It is often said that at the initiation of the known physical universe that it occured at a dimentionless point. How can this be so if at that point, (avoiding "moment") there was no space (or time)in which to define a dimentionless point? Space is required for any description of dimention.?
Chicken & egg. Space or Big Bang first?

There had to be two chickens before there was one egg, and yes God put them there to do just that...so when God created the universe through the "Big Bang" there wasn't a space there, cause God hadn't created the Bang yet, the Bang created the space...just my humble thought...enjoy

Bigbang is a bad theory or a funtastic theory. the inventer of this theory was a mental man. human brain cannot accept this rediculous theory.

I am interested to find out how you see it. Can you do so?
I am also pondering a loop of time I perhaps interaction with other dimentions which are acknowledged but don't seem to ever be included in explanations within cosmological conunderums.
