the bang

i was wondering about the universe and this big bang thing.

when it went off did it do so with equal force?.as in did it blow out whatever it was made up of equally in every direction?.

if it did then i suppose it would be round like a football but if an equal amount of everything is travelling away from the centre in all directions at the same speed then would identical things be formed at different points at exactly the same time and distance from the centre.

would everything we know that has happened this side of the big bang be repeating itself at the same time at different points all over the universe.

if everything is symetrical could there be an identical galaxy to this one an equal distance in a straight line the other side of the big bang.

as above so below so to speak.
