I don't know the answer but have some questions comparing a spaceship with a photon. If we were to continuously push a spaceship we could increase its energy and maybe, though far fetched, have it approach but not quite reach c. (or push a particle around an accelerator.) I.e. we can create, over a finite non-zero time, a mass moving at near speed c. But a photon can only move at speed c. We cannot slowly accelerate it until it reaches speed c. It must jump from non-existence to moving at speed c instantaneously. Assume that this were not the case. We run into trouble as the device or process creating the photon in an assumed interval of (say) one second has to catch up with the photon moving at speed c in order to complete the creation. If the process was not completed after 1/2 second, the creator could not catch up with the half formed photon as it would have to catch up with something travelling at speed c. Which is impossible. So it must be created in the first instant. (I would say created in or within a single planck length time in which it occurred, rather than in zero time) E=hf does not mention time, I presume, because the energy of a photon is constant over time. Its energy cannot be increased or decreased over time as it cannot travel at anything other than speed c. I agree that there are peculiarites with respect to photons and time. Possibly this involves extra dimensions, but that is just a speculation. There is a limit to how much we can understand through common sense analogy, though I feel we have to try. But it is not enough on its own. The trouble is that common sense is very misleadingly simple. 3-D is only common sense because it seems natural to our everyday lives. But the trouble is once you start creating dimensions, when do you stop? Why stop at 3, or 4 or 8 or 16 or at anything short of infinity? What is so special about 3? Once the universe starts creating dimensions, I don't see how it can logically stop at any finite value. > 3 > my abstract is in > > http://www.google.com/url?sa=D&q=http://sites.google.com/site/theyporatmodel/an-abstract&usg=AFQjCNFTvin3DZBasiMyWO4uOJxzQM0T1w I have found it and will look at it closer soon.

Putting aside quanta for a moment and instead assuming that space and time are infinitely divisible into pieces as small as you like. Then how can we observe smaller and smaller pieces? Using light microscopes takes us so far. Blue light should enable us to resolve finer details because it is more energetic than red light. Using E=hf for a 'blue' photon gives (say) twice the value for f that it does for a 'red' one. (Though colour is not a property of the photon.) The reciprocal of f is the wavelength, so the wavelength for blue light is half that of red light, so I think that explains why blue light gives a clearer understanding of details (hence Blu-ray?). Beyond that you need an electron microscope. But the ultimate instrument is the universe itself? First estimate E for the universe from mcc with a guess at the mass of the universe (wiki gives estimates). Then use E=hf to estimate f for the universe. The reciprocal of the f should be the wavelength of the universe (that sounds odd to me!). As E is very big, the wavelength will be very small. As I understand it, the calculation of that wavelength should equal the Planck length? Since there is nothing available to us which bigger than the universe, then we have to stop there. We cannot observe details smaller than that. Not necessarily because there are no smaller details, but because we have no way of measuring them. So now we are saddled with the quanta again. Also, the Planck time should be able to be derived from c = planck length / Planck time, I think. If our universe had been ten times bigger than it is, then we should be able to see ten times clearer than now? But I don't think that would help with queasiness about the idea of instantaneous events. I don't like the idea of instantaneous events either, but there is no alternative I fear. But I rationalise it for myself by thinking that it can take place within the space of one quantum label of time. And there are unknowable depths within one quantum of time. Whether or not a single quantum in our universe is in fact bigger than one that could have arisen in a bigger universe may, I suppose, be disputed, but we cannot measure within it with this universe.

But an analogy is Pythagorus's attitude to irrational numbers. You can build a mathematical line out of an infinite number of fractions, yet even though you define the line in fractions, non-fractions arise from seemingly nowhere. But, most of the numbers that are useful have labels. It is easy to label fractions, but not so easy to label all the non-fractions, though there are some special ones with labels, eg pi. But by all means, yes, concentrate on the matter/mass. > btw > you should know that there are even simpler > and more 'primitive' physical entities than photons!! > it is "gravitons ' or neutrinos etc !! > while no one even expect to 'see' them Agreed, I was not being complete in listing all known possibilities. > > Using E=hf for a 'blue' photon gives (say) twice the value for f that > > it does for a 'red' one.

Again, true. I nearly added a extra idea to that statement as to where the universe in the equation begins and ends. E.g. Is it just the observable universe? The BB? The part of the universe which can interact with us? What? > First estimate E> for the universe from mcc > > sorry i dont knoe what is mcc ?? > --------- > with a guess at the mass of the universe > -------- > who can know the mass of the universe ?? > it sound fantastic ! Apologies, I just meant E = m c squared. The basic word editor over- taxed me. > but not all masses are defined by > E=hf > there are the gravitns' black matter etc > that we know very little about them I don't know enough about that to try to include them all. And I was using E=hf regardless of legitimacy and maybe out of context. It would probably be OK to include dark energy which is supposed to be quite a sizeable chunk of the total energy? I also said that I was putting aside quanta for a while but then went straight on to use a quantum equation E=hf. Oops! > we dont have to go so far for understanding > instantaneous or not I am not at all sure about this. Either, assuming quantum effects, how do you get from quantum 1 to adjoining quantum 2? It has to be instantaneous? Or, dropping quantum effects, how do you get from any point 1 to a point 2, when there are an infinite number of points intervening? This is the paradox raised by Zeno. I don't understand it perfectly. The maths answer is, I believe, to say that you can take an infinite number of steps in a finite time. For example, the infinite series 1/2 + 1/4 + 1/8 + 1/16 etc etc adds to a finite total = 1. But that is only OK as long as you are not labelling all the terms of the series as you add, as you cannot stick separate labels on an infinite number of terms. I don't really like either of the options. > and you cant that anything is happening instantaneously > yoiu have no experiental tool even to detect > it and say > it was instananeous > on the other hand > we canknow that time is actually > motion dependent !! > and that is good to tell yus that > no motion no time- nothing happened Not clear about this last point? |
