I love the correlation between Hawking radiation and, a term new to me, Unruh radiation. That math is beyond me, but I can certainly appreciate it’s revelations. I am inspired that humanity has learned enough to determine that the universe is unlimited in size, but realize our ability to experience it is limited by the nature of the universe itself.
And, not stated in the article but implicit in the logic, is a belief central to my worldview. Just as our Sun is not unique in the endless Sea of stars, our Big Bang is not unique in the endless progression of Time.
