Heaven located (maybe)

New mathematical or scientific ideas often provide material wihich believers in life after death can adapt to provide quasi explanations for the supernatural world. Spiritualism for a long time clung to the idea of "higher vibrations" as being the context in which souls lived. This always sounded a rather silly idea to me, but I'm sure you can still find lots of allegedly channelled books in New Age outlets which talk of spirits having to lower their vibrations to talk to mediums.

I was always keener on the idea of higher dimensions. Ever since mathematicians started thinking about them, the religiously inclined have wondered whether this is a good explanation of a physical location for Heaven, or other (formerly supernatural) realms. Science fiction writers liked the idea too: Heinlein's "And He Built a Crooked House" comes to mind as a fun short story. Other dimensional worlds feature often in his novels too, now that I think of it.

I see from Googling that a physicist priest (William Pollard) as late as 1961 was writing a book explaining higher dimensions as an important religious idea. From a review of his book in Time:

"The key to this approach," he writes, "lies in conceiving the whole space-time continuum of our human intuition as being immersed in a space of higher dimensions." The reality of a higher dimension than the three of space and one of time may seem somewhat elusive to ordinary human beings, but modern scientific minds can see it as mathematically just as sound.

A higher dimension is the result of a lower one moved perpendicular to itself. Writes Pollard: "Heaven, instead of being above us in ordinary space, is perpendicular to ordinary space, and the eternal is perpendicular to the temporal dimension. The transcendent and the supernatural, instead of being pushed farther and farther away from us with each new advance in astronomy, are again everywhere in immediate contact with us, just as the dimension perpendicular to a plane surface is everywhere in contact with it, though transcendent to it."

It's a appealing idea, and it always seems a pity to me that modern science seems to have no use for it. Of course, we hear about extra dimensions in string theory all the time, but mostly in terms of the extra dimensions being bound up so small that they are virtually undetectable. The related idea of branes suggest that there might be another dimensional world just a fraction of a millimetre around us all the time, but while branes can affect each other, as far as I know they don't suggest any way for life from one brane to correspond, or transfer, to another "nearby" brane.

But today I happened to buy last month's Discover magazine, and in the article on black holes, they had an extract from Brian Greene's recent book "The Hidden Reality." This was talking about whether our universe is like a holograph of information processing happening elsewhere.

The phrase "holographic universe" has been around for quite a while; I think I have on my shelf the popular book of the same title by Michael Talbot. (I see now that he died in 1992.) But this was mainly about the ideas of David Bohm and Karl Pribram, and the physical detail of how this type of universe arises was left vague, as I recall. An article by Talbot which explains his books themes can be found here.

I have heard before of black holes and holography, but I think the Brian Greene extract explains it in a relatively clear fashion. Here are some of the relevant parts (typed by me, as I can find no link):

Plato likened our view of the world to that of an ancient forebear watching shadows meander across a simly lit cave wall. He imagined our perceptions to be but a faint inkling of a far richer reality that flickers beyond reach. Two millenia later, Plato's cave may be more than a metaphor. To turn his suggestion on its head, reality - not its mere shadow - may take place on a distant boundary surface, while everything we witness in the three common spatial dimensions is a projection of that faraway unfolding. Reality, that is, may be akin to a hologram. Or really, a holographic movie.....

For black holes, we've found that the link between information and surface area goes beyond mere numerical accounting; there's a concrete sense in which information is stored on their surfaces. Physicists Leonard Susskind and Gerard't Hooft stressed that the lesson should be general: Since the information required to describe physical phenomena within any given region of space can be fully encoded by data on a surface that surrounds the region, then there's reason to think that the surface is where the fundamental physical processes actually happen. Our familiar three dimensional reality, these bold thinkers suggest, would then be likened to a holographic projection of those distant two-dimensional physical processes.

If this line of reasoning is correct, then there are physical processes taking place on some distant surface that, much as a puppeteer pulls strings, are fully linked to the processes taking place in my fingers, arms, and brain as I type these words at my desk. Our experiences here and that distant reality there would form the most interlocked of parallel worlds.

Well, the thing that struck me when reading this was that the idea might, with a bit of pushing around, provide possible ways for arguing:

a. we all are embedded in a "higher" realm which we cannot see (even if the "bigger" reality might be a two dimensional surface rather than a 4 spatial dimension universe);

b. the information processing taking place on the distant surface (presumably of the big black hole the universe is enclosed in) could provide a way for individual minds to survive death. I mean, does the information processing happening on the distant surface have to produce a holographic "image" of a body and its incorporated mind in our world? If a body dies, can the information that effectively produced the mind continue working on the two dimensional surface?

In other words, this seems to provide a location for Heaven, of a kind.

Mind you, if we're talking the surface of a black hole, this is not a permanent place, if Hawking radiation would see it slowly evaporate. (But then, it still remains to be seen if Hawking Radiation really exists. There are still some legitimate doubts.)

OK, so it's not a perfect explanation, but I like any idea that gets us away from mere materialism and lets the information that is our minds have an "out of body" aspect to them.
