Take a rubber band, preferably a long one. Now, take a marker and make three spots on it, one near one end, one in the middle, and one near the other end. the firsts one, in one end, represent the Earth and the others, two galaxies at different distance. Now, take both ends of the rubber band, and slowly stretch it. You will observe that the 'galaxy' at the far end of the rubber band is moving away at always twice the speed of the 'galaxy' in the middle of the rubber band, but they are both moving at constant speed.
Doppler effect is due to relative speed / motion . In this case waves are affected due to the moving objects
BUT galaxies are in fact not moving due to the expanding Universe..
BUT space between the galaxies is expanding.
Expanding space is not the same as motion..
You cannot equalize these two phenomena's.
Not with your hand on the bible, and also not with your hand on the (holy) science book.
So soon you in details tries to explain what time exactly the photon is effected by Doppler Effect,- due to the expanding Universe, that “model” you have in mind will collapse completely.
If you don't believe- try it
Try to explain me, when exactly and how much is a photon z10 (partly or fully) affected:
- A-In the moment it is leaving a star
- B-While it is traveling in space
- C-When hitting the Earth // the spetrometer
If you answer; all, tell me how many percent of the effect is due to A, B, C ?
And answer me also; - how much would these proportional be with a z5 photon.
Hans – this is ill-considered nonsense.
It depend how you difine "gravity"You say that a ball-shaped object is best at 'creating gravity' and that different shapes with the same mass create less gravity.
Yes it creates less ADG because the effect on space is spread out, - cow logic simple.
RightYou say that your gravity model can explain 'dark matter'.
Right, I guess so., This is not important, - if it does have a ball shape, - ADG would be stronger compared to if it is is flat..A galaxy is a flat disk with very low density (only slightly above a vacuum), so it should not be able to create much gravity, compared to its mass.
You have misunderstood that point.Yet, what we observe is that its rotational speed indicates a greater mass than explained by the observable matter.
I said fast moving matter towards the center of the Universe will reach HUGE speed ,- and hence HUGE gravity due to that HUGE speed.
I am not sure whether matter (plasma) in a BigChrunch really (at a certain time) will orbit the central area, - this can be calculted later - this too is not important / decisive for the theory.
The speed and the self-perpetuating-gravity-creating-process due to fast motion of matter towards the center of the Universe and hence the huge speed / mass increase that will cause is enough - to get excactly the effect this theory need >> stronger gravity = ´stronger absorbed space >> BAAAANGGG, - because space cannot continue to contract, - but only to that point when the strong force outplays itself = and hence BAAAAANNNNGGGG
(I guess you have understood gravity and the strong force is a unity, exactly like the old man (Albert) believed....)..
(And I guess you also understand too that there is a limit for how much the strong force can allow space to be contracted / absorbed by matter and hence also that the end of that path is BAAAAAANNNNGG)
