Why are these pictures misleading? — Raymond
Hence we can conclude that whatever else might be said about the "argument" in Agent Smith's OP, it reaches the wrong conclusion. — Banno
Right. Time may exist and be real in a lot of different ways. But not as physical.Still when compared in different frames time is very real. — Raymond
I'm bad in Physics but I think I see what you mean. However, time is not a process. Change is. A process is a series of actions, steps, movements, changes, etc., which may or may not have a start and end. Some cycles of actions or events, e.g. the periodic revolution of Earth around the Sun, have no start or end, except if we arbitrarily set them ourselves. Otherwise, they are continious processes. We called such a revolution a "day" and divided it into "hours", "minutes", etc. "Days", "hours", "minutes", etc., which are time representations, do not actually exist: they are names of measurement units created by us.Time is a material process etc. — Raymond
Btw, the Sun does not rise or set, it is the Earth that turns — universeness
Finally, you can also look at the subject on a purely logical basis:
If time really existed, it would be infinite. That is, indefinite and undefinable. That is, it can't exist, at least not for us. So, the statement "time exists" leads to its negation! :smile: — Alkis Piskas
If time exists (literally, physically), it is infinite, since it has no start and end. That is, it is indefinite and indefinable (it cannot be described exactly). Thus, it does not actually exist, at least for us. So, the statement "Time exists" leads to its negation — Alkis Piskas
a perfect clock, the one used by Einstein to put on the time line, pointing to values indicating it's position on the time axis. Every value on the axis is a pointing of the clock's hand to a value. Time "derivatives" can be viewed as the variation of the tictac rate between the clocks in two close nearby points in space. If there is a difference between these rates, meaning the "time gradient" is non zero, an object set free falls down, which is easily understandable if you envision the object in outer space and we accelerate towards it. For you, co-accelerating, the clocks in your frame tictac with varying speed.does not exist
So by your reasoning, could you say that what is called 'the centre of the milkyway galaxy' rotates around the Earth? — universeness
I know of no documented text, traced to Einstein, where he states or even implies that it is valid to posit that an Earth-centric view has any validity. — universeness
The acceleration is absolute, but the rotation isn't."
Is that not because there is no acceleration involved in Earth's rotation. — universeness
Yes, I have heard about that expression-term, also a very long time ago. It seems that it has faded away! :grin:Each still image is 'recorded' on the physical medium called the 'fabric of space' — universeness
Yes, figuratively. And in your mind. In your mind you can do a lot of things, you know! :smile:when you look at a photograph you are actually doing time travel in a very real sense
As a photographer, I produce evidence every day that time travel into the past is real. — universeness
Yes, I like it. I already mentioned it's quite interesting.My use of 'I' in the paragraph above is, of course, just my attempt at representing the old photographer. I just find this a very interesting viewpoint. It is scientific evidence of the reality of the concept of 'past', well what do you think? I for one, like it. — universeness
I can accept "making no sense", althought it is not so appropriate in here. But what I cannot accept is "being noonsense", which is an offence and totally inappropriate in this place, as well as other serious discussions in public. Anyway, I have ignored even this too, to see if and what you really have to say about my reasoning about time and infinity.I think this makes no sense, or that it is nonsense. — Raymond
I have not mentioned anything about "clocks"!Time could have a starting point that is different from the time that is measured by the clock. Etc. — Raymond
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.
