Re: [Vo]:Space has no time dimention
I have no problem with lack of a Time dimension but there must still remain at least one additional spatial dimension. The fact that we are confined into a 3 dimensional plane only makes the detection more difficult. What we refer to as future and past becomes blurred by gamma when an object is accelerated toward C or encounters Casimir geometry. Lorentz contraction and the size of time quantum vary such that the observer and the observed both see a portion of the other's space as time [making it contract and dilate]. The fact that all inertial frames remain unaware locally of any dilation or contraction indicate to me that all dimensions are equally spatial but that we are somehow confined like flatlanders on a chalk board. IMHO future and past are a single spatial dimension on either side of our plane always appearing 90 degrees displaced but gamma reveals that our plane rotates into this dimension thru relative measure between different inertial frames. Perhaps 2D flatlanders would experience 2 temporal axis, the one we share and the other being how flatlanders would perceive motion of their chalk board in our 3D world.

RE: [Vo]:Space has no time dimention
I think a satisfying view of time is that the universe consists of Nothing But Motion, the physics of Dewey B. Larson's Reciprocal System -- that is the primary constituent of the universe is a unit of motion which is space/time and it can support 3 dimensions of motion, so space and time are just aspects of motion and both are 3D. This model explains many things that conventional physics has no clue about and enables calculation of fundamental values from basic premises alone, such as planck's constant, lifetime of the neutron, melting points of elements etc. Only three values are needed to perform all calculations: c, the Rydberg frequency, and Avagadro's number. -Original Message- From: Mauro Lacy [mailto:ma...@lacy.com.ar] Sent: Saturday, May 14, 2011 12:48 PM ...Space and time are probably both sides of the same coin: movement.
