How much of today's science derives from Kabbalah and the occult?

I do not know the percentage, but the Kabbalah plays a part at least in Jewish science, and it has an affinity for conclusions like the multiverse and the Big Bang. With the Big Bang, the real question is where the Big Bang came from, so they just move the problem back a step to the multiverse, and then where did the multiverse come from; they can never answer it. That is Kabbalistic thinking: you make up things to fill your metaphysical gaps, and you bring in the mystical and the occult. This is nothing new; the Greek mystery religions did the same, and those devotees took drugs, some form of lysergic acid or mushrooms, which put them on a different plane, and then they wrote down their notions of where the world came from, and the Kabbalists did likewise. The first scientists of the Enlightenment were alchemists, and alchemy is an occult science; Galileo made his money as an astrologer casting horoscopes. Here is the point: if you do not have the truth, which comes from Scripture and what the Church dogmatizes, you do not know where to start, whether the earth is in the center or off in the recesses of space. But with Scripture we do know where to start: the earth is in the center, and that is an absolute truth.
