The debate on the fourth dimension started when Jean Le Rond D’Alembert mentioned this term in the late eighteenth century. But researchers have long assumed another dimension besides the third dimension, which they termed the fourth dimension. Mass bends spacetime and gravity is the measurement or representation or perception of that bending.Whatever we experience comes under the space of three dimensions. Gravity doesn't "move" through time any differently than anything else does. In special and general relativity, changing between frames of reference require considering all 4 in a way that's not much different from rotating graph paper and then needing to change the how define the points (that is, you have to give the same points different names because the orientation of the graph paper is different even if the points/shape is the same). Before special and general relativity, t could be completely separated so it was sometimes talked about as another dimension, but not in a meaningful way. It's usually represented as three spacial dimensions and time although there are some situations where it isn't easy to determine which is which, but I don't know much about that since most elementary courses/texts don't deal with that much.Įvery "event" requires 4 values, x,y,z,t. Or maybe it would get hints of it, but would attribute it to some higher power or call it an inexplicable force. So this either is just false or they exist and we don’t have access to access to them… similarly to how a matter/life confined to a 2D environment wouldn’t be accessible to the 3rd spatial dimension and would be blissfully unaware of anything going on above and below it.
This change in assumption makes a lot of quantum math work out that didn’t with Einstein’s theory, but also could only be true if our universe has 10 dimensions, meaning more than 3 spatial dimensions. That’s the assertion of string theory at least, which (to my understanding) revolves around the assumption that the smallest particles behave more like strings than points (as previous models, including the theory of relativity had assumed). But there’s still theoretical possibility of 4+ spatial dimensions. Right… in Einstein’s theory, time is the 4th dimension that makes up the single spacetime “stage” in which matter occupies.
