Thread: If matter cant be created or destroyed, where did all this stuff come from?

Possibly.

I'd say time exists in the same sense that gravity exists. We can see neither with our eyes, but we can observe the effect they have on the objects around us.

Actually, we have seen gravity with our eyes (ie, the observance of light bending as it passes near black holes or stars), and we have been able to experimentally confirm it as an actual force that can be observed, measured, and, theoretically, changed.

We still don't know what gravity is or much about how or why it works, but it does exist empirically. And no, I'm not going to define "exist;" I think you know what I mean. ;

I don't see how observing that light bend due to gravity is different than observing that objects change over time. I'd say time can be observed, measured and, theoretically, changed just as much as gravity can. More, actually, as I don't see how gravity can be changed, while we have proven through experiments that time moves slower when you're travailing faster (compared to another reference system).
