Anyway, it turns out this theory of mine isn't new - it's called the block universe theory, and apparently one author refers to the 4th dimension as "pime", to distinguish it from what he considers a figment of the human consciousness called time.

There is no such thing as 'movement' in time .. it doesn't make sense as an expression.

Probably wise, as "time" has so many connotations

No it is not .. YOUR definition of cause is nonsense, in that it does not define 'cause' at all. What you have given a definition of is 'past' .. not 'cause'. Try this definition: * A person or thing that acts, happens, or exists in such a way that some specific thing happens as a result; the producer of an effect

I am confused, because as I understand the concept (please correct me...), tick 3B will indeed precede 2A, if before tick 1A, clock B had been to near the speed of light and then returned to earth (in both speed and time), such that 2B had already occurred before clock B returned to earth (and before 1A).

If so, > you've not really understood physics Obviously I don't think that, because throughout this thread I've referred to "movement along the 4th dimension". What I am challenging is that we are constantly moving forward in time *at all*. |
