Physics in cartoons

(“Measurements of subatomic particles revealed that

they appear to be in different places at the same time.”
A well-known puzzle at the heart of Quantum physics
called ‘Superposition’.)

I generally asked my little six-year-old niece, if she knows about the Black Hole. Her reply left me stunned and embarrassed at the same time. “I know. Something that sucks in everything and does not have way out”. I was shocked. Where did she learn this? Because at her age, I barely knew what black colour was!


I know, you must be curious to know where she came to know about this. So I won’t let you wondering for much. Her answer was a surprise for all of us. “Cartoons.” I loved Shin Chan and Doraemon but I never made out anything except fun. So here in this section I’ll put across the things to contemplate because they seem too weird to be true.


We all know how the most loved character of Doraemon traveled through time to aid Nobita and save him from all problems with his gadgets much like a sorcerer. I always longed for a Time Machine. I mean, don’t we all have some embarrassing stories to obliviate! Still somewhere in my heart, I believed it to be true. May be just to suffice myself not knowing that it is true! We can actually build a Time Machine though it’s little hard. You have to surpass the speed of light to enter the past again. That sounds easy until you know the speed of light is unachievable till date.
It’s - 3×10^8 m/s. HUGE!


Shin Chan, the chirpy little kid, who never fails to make us all laugh, actually has so much to offer to a conscientious mind. If you remember in one of Shin Chan movies -- “Shin Chan: Inversion”, Shin Chan and his family were teleported to another world exactly like their’s through a short cut. While it seemed very unreal, it can true from physics perspective. Our universe is vast, very gigantic.
As Douglas Adams says, in his book ‘The Hitchhiker’s Guide to the Galaxy’, “Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s but that’s just peanuts in space.”


We humans have advanced so much but not enough to take a trip to our universe. So we can’t ever know what’s going on?  Hey remember, there’s always a solution.
In 1935, Albert Einstein associated with Nathan Rosen and speculated the existence of ‘Wormhole’ based on a special solution of the Einstein’s field equation.
So Wormhole or Einstein-Rosen bridge papers explained that a shortcut could be created between two points by distorting the spacetime to make a long distance short, which was used in Shin Chan movie to shift Shin Chan and his family to an alternate reality.


Schrödinger’s cat, a thought experiment in quantum mechanics, points to the possibility of parallel universes. What does this cat has to teach you now!?
Isn’t that what just passed your mind. Hold on. Before we start, we need to get along with these terms .
The Copenhagen interpretation is -- An expression of the meaning of quantum mechanics that was largely devised in the years 1925 to 1927 by Niels Bohr and Werner Heisenberg, no expounds that until a quantum is observed and measured it exists in a quasi state of reality. It is only our observation and measurement of quanta that causes them to condensate out of all their possible locations into a single location in time and space and take their place in our world as either matter or energy.


Now, what does this has to do with Schrodinger’s cat?
Schrodinger’s cat: A cat is penned up in a steel chamber along with the following device (which must be secured against direct interference by the cat). In a Geiger counter there is a tiny bit of radioactive substance, so small that perhaps in the course of the hour one of the atoms decays, also with equal probability, perhaps none. If it happens, the counter tube discharges and through a relay releases a hammer which shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat’s still alive if, meanwhile, no atom has decayed. The wave-function of the entire system would be expressed by the cat is alive and dead, smeared out in equal parts.

This idea was meant to show the absurdity of the Copenhagen Interpretation of quantum mechanics, especially when applied the macroscopic (everyday) world. And in an effort to make sense of this, physicist Hugh Everett came up with his Many Worlds Theory that hypothesizes that everything that can possibly happen, does happen--in a universe somewhere. Each quantum exists in every possible state in every possible location at every possible moment in time although we can only observe a single state. This supposedly makes more sense than having a cat that is neither dead or alive until it is observed.


If it’s all true, if reality does split in parts then it likely means that we don’t have free will, because every decision made by anyone--ever--will have been made by their alternate selves in an alternate universe. There must be place like ours somewhere in the far fathom of the cosmos. We just need somebody to help us travel to the alternate reality alike Mimiko Sakaru in the Shin Chan movie .
And don’t worry if you’re not intelligent and don’t like Physics, your alternate self does everything you can’t ever expect yourself to do .
