What do you think lies at the edge of universe?
Perhaps you think there is more… universe? Then let me rephrase my question. What do you think is at the edge of everything that exists?
Ah, now we’re talking.
You may answer “nothing.” But that doesn’t sound quite right… What then happens if one were to reach the edge of everything? They would hit an invisible wall? Or keep “advancing” at the same spot as if they walked straight into Zeno’s Dichotomy Paradox. Perhaps they would just seamlessly loop around to the other end of everything? But again, that doesn’t sound quite right.
But maybe you find this question misplaced to begin with. After all, “everything” doesn’t have an end, you may argue. And that would be precisely my position. How do I know that? You ask? Well I don’t. But here is why I believe it:
Think of two points in space. A and B. But separated by… nothing. That’s right, in this setup, imagine there is nothing between them. Wouldn’t that imply that there is also no space? Then aren’t they touching?
Again, think of two points in time. Point A and point B. Imagine there is nothing between those two points. Wouldn’t that mean that there is no time between them, and that thus… they are touching?
In fact, there is an infinity of nothings between any and all points in space and time, even at the so called “edge” of the universe. If truly there is nothing there, surely it is touching something, and thus must continue, necessarily into infinity. This may not be true, but makes the strongest intuitive sense to me when attempting to conceptualize of nothing.
But if the universe is infinite… if everything is infinite… even time… then my brain is so screwed lmao ![]()
I will be honest with you, it breaks my brain. But I believe it doesn’t only break my brain. It would also breaks… reality itself. Let me explain.
First, consider this:
P1: Any event with a probability of occurrence different from 0 will eventually happen if given infinite time (let’s refer to such an event as a possible event).
P2: Time is infinite into the future.
C1: All possible events in the universe will happen infinitely.
Now flip it:
P1: Any event with a probability of occurrence different from 0 will eventually happen if given infinite time (let’s refer to such an event as a possible event).
P2: Time is infinite into the the past.
C1: All possible events in the universe have happened infinitely.
Now bring it together:
P1: Any event with a probability of occurrence different from 0 will eventually happen if given infinite time (let’s refer to such an event as a possible event).
P2: Time is infinite into the the past and the future.
C1: All possible events in the universe have happened infinitely and will happen infinitely.
Of course, only if time is actually infinite. But if we approach it as per my intuitive reasoning above, then it may be. For the sake of argument, let’s suppose that time is in fact infinite on both ends (I would argue that so is space as well, it’d have to be but that’s not the point).
Next, picture an infinite flat line. Where is the center? That’s right. there is no center. From any given point on this line, the distance to the edge of the line is undefined, since the edge doesn’t exist. This means that no single point has an objective position on this line. Again, at best, we can locate a given point in relation to another. But that’s about it.
If this line corresponds to time, and a point on this line corresponds to a possible event, how could we differentiate between that event an another? Well, easy. We could compare their relative position on the timeline. If we looked at the entire timeline though, none of them would ever come first, since it is infinite. So we would compare them by taking a chunk of the timeline where there is a start and an end.
Now let’s say we wanted to differentiate between the same event (event A), but two different occurrences of it. If we simply looked at the events, there would be no way to tell the difference, since they are the exact same. Thus, we need some context, which will roughly look like sampling one or more points / events (event B) around the happening of the events we would like to differentiate.
For example, if let’s say our event of interest is a hyper specific version of me who is emo, eating ice cream at a very specific spot on top of mount Fuji (That’s event A. I know… wtf…). Well that event may happen exactly that way earlier on the timeline and later on the timeline, without those two chunks of the time line being identical. Perhaps in one of those occurrences a planet at the other end of the galaxy has one less rock than in the other (variation of event B). Those two events together (event A and B.1 / B.2) can allow us to differentiate between two identical event As on the timeline. That is our context.
But here is the kicker guys… The combination of event A and B.1 being a possible event, also repeats infinitely on the timeline. If we wanted to differentiate between two occurrences of event A+B.1, we would need to sample more context through variations of an event C.
I am sure you see the pattern… This new context including variations of event C also happens infinitely on the timeline. Essentially, it never ends.
What does this mean?
It means that if time were to be infinite, no two occurrences of a possible events would be virtually differentiable from one another. In other words, whether something happened in the past, the present, or the future is virtually the same… ready? AS IF TIME WASN’T A THING Any given event just is at the scale of this whole infinite timeline. It would thus seem that infinite time takes on the property of no time… A perfectly static universe where all possible events are just sitting there ever happening.
ISN’T IT MIND BLOWING!? ![]()
To clarify, time as we understand it would still exist in any non-infinite chunk of the timeline. It is precisely the existence of time that seems to entail its non existence. The above conclusion only works when looking at infinity or the whole timeline.
DISCLAIMER: Even though it is my current philosophical position, this post serves the purpose of fueling thoughts and engaging with interesting ideas. I just love philosophy and thinking. I am not trying to prove anything and my conclusion could very well be wrong. But I am excited to hear you guys’ thoughts.
