I was pondering the defining of time, mass, or matter ... wondered if any one could help .... However! First ponder this. obviously speed = distance divided by time ... and ... mass = weight x gravity The first question i ask. Can one of these variables(in their respective equations) exist with out the other? for ex. If there was no movement then there could be no time. Obviously there is no distance .. since there is no movement. Then in the begining was there no time .. before the "proposed" big bang theory. My friend argue there was still time but not in the sense we could comprehend. ? any theories ..... propose you were in the middle of space ... where there were zero gravity .. then you would have no weight ... but wouldnt'y you still have mass .. or would you be massless ??? obviously you are still there.. so maybe theres is no such thing as zero gravity .. . So my question is .. is there always gravity on a body .. maybe like a " limit" process so minute to you seem weightless but really you are not. therefore you would always have mass ...So then What is matter .. ? i only ask that if one could prove zero gravity can be obtained.
