There is a serious objection to the conventional application of

geometric concepts to the notion of time, particularly in the context of

four dimensional space-time. Time is not is not simply an extension of

ordinary spatial geometry, in other words. Everything that happens

happens in the present. We can know of the past and of the future, but

this is only because the present cannot have been what it is and cannot

stay as it is. But the knowledge of past and present are simply

conceptual implications of present circumstances and not capable of

geometric extrapolation in geometric terms.

The modern concept that gravitation bends space in some sense is also

problematic. In point of fact, gravitation bends light not space. And

this suggests to me that the two have a common origin in the nature and

properties of electromagnetic radiation generally. Whether this point of

view will prove tenable remains to be seen, but the concept of

gravitational warping of space cannot be valid.

Space, apart from any mechanical properties imputed to the plenum, is

simply a geometric construct and has very specific dimensional

properties associated with it for this reason. In particular, space is

three dimensional in nature. This is not an option. It is actually a

mechanical limitation resulting from the same considerations used to

demonstrate Fermat's Last Theorem.

It would be interesting in the extreme to see modern string theorists

demonstrate the possibility of more dimensions in mechanical terms. The

usual approach is simply to assert the possibility in terms of

conceptual extrapolation from the first (and only) three and then to

claim the plausibility by analogy with two dimensional phenomena in the

context of three dimensions. However, this does not prove the

possibility of higher dimensions in strict mechanical terms; it simply

asserts that it is not implausible, which of course it really is because

in three dimensions there can only be three dimensional phenomena since

one or two dimensional phenomena can be oriented in any of the three

dimensions.

There is a further discussion of such considerations available at
