Maybe somthing wrong with Hable constant or redshift is not redshift, but light emision from colder stars? Or maybe redshift is becouse some glaxis or stars rotating near to speed of light and maybe that's becouse is redshift?
Or maybe Universe became not from big bang?
Nearsest galactic quazar is 1.5 bilions light years, then it's means or after big bang this galactic fly with speed of light 1.5 bilions years or that this glactic always flying with about 1/20 speed of light or 5*10^6 m/s. Or that our galactic also flying 2500 km/s.
Maybe galactix are much more nearly than we thinking? And redshift don't exist? Becouse I can't believe, that galactix flying faster than speed of light.
Or maybe universe age is hundeds times older?
from wiki: "Another cause of redshift is the expansion of the universe, which explains the observation that the redshifts of distant galaxies, quasars, and intergalactic gas clouds increase in proportion to their distance from the earth."
Maybe galaxies, which are more far is colder, or maybe light, which going from farthers stars is better absorbed by dust in "blue range" of wavelenght.
"Gravitational redshift is observed if the receiver is located at higher gravitational potential than the source. The cause of gravitational redshift is the time dilation that occurs near massive objects, according to general relativity"
Maybe gravitational redshift occure, when light or electromagnetic waves flying nearly another very massive stars or galactics and they lose they energy, becouse gravitation of galactics taking it and for this reason occuring redshift.
What are you puffing?
