A concept of time, infinity and time travel

Let’s not talk art for a moment. Or better said, lets talk about the ultimate art.

People often ask why, if time travel is possible, we do not see evidence of people travelling back from the future. I believe the answer lies in the nature of infinity.

If infinity truly exists, then it is difficult to imagine that it applies only to numbers or space. Infinity would also imply infinite possibilities, infinite timelines, infinite histories, and infinite futures. Every possible choice, every possible event, and every possible outcome would exist somewhere within this infinite structure.

Among these countless timelines, there is one that matters to us: the one we are currently experiencing. We perceive it as “our” history because it is the sequence of events through which our consciousness is travelling.

This offers a possible explanation for the apparent absence of time travellers.

Suppose time travel is eventually invented. The common assumption is that someone would return to the past, change history, and we would notice those changes. But perhaps that is not how reality works.

The moment someone travels through time, they do not rewrite their own history. Instead, they enter another already-existing timeline—one in which their arrival was always part of that reality. Their original timeline continues unchanged. Likewise, the timeline they enter continues according to its own history.

From our perspective, nothing changes because we remain on the timeline we have always occupied. The traveller has simply left it.

In this sense, time travel both exists and does not exist.

It exists because movement between timelines is possible.

It does not exist, from our perspective, because it never alters the history we remember. Every timeline remains internally consistent.

The same reasoning applies to seeing the future.

If someone were somehow able to observe the future, they would not be observing the inevitable future of their current timeline. Instead, they would be observing one of the infinitely many possible futures. The very act of reaching or observing it would place them on that particular path.

Likewise, travelling into the past would not allow someone to change their own past. They would simply become part of another timeline in which those events unfold with their presence included.

History is therefore never rewritten. It is only experienced differently.

This also changes how I think about premonitions.

I do not believe premonitions are examples of travelling into the future. Instead, I think human beings are constantly collecting extraordinary amounts of information, much of it unconsciously. Our brains recognise patterns far beyond our conscious awareness. Sometimes what we call a “premonition” may simply be our minds decoding these patterns so accurately that we correctly predict what is about to happen. We are not seeing the future; we are calculating it without realising we are doing so.

Ultimately, I believe every possible pathway already exists.

Every choice, every consequence, and every version of events forms part of an infinite structure. We do not create new realities by making choices. Instead, our choices determine which pathway our experience follows through this infinite landscape.

So, do I believe in time travel?

Yes.

I believe it is entirely possible that it exists somewhere within the infinite possibilities of reality.

But do I believe it can change history?

No.

History is never rewritten. A traveller simply leaves one timeline and continues their journey along another. Every timeline remains complete and internally consistent, and each observer experiences only the path they occupy.
