Black+Holes

in 1973 John Mitchell detected that a Black Hole is strong enough to capture light and trap it there this was later backed up by other scientists.Super Blackholes that contain hundreds of thousands to billions of solar masses are believed to exist in the center of most galaxies, including our own Milky Way, as illustrated above.**
 * Nothing can escape a black hole once it has entered..** **Despite being invisible, a black hole can reveal itself through interaction with matter orbiting it. you can find where a black hole is by the way the stars arouund it move or you can see the gas that has been absorbed into the hole, this gas spirals into the black hole and gets really hot, this temperature can be detected using special telescopes that orbit space. these observations have led to the fact that black holes do exist.\
