I've been reading all about time cones, and space-time, and those general ideas. i forget if i already posted about it a whil ago, but if i did, obivously i didn't quite get the right answer because i still don't understand it... but i was looking at a picture too in an astronomy book a while ago. and it was a drawing of a circle with the big bang as the perimiter. the very center was the present. and space-time went outward from t here towards the big bang. at the time i thought it was a great representation, but the more i thought about it the more confused i started to get. then i was thinking about light cones. and that picture sort of makes sense again... i think. in those light cones, the present is only one point in space time, just like the center in that picture. and i guess we're always traveling towards the center of the picture, which is the future, but we're actually always exactly at the center. and we can only observe the space that expands outward from us, which is the past. i dunno if i'm missing anything else...... umm, i had a question when i started... but its kind of dissapeared when i was trying to figure out how they were related. either way, does that sound about right? or make sense? and is that a good way to think about it at all?
