–Vindication of Einstein 100+ Year Old Prediction–
Big or small in size, a black hole is a super massive anomaly in the fabric of space, often likened to worm holes or conduits between space time. Black holes can be as small as just one atom, with the mass of a large mountain; or it could be much larger with the equivalent mass of many suns squeezed into the volume of a large ball. Very strange this black hole stuff! So strange that the gravitational field left over from the collapse of multiple stars [supernovae] is strong enough that not even light can escape its grip….thus it appears black, and hence the name black hole.
Predicted more than 100 years ago by Einstein while formulating his theories on relativity, documented photographic evidence of a black hole has now confirmed its existence. The target for this actual observation using the Event Horizon Telescope was a giant elliptical galaxy known as M-87, about 55 million light years away in the constellation Virgo; a black hole that contains six-and-a-half billion solar masses crammed into a region about the size of a solar system. Check it out!
The globe-spanning network of radio dishes, atomic clocks and computers making up the Event Horizon Telescope also is expected to image Sagittarius A*, the supermassive black hole at the heart of our own Milky Way galaxy; which is a more “tame”, less massive version of the M-87 black hole. Our galaxy’s anomaly is a 4.3-million-solar-mass black hole filling a volume smaller than Earth’s solar system, located 26,000 light years away in the core of the Milky Way. Its presence can be observed in the motions of nearby stars. Those motions at the core of the galaxy have been studied for years, providing the mass of the hole along with other insights, but no one has actually viewed the black hole itself. It may be photographed soon!

Thomas Edison was interested in space too, trying to measure the temperature of the sun during a solar eclipse. He also understood the radio emission of stars. Check it out at a previous blog published on this website: edisonmuckers.org/radio-astronomy.
