    Thanks rpenner...I'm sure you won't mind.....
    As Richard Feynman wrote in “Cargo Cult Science”, “The first principle is that you must not fool yourself — and you are the easiest person to fool.”

    Cut the crap out Paddy using colour to try and stand out, What the hell does that gibberish mean?

    No need to tell porky pies my friend.....
    In actual fact the further away we look the faster is the expansion rate and the larger the cosmological redshift.
    Funny though that you keep trolling me when you claim to have me on ignore.
    That just adds another string to your bow, of your growing list of fraudulent claims.

    Well your opinion is valid, however I think you are talking complete crap and pretending to be a scientist. At the most a lab assistant. You clearly have no idea about relativity or special relativity. Most of relativity is thought experiment, using trains .

    Yes, not 100% readable, sorry.
    "When a redshift of light is observed due to the intervening space expanding, it is a cosmological redshift".

    Sometimes, it just seems like you are trying to be funny, which is really quite sad.

    Word salad, it means nothing and you know nothing.

    The theory of realistic says you are incorrect.

    Cosmological Redshift
    Laboratory experiments here on Earth have determined that each element in the periodic table emits photons only at certain wavelengths (determined by the excitation state of the atoms). These photons are manifest as either emission or absorption lines in the spectrum of an astronomical object, and by measuring the position of these spectral lines, we can determine which elements are present in the object itself or along the line of sight.

    However, when astronomers perform this analysis, they note that for most astronomical objects, the observed spectral lines are all shifted to longer (redder) wavelengths. This is known as ‘cosmological redshift’ (or more commonly just ‘redshift’) and is given by:

    for relatively nearby objects, where z is the cosmological redshift, λobs is the observed wavelengthand λrest is the emitted/absorbed wavelength.

    Caused solely by the expansion of the Universe, the value of the cosmological redshift indicates the recession velocity of the object, or its distance. For small velocities (much less than thespeed of light), cosmological redshift is related to recession velocity ( v ) through:

    where c the speed of light. At larger distances (higher redshifts), using the theory of general relativity gives a more accurate relation for recession velocities, which can be greater than the speed of light. Note this doesn’t break the ultimate speed limit of c in Special Relativity as nothing is actually moving at that speed, rather the entire distance between the receding object and us is increasing. This is a complex formula requiring knowledge of the overall expansion history of the universe to calculate correctly but a simple recession velocity is given by multiplying the comoving distance (D) of the object by the Hubble parameter at that redshift (H) as:

    Although cosmological redshift at first appears to be a similar effect to the more familiar Doppler shift, there is a distinction. In Doppler Shift, the wavelength of the emitted radiation depends on the motion of the object at the instant the photons are emitted. If the object is travelling towards us, the wavelength is shifted towards the blue end of the spectrum, if the object is travelling away from us, the wavelength is shifted towards the red end. In cosmological redshift, the wavelength at which the radiation is originally emitted is lengthened as it travels through (expanding) space. Cosmological redshift results from the expansion of space itself and not from the motion of an individual body.

    For example, in a distant binary system it is theoretically possible to measure both a Doppler shift and a cosmological redshift. The Doppler shift would be determined by the motions of the individual stars in the binary – whether they were approaching or receding at the time the photons were emitted. The cosmological redshift would be determined by how far away the system was when the photons were emitted. The larger the distance to the system, the longer the emitted photons have travelled through expanding space and the higher the measured cosmological redshift.
    :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

    So there we have it children.
    The universe is most certainly expanding and actually accelerating in that expansion rate. That observation is beyond any reasonable doubt.
    But be careful...Fools abound that like to claim otherwise!

    OMFG--are you serious?? you have now shown yourself too be nothing more than an mentally disabled, pathetic parasite.
    in my irrelevant opinion, this deserves a ban.

    Paddy, do you know what an object is? Do you know what space is? Do you know the difference?

    The doppler red-shift is observed of the reflective light of a body in motion moving away from a light source at the said near speed of light, do you not understand that the theory of realistic says that space is not expanding because is contracting, provable because space has a pressure.

    The theory of realistic says this about space time

    The ''virtual rubber ball'' theorem

    What goes up , must come down, each action has an equal and opposite reaction, like the stretching of an elastic band will have imposed by its own mechanism an equal and opposing force to the force of the expansion, until the elastic band eventually breaks by an inequality of greater stretching force. To break free from the earth's gravity there has to be an inequality of force, an escape velocity has to be reached, an opposing force to gravity, a greater magnitude of a stretching force, compared to the lesser magnitude of the contracting force of gravity.

    Travelling at a velocity away from a light source at the near speed of light, the light that is following you becomes stretched. Travelling at a relative velocity to a gravitational influence even your time becomes stretched. Travelling away from an inertial reference frame even the distance between you and the starting point is stretched, the space between you and the starting point expands .

    Observe any object that can be moved, move the object, observe how light and space fills where there was no space and no light.

    Imagine a concrete existence inside of a virtual rubber ball............once something concrete is displaced, the virtual rubber ball is displaced.

    i am not sure of the significance of your psychological link, which i think you mean " realistic conflict theory?" if not, then WTF is this " theory of realistic " that you are referring to?
    also-- please provide a link or such too something that claims this : " that the theory of realistic says that space is not expanding because is contracting "

    Busted, I'm out of here, read my theory when it gets released, it explains gravity, negative mass, positive mass, and just about everything. I have spent ages over on Cambridge University ''Naked ''scientist forum, and learnt a whole lot more . If anyone wishes to continue and know more you can find me over there.

    So what, the theory of realistic is just ignorant tripe.

    you sure are.

    (shrugs)
    all of the sudden, after i have exposed your website?--odd.
    it appears that whatever you are continuing to tell yourself is simply not working.
    according to whom though, you?--comical.
    i think it is pretty clear that none are interested.
