Mike: "my personal opinion is that our Universe may not be expanding consistantly in every direction"
Me: "The Cosmic Microwave Background Radiation has been observed to be isotropic"
Mike: "Forgive me but I was'nt refering to the Cosmic Microwave Background, but to the Universes Constant Expansion."
- CMBR isotropy implies that space is expanding at the same rate everywhere. If it were not, one would expect to find a related anistropy, but such differences in temperature have proven non-existant. The rate of expansion has been shown to be uniform in space, and accelerating in time.
Mike: "which is further strengthened by the assumption that Dark Matter, thats causing our expansion is in (constant?} production, everywhere?"
- I think you mean Dark Energy. If so, can you point me to some info regarding its constant production, as this is news to me.
Mike: "'Tired' light that is coming out from an 'above average' higher gravitational Galaxy than normal..."
- Modern day tired light proponents not only fail to take account of all the evidence, but also apply faulty reasoning. Here's one example:
"Regardless of your beliefs as to how the Universe started, one piece of experimental observation has to be explained - that is, in redshift, the photons of light have a longer wavelength on arrival at the Earth, than when they set off from the distant galaxy. This means that photons of light have less energy on arrival than when they set off.
Where did this energy go?"
- which fails to note that since the energy is stretched in space, it is also stretched in time, i.e., it takes a little longer for the same amount of energy to arrive. No energy if lost.
The tired light theory is defunct,
