But that is not the only surprise.
People began to realize that these tiny star-like things or they looked like stars are actually putting out as much energy as a hundred of galaxies 1. And they didn’t look like a galaxy 2 at all.
The paradox 3 was how something so small could be so bright. What could possibly produce such a mind-boggling source of power with some of them pumping out more energy than a trillion suns? They were given the name quasars.
Quasars became a very big and deep mystery because they were distant in the universe therefore we were seeing universe as it was billions of years ago. And they were more potent 4, more luminous 5 than anything else that we’d come across before. Solving that mystery turned out to be the crucial step on the journey that would eventually lead to our observing the strange behaviour of our own feeding black hole. What was first needed was a math reckon cite from one of modern science’s truly original thinkers.
I was thinking about that mystery that’s absolutely true. And there were a number of different ideas that were put forward but none of them was terribly convincing.
