I had just settled down at Ambili Chechi’s tea stall, sipping her legendary cardamom chai—the kind that feels like it’s brewed using quantum entanglement, because it somehow makes my neurons fire in sync with the entire cosmos—when Sukumar, the fisherman, sat down next to me and dropped the question like a stone in still water.

“Monay, what if we could go back and see who dropped the first fish into the ocean?”

I blinked. “You mean time travel?”

He nodded. “Just like your quantum theories, alle? Forward, backward… what if we could just go and see?”

And that’s when my brain began doing somersaults.

Because here’s the thing—I’ve thought about time travel before. Of course I have. Who hasn’t?

But what if—just what if—it suddenly became real. Not “in the future someday” real. I mean, “Tomorrow at 9:27 AM IST” real.

What would actually happen?

First, Let’s Rip the Fabric of Spacetime (Gently, Please)

If time travel became possible tomorrow, let’s assume it wasn’t some sci-fi DeLorean situation, but a scientifically legit, lab-certified method.

Maybe something involving closed timelike curves, like the ones proposed in Gödel’s solutions to Einstein’s equations.
(In short, he showed that time loops might be allowed in certain warped universes—Einstein was not thrilled.)

Or better yet—something born from a stable wormhole kept open with negative energy, like exotic matter.
(Theoretical stuff with weird properties—like mass that’s less than zero—needed to keep a wormhole open without it snapping shut like a clamshell.)

But the moment we could send even a single atom backward in time, we’d be throwing a Molotov cocktail into the laws of causality.

Imagine sending a particle back to yesterday. It interacts with something. That something alters a path. That path bumps into another event.

And suddenly—boom—the fruit vendor outside MG Road who always had bananas on Thursdays is now selling mangoes.
And your memory says “bananas,” but the timeline says “mangoes.”

Welcome to a paradox.

The Grandfather Paradox… and Sukumar’s Net

Everyone talks about the Grandfather Paradox.

Go back in time, stop your grandfather from meeting your grandmother, and poof—you were never born.
But if you were never born, who went back in time?

Classic paradox loop.

But Sukumar explained it better last week.

He was mending his fishing net and said,
“If you fix a hole in the net before the fish escapes, did it ever escape at all? Or did the hole know it was going to be patched?”

And that, dear reader, is the grandfather paradox in Kerala fisherman logic.

---

Alternate Timelines, Anyone?

Now, one escape hatch is the multiverse theory.

You go back and change something? No problem. You’ve simply jumped to a parallel timeline where events diverge.

Like the time Rakesh tried two versions of a codebase and kept both.
“Branching,” he said. “In Git and in life.”

So if time travel were real tomorrow, the most logical outcome might be infinite branching realities.

You go back and prevent World War II? Cool. Now you live in a reality where Hitler became a painter and Instagram influencer.
But your original timeline—yeah, that still exists. Somewhere. Possibly unreachable.

But here’s where it gets messy:
Would we be able to return to our timeline?
Or are we just tourists in endless corridors of ‘what could have been’?

That feels… lonely.

---

What Happens to Memory?

Have you ever had a moment where everything felt familiar—yet impossible?

This part keeps me up at night.

If I travel back in time and change something, will I remember the original version of reality?
Or will my brain “snap” into the new version as if it had always been that way?

That’s terrifying.

Imagine hugging your mother and feeling that it’s the first time—except it’s not.
Somewhere, deep inside, your neurons flicker with déjà vu.

Maybe that’s what déjà vu is.
Memory echoes from a version of time that didn’t fully collapse into this one.

Yeah, I know. Trippy. But plausible.

Time Tourism and the Problem of the Curious Human

Let’s say governments start regulating time travel.

Only licensed physicists allowed. Maybe you need clearance levels.
(Level 5: Visit Dinosaurs. Level 12: Witness the Big Bang. Level 20: Watch your own birth.)

But humans being humans—someone will break the rules.

There will be time-tourism companies:
“Relive the Moon Landing, Front Row Seats!”
or
“Package Deal: French Revolution and Beatles Concert, 1969.”

Time becomes a playground.

And someone will absolutely step on the wrong butterfly.
Or cough during the signing of the Magna Carta.
Or, worse, get stranded in the 14th century with an iPhone.
Good luck explaining that to a bunch of medieval peasants.

Or—my favorite—sneeze during Nehru’s “Tryst with Destiny” speech and accidentally make it sound like a joke.

Eventually, someone will do something stupid. That’s inevitable.

And once that happens…

---

The Temporal Arms Race

If country A invents time travel, countries B, C, and D will follow.

And soon, we’ll have time-wars.
Not cold wars. Cold time.

Sabotage the enemy by changing their past—erase their inventions, their revolutions, their victories.
Alter their future before it even arrives.

Countermeasures will evolve. “Chrono shields.” “Time checkpoints.”
Maybe an entire class of AI agents built just to monitor anomalies and prevent temporal edits from propagating downstream.

We won’t just have border control. We’ll have timeline control.

And that’s when I’d pack up my notebooks and move into the hills.
Or maybe into a bunker beneath Ambili Chechi’s chai stall.

Free Will, Schmree Will

Here’s the part that unravels me.

If time travel is possible, and someone from the future visits us today, then doesn’t that mean the future already happened?

Think about it.

A future person can only visit our time if that future already exists.
That implies the timeline is fixed—predetermined.

So maybe we never had free will to begin with.

Maybe every choice I thought I made—every word I write right now—was always going to happen.

That’s block universe theory, by the way.
All time exists simultaneously, like a DVD—you just perceive it frame by frame.
No rewind. No fast forward. Just… play.

But if we can go backward or forward, then doesn’t that give us agency? A way to jump out of the frame?

Unless, of course, even the decision to travel in time is also predetermined.

Aargh.

I need more chai.

Unless I already drank it tomorrow. And forgot. Or remembered before it happened. Aargh. I need more chai.

But What If Time Isn’t What We Think It Is?

Maybe time isn’t a river flowing forward.
Maybe it’s a lake. Still. Waiting.
And our consciousness just dips into it…

Each of us carving ripples—some shallow, some deep—without ever knowing how many others dip in at the same spot.
Maybe memory is just overlapping ripples.

There’s a theory by Carlo Rovelli called loop quantum gravity that suggests time might not even exist at the quantum level.
It could be emergent—like temperature.

You can’t have “temperature” with just one particle. It’s a statistical property of a group.

Imagine time not as a steady river, but as mist rising from a forest—it emerges only when enough trees are together.

What if time is like that?

No group of events—no time. Just isolated quantum happenings.

Maybe time only feels real because we observe it.

Maybe consciousness is the needle that stitches time into a narrative.

Maybe Sukumar was right:
“Some days fish are caught, and some days not.”
Not because of luck—but because timelines ripple and collapse based on who’s watching.

So What Would Actually Happen Tomorrow?

Honestly? Chaos.

Existential breakdowns. Stock market tremors. Religious rewrites. Textbook bonfires.
Philosophy departments gaining sudden relevance.
People running to meet their past selves, their lost loves, their dead relatives.

And maybe, just maybe… someone would go back and stop something truly terrible.
And in doing so, create a new kind of hope.

Or ruin everything.

We’re fragile beings, us humans. We barely manage the present.

Giving us access to the past or future?
That’s like handing over the keys to a nuclear submarine to a toddler with a juice box.

But I’ll say this:

If time travel becomes possible tomorrow, I hope the first person to use it doesn’t go to kill Hitler or visit dinosaurs.

I hope they go back to a quiet moment—a lost smile, a forgotten friendship…
a summer afternoon, the smell of mangoes, your grandfather whistling an old Kishore Kumar song from the kitchen.

---

Maybe we don’t need to rewind time. Just remember how to feel it.

---

And I hope they come back with the wisdom to cherish this present moment more fiercely than ever before.

Because maybe the real miracle isn’t time travel.

Maybe it’s the fact that we’re here—right now—in a universe mysterious enough to allow the question.

And sometimes, that’s enough.

---

If this sparked a weird little ripple in your thoughts—or made you stare out the window a bit longer today—leave a like. Or share it with a fellow wanderer in time.

You never know who’s listening.

What if it’s… you?
