Isn't so called (velocity/gravitational) time dilation, a case of warping the 4th dimension (time); however, unlike space in which case a straight line becomes a curve, with time, a curve becomes a straight line. — Agent Smith
so, expansion of space, is the notional 'clock' ticking. The current expansion rate is accelerating — universeness
Curvature occurs in spacetime, rather than in 3-D space is my (pathetic) understanding — jgill
One of the most profound questions which can be asked is 'what is truth? — universeness
Depends who you ask it. For a lot of people the clock is very real and they fight it, save it, buy it, or kill it even. The clock can go awfully slow when waiting. Don't think about the clock! — Raymond
What the clock measures is change. The measurement of change is time, like the measurement of space is length. Clock is to the ruler as time is to length.What the clock measures.
Basic idea = Something that can't be broken down into simpler ideas. Ergo, is undefin(ed/able). — Agent Smith
What the clock measures is change. — Harry Hindu
Thats the definition if time that works for me. Nothing else is needed. Why dont you tell me what I'm missing — Harry Hindu

Assume R = Time is real — Agent Smith
All that is required is the laws of the universe, and memory. Time as a real thing seems inessential to explaining what we experience. — hypericin
"Real" is meaningless until it's explained, so the rest is also pointless. — Xtrix

Yeah, so we just don't know enough yet — universeness
Space expands, objects such as solar systems or galaxies do not expand as they are gravitationally bound. A common analogy is pen marks on the surface of a balloon being blown up — universeness
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
