Last Wednesday was no ordinary. The event horizon team were able to engineer the first picture of a black hole. Since over a hundred 100 years, this has only been imaginary and theoretical. Not any more though.
Our planet earth has about 510.1 million square kilometres in surface area. We are part of the solar system with sun in the centre. Our sun is whopping 109 times diameter then the earth.
Our solar system is roughly 122 AU in diameter where each AU (Astronomical Unit) correspond to 150 million kilometres!
