When a Black Hole is Our Brightest Star | A Personal Note from Arnold Leitner, Founder
I have been a scientist once. I studied superconducting films at ultra-low temperatures below 500 millikelvins.
If you want to know why, please watch the documentary “The Edge of All We Know,” which documents the incredible achievement of imaging a black hole at the center of a giant elliptical galaxy called Messier 87. This 2020 documentary is now streaming on Netflix, but you can find it on other platforms.
