The clean object is still subject to decay in the standard model. Dirt in this case is irrelevant as it will always be removed.

Ok. Let's do this slowly.
The time experienced by the observer is of the essence in the case of the relativistic doppler effect of light. According to the relativistic model the faster you move the slower is your experienced rate of time. We also know that Lorentz contraction dictates that the faster you move the shorter observed distances parallel to the velocity vector become.
Now in fast speeds because of time dilation and Lorentz contraction the observed distances get shorter. This also means that the observed distance that light travels in a year is shorter.
Because observed distances get shorter and also one lightyear is shorter therefore also the wavelength of that light is compressed and thus also the frequency is increased. You agree with all of this?
That is *part* of the effect. In the equations I gave, it is the (1-b^2)^(-1/2) part. There is also the part given by (1+b) for motion towards the source and (1-b) for motion away from the source. This is the dominant effect and corresponds to the decrease or increase in the number of wave fronts passed in any given time interval.

And this part you now talk about you can not give any logical explanation for.

There's also a fallacy in the explanation:
http://en.wikipedia.org/wiki/Relativistic_Dop...
"Since the wavefront moves with velocity c and the observer escapes with velocity v, the time (as measured in the reference frame of the source) between crest arrivals at the observer is t=&#8907;/(c-v)"

That is an absolute fallacy and the whole set of equations is based on the fallacy that the observer can escape the wavefronts. The model dictates that the observer will observe the wavefronts move with velocity c regardless of the observer's velocity. So subtracting v from c in the equations is based on an absolute fallacy.

The equation above is:

The observer is NOT escaping the wavefronts. From the frame of the emitter, the observer is moving through the wavefronts so sees more of them for a given period of time. From the perspective of the observer, there is simply an increased frequency. The subtraction of v from c is NOT due to relative motion of the observer and the light. It is simply counting the number of wavefronts that the observer is moving through in the frame of the emitter. I am sorry that you don't understand that this is the appropriate way to do this, but it is. In the observer's frame, the light goes past at c and there are more (or fewer, depending on the direction) wavefronts that pass.

Given that the model obtains the same result by several different arguments and that the results actually agree with the observations, it seems that *you* are the one mistaken and working from fallacies. Perhaps you should learn how to work in more than one frame of reference at a time and learn what they actually mean.

Knowing is a difficult game in science because nothing can truly be known but only hypothesized about. The contents of the hypotheses are known though :)
From the philosophical perspective I accept that not much can be really known but there are some absolutes that are known by default such as the thoughts that one observes. Fundamentally even all sensory signals are just observed thoughts.
are you saying that we know what we are thinking, and our thoughts about what we think we are observing through various senses, but we are not in touch with some underlying Reality? how would any of those things be absolutes? what do you mean by absolutes that are known by default. give other examples please. how are you defining absolutes? are they the same as Reality? and is Reality ever known, or just some very constant appearances that have never been successfuly contradicted? induction never ends, does it? so a series that proves something could finally be interrupted by something that challenges that proof. we cannot wait to get final proof in many cases. so the preponderance of evidence should be sufficient, not for truth, but for action, if the most cautious action is taken. but what if someone advocates a bold action based on preponderance of evidence? say, regarding man-influenced global warming? or dangers from chemicals, or new drugs?

And that is nonsense. You are now claiming that the observers speed affects the number of wavefronts it will observe during a specific time.

The amount of observed wavefronts is dictated by only these two factors:
- the speed of the wavefronts
- the wavelength

The observer's speed does not affect the number of encountered wavefronts except through time dilation/wavelength contraction. It is an absolute fallacy to subtract the speed of the observer from the speed of the wavefronts. This subtraction is directly from the standard doppler effect.

Subtracting the observer's speed from the speed of the wavefronts has to be done in standard doppler effect but definitely not in the relativistic one.

By subtracting v from c you will have directly violated the constant speed of light law.

For you it must be absolutely certain that you exist if you can observe thoughts. That is one absolute. You observe thoughts and you can not stop observing thoughts while being alive.

Logically it is possible that we are in some kind of simulation and the observed reality is not the absolute reality. However, you see that there is an observable universe and that is another absolute for you. It is absolutely certain that you observe some kind of universe. Whether this universe is the absolute reality or a simulated one becomes irrelevant for you. How ever the universe exists, you can only operate in the reality that you observe (simulated or not). That's another absolute which you can test by putting your hand in fire :) if it is a simulation it's then a pretty good one and you can not escape from it.

For an observer there is no other reality than the one that is observed.

Most of my own actions are made to try and learn the truth about something. For example if I receive some information through hearsay and I would need to act on it, I must then first investigate further without taking any action.

"The absolute quantity of mass in 1kg is 1kg! Period."
That's absolutely hilarious, you're still going on with this stuff.
So how much exactly is 1kg absolutely?:D
What is actually in 1kg of platinum iridium in absolute terms?
1 kg is just an arbitrarily chosen lump, you don't know its absolute content.
Yes, its an arbitrarily chosen lump, just as I pointed out to you some time back. Its a lump with a quantity of mass, and mass itself is an actual quality of the observable universe.
What Cavendish measured was the conversion scaler required for the chose fixed measures. This conversion rate can be transferred into the masses themselves by multiplying all masses with the numerical value given by sqrt(G).
False, what he measured was the actual field strength which can easily be translated into ANY scalar corresponding to any system of measures.
You can easily get rid of G from the model but then you would just need to get used to different values as masses. It's like changing from one monetary system to another. At first it will feel uncomfortable because people are used to certain nice round numbers.
Mathematically the model works exactly the same if you throw away G from the equation and just scale all masses with sqrt(G).
False. Just like real currencies, you can convert from one measure to another but its meaningless unless at some point you show what the money represents. It might be 1 dollar or 20,000 rials that can buy 1 packet of chewing gum, but unless you have a connection to the real world (actual purchasing power), then none of the currency conversions mean anything. G, like the value of a packet of gum, is the LINK between the mathematical abstraction of the equations and actual values that apply to the world. This is why physics is not just pure maths, but maths applied to real quantities with real units.

Now stop babbling about how great your equations are and demonstrate how your equations can deliver the actual mass of the earth. Here is a hint for you: to be MEANINGFUL, the mass has to be in units on a scale that we can directly measure in terms of resistance to force, so the measure cannot be entirely arbitrary. Mass IS inertial mass which IS a real quality of the world, and which we can directly measure only at certain scales.

Stop babbling and prove me wrong.

Yeah if you go 10 mph , you will go 10 miles on 1 hour , if you go 100 mph you will go 100 miles in a hour.

So let me show you how you are so very wrong. By changing your sentence for relativity.

(((You are now claiming that the observers speed affects the number of miles it will observe during a specific time.)))

There is no way for you to have a perfect absolute constant of 1kg that would always be the exact same. You have no measurable absolute constants in science. You can have hypothetical absolute constants though, but then you will never know if they're truly constants. They just feel constant to you.
Well, once a kg is defined in terms related to the Planck constant, I would disagree. But for arguments sake, OK. So what?

By absolute, as I have now explained 10 times, I do not mean anything other than real, actual, a quality of the universe, in contrast with your original claim that "all mass is relative" and that "mass on the earth is different from mass on the moon".

The same real sized lump of matter will have the same inertial mass regardless of the units we choose to employ - the actual units are trivial, although the need for units of some sort representing the real qualities - mass, distance, and time, is not trivial, but fundamental.

You are basically refusing to concede the obvious because you cannot admit that you were dead wrong in the first place. You fail to understand that an error is forgivable but continuing to defend it makes you look like a damned fool.

It makes me laugh to see you spending days defending your equations but refusing to actually sit down and show a single worked example to back your silly claims. We all know why that is. Even you know you are talking crap.

Put up or shut up - a worked example, proving your case.

How did we get from frequency red-shift to phase shifting. Phase shift keying is one of the tricks we used back in the late '70s to increase BPS over 900 baud copper wires, but has nothing to do with red-shift. Red-shift is the elongation of oscillation frequency.

Wrong wrong wrong.
You are again speaking of the philosophy of mass. I am talking about the scientific concept of mass. Mass in science is virtual, we do not know what mass is and what is its absolute quantity in any fixed chosen measure. All we have are falsifiable hypothetical models that may be absolutely different from the underlying absolute reality. These models work for approximating the effects of mass and that is all that is required by science.
In science mass is only a virtual concept and on the very most fundamental level we don't know if mass actually exists or is just simulated. Science does not care if the universe and mass are simulated, science works inside the simulation and uses hypothetical virtual concepts to model the simulation.
Science actually only tries to simulate the observed reality so if this all is just a simulation, then science is a simulation inside the simulation.
HB, you are still struggling with the most basic concepts in physics. You are confused between mass and methods of measuring mass. So confused that you consider mass as a philosophy.

Once again, mass is a measure of the quantity of matter. Clearly, matter is composed of something, and quantity of that something is a real property. On the most fundamental level you can see this as the count of atomic/subtomic particles constituting the object. However, we have chosen a different unit to express the quantity of matter. And you are finding it difficult to understand that concept.

When you say "science is a simulation inide a simulation" you are once again bringing solipsism into the discussion to prove your point. Why? Do you understand that we have to proceed with the basic assumption that reality exists? Then why are you repeatedly mentioning the solipsistic non-sense? You are clearly trying to fudge the issue.

What is the "decay uner standard model"? If the artifact used to represent a standard unit of mass has problems of its mass not being stable, then that is a technical issue - the solution is to measure the variation, and adopt procedures to ensure stabilty and/or ensure corrections are applied. It has nothing to do with the concept of mass. Already effort is under way to express this unit in terms of a more stable measurement.

Wrong. The calculation is done in the frame of the emitter, not in the frame of the observer. In both frames, the speed of light is c.
