Time passes with a specific rate that can be experienced. This passage slows down near heavy objects. Gravitational waves have been observed!RCSaunders wrote: ↑Tue Feb 22, 2022 11:18 pmAn electron has mass, charge, size, and other physical characteristics. What physical characteristics does time have? None, because it is not a thing, not an entity, not a substance or any kind of, "stuff." It is an attribute of the phenomenon motion and sans motion does not exist at all.Ah, yes. No color at all.Exactly nothing, because time has no attributes of a substance.bahman wrote: ↑Tue Feb 22, 2022 6:17 pmI don't think that time has mass.It doesn't have any shape. It exists at now. It can be slowed down around a heavy object.I said enough about the properties of time.RCSaunders wrote: ↑Mon Feb 21, 2022 5:18 pm Name one property time has that can be observed or detected by any physical means.The so-called geometry of space is a metaphorical description of the bahavior of physical entities, not a description of some kind of, "stuff." Einstein himself rejected that view.bahman wrote: ↑Tue Feb 22, 2022 6:17 pmWrong. Space is a substance as well. It bends around the heavy objects.RCSaunders wrote: ↑Mon Feb 21, 2022 5:18 pm Time is no more a substance then length, volume, or weight are substances. Time is a metric, a way of measuring the relationship between different motions and nothing more.
I have no idea why it bothers you that time and space are not entities or substances but merely ways of describing the relationships between things that really are entities and substances unless you are trying to promote some supernatural view of reality.
