The description you provide seems to invoke a poetic and metaphorical view of the universe, where concepts from physics and metaphysics blend together. It's important to note that the response to your question will heavily depend on the philosophical or religious perspective one adopts.
From a scientific standpoint, singularities are points of infinite density and curvature that arise in certain physical theories, such as in black holes within the framework of general relativity. The nature of singularities is still not fully understood, and our current understanding breaks down at these points. It is unclear whether singularities serve as gateways to any transcendent or divine realms.
On the other hand, the concept of the divine Essence or Atzmus is rooted in theological or philosophical frameworks and often falls outside the realm of scientific discourse. It pertains to ideas about the nature of ultimate reality, the divine, or a transcendent realm that is beyond empirical observation or scientific investigation.
Therefore, whether every singularity could be seen as a gateway to the divine Essence depends on one's personal beliefs, philosophical outlook, or religious perspective. It is a matter of individual interpretation and not something that can be addressed solely through scientific inquiry.
