- Your (Mark Schlegel's) objection is based on a number of assumptions:
-
- 1. Time is a single linear dimension.
- 2. Time proceeds forwards from past to future.
- 3. An event at time t1 can only cause an event at time t2 if t1 < t2.
-
- It may be the case that one or more of these assumptions is not the case.
- Stephen Hawking's "A Brief History of Time", for example, puts forward the
- suggestion that time is two-dimensional, but that we only perceive one
- dimension. That is, it's like a complex number where we only perceive the
- real component. This allows the possibility that the universe is finite but
- unbounded -- it simply has no beginning or end, time is a loop. In such a
- model, we see a singularity at the universe's beginning because at that
- stage, time is entirely imaginary (in the mathematical sense).
-
- And now, on to Dave Weaver's objections to Mark Schlegel's comments about
- uncaused quantum events...

-
- It may not say that all quantum events are uncaused, but what is the cause of
- virtual pair production, for example?
-

-
- I'll stomp on this one quickly: QM is *not* about observational interference.
- That there's a particle with a definite position, but that you cannot measure
- the position accurately, is a common misconception. A photon with a given
- wave function does *not* have a single particular position within the space
- occupied by the wave function. In the two slits experiment, in an inexact
- hand-wavy sort of way each photon "goes through" both slits.
