A Train on the Rails of Eternity
What if time is just an illusion and the Universe has long since reached its end? A thought on determinism, perception, and the rails we all ride.

Have you ever wondered what the past really is? It’s something fixed, clearly defined, something that cannot be changed. And what is the future, then? It’s something undefined, something that must emerge from an unfathomable number of events. So where does the present fit in? The moment when the past is already static, and the future is not yet determined. Exactly!
So maybe time is just an interpretation of a static reality? Maybe the Universe appeared in an instant by pure chance, everything in it happened by pure chance (including our entire lives), and it simply reached its end. How do we know that the future is not yet determined? How do we know that all events - from the motion of particles to the collapse of stars - aren’t just movement along something predetermined? Like a train riding on rails.
Now imagine an experiment - there are 2 computers. On one, 10 random numbers were generated all at once, and the other can generate random numbers on demand, but no more than 10. Then an observer walks in. He approaches the first computer and presses a special button that shows him a number (the first of the 10 pre-generated ones), and he writes it down. Then he walks to the second computer and presses a button that generates a random number, and he writes that one down too. He does this 10 times.
After that, he compares the 2 lists of numbers. And what does he see? He sees that both lists look random, but in reality, the first list was generated in advance, and the second was not. Yet the observer cannot tell the difference, because both lists look random - he simply perceives the information he receives and cannot step outside the boundaries of that perception.
So is it possible that our Universe is just a pre-generated list of countless events, and we, like a train on rails, simply perceive forward motion as time?
And the scariest part is that we will never know the truth, because we are inside this system. Our perception will work the same regardless of whether everything was pre-generated or not.
There will be no conclusions, because there can’t be any.
