ATDTDA 752

[David Morris]

I'm not very math conversant, and I never made it all the way through
Stephen Hawkings Brief History of Time, but I remember his description
of a 3-D graphing of a time-event (I think it's called):

If time progression follows a straight line, then an event occurring
somewhere along that line forms a kind of cone spreading out behind
it:  a progression of expanding concentric circles getting larger as
one travels *back* along the timeline (like the expanding ripples of a
drop into a still pond).  So if one were to stop traveling along the
timeline and instead traveled at right angles to that line, one would
experience the history of one moment, but not the whole history, only
a very thin slice of the expanding circle of that moment which has
continued along the timeline beyond where one has stopped to take a
right turn.  One could only experience the entire history of that time
event if one could move perpendicular to the timeline in all
directions at once.

Anyway, that's my rough stab at this AtD quote.
