Answer: The first person with heightened sensitivity appeared 5,778 years ago; he discovered that everything comes from the upper force, and explained it. His name was Adam.
He described what he discovered in the book The Secret Angel (Raziel HaMalach). It was a small booklet of 70-80 pages, but at that time, it was considered a respectable publication.
As all Kabbalistic works, initially this book was hidden from the public and was only revealed 3,500 years ago. Practically all forces of nature were described in it but in a very difficult, essentially encrypted form.
From that time and onward, the entire methodology became revealed and each person has the opportunity to delve into it, study, and learn it.
Question: Are scientists not talking about it yet?
Answer: Scientists are increasingly incapable of understanding the world we live in. Even though our world is constantly revealing itself more and more, it is nonetheless not the type of revelation that can be comprehended by the human instruments of study. Instead, it requires a much higher order of understanding.
A paradoxical picture appears: we only uncover small, fragmented pieces of the whole of creation and build our entire science on these fragments. However, in recent times, such phenomena are being revealed that we cannot explain.
Einstein, Hugh Everett, and other scientists offered some understanding, but nonetheless, the world in which we live is becoming evermore incomprehensible.
We have no answers to the majority of questions arising today because these questions demand a completely different approach, which we do not yet possess. We cannot exist above time, space, and infinite speed, and we cannot live in a matrix other than the one in which we exist.
That is why science, that is, the potential of our knowledge, is at a dead end, but not nature itself—it is revealed in the form of dark clouds, black holes, and so on. Yet who can explain all of this? The same also applies to the micro-world.
This speaks to the fact that our cognitive tools are very limited. Science gives us what it can, being the product of our capabilities, and nothing more.
