The Universe and Everything

Question from Bryson:
So based on scientific evidence the universe at one time began to exist right? Explained by What we call the big bang theory. Another law is whatever begins to exist has a cause right? As in there’s something that begins to exist, there’s a cause for it, it existing being the effect. So if a universe existed, logically there’s a cause. Since the universe hasn’t existed yet, there’s no time/space/energy. Which leads to the conclusion that the cause of this “big bang” has to be something outside the laws of time/space/matter.

Well since only two things fall under this category, one would be a divine entity, the other an abstract object like the number 1 or something. My question is how would something abstract be a cause? I know Stephen Hawking said something along the lines of because of the laws of the gravity, there is no need for a creator because that proves the universe will create itself from nothing. But, of course, after thinking about it, if the universe hasn’t existed yet, that would mean the laws don’t exist yet. Plus, while the laws of gravity are describe gravity, it has no creative power. If put 1 dollar in the bank, and then next week 2 dollars, I can logically and mathematically explain why I now have $3. But, if I put 1 dollar in the bank and depend on mathematics to increase it, I would never have more than $1.

I know some people have even talked about something to do with a multiverse, but of course that doesn’t disprove god either because logically with a being capable of creating one universe, why would he not be able to create more if it wished.

Answer by SmartLX:
The good old cosmological argument. This argument falls at the first hurdle, but drags on and knocks over all the others regardless.

– No, scientific evidence has not established that the universe began to exist. It has established that it was once concentrated at or near a single point, then expanded outwards. The evidence says nothing about whether the matter and energy in that point was created at that instant or it got there from somewhere else.

– There are two modern perspectives on matter and energy. According to the classical laws of conservation, they may be converted into each other but they are never created or destroyed. Since they exist now, this would imply that they have always existed and didn’t need a creator. On the other hand, according to quantum mechanics matter can emerge spontaneously in certain circumstances as long as the same amount of antimatter does too, because the total amount of positive energy stays the same. Again no creator is needed, so neither way supports the supposed necessity of a creator.

– If the Big Bang was caused by something outside of our universe’s space and time, it doesn’t make the cause timeless or spaceless. It might be a natural entity with its own spacetime and energy, say, another universe.

– We have never unambiguously observed a divine entity, so it is pure assertion to say it can exist outside of space and time. We have only observed the “abstract” (mathematics, logic, etc.) within the confines of a physical universe as it affects the objects in that universe, so we don’t know whether the abstract can exist without the material either. Regardless, you pose a false dilemma because there is at least a third choice: an object in a different system of spacetime. And the whole thing is moot until the necessity of a cause is established.

– No, the possibility of a multiverse doesn’t disprove the existence of a god, but nothing does. A god is a possibility in a multiverse as well as in a single universe. There’s just no good reason to think it’s real, let alone necessary.
