31, March 17, 2007
, 18:31, March 17, 2007→Theory 3: If C is not constant, then our meters are going to shrink!
C is not actually constant. All measurements on Earth indicate that it is, but beyond our Solar System it could easily be faster, slower, moving through wormholes to appear faster, etc. Hubble's Law says that the farther away a galaxy is, the faster it moves away due to universal expansion, so why couldn't light be similarly expanded with distance? So many of our assumptions about the universe rely on our belief that things happen the same way everywhere - a huge leap of faith for a scientist. --[[User:Daniel B. Douglas|Daniel B.

:I don't know whether you knew, but the official definition of the [[meter]] now assumes that C is constant. The meter is defined in terms of C! Someone needs to set up some periodic re-measurements of the orange-red line from the spectrum of [[krypton]]-86 that provided the most recent definition of the meter: 1,650,763.73 wavelengths of this radiation. If that number starts to rise, then we know that C is slowing, as [[Barry Setterfield]] has stated.
:I have another variation on this theory, however: what if C were originally much faster, is now the speed at which we now find it, and is not going to change anymore? Except that I have an [[Occam's razor]] problem with that.--[[User:TerryH|TerryH]] 14:31, 17 March 2007 (EDT)
