@Paul1977:
I'm clearly not as well versed as many of you on many of the things you are discussing. I like to think I have something of an understanding of many of the concepts, but not the intricacies.
One thing I have trouble visualizing is the idea that the universe has no centre, or that everywhere is the centre. You think of the Big Bang as an explosion, and so I want to visualise a "ground zero".
And Paul you are right there - Occam's Razor come into play!!!
There are 3 possibilities of how the universe can come into existence.
1. From nothing to something - this is against the universal law of cause and effect and 0+0+0+0+0+0=?
2. Self created - by logic, is this possible? A mother gave birth to herself before she gave birth to you. I mean this is the law of nature
3. External course.
