You may have sometimes puzzled into what is universe, what it is made of, how long is it, Which is the most complex part of our universe, but don’t worry you aren’t alone who have puzzled on this question. According to one of the famous Transformers franchise it is said that “There are mysteries to the universe we were never meant to solve, but who we are, and why we are here are not among them”. That’s too deep really too deep.I would try my best to explain you from my side.
So, what do you think is the most complex object in this colossally vast universe?
Is it the stars? you know, the fiery monsters of gas that burn hydrogen in a nuclear furnace deep inside their bellies, and emit enough energy to light up entire solar systems?

Is it perhaps the blackholes? the most mysterious and enigmatic entities in the whole universe that are so powerful that even light can’t escape their gravity. In their hearts, they hide a singularity – a point where all the laws of physics break down!

Or is it the quasars? the cosmic giants that reside at the very edge of the universe and are 1000 times brighter than that brightest galaxies. A supermassive blackhole at their core which swallows up stars and dust from nearby galaxies eventually heating up and spewing out trillions of tons of raw energy into the universe!

But, sorry to be the bearer of bad news.
My dear ladies and gentleman
the award for the most complex entity in the entire known universe goes to –

THE HUMAN BRAIN

The most renowned physicist of our time, Michio Kaku puts it like this –
“The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.”
We have unraveled the secrets of space. We have conquered mountains and oceans. We have discovered laws of physics to such a degree of precision that we can now send an un-maned spaceship in Space.But when it comes to understanding the working of human brain, we know embarrassingly little. The complexity of billions of neurons working in sync giving rise to complex phenomenon like thoughts and feelings and dreams and consciousness – is just mind numbingly impossible to grasp!
In fact, stars, blackholes and quasars are not that difficult to understand at all. We have, in principle, discovered the entire set of equations governing them. We understand these complex objects to a surprising degree of depth and accuracy. And when I say “we”, I mean the ‘human brain’. Think about it. It was actually the human brain that made all these discoveries!
Isn’t it so obvious now?
Phew! 46 billion light years containing zillions of cosmic entities, and the most complex of them all turns out to be a 1450 cubic centimeter box found on a tiny blue-colored planet in a remote corner of the universe!
