Re: The 'Super Anthropic Principle' - why multiverses are not needed and thus very unlikely
Spudboy, Good question. It has to be clearly understood that an observer is always a participant in the event he observes. An observation is always an event. Physics tends to think of observers as standing outside the events they observe, but what they really do is participate in subsequent events to the particular event they imagine they are observing. E.g. a human observer does not actually observe the quantum event he is usually talking about except through a chain of other events terminating in his visual participation with a measuring device, which is of course another set of quantum events, since all events are quantum events. So, in a general sense, all participants in every event, even down to the particle level, act as observers of that event, and information about events flows computationally through networks of connected events. In my book on Reality I call this 'The Sherlock Holmes Principle' and it is the basis of all knowledge, both scientific knowledge and the knowledge of direct experience.

Re: The 'Super Anthropic Principle' - why multiverses are not needed and thus very unlikely
On Thu, Dec 26, 2013 at 7:49 AM, Edgar L. Owen edgaro...@att.net wrote: Hi Jason, The STc Principle conclusively falsifies block time, since the fact that everything continually travels through spacetime all the time requires everything to be at one particular position in spacetime all the time. Things can have a world tube that grows one light-year in length per year. You seem to be envisioning things as single points. This is confirmed by direct experience, that we are always at a single point in spacetime. Direct experience is a rather shaky foundation on which to build a theory. Remember how it worked out for the geocentrists. How could it be otherwise? Can direct experience rule out the theory that there are two moving presents that exist, one-day apart, such that you experience every moment of your life twice? The notion of block time is based on a misunderstanding of SR. Believers in block time need to offer an alternative explanation (than the one I give above) for the self-evident fact that we all experience our existence in a common present moment which they are unable to do. All observers believe the time they inhabit is the present, it is as true for the fighters in World War I who believe 1914 is the present, as it is for you and me who think 2013 is nearly over, as it is for our descendants who believe 2500 is the present. Think of it like this: If the past doesn't exist, then they are wholly unnecessary to explain your current experience of the present. In other words, the present moment is entirely sufficient, on its own, to explain your experience of now. But then, if the present moment alone is entirely sufficient to explain your experience of right now, then whether past moments in time exist or not should have no impact on your experience of right now in this present moment. Presentism thus rules out its own justification for presuming that past moment's must no longer exist in order to justify our experience of right now. Again in your subsequent discussion about Bob and Alice you are discussing well known effects of SR with regards to CLOCK time. It isn't just times on their clocks, it is what they can infer is happening at different points in time based on their assumption of the constancy of the speed of light. When Bob does the calculations assuming the speed of light = c, he finds event B had to happen before A, and when Alice does the calculations, she finds event A had to happen before B. How is this compatible with a single objective present? But the point I keep hammering home is that all these SR effects occur to every observer only in the present moment. You seem to assume there is the present moment, rather than their present moments, but this seems to be an unnecessary complication of the theory. And when any observers meet up they always share that same present moment, therefore it must be common and universal. What is your definition of present moment? What do you think about the http://en.wikipedia.org/wiki/Rietdijk–Putnam_argument ? Of course Bob and Alice have different relativistic views of clock time, but everyone of these views occurs always in their present moment, and these present moments are always exactly the same whenever any observers meet up anywhere in the universe, therefore it is clear that present moment must be common to all observers. You are extrapolating from the idea that when two observers share a where they share a when, to get to the idea that whether or not observers share a where, they share a when. The first assumption doesn't even seem true, however, in the context of the Rietdijk-Putnam argument. Even two observers at the same place, if they are walking past each other, exist in when's that contain different content. Jason Edgar On Wednesday, December 25, 2013 11:52:10 AM UTC-5, Edgar L.

Of course Bob and Alice have different relativistic views of clock time, but everyone of these views occurs always in their present moment, and these present moments are always exactly the same Exactly the same as what? The same as the moment they meet - sure? The same as the moment that others are meeting at other spacelike events - no.

Re: The 'Super Anthropic Principle' - why multiverses are not needed and thus very unlikely
Amen on most points, Edgar. I also have misgivings about the existence of the multiverse for different reasons that this posting is not the place to vent. But, for we humans, the present moment exists for each of us. Your "common present moment" is an assumption that all x, y, and z of this 3-D realm experience simultaneity, even though every local set of coordinates, for instance, x1, y1, z1, if they have a self-aware structure (SAS), i.e. an observer, will have different experiences - albeit, even if only that the coordinates are different. You are trying to make your "common present moment" an axiom of reality that, for all x, y, and z, there is only one t. Though it makes common sense for a strictly Newtonian universe, when one adds relativistic considerations of the connectivity of space and time into a space-time continuum, your axiom of a common present may not hold. I am, BTW, a physicist by education. I don't post much. Howard Marks Certainly, your assumption can be made and explored. On 12/25/2013 10:52 AM, Edgar L.

Re: The 'Super Anthropic Principle' - why multiverses are not needed and thus very unlikely
Hi Howard, Your comments pertain (correctly) to clock time but not to P-time, the time of the present moment. It is clear that the t's of clock time differ between clocks according to relativistic conditions. You need to understand that the present moment is independent of any particular clock time, it is the common present moment WITHIN which all clock times may have different t values. When the space traveling twins reunite with different clock time t values they ALWAYS reunite in the exact same present moment. That's the key insight I'm trying to get across.

All this stuff about time is attempting to solve a problem that doesn't exist, or at least hasn't been shown to exist.
