I have been thinking lately about uncaused effects in QT. Particularly I have been thinking about ways of avoiding infinite regress or closed causal loops.

As I understand it, the Casimer Effect is uncaused, as is Hawking Radiation.

1. Is this so or could these have causes we cannot detect or simply not understand?

I would appreciate someone setting me straight.

On a seperate note:

2. Also, are there an infinite number of points on a one inch line?

And..

3. If it is possible for time to extend infinitely into the past, how can an infinite number of seconds have passed for us to be experiencing this present second? Please someone tell me what I am missing - it's driving me mad.
