Ok, seriously, I wonder if when we die and go to heaven do we get to know how things were in history and can we see those kinda things? Like you could go back to Ancient Greece and watch the city states fight each other, or could you go see DaVinci draw his vitruvian man...

In all seriousness, I have asked myself this question more times than you can count. Sitting aside a campfire looking up at the Milky Way and thinking to myself, what's outside of this...and what's outside of that...and what's outside of that? Etc....

Sometimes, I guess, there are no answers.


Stephen Hawking remarked in his book, A Brief History in Time, “In this way, Edwin Hubble worked out the distances to nine different galaxies. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars.”

So, what’s beyond all of this?


According to our current understanding of physics, the answer to this question is "nothing."

Not "nothing" in the sense of empty space without anything in it - "nothing" in the sense that there's no "outside the universe" for anything to be in in the first place.

For this to make any sense at all, you have to understand that when physicists talk about the universe "expanding," they don't really mean space is sitting still and all the stars and stuff are shooting across it getting farther apart, they mean space itself is getting bigger.

If you picture a piece of the universe as a bunch of dots (stars) on a piece of graph paper (space), the universe expanding means that the piece of paper is getting stretched out, and the squares on the graph paper are getting bigger, not that the dots are moving across the paper (although of course, that happens too).

The other part necessary for it to make any sense at all is that, according to our current understanding, the universe doesn't have an "edge" or an "end." There are basically two possibilities, either the universe is infinite (it goes on forever, so there's no end) or it's finite, but kind of loops back on itself (so if you travel far enough in one direction, you end up back where you started).

The universe looping back on itself is impossible to visualise in 3D space, but you can do it easily by taking away a dimension. Make "the universe" be the surface of a ball. The surface doesn't have an end, and if you travel straight across the surface for one entire circumference, you end up back where you started.


But when you leave the surface of the ball, by going straight up for example, you are entering something else. So you can't just take away a dimension, that dimension is there and exists.

Kind of like how imaginary numbers can't exist based on the rules of math, but if they don't exist whole disciplines of math dont work.

Maybe, we just don't really understand a damn thing after all.

It's commonly believed amongst physics nerds that the 4 commonly known diminsions, are not the only ones that exist. They just happen to be the only ones our senses can detect and brains can understand.

Like, Pac-Man can't see up or down. The ability wasn't useful, so evolution ignored it. Picture a 3 dimensional torus, turned vertical, superimposed through pac-man's 2 dimensional universe. He would see 2 seperate points in space, and could mathematically measure heat transfer, electrical current, vibration, etc being transmitted magically from one point to the other.

I always wondered about how gravity, magnetic forces and electromagnetic radiation would look if we could access other dimensions of our universe.

Perhaps if, in addition to X, Y, Z and T, we could see into dimension B, things like magnetism and gravity would be easier to understand.

Our universe itself could be finite. But our universe has to be in something. Something has to contain it. But what is that? And what contains whatever contains our universe?

It hurts my brain.

Sure, because we're looking at a 2D surface in a 3D space, to make it easy to visualize. This is helpful because the surface-of-the-ball 2D surface is a curved space, and at the level that we interact with space on a day-to-day basis, space is flat. We have no experience with curved space, so we have trouble visualizing or even imagining it.

It's just an analogy.

You can have the surface-of-the-ball 2D surface be a 2D space, with no other dimension to go "somewhere else," too. You just can't visualize it.

The latest theory ,do we exist in a simulated setting created in posterity by man. This theory is being touted by several respected theoretical physicists.

Actually, the generally accepted theory is that the universe is all there is, and that in fact there CAN'T be anything outside it to contain it.

It can be partly cloudy either day or night.

Go back to page 3 and look at the picture I posted. Taken by Hubble in a region thought to be empty of any celestial objects. They were wrong. They found thousands of galaxies where there was supposed to be nothing. There's your answer. The universe never ends. Big Grin

The most basic Zen koan is mu, "nothingness". If I ask you to think of nothingness, most people picture blackness in their minds. But that's wrong, as blackness is something.

Whatever that not-blackness is, the Universe is sitting in it.

Similar to unishot, but different -

Sometimes it is not as important to have the right answer...

as it is to have the right question
