The term black hole was coined in 1969 by the American scientist John Wheeler as a graphic description of an idea that goes back at least two hundred years, to a time where there were two theories about light.
The black holes in our universe may seem like bizarre, voracious beasts – but stranger ones are possible. Simulations of black holes have revealed the first superfluid specimen.
Superfluids are a form of matter that take mere melting one step further. When a solid turns to a liquid, what was once sturdy and inflexible begins to flow. Superfluids have zero stickiness or viscosity: they can even flow uphill. They also have completely uniform temperature.
Well some truth here there is no black holes because there is no space this was made up by NASA and the LIE about EVERYTHING, also the earth is flat and we are under a dome. We never been to the moon RESEARCH FLAT EARTH!!!!
