The Journey Begins

Thanks for joining me!

Everything has a beginning and an end. A blackhole has neither.

It’s A New Day

The Multiverse

Believe it or not, the question to existence of another species somewhere millions of light years away still blows your mind away. This is the beauty of science. I define science as the literary whose cent percent is evident, factual, unending, pure bliss. Which could never nag you, if and only if studied in its beauty, with a free and open mind. A mind open to question the existence of our specie, the reason this one in a million planet supports life. In the words of the revolutionary physicist Stephen Hawking,

“ One Of The BASIC RULES of the universe is that NOTHING IS PERFECT. PERFECTION SIMPLY DOESN’T EXIST… without imperfection, neither you nor I, WOULD EXIST

-Stephen Hawking

Stephen hawking, has been one of the top three major contributors to physics, namely Isaac Newton(IQ 190), Albert Einstein(IQ 160) and Stephen Hawking(IQ 160).

Stephen Hawking’s greatest contribution “THE THEORY OF EVERYTHING”. Stephen Hawking was able to elucidate a formulation that unified quantum mechanics and classical physics as it pertains to the description of BLACK HOLES. Breaking down what you just read and how ground-shaking this actually is, let me repeat again “BLACK HOLES”. Black holes have always been one of the most fascinating and yet the scariest myths of the universe. It is a topic over which scientists had just known about. Stephen hawking stated, proved and made it unquestionable that black holes do exist. In layman terms, hawking considers black holes these giant vortexes in space, with only one condition, VACUUM. A vortex whose main feature is wind, exists in space in form of a black hole, where there is no wind. So how are these “vortexes” formed?

An average star has a given lifetime (like our sun which has lived half its life) after which it goes through a supernova explosion(huge explosion of a star causing all its mass to concentrate in a very small radius 30-40Km causing a multifold increase in its density) leading the star to its ultimate death. After death, this star forms a neutron star(high density and small radius). According to law of gravitation, gravity is inversely proportion to the square of radius and directly proportional to its mass or density, hence as radius of the star decreases and density increases, the gravity of the star multiplies to a very high extent, hence behaving like somehow a vortex. The neutron star later forms a black hole having extreme value of gravity and the black hole is given its name because even the light nearby gets sucked by it. I think, now you can assume the assume the scale of this universal entity.

Now having said all this by hawking, it brings us to the result that “everything that comes near a black hole gets sucked into it, even light.” Now arises the question, “WHERE DOES ALL THIS STUFF GO?”

Stephen Hawking stated in his “Theory Of Everything” and his book “A Brief History Of Time”, that a blackhole actually is a two ended spectrum. Whose other end is in another universe. “wait, what?!” another universe?!

According to hawking, there are different universes, one is a parallel universe, which is a carbon copy of our universe but the exact opposite. Think of it like a mirror, your right hand becomes your left when you see a mirror.

A universe can have multiple parallel universes, the speciality being the different time zones. Every universe runs on its own clock. But is parallel at the same time, bringing possibilities of your own self few years later, or your descendents (if they survive doomsday) a million years later or maybe destruction of this universe. Who knows what time has set in our path. The time taken to travel to our nearest galaxy would be 749 million years, that too if we travel at the speed of light and the time taken to reach the edge of this universe will take 300400 times of this time i.e. 225 trillion years at the speed of light.

The Multiverse

Thinking of the Multiverse as a case of probability, the observable universe extends upto 225 trillion years creating the possibility that if you look far enough towards the end of this universe or even another universe will find you your own self infinite number of times, where some of them will be doing the same thing you are right now and others may have made different life choices and look the same but doing something different. Now marvel reference, most of you know about doctor strange, the scene where he uses the time stone to see all the probabilities of them defeating thanos. He does so by looking at the one million versions of him fighting thanos in all parallel universes. Now what I’m discussing might interest some and might as well confuse some to death.

Don’t take this too hard and understand the beauty and entirety of this eternal unending landscape of space all over.
