Maybe I'm lost, I still know little about physics (so please don't judge to harshly ), but this whole time as a 4th dimension is really triggering some weird and probably absurd thought. I read that to visualize time being another dimension, we must somehow add another axis to the x/y/z grid in such a way that it is perpendicular to these axis. I know that this is impossible to visualize, but I don't see how this logically makes sense. Is time a dimension that can be depicted visually, or is just a component of space? If it is a component of space, why don't we visualize a "unit sphere" on the x/y/z grid, and then use time as a magnitude of all the axis and thus the sphere? In this way, an event would be described in space and time. It also seems analogous to the Bing Bang theory, maybe because it's a ball expanding from an infinitely small point (the origin of x,y,z). It is also a good visual for the "end" of the universe (that is if this whole idea isn't too far off), because it would show that the universe doesn't end (at least it would appear that way to us) because we are simply too far behind in time to catch up to the "surface", if you will, of the sphere. If this could be possible, what would the negative values of each axis mean, anything? Or do they just represent all directions? I'm so lost, be gentle ![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
