In a world with 1 dimension you can move in 2 base directions. With 2 you can move in 4. With 3 you can move in 6. How many base directions can you move in a world with all 4 space-time dimensions?

Humm.. The fourth dimension is time - but why is it considered a dimension along with the 3 familiar spatial dimensions, since, to us, it seems distinct? The answer is that it turns out that the 3 spatial + 1 time dimensions are actually completely intertwined. This was one of the major revolutions of thought coming from Einstein's special relativity. Clearly, we can move through the 3 spatial dimensions - we do it all the time. Also, clearly we move through time, because yesterday's actions affect today. However, it turns out that moving through space changes the way we move through time, because, mathematically, they are not separate 1-dimensional and 3-dimensional spaces, but a single 4-dimensional space. If you're familiar with vectors, you can sort of think of it this way - in a 2-dimensional space (like the x-y plane), if you have a vector of fixed length, rotations of that vector in the plane change the length of the x- and y-components. Rotating toward the x-axis shortens the y-component, and vice versa. Now, replace the y-axis with a t-axis (for time), and pretend the vector is representing our velocity through spacetime. If I rotate the vector towards the x-axis, it shortens the t-component - meaning if I am moving faster in space (x-dimension), I'm moving slower in time. Special relativity is sort of a generalization of this to 4-dimensions. All objects are moving through spacetime at a velocity of c, always. Moving faster through the 3 spatial dimensions rotates that vector away from the t-axis, meaning we move slower through time (called time dilation). No experiment has ever shown that special relativity is incorrect, so we must accept the fact that time is simply one dimension of a 4-dimensional spacetime. [spoiler]Someone needs a hug[/spoiler]

Edited by wavefields: 3/18/2016 8:31:04 PMGoogle the Montauk project. time is space and therefore moves in all directions, relatively speaking an octahedron represents 4d space time, each corner representing a certain angle of reality, up down left right and time and their anti versions

Edited by Deleted User: 3/18/2016 4:37:00 PMEach of these have at least 1 dimension of time right?

Three?

I want to follow the pattern and say 8 but I guess that is wrong.
