The Multiverse Theory || Do parallel universes exist? ||
This is earth. Where you , your loved ones and other animal species like birds and different animals lives together. We are one of the nine billions or more species.
Viewed zoologically, we humans are Homo sapiens. we humans from being struggling to survive to hunting and gathering to farming, now rule on earth ! The process was much longer! But now we are intelligent enough to study about our own planet to stars and other planets in other galaxies to black hole ! We have been trying to find answers to our own risen questions! One such question is - do we matter? Do we really matter?
So to answer that, we need to go up high, really very very high! So let's know how very small we are! And how we do not matter to universe!
Let's start from our home planet , earth. We have been living here for around two million years ago, and in these millions of years , we have been through a long process of development. The process of development include first telescope to first steps on moon! It took almost 361 years to step on moon after inventing our very first telescope by Galileo! Now we are sending different mission's to our solar system, to study it. Many space telescopes such as Hubble space telescope played important role in our adventurous journey to space!
Through these telescopes we opened our doors for our curiosity! We looked up really high. We saw our solar system, other galaxies and planets to alot more!
Solar system! When we hear the name solar system, an image of a host star and eight planets , including our own and their natural satellite. But there's a lot more here. Our solar system has a diameter of 79 AU. Whole one AU = 15 million km. And in this vast system , we have done many mysterious and interesting discoveries! Thinking that we know everything about our solar system is ridiculouse! We know almost nothing !
There are many theories about our solar system like nemesis theory which states a companion star of our sun and planet ninth theory! Our solar system is one of the billions and trillions of star systems present! Way more mysterious and strong candidates to sustain lives! Our solar system is present in milky way galaxy. It is an average size galaxy with billions of stars it. Milky way galaxy has a supermassive black hole in its core named Sagittarius a star.
The supermassive black hole is almost 17 times that of the Sun, meaning that it would sit well within Mercury's orbit. The Milky Way is a barred spiral galaxy around 13.6 billion years old with large pivoting arms stretching out across the cosmos. Its disk is about 100,000 light-years and just 1000 light-years thick
Our milky way is just one of the galaxy in our local group which has almost 30 such galaxies. One of them is Andromeda galaxy which is going in a collision path with milky way in few billions of years.
Our local group is part of Virgo supercluster, which spread over 55 million light years! This is overpoweringly vast! Feel small yet? But wait there's more! The Virgo Supercluster is one of about 10 million superclusters in the observable universe and is in the Pisces–Cetus Supercluster Complex, a galaxy filament.
Laniekia supercluster is the one in which Virgo supercluster is located! It is unimaginably big! With every seconds of time passes, our universe is expanding!
Not only expanding , but the speed of expansion is increasing and is more than speed of light!
We are nothing, literally nothing! This universe of ours is unimaginably vast! Earth in this universe would exist or not, no one would barely even care!
At some extent , the problems which cause people depressed are of no meaning. All those problems are seem to be pointless. Live your life as you wish. Cause you live or die, no one would even care. But what matters is how you live your life!
If you want to do painting , many people are doing it right now! If you want to do something great for aphumanity there are many people again doing that. Just live your life happily.
Thank you for watching!
have a great day ahead! 😁✨✨
