Paradox

**************************************************************************************

Scientist 1: So you are telling me time travel is possible.

Scientist 2: Indeed.

Scientist 1: And all these while, we did not have any idea how to make that possible.

Scientist 2: As a matter of fact, we always did. We always had it right in front of us but we could never see it.

Scientist 1: I am skeptical. All these while we knew about it still couldn’t travel in time?

Scientist 2: That’s true. In fact, a lot of us did, without even knowing.

Scientist 1: I’m confused. I am really confused.

Scientist 2: About what?

Scientist 1: Alright say we have a time machine. Say as you have claimed probably you have invented the time machine. But what about the basic questions and paradoxes about time travel?

Scientist 2: What about them?

Scientist 1: What about ‘Grandfather Paradox, Bootstrap Paradox or Butterfly effect? How can you avoid them while traveling in time? Or are you going to throw the multiverse theory at me?

Scientist 2: Naah, they can be explained without creating multiple universes as their after effect.

Scientist 1: I am eager to know.

Scientist 2: Alright, let’s take the Grandfather Paradox as an example.

Say someone travels back in time and kills his grandfather before he even met his grandmother. Obviously, that means deleting his family tree from his grandfather and then the time traveler cannot exist and that’s impossible because he just went back in time from the present and he exists in the present. Hence a time travel when travel in time will not and must not have the power to change the course of history. Now it is quite naïve to expect some divine power will stop him from doing so.

In that case, the most likely proposed theory is the time traveler will be invisible. He will be a mute spectator and not only that, while he is there in the past, nobody will be able to see him. To make things simple, a time traveler’s conscience, his mind will travel back in time, not his body. So he will be witnessing everything but will not have the power to change anything, at the same time because he will be invisible to all the people in the past, he won’t come across in any harm’s way.

Scientist 1: Let’s say we accept this theory, but then that will bring us to the Bootstrap paradox. What if a famous movie director yet to be famous in time decided to travel in future. There he came to know he will make a movie in another 5 years which will make him famous worldwide. He watched the movie in future, came back in present and made the exact copy of it. So basically the original screenplay, plot and the movie is actually a copied version from the future.

Scientist 2: Yes, that just can’t happen. You cannot create the original by copying from one of copied piece from the future. That paradox has only one solution. The time traveler shouldn’t remember any detail of his travel, because if he remembers any of that can change the course of the history or future. So as he will be traveling in past or future, once he will come back he won’t remember any events.

Scientist 1: What if someone travels with a camera or portable recording device?

Scientist 2: Technically it is not possible, I believe that will not work either, first of all, the person will travel without a body, only his mind. And if he could possibly take it also, the electromagnetic field that will be created while traveling will damage any electronic goods.

Scientist 1: So the points we got from here are

• A person can only travel in time without his mortal body, just his mind and he can only see but possess no power to meddle with anything.
• Once he is back in presence his memory will not be able to remember anything he saw.
• He cannot record anything either.

Then what is the whole point of traveling into time? It’s useless then.

 

Scientist 2: If only you think of conventional time travel that feeds into our minds for centuries then yes! But the truth is, people have already traveled in time.

Scientist 1: When and how?

Scientist 2: Time dilation, as described in the theory of relativity. The time moves slower than earth in space, due to the gravitational force, the earth’s rotation on its own axis and also for orbiting around the sun. Every astronaut who traveled in space starting from Yuri Gagarin, they all came back to earth a little younger.

Scientist 1: So………………

Scientist 2: Longer you travel in the space, slower the time moves. And then when you come back to earth, you see you are ahead of your time, or perhaps behind it.

Scientist 1: I don’t know what to say!

Scientist 2: Time travel is a one-way ticket, my friend. Once you travel in it, there is no way to go back and forth.

Scientist 1: We were never formally introduced.

Scientist 2: You can call me an alien, as I left the earth 500 years ago.

Scientist 1: …………………..

Scientist 2: have you ever thought about it? The people you call alien or higher intelligent being, what if they are the human who returned…. !!!

Landlord & Tenant

 

*“Ahh, early morning and your divine presence, Good Morning Sir.”

**“Heh heh, how are you doing? On such a fine Sunday morning, I just couldn’t help but come down and say hello to you.”

*“Of course, of course, please come in. So like to have some tea, coffee? Coco?”

**“No, no, I am good. I was hesitant to disturb you, you know after all you are such a renowned scientist, must be always busy. It’s my wife who is keep nagging me to check on you, being so busy I am sure you forget few trivial things, so she is always worried you see.

*“I can only imagine, I guess she only called the police twice here, if I am not wrong.”

**“Heh heh, actually first time when all those unworldly sounds were coming from your kitchen…. Err.. I mean from your lab, she panicked. You know how women are, and the other time when we felt that strange smell from your backyard, we thought it might be a dead body decomposing, I mean we were sure it wasn’t a human but still. Then it turned out to be another your fancy sciency chemical invention. “

*“Of course, of course, you have been such a good landlord to me.”

**“Heh, heh, when initially the people warned me not to keep the ‘Mad Scientist’ as tenant, I told them on their face that I believe in science. So what if I have to get double the amount and increase the rent every 6 months, but I will have a scientist in my ground floor. I don’t even mind being called the ‘Mad Scientist’s greedy landlord’, I know your potential. By the way it’s already 3^rd of the month, our agreement was rent on 2^nd of the month right. See you have forgotten it again, sign of a brilliant and absent mind truly. Heh heh.”

*“Oh I do have the cash ready as always, I just wanted you to come and get it. By the by, before I pay you the rent, I would like to show some of my creations today if you would like.”

**“Really, heh, heh, sure, sure, lead the way.”

*“This way please. This is IQ meter, to measure the intelligence quotient, just wear it on your head and you’ll have your IQ test, would you like to try?

**“Haha, another day may be”

*“Sure, so here is the Nano computer spectacle, the part of the asteroid I am researching on and the invisible suit and yeah, that’s my favourite…..”

**“Oh god! It….. It looks just like me,”

*“Yes, that’s an android, made up of metals and human flesh and tissues with a computerized brain. Thought it will be the best gift for your birthday coming next week.”

**“I…. I just can’t believe my eyes, it’s of same everything of mine.”

*“Yeah, and look this way, my prized possession, my time machine.”

**“I still can’t take off my eyes from my birthday gift. Wow!”

*“Come this way sir, yes now take a seat in this chair. Isn’t it comfortable, every time traveller deserves a good seat while travelling?”

**“Woah, wait, wait, why are closing the door of this thing, time machine or whatever, I am in no mood to travel anywhere.

*“But you must sir, because of you greedy and materialistic people we scientists face all kind of harassment, named ‘Mad Scientists’ and forced to stay in this hell hole and pay double the rent. Even for minute sounds and smell of my experiment you call the cops to investigate, you truly are a disgusting creature.

You deserve a place with where you belong, 18^th century, where I am sending you precisely, don’t worry, your wife and people will not miss your presence, my android will keep them happy and satisfied, It will even grow old and die as you should have, only I have to fix the date of expiry. Are you screaming in there? No use, these glasses are soundproof hence I can’t hear you, bye bye Mr. Landlord.
