1. The Prestigious University
A physics class is talking at a prestigious university in 2054. A young professor, Dr. Nathan Holdenfield is explaining to his class the problems of
the celluloid cinema cult classic,
Back To The Future.
"I like using this movie because backwards time travel is impossible. We can go forward through high velocity dilation, but we can never reverse the
clock of the universe. I know this because if time travel were ever discovered, at any point in our assumed linear future, they would have come back
to the era of technological emergence by now. Even if it's 125,000 years in the future, had they figured it out then, they would have screwed
something up here by now."
A student near the back yells, "What about the Mandela effect?"
The class chuckles, another says, "The theology department's across campus".
"Why would we have memory of the alternate? Mandela effect assumes a deterministic X- Y timeline shift, I doubt we would have a nagging memory of
things being different. It would change instantaneously and we wouldn't even notice. We just become the person in that timeline. Like nothing
happened.
A student responds, "I disagree, the timeline shift wouldnt change the physical synapses that retain memory, theoretically. It wouldn't just
shift."
"Your thinking is rooted in a deterministic frame, Sandra," another student responded.
"I agree, I don't think we would notice, and the next time you make that point I will say it again," continued the agitated and dissenting student.
"And now you know why I like this topic. It creates a good debate. Let's discuss all these paradoxes that could occur the rest of class, and then pick
it up next", responded the professor.
It was 3:00 PM soon after and class was dismissed at the prestigious university.
2. The Ice Base
At a facility somewhere undisclosed, a scientist that doesn't exist is speaking.
"In 2016 on an ice sheet in Antarctica a balloon name ANITA made a startling discovery about the extra noise in their data. They discovered there
were high-energy particles shooting out from the ice. They tried to explain it away, a low energy neutrino can pass through the earth, but these
particle suspected as higher energy tau neutrinos, forced a crazy conclusion. This particle is too large to go through earth in that state, so it must
be either changing its state, or flowing in reverse.
Others said structures within the ice were reflecting back and it was in their heads. We disagreed and studied it.
We have run with it since that point.
Ladies and gentlemen, welcome to the South Pole. The facility you are now in, and were prevented from knowing its exact location, lies underneath the
ice sheet somewhere in Anartica. Consider your blackout lifted.
Using a high energy fusion reaction we can create and harness Tau Neutrinos. The neutrinos are directed into this mobius tube where they collect. The
mobius tube is humorously a capacitor for temporal flux. These particles create a field that flows in reverse, is dominated by antimatter, but moves
within the same frame as our own. Once the desired critical point is reached, energy is released, and the resulting burst transports the pod to a
predetermined distance into the past.
We have a time machine."
Someone in the crowd chirped, "Fitting it actually requires a flux capacitor. Sounds like something a hack science fiction writer would write."
The group laughed, and the scientist continued.
"Though selective, minimal testing using small animals we have learned the fears of the butterfly flapping its wings were overblown. Mice, reptiles,
and birds, sending any of them back, never altered present events.
We then moved on to human missions. Since that point, we have been all over our past with discretion and have yet to change anything in the present.
We are still here. We are still conducting our research.
We have learned much about indeterminism and the statistical way our world operates."
The scientist continued on wowing the new arrivals to the project. Still awed at the time travel facility in Antarctica.
3. The Humid Community College
The day after next was warm at the community college campus. Warm for fall with a sticky humidity in the air. The young teacher, Nathaniel
Hallenfeld, decided to continue the discussion from the previous class, expanding on his thoughts on time travel.
"Lets assume you can go back. What if concurrently to our talk right now, a team of scientists at a secret base is using some time portal to go back
into the past? If they changed some deterministic thing related to our ancestors, would we cease to exist? The Grandfather Paradox. This is why I like
using the ancient cult classic
The Butterfly Effect. We would change our world, but would we even notice it? What if someone just stopped
existing? Like a person in our class. Would anyone notice them missing?"
The student from a few days before reiterated her point, "I still disagree, the timeline shift couldnt change the physical synapses that retain
memory, you couldn't just swap in a new set of memories and not notice. I remember making this point a few days ago. My memory couldn't be swapped to
a scenario where I'm in a completely different situation without memory of the transition or previous situation."
No one said anything, but the teacher was smiling. "Have you heard of the many worlds interpretation? Theoretically, we are constantly making choices
that split our trajectory into tangent universes where we made that decision. Every decision into a new universe. Infinite and contained within a
single plane of possible outcomes within string theory. If that's true, we do nothing but split our universes endlessly. An endless juxtaposition
between two universal states to draw reference to. It's happening at every moment. Yet, we don't notice a thing. Even with the insane number of
universes created."
After some more lively nerd discussion, the teacher said, "Sorry to cut the theoretical fun short, but we have to do actual work on scalar fields
today."
The class groaned and got back to work at the humid community college campus.
4. The Desert Facility
At the experiment, a Colonel is talking to a Captain after a recent reactor scare.
"This is why we house this experiment in Nevada. The radiation is out of the way, and things that could go wrong are confined within a mountain. They
suggested building it in Antarctica, but treaties and other uninformed countries were cause for concern.
This is awesome, though. There is almost no time travel paradox. We can even interact and establish identities in the past without creating paradox.
Of course, we keep people away from any possible grandfather killings, but you have to really meddle in your own past to looper your existence.
We have been going strong, doing our thing, and as far as we can tell, we haven't changed a thing."
The End.
