# How powerful is the Universe?

Have you ever wondered just how much energy and power could have all the stars in our universe put up together? I have always been passionate about astronomy, even though i cannot become like the astronomers , but i can just pretend to be one. In the last months the documentaries i watched, gave me pretty much the idea that the universe is too big to be comprehended in numbers, as it is going to blow our minds off. To take an example, a star could be 10x1000000000000000000000 (1)solar masses, or a star could have energy to light up an entire galaxy, if it would to explode in this instance. But what about galaxies (2)bilions of light years away from our planet producing rays of light or energy, equivalent to all stars in the universe put together. That's what we would call a monster, a super dense (3)black hole, in a center of a super dense galaxy. These galaxies are the most dangerous in our universe the scientists say, and they are called Quasars (search more on the net). The scientists also state that, Quasars can "feed" on other galaxies, by atracting them first with their super gravitational pull, and afterwards collide with them and "spitting" matter outside after it got sucked in. The process of "feeding" on one star could take a 100 milion years. So here you have it, the most powerful force in the universe followed by many other dangerous (and mysterious in the same time) types of stars/galaxies, that could shred our planet to pieces in miliseconds. I , for instance, am happy that i could see a small piece of this universe, and know that we surely aren't the smallest, but nor the biggest (as a majority of people would say) and we surely can't comprehend the energy amount or power, of this beautiful and dangerous Universe we all live in. I hope you enjoyed my small and insignificant article of mine. I hope you all have a great day!

Mini dictionary:

1. the solar mass- (M☉), , is a standard way to express mass in astronomy, used to describe the masses of other stars and galaxies. It is equal to the mass of the Sun, about two nonillion kilograms or about 332,950 times the mass of the Earth or 1,048 times the mass of Jupiter

2. light years- 1 light year is equal to 10 trilion kilometers or exactly 9,460,730,472,580.8 kilometers

3. black hole- According to the general theory of relativity, a black hole is a region of space from which nothing, including light, can escape. It is the result of the deformation of spacetime caused by a very compact mass
