THE NATURE OF SPACETIME

<1>

Below, I present an outline of ideas:

 

***

 

<2>

-- The objective world is four-dimensional, not three-dimensional.(1)

 

<3>

We can distinguish between two different types of spacetime: Type I and Type II.  In a Type I spacetime:

 

-- There is no "past-present-future" distinction.

-- All spacetime events (SE's) have the same existential status.

-- All SE's are equally "present."

-- All SE's are real. (The past is still real; and the future is already real.)(2)

 

<4>

In a Type II spacetime:

 

-- There is no "past-present-future" distinction.

-- All SE's have the same existential status.(3)

-- No SE is ever "present."(4)

-- SE's exist as "quantum possibilities."(5)(6)

 

 

***

 

<5>

-- In order for a spacetime event, s1, to be real, s1 must possess the property of being "present." If s1 lacks "presentness," s1 is not real.  -- If all spacetime events lack "presentness," all spacetime events are unreal.

 

 

***

 

<6>

-- A Type I spacetime is not logically possible.(7) However, a Type II spacetime *is* logically possible.(8)

 

 

 

Notes:

 

1. In addition to the objective world, there is a subjective world (i.e., 3D phenomenal space).

 

Each mind perceives its own 3D, virtual reality.

 

2. The spacetime of general relativity is "Type I."

 

3. Philosophers often claim that human "free will" is not possible in a Type I spacetime.  (See TA48 by V. Petkov [Karl Jaspers Forum]:  <http://www.kjf.ca/48-TAPET.htm>.)

 

I suggest that "free will" is possible in a Type II spacetime.

 

4. The "present" is a subjective phenomenon associated with consciousness.

 

5. In a Type II universe, spacetime events are not "real."

 

6. In his book *Other Worlds*, Paul Davies questions the reality of the unobserved, objective world.

 

In the book, Davies considers both the "realist" and "Copenhagen" interpretations of superspace. <http://deoxy.org/superspace.htm>

 

7. The past cannot still be real. And the future cannot already be real.

 

8. Our 4D world is a Type II spacetime. (See [Time] messages 13777 and 13780: <http://groups.yahoo.com/group/time/message/13777>,  <http://groups.yahoo.com/group/time/message/13780>. See also TA48 by V.  Petkov [Karl Jaspers Forum]: <http://www.kjf.ca/48-TAPET.htm>.)
