Only recessive velocities have been measured. The acceleration is infered by the model of the universe used.

If the bigbang is in fact the expansion of a black ring (black holes are particles) in a larger universe, you should be expecting these observations. Still, it is a mostly homogeneous expansion...

I know it can seem actractive to take each observation in a vacuum and come up withdifferent ideas, perhaps even using different models of the universe. But when its put all together is why they make the statements that they do and as such your assertion is more wrong than it is right.

My assertion is 100% correct but still, the current model may be right. The truth is, if you don't look for something, you will probably never find it, and that is what most people do. The world goes where the majority goes...

Singularities are impossible and the current model is based on them, that is an actual fact.

..that is what most people do.
Not in physics! That's never been my observation. Never have I met a physicist who doesn't look.

According to theory, a mirror can absorb energy from virtual photons onto its surface and then re-emit that energy as real photons. The effect only works when the mirror is moving through a vacuum at nearly the speed of light — which is almost impossible for everyday mechanical devices.

http://www.nature.com/news/2011/110603/full/news.2011.346.html

My question is ,If mirrors could do so then what is the deal with length contraction ;if this happen in real world running a mirror close to speed of light? Could someone explains please ?

Cheers
Someone just explained some of this stuff to me and made an excellant point. He said

I think it is possible.  But notice that it DOESN'T happen in a vacuum---it happens in the vicinity of a mirror, which is entirely different.  The answer to your (good) question is: moving at nearly the speed of light WITH RESPECT TO THE OBSERVER.  The whole notion of "radiation" depends on the motion of the observer, and the mirror might very well NOT radiate in a system in which it is at rest, and yet radiate in a different system in which it is in motion.
I knew of the frame dependance of radiation but forgot it. This makes a good point.

Thanks JP, it reconciles my theory with QM. But everyone should, at least, admit that there is still the possibility that virtual particles do not exist, because they have never been measured directly. Virtual particles exchanged from one particle to another is quite probable, but popping out from vacuum is less likely.

Pete did you really take time to read my theory?

When I speak to high-energy physicists they do not speak of them as being real but merely as tools in aid to calculations in elementary particle physics. I also don't see any justification for this

I just took a look at it. I see no justification for your assertion It seems evident that light is the basic building block of everything. In fact I'd say that it's quite wrong. Later you speak of a "photon wave" as if a photon were something that has a extension in space. That would be a misunderstanding of quantum theory.

I will answer in my theory because JP may loose his temper...  :o  :o)

I know you're joking, but I'm with JP. It's good to accepted theory with new theories drummed up by posters. All of such posters believe their theory belong in the same place as with accepted theory. However that would make things very confusing for readers. Of course I've seen people get carried away with that. I've seen some Bozo's claim that my view on the concept of mass should be talked of only in the new theory section when in fact my views are the same as what can be found in many modern physics texts. Now that kind of thing pisses me off to no end.

Yes, i understand. As long as people understand the main educative mission of the forum and act according to their level of knowledge.

re - "I will answer in my theory because JP may loose his temper..." - You haven't answered though.

Let's talk about it here. There's no problem with that. Your statement "Matter can be convert into light and light into Matter." is basically true. To be precise one has to have more than the matter to be converted. One has to have something to do the converting. E.g. to convert an electron to radiation we'd need an electron and positron and let them annihilate each other. Then there’d be two photons in the end. But it's impossible to change an electron into a photon and have nothing else going on. The laws of physics, namely the conservation of charge and momentum, have to be observed. Changing an electron into a photon would violate both conservation of charge and momentum.

Re – “A quantum of light (a photon), may possess an infinitesimal energy and always travel at C in vacuum.” – why do you say “infinitesimal.” A photon can have as much energy as you’d like. You name it. All you have to do is change the frame of reference that you’re in. Gamma rays are quite energetic, quite far from infinitesimal. In fact infinitesimal energy isn’t even a finite value of energy.

Re – “It seems evident that light is the basic building block of everything.” – this is a vague statement since anything could be called a “building block”. You have to be specific. If you mean that electrons are made of photons then you’re wrong.

Re – “f a photon wave enter a highly curved spacetime region, it could catch its tail: the wave could close on itself.’ – impossible since the length of a photon, for all practical purposes, is zero. A photon is a point like object with no spatial extension in space.

Re – “I have been thinking about this for many days now and i don't see any contradiction with existing proved theory that could deny this theory.” – what exactly is this theory? I don’t’ see anything unique here except the assertion that light is a building block of matter.

It's about frames of reference that one. In its own frame (assuming a observer being at rest with the 'moving mirror') there is no length contraction. For a far observer not being at rest with the oscillations the length contraction will exist. So in its own frame of reference there is no length contraction to be verified locally and experimentally.
=

You might argue that the universe in one direction, alternating with the oscillations direction locally, should shrink though, and that this can be seen as indirect indication of a relativistic effect but that also assume that the local observer is well read on relativity.
