And the man who named these mysterious places (or absence of space) is no more. John Archibald Wheeler is his name. He has spent his time with greats like Niels Bohr, Albert Einstein, and DeWitt. And his students include Richard Feynman, Jacob Bekenstein, and Huge Everett. Most of know about Feynman (for his lectures). Bekenstein proposed that a black hole's event horizon is a measure of entropy. Stephen Hawking is said to have discovered the fact that black holes radiate, led by Bekenstein's thinking. And Huge Everett proposed the idea of 'many worlds' interpretation in Quantum Mechanics. (Wikipedia says he left physics as he found that other physicists didn't accept his theories. However, he managed to become a millionaire, being a defense analyst and consultant.)
Back to Wheeler's story, he was the pioneer who sought to combine gravity and quantum mechanics, leading to the development of the field called Quantum Gravity. He was awarded the Wolf Prize in Physics in the year 1996-97.
And it's one more obituary in this column. We've lost another great mind.
