For us, as humans, the concept of absolute nothingness is virtually incomprehensible. And to compound this and think that out of absolutely nothing came the vastness of universe and everything in it, that's simply beyond our comprehension.
Yes, exactly. Thus the incredibly complex hiddush (original idea) of creation ex-nihilo, brought by Torah Judaism. It is a very complicated idea indeed. But science runs on the assumption that there was no such thing because such a thing is a scientific impossibility. Science runs on the assumption that there was not "absolute nothingness" because there could be no such thing without a 'miracle,' and science does not operate in the realm of miracles. So they start with their assumption that there is a physical explanation and go from there. "Creation ex nihilo" (from nothing) is a complete hiddush and utterly incommensurable with the scientific point of view. They use equations to determine what caused the Big bang and what happened in the immediate aftermath. These equations are post creation. G-d's act of creation cannot have been bound by any such laws.
Physicists tell us matter can not be created or destroyed. So where then did all the matter in the universe come from ?
That's why physics can never quite get there. Physics can explain the operations of the physical world up to a certain point in time in the past, but they can never get beyond a certain hurdle because they don't accept the idea of "something from nothing." Something from nothing is a scientific absurdity. One that occurred. And we know it occurred from the Torah of Moshe Rabenu. But what reason does a physicist have to assume such a notion? So he will never be able to explain the actual creation of the world, try as he might.
These most basic quandries are why many physicists agree there is an unknowable force that transcends time and the laws of physics.
Some physicists might, but relatively speaking, I don't believe it is "many." In any case, that is a
belief they may hold, but it is not provable and therefore not scientific. Sometimes scientists share beliefs of religious Jews and vice versa. No problem with that. That doesn't turn the belief into physics necessarily.
This force is what we call G-d.
Not true. The big bang was not creation of the world because you can't pigeon-hole the creation to any particular point in history. To say it happened at time x is against the entire concept of creation ex nihilo. This is why I said that by the Rambam, it is an absurdity to point to any particular date or time and say that that is when G-d created the world. It was an action that existed/occurred outside of time. A deep understanding of the Moreh Nevuchim will help us arrive at this conclusion as my rabbi has taught me.
Our sages do not disagree with the big bang theory. Nachmonides in his Kabalistic writings states that there was only one original physical creation. This singular physical creation was about the size of a grain of mustard, and a 'substance without substance'. Nachmonides also says that it is only when matter congealed that 'time grabs a hold'. A phenomenal insight that was only confirmed thousands of years later by Einstein.
What does any of this have to do with the Big Bang? Plato also had an interesting theory about the creation of the world (different from creation ex nihilo) and HUGE authorities like the Rambam and Kuzari say that a Jew can accept the beliefs of Plato about the origin of the world and still is a kosher Jew, that it can fit with kosher Jewish belief. But ideally a Jew should believe in creation ex nihilo. Also it's implied by the Rambam that if there was a real scientific proof to Aristotle's philosophy that the world was eternal (That was only a philosophy, a popular one of the day, and convincing to many people, but no hard scientific evidence to it), if there was such proof, it's implied that we could interpret maaseh bereshith accordingly. Rambam says about this, "The gates of interpretation are always open."
But since when is the Big Bang the beginning of everything? Hawking doesn't say that. Major physicists claim that two universes folded into each other producing the big bang. They can't really prove this, but we can't base our belief in G-d on scientific theory. As we now see, to do so with the scientists' explanation of the big bang, would have been a catastrophic mistake. Because now the very same scientists who hold of the big bang premise, also believe that it occurred as a result of universes collapsing on each other.
The apparent contradictions between the Biblical 6 days of creation, the approximately 6,000 years of 'generations' after Adam and the scientific contention that the universe is billions of years old (as we humans measure time) is easily resolved with a deeper understanding of Torah.
I don't think I ever disputed that. I think the major error is to take "6 days of creation" as something literal. Without making that mistake, it's actually quite easy. (Or at least... 'much easier' to do).
