- Correct, with a slight modification: I accept these assumptions for all
- effects occuring within this universe, excepting #3 for the big bang.
- I assume causality holds, and since the big bang event occurs at t=0,
- it's cause would be extra-dimensional.

- "Brief History" is near the top of my "to read" list. But I am somewhat
- familiar with his arguments, as I have read a couple of commentaries on
- the work. As physicist Frank Tipler notes,
- "... a four-dimensional sphere of zero radius forms a boundary to
- Hawkings universe. ... He [Hawking] has eliminated the classical
- singularity -- the beginning of time -- only to have it re-appear
- as the "beginning" to the space of all possible four-spheres."
- A quantum singularity is substituted for a classical singularity, and the
- problem of "beginning" is not eliminated.

-
- I have no idea, and I take it from the question that no one can say for
- sure. Again, does that mean that this effect is uncaused? I for one, am
- not quite ready to throw causality under the bus.
-

-
- Point taken. That's why I asked for physicists to help out.

-
- I'll take your word for it. This, however, is the first time I have seen
- it discussed here. Not all of us are old-timers on the net.
