Have you ever wondered whether time travel could ever become a reality? The entire scientific community seems divided on the topic. Some say maybe, others say maybe not, and a few even say yes, but they ruin the fun by clarifying that it would only work in the forward direction. Here's a little story I want to share that might give you some food for thought about time travel and the paradoxes it could create.

Imagine this: You’re a kid, and it’s Christmas morning. You wake up to find a mysterious and futuristic gift (let’s say an advanced drone) in your bedroom. You’re excited but also confused because it doesn’t look like something your parents would get you. When you ask them about it, they’re just as comfused as you. In fact they already have a boring gift box of books and games prepared for you, so they have no idea where this strange drone came from. Unsure of what to do with it, you decide to keep it for later—maybe Santa intended for you to use it when you're older.

Fast forward 30 years, and time travel has become a reality. you’re very excited and thrilled and decide to give it a try. As you plan your first trip, a brilliant idea strikes—you will visit your younger self on Christmas morning and leave them a cool gift. But what to give? Then it hits you—you’ll leave them the very same mysterious drone you received as a child.

You travel back in time and, without waking your younger self, you sneak into the bedroom and place the drone there. Mission accomplished, you return to your own time. But then it dawns on you: the drone you received as a child was the same drone you just gifted to yourself. The gift has no origin—it exists because you gave it to yourself in a time loop.

It’s a weird and confusing thought. This kind of paradox is one of the reasons time travel might never be possible. If something like this could happen, how would it even make sense? An object (the drone) exists, but its origin is a mystery—it seems to exist only because of the time loop. Idea of time travel are full of paradoxes like this one, making the idea very complex. Sometimes these paradoxes make me wonder if time travel will ever truly be possible. But then scientists like Michio Kaku argue that the concept isn’t entirely hypothetical anymore.

What is your opinion? Do you think time travel could ever happen? how could we resolve paradoxes like this if it can happen? Could theories about parallel universes or alternate timelines hold the key?
