as for time, i think it is totally subjective to who is observing it.

Thanks, magnus. Yes, that is a problem I have been trying to encompass. In GR, it seems there is no such thing as simultanaety. No two clocks can ever really be the same. I find it very difficult to let go of the notion of coinstantaneous events, perhaps because I have already let go of so much else.
Much of eastern thought seems to me to be directed toward a social entity and its needs, where western thought is centered on the individual. I have been raised in the western tradition, so notions of the egoless state of nirvanah and such seem mysterious. Strangely, both traditions lead to the same impasse, where persons are allowed to adopt the position of "I've got mine," that is, I feel great, your suffering is an illusion. In the west, we become wealthy and shut out all that is unpleasent. Few seem bothered by the loss of depth and wisdom and human experience that comes from living within established walls. In the east, people are encouraged to find mental states that transcend personal suffering and detach the self from responsibility for worldly catastrophe. The result is less socially devastating (monks meditating in cells take up less resources than jet setters) but poverty and desperation are still not relieved, merely accepted as part of the natural process.
Well, back to physics, it seems to me that every observation requires three things, an observer, a process to be observed, and a universe in which the observer has some commonality with the process. Because the observer and the observed are in the same universe, any change in one necessarily entails changes in the other. Therefore there can be no logical consistency in separating the observer from the observed, even though we must assume a separation, an "objectivity", in order to cause events to turn to our satisfaction. This works great for cannonballs but becomes a problem in quantum realms. Perhaps I should say, rather than problem, an opportunity.
Anyway, one must adopt a self in order to observe the other. Self then must make decisions about the boundaries between self and other. These decisions determine the outcome of the observation. There seems at first glance to be no way out of this quandry. However, in multiverse interpretations, the universal set of each self is different from the universal set of other selves. Infinite or bounded, no two universes are exactly alike. Having defined a self, one has defined the universe that self exists within. Or, having sufficiently defined the universe one exists in, one thereby defines the qualities and conditions of the definite self.
In practice, self has to have limits. Self is particular, and has size. The size of self establishes quanta...It is not possible for any universe to be larger than some finite number of selves. Having established that the universe is of a certain largeness, it has to follow that there is also some certain smallness beyond which the limits imposed by self cannot go. It is not a coincidence that the Planck space and the Planck time are related by the speed of light. However, I am still puzzled about the exact numbers. How did Max Planck know, a hundred years ago, how large the universe is?
It seems to me that there may be considerable room for adjustment in the choice of numbers, that is 10 E-27 cm and 10E-43 s. Quantum effects occur at much larger scales...even, in the experiments in Colorado with Bose-Einstein condensates, up to the visable scale. It is certain that quantum effects are prevalent on the scale of the proton, a mere 10E-9 cm.
For this reason I suspect that the universe is much smaller than Max Planck thought it was, and the size of the minimum quanta is much larger. Or, the universe is much younger, which, in inflationary terms, is to say the same thing.
I seem to recall that results of the cosmic microwave background measurements indicated an age of about 13x10E9 for the universe. Multiply that by c to get the current size of the universe. The minumum size observable then is as much smaller than we are as the universe is larger than we are. Let's see, 10E9 lightyears, what is that in meters? Memory fails me yet again. Uh, 3x10E9 m/s, x60 x60 x24 x365 is what, 6x10 x6x10 x2.4x10 x3.65x10x10x10, that would be, uh, 3x6x6x2.4x3.65x10E9+1+1+1+3 is about 108x2.5x3.5 is about 108x10 so 10E18 meters? So by my logic the Planck length should be about 10E-18 meters, or 10E-19 cm. My innumeracy has given me a headache so please forgive me if I leave it at that.
Now I wonder what the mentats would make of all this. Any comments? I have to go patch my roof before the next hurricane hits.
Thanks,
