Not every idea that anyone gets about some verse in Torah counts as Torah. Not only that, but sometimes the effect is even negative. Rav Nahman of Breslov himself brings this idea that it is forbidden to listen of even to hear the Torah lessons of a wicked person.
To get some clarity about this, I learned the Mishna in Sanhedrin about "outside books" that are forbidden to learn. I discovered that the Rif and Rosh explain what are "outside books"? Books that explain verses of the Torah, but not based on a midrash Chazal. That is, they explain the verses in some way not like the sages of the Mishna and Gemara explained them. This would include the vast majority of books today that claim to be ''Torah books.'' But in fact, we see from the Rif and Rosh that they are "outside books."
[So natural science books are not "outside books". ]
