If our solar system is being drawn toward a black hole in the middle of our galaxy and far away other solar systems are collapsing toward the center of their galaxies, then indeed there would be a red shift even if there is no relative movements between the center of the galaxies. Could you explain that one? Wouldn't you also observe the wavelength contracting if they were going toward the black hole from a different frame of observation? Causing the light from the galaxies to change color? But what we observe is only that the wavelength is being pulled in one direction causing only a red-shift so it can ONLY indicate expantion. But if you have some reference where evidence has been found about the 'black hole/red-shift theory' you talked about I'd be really interested in reading about it. All great truths begin as blasphemies I smoke pot. If this bothers anyone, I suggest you look around at the world in which we live and shut your fuckin' mouth.

The Doppler Effect is usually thought of as a source moving and its effect on the wavelength received at a frame of reference that is stationary. Yes. As the light moves toward us the wavelength is moving faster, as it is going away from us, it is going slower. If im not mistaken this process does change the color of the light though. If the galaxies were moving towards us they would not be red-shifting.
But any radial velocity of the stars caused by attraction toward the center of their galaxy (black hole or not) would diminish the effect. On the other hand, stars moving away from us would have the wavelength elongated further by the same radial velocity. I doubt you'll find any evidence for this.
Thus the light from the near side would produce more waves and a more apparent elongated state at our stationary receiver. If the receiver is our planet and is moving toward the center of our galaxy, the effect would be intensified even if the galaxies were stationary. I'd need to see evidence for something like that. I'd figure astrophysicist and cosmologist would have already taken our rate of speed into account. I could be wrong though.
So I simply question the use of Doppler and put forth a hypothesis that the results may be biased. Whats wrong with the Doppler? It's measurable, it makes predictions, it's falsifiable...What don't you like about it? Just because it goes against what you were able to postulate doesn't make IT wrong...I think it makes you wrong. All great truths begin as blasphemies I smoke pot.

Would I be the first that someone thought was wrong? A stellar group of folks I would say. Of course not.
I only suggest that Doppler should be confirmed by some other means before closing the book forever. Sometimes one means is all you'll be able to have. If it as solid as something like the Doppler which can not only be tested for accuracy on galaxies but it can be tested here on Earth with something as simple as a car, I think you've got yourself a pretty good means for testing direction. I do see your point though. But don't forget that the metric space in between the galaxies is also measured and this further indicates that the space between them is expanding.

I would think this little thing called gravity would decrease in strength with the ever expanding universe. Thats the issue basically, that gravity seems to be lossing out to whatever it is thats expanding the Universe. If gravity was effecting the expantion then something like the Big Crunch... Big Crunch - Wikipedia ...would happen. However, the Universe is expanding and accelerating with no indication of regressing, so that is why the predicted outcome is now shifted more to a Big Freeze.

Dark energy isn't used to talk about the expansion of the universe. The problem is that, in the last few years, measurements indicate that the rate of expansion is increasing.

That is exactly why 'Dark Energy' is a hypothesis right now , because of the observation. Huh? All great truths begin as blasphemies I smoke pot. If this bothers anyone, I suggest you look around at the world in which we live and shut your fuckin' mouth.

Wow, you guys are masters of the bleeding obvious.

If galaxies are shrinking then the space between them would be expanding. If galaxies were shrinking, then they would all appear to be moving away from us at the same rate. But we observe that farther objects are moving away from us faster than near objects (some of which are actually getting closer to us) which is consistent with the Big Bang. If galaxies were shrinking then stars in our own galaxy would be blue shifted toward us, which we don't observe. Edited by onifre, : No reason given.

This would be called "blue shift". Thanks, I have since changed it. All great truths begin as blasphemies I smoke pot. If this bothers anyone, I suggest you look around at the world in which we live and shut your fuckin' mouth.
