Some Theories

Time Is The Fourth Dimension

Hold up. Wut.

Okay, so. Do you remember reading Flatland as a kid? No? It was only my elementary school that required us teeny little youngsters to try and wrap our cute little minds around this REALLY COMPLEX CONCEPT THAT EVEN A LOT OF ADULTS STRUGGLE WITH? Oh, okay, cool.
Well then. Flatland is a story about a two dimensional square who lives in the second dimension with a whole bunch of other two dimensional shapes. Living in the second dimension, being two dimensional, means they all have two dimensions, right? Length and width. Yeah? Except, what the square and all the rest of the shapes don't know is that they all have a third dimension. Height.
They have to. In order for things to exist in the two dimensional world of Flatland, in order for the shapes to be able to roam around, there must be an empty space within the second dimension which is determined, and bounded by that third dimension. The second dimension is, therefore, embedded in the third dimension. Everything in Flatland has height. Everything in Flatland has the SAME height. And that's why they can't perceive it. If everything is exactly the same height, including everything you would use to measure that height, then how can you even tell height is there?
Then the square meets a sphere. Not a circle. Not two dimensional. A three dimensional. Motherficken. Sphere. At first, the square thinks he's going bonkers, because when the sphere appeared to him he was a very small dot that suddenly became a very small circle. Then the circle started growing wider and wider, then suddenly smaller and smaller until it disappered. It was the sphere passing through the square's living room.
Then this sphere goes "I can shooow you the wooorld!" And literally takes the square to the first dimension. Shows him how the one dimensional dots exist. How they can only see their width. They don't know they have length. But they have length. Then the sphere takes the square to the nonth dimension. Shows him how a zero dimensional creature exists. It only knows of it's own existence. It isn't even aware of anything outside of itself. It believes it's the only thing that exists, and this makes it very happy.
Then the sphere takes the square outside of it's second dimension, into the sphere's own third dimension, and shows the square what his home looks like from the side. He shows the square how everything in his dimension has height, though no one in his dimension can see it. He then goes on to explain how the same is true for the sphere. The sphere has some "greater height" that he cannot see. Then the sphere sends the square back into his own dimension to preach the gospel, and the other shapes imprison him due to insanity. The end.
Now, it's been a long ass time since I've actually read Flatland by Edwin A. Abbot, but you should read it. It's really short, and has a lots of pictures and diagrams. Is nice. Plus, I'm not sure I'm getting the order of events right, so there's that. Anywhoozerberries.
So, we exist in the third dimension, yeah? We are all three dimensional beings. We have three measurable dimensions. Length, width, height. Or length, width, depth. Whichever you prefer. As the second dimension was embedded in an immeasurable third dimension, and as the first dimension was embedded in an immeasurable second dimension, and as the nonth dimension was embedded within all higher dimensions, so too is our little three dimensional world embedded within a fourth immeasurable dimension, and all other higher dimensions which we cannot even begin to perceive. Still with me?
Cool. String theory suggests there are ten dimensions. Each of these dimensions binds and determines everything in our third dimension. What does this mean? Well, like how everything in Flatland is the exact same height, because height is the dimension that binds Flatland, as well as determines the height of everything in Flatland, everything in our dimension that always remains consistent, no matter what, is that way because of a higher dimension. We know that if we take the circumference of a circle divided by it's diameter we always get pi. Why tho? Why is it that no matter what the radius, the circumference divided by the diameter will always yield the same magical, infinite number? String theory suggests it's because that's the "shape" of one of the higher dimensions. Getting it?
Good. I believe time is the fourth dimension. I'm not alone in this. I have two reasons for why I believe this. The first was explained to me by the amazing Neil deGrasse Tyson in a lot of different discussions, but a link to my favorite video is at the bottom. It's thirty minutes long, and every minute is WORTH IT. The other reason I believe time is the fourth dimension I concocted on my own.
The first reason, brief paraphrase here, is that you cannot meet someone at a place, but not a time. Alternatively, you cannot meet someone at a time, but not a place. Time must be a crucial fourth dimension that we cannot measure if time marks an intersection between things.
The second reason, from inside my own brain, is because everything that exists in our dimension which we use to measure time, measures time at the exact. Same. Rate. A second is always one second long. A minute is always one minute long. An hour literally always takes exactly one hour to pass. Regardless of whether it's the clock on your phone while your scrolling through Facebook, or the clock on the wall at work an hour before your shift ends. That hour passes at the same rate. Though it feels like the speed fluctuates, doesn't it? Sometimes, time moves a little  faster. Sometimes, time moves a little bit slower. We all feel this. Yet not a single device we have ever invented to measure time captures this fluctuating speed. Every second hand on every watch ticks forward at the same. Time.
If we could find a way to measure a perceivable fluctuation in the rate at which time moves, we would definitively prove that time is the fourth dimension, and can move in more directions than just how we see it. Time, in our third dimension, only moves forward at the rate of one second per second. Time can move faster than that. Time can move slower than that. Time can stop. Time can go backwards. Time can skid sideways. Time can swoop around in fun little spiral shapes. Time doesn't have to always go forward at the same slow, agonizing pace. We do. That's how we move through time because that's how we exist in time. We all must march ever forward. No pausing. No looking back.
I'd like to believe it's possible that eventually, we will all evolve to obtain the ability to climb out of this endless current, beyond the need for a three dimensional form, into the great unknown. But that's just a theory.
