− | + | {{incomplete|First version of explanation: revised}} | |
+ | Our world is {{w|Dimension|3-dimensional}} (like in a box; length, width and height.) But in modern {{w|physics}}, {{w|space}} and {{w|time}} are unified in a four-dimensional continuum called {{w|Spacetime|spacetime}} where time becomes the fourth dimension. | ||
− | + | It is to this 4-dimensional spacetime that [[Cueball]] refers in his monologue to [[Megan]], while he is philosophizing about his life in these four dimensions. | |
− | + | What Cueball comments on is that whereas we can, to some extent, determine in which direction we wish to move (at least on the surface of the Earth) in the three dimensions of space (up-down, left-right, forward-backward), we cannot help but being pushed ''inexorably forward'' through time. So it is quite lucky for Cueball that he thinks this is OK. | |
− | + | Being pushed in one of the other directions could be lethal, if you where pushed hard enough against a rock, over a cliff or in front of a truck... | |
− | In the title text | + | In the title text he then continues to muse about his favorite dimensions and places time in his top three dimensions. This means that one of the three space dimensions would be his least favorite. But in space, there is no difference between the three dimensions. It is only in a fixed reference system that you can assign any difference to these three directions (like on Earth). So this doesn't make any sense. Either time should be his favorite or his least favorite dimension. So if it is in the top three out of four, it must be number one... Either that, or Randall was making a joke. |
− | Previously Randall has made a comic about a man who was pushed sideways | + | However in {{W|M-theory}}, a theory that unifies all consistent versions of {{w|superstring theory}}, spacetime is eleven-dimensional, which would make a place in the top three a somewhat more interesting position. However, these extra dimensions are not currently detectable. |
+ | |||
+ | Previously [[Randall]] has made a comic about a man who was pushed sideways (although still held in place by gravity?) - so he was pushed both through time and to the side: [[417: The Man Who Fell Sideways]]. On a similar note in [[1376: Jump]] Cueball suddenly slides off without falling down after a jump... | ||
