As I understand it, the Doppler shift measurement is a plus for a redshift and a minus for a blueshift. A plus will constitute a reduced frequency and a minus will constitute an increased frequency.A frequency is ascertained via a time integral,I have explained previously that this is not true ie: waves per 'second'. The time integral used is the 'standard second' that also contains within its structure, the constants of the speed of light,no it doesn't and the distance of 299 792 458 meters.not true either
By dividing the constants of the mathematical structure of the means of ascertaining frequency as though it were the time, distance, velocity formula, using the constant of 299 792 458 meters as d, the speed of light c standing in for t, and the measure of the frequency, (being the only variable), instead of v:d/fc=t~ whereby t~ will be a longer second than our standard second.
Yes, you 'could' say that the caesium atom blue shifts when moving into a weaker gravitational field, and that every particle with mass will do so.
A photon does the opposite, it red-shifts into a weaker gravitational field.
The standard second is what we use to measure everything in physics. It is used to measure the speed of light
The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its precise value is 299792458 metres per second (approximately 3.00×108 m/s), since the length of the metre is defined from this constant and the international standard for time.
If you think for one minute that the 30 or so theoretical physics books that I have read over the last 8 years haven't covered all of that then you haven't read many theoretical physics books.
I am looking at the possibility that because the photon has no mass that this reduction in frequency in a weaker gravitational field can be indicative of an additional phenomenon of an inverted time dilation, whereby the extra length in wavelength of shifted light is 'inverted time dilation' related, ie: it takes the light a longer 'time' to cover same distance, and the extra length of wavelength is then not an extra length in actual distance.

QuoteA photon does the opposite, it red-shifts into a weaker gravitational field. And there's the source of your confusion.[/qoute]I have no confusion.Quote from: alancalverd on 21/05/2016 19:45:10Time slows down in a stronger gravitational field. Therefore a photon travelling towards a stronger field will appear to the observer to be blue-shifted, and a photon travelling towards a weaker field will appear to an observer in the weaker field to be red-shfted.Why is your light clock's frequency's direction of increase and decrease in a gravitational field the opposite of your caesium clocks direction of frequency when exposed to changes in the gravitational field?Quote The standard second is what we use to measure everything in physics. It is used to measure the speed of light both irrelvant and untrue! Back to Wikipedia:Quote The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its precise value is 299792458 metres per second (approximately 3.00×108 m/s), since the length of the metre is defined from this constant and the international standard for time. What can I say? I repeat, anything that measures per second, holds a second constant. I can see the possibility of using other constants related to a second, ie: the speed of light, and via the speed of light, 299 792 458 meters of distance, as a substructure in relation to frequency, joules, ev, when calculating gravity and light. I'm sorry you can't see it.QuoteIf you think for one minute that the 30 or so theoretical physics books that I have read over the last 8 years haven't covered all of that then you haven't read many theoretical physics books. But why haven't you learned the most basic aspects of relativity from them?
Time slows down in a stronger gravitational field. Therefore a photon travelling towards a stronger field will appear to the observer to be blue-shifted, and a photon travelling towards a weaker field will appear to an observer in the weaker field to be red-shfted.
I am looking at gravity from the point of view that everything is 'slowly' pulling together from a uniform 'sea' of particles, until all that is left is black holes that eventually merge into each other until there is only one left with everything of the universe in it.This singular black hole, with no equivalent gravitational force acting upon it, ejects the matter of the entire universe (Big Bang) via its accretion disks (inflation period) until it's extinction, leaving a uniform sea of particles that start clumping together. Distances of space between clumps of mass are created by particles vacating their former positions as mass is pulled together, but the actual spatial dimensions of the universe itself are slowly contracting as mass further clumps.
I was just beginning to wonder where you were, and here you are!
And here we can see that I am not the only mind in the world considering that the universe is not expanding:http://www.sci-news.com/astronomy/science-universe-not-expanding-01940.htmlQuote:""Therefore if the Universe is not expanding, the redshift of light with increasing distance must be caused by some other phenomena – something that happens to the light itself as it travels through space.“We are not speculating now as to what could cause the redshift of light,” Mr Lerner said.""Unquote:
