Unveiling the Secrets of the Empty Space in the Universe
The vacuum of space is not truly empty. While the density of interstellar space is extremely low, it still contains charged particles, hydrogen atoms, and dust. Even in the cosmic voids, the emptiest regions of the universe, there are lightweight particles called neutrinos and the cosmic microwave background radiation. Additionally, quantum fields give rise to particles and have an intrinsic energy known as vacuum energy. So, even if one were to nullify the vacuum energy, they would still be surrounded by space itself, which may have its own existence. The question of whether true nothingness can exist remains unanswered.
