Eminent physicist John Archibald Wheeler has died from pneumonia at the age of 96. The coiner of the terms ‘black hole’ and ‘wormhole,’ Wheeler popularized the study of general relativity.
Theoretical physicist John Archibald Wheeler died of pneumonia at his residence in Hightstown, New Jersey yesterday. Wheeler is most known in the popular culture for popularizing the term “black hole” to describe stars which had become so dense that nothing, not even light, could escape their gravitational pull. Although Wheeler initially objected to the idea, he later accepted the idea and coined the term “black hole” to describe such objects.
RIP and condolences to the family.

The Universe is defined as the summation of all particles and energy that exist and the space-time in which all events occur. Very little is known about the size of the universe. It may be trillions of light years across, or even infinite in size.
Now we found the hole is nearly a billion light-years across. It is not a black hole, which is a small sphere of densely packed matter. Rather, this one is mostly devoid of stars, gas and other normal matter, and it’s also strangely empty of the mysterious “dark matter” that permeates the cosmos. Other space voids have been found before, but nothing on this scale.
