RE: Story of Everything - Part 1
I guess string theory might give us answers to what happened before the big bang or what really caused the big bang. First we need to assume the existence of a multiverse. A big bang is caused by a collision of these universes thus conservation of energy.
But of course we have to assert the existence of strings and other 11 dimensions for the multiverse to exist. Thats what I know so far. Correct me if I’m wrong with string theory
To my mind string theory is nothing more than fanciful speculation with no supporting evidence (at least none that I know of). Calling it a theory is un-scientific for that very reason.
But even if we assume there is more than one Universe (which in itself is somewhat of an oxymoron} since the word "Universe" implies everything that exists and by definition there can't be more than one "everything that exists" so any other "Universe" would simply be part of the Universe.
But even if there were more than one of what we currently call the Universe at least two would have had to exist before any big bang if this"collision" was to take place. Unless a Universe collided with a singularity or two singularities collided with one another.
LOL this is bordering on the ridiculous and verging on insanity.
However, I believe the real reason why we come up with all these notions of how the Universe might have come into existence is because we can't or won't accept the notion that something could exist in perpetuity i.e. it always existed so it didn't have to be created. And if conservation of energy holds true then this must be the case.
I understand this is a very difficult concept for us to wrap our heads around since everything we're familiar with has a beginning and an end. However this doesn't necessarily apply to the Universe.
According to Occam’s razor the simplest explanation is most probably the correct one and to me the Eternal Universe is much simpler than all the others I've come across.
Even the notion of the collisions of multi verses doesn't in any way address or solve the question of how they might have come into existence in the first place. :)
The same as you I was asking the same question. Due to relativity’s prediction of an initial singularity. Physics could not go beyond the singularity since all of physics equation does not apply. But with the string thoery we can at least know that there may be parallel universes out there plus there is the possibility of uniting the four fundamental forces and understanding them in smaller scale.
