Nah, I am not going to answer this question. (Actually, I am not really sure what this question means. You can ask me if I think time is a dimension, then I'd say yes.) I just read this discussion of the question that Wired lists as the second on its list of 'big questions' (another one is 'Why is fundamental physics so messy?'). I just thought it might humor you what people had to say about it. It seems if we'd take a vote on it, the majority believes time is an illusion. Feel free to let me know your opinion.
From the comment section:
Roberto: The unidirectional time in the equations of physics is constructed from the original, circular time.
(now that explains everything)
Guest: does time really exist? Not in the least. Time is a construct. Created by mankind to assert ourselves over the other dimensions. We have freed ourself from the laws of physics and created a new prison, time.
(Gee, I didn't even notice we freed ourselves from the laws of physics. That's what can happen if you live in a small city in west Ontario - someone could have told me!)
Guest: if you ever get the opportunity, use DMT (dimethyltryptamine). you will see far beyond the illusion of time and realize many things that cannot be expained.
Guest: Time is an invention of convenience. Kind of like x^^0 = 1 .
(Aside: this is not an invention of convenience but a consequence of smoothness)
Guest: It's a tautological question. Time is what's measured by a clock, just as intelligence is what's measured by an IQ test.
(Comes back to the point that the question, as formulated, is essentially empty.)
Eric: Human sentience requires this illusion to give us the illusion of free will.
Robert: there is no such thing as time, instead it should be thought of as the cycle of mater and energy from light to total entropy to highly energized quantum materials which all together form the macro world
(thats what happens if you 'think horizontally')
Pierre: If we are going to think about time, shouldn't we first ask ourselves "are thoughts real?".
(I link therefore I am).
Jeff M: It doesn't matter - the question is moot.
(Thanks to Jeff M for enriching my vocabulary, I agree. Will try to use 'moot' from now on instead of 'nonsense'.)
pachorazy: if we change our perception of time can we change how fast we age?
(and how do you measure 'fast' if not with 'time'?)
Stuart: I suppose that it does not matter. Time is how we perceive it. What it may theoretically be has no effect on how it IS for us. So... it is what it is.
letibenson: Time is an allusion and here is why-- our congress can tell us when we need to set our clocks forward or back by an hour. If time was real it would be out of there hands
tculp: If we break down the question, we have an initial question - what is illusion?
Time flies like an arrow, fruit flies like a banana. (From the book "Instant Physics")
Alex: Time is a man-made idea, it is a construct of human society used to make life more convenient and easy.
Gary: It might be time to go back to the Greek philosophical definition of the universe and work our way forward again.
(have fun, say hello if you arrive in the 21st century)
Robert: the fascination that many people have these days with wanting to believe that everything happens all at once, there really is no time.
JD Bailey: Time is not an illusion. Time is a multidimensional relationship.
Jim: Life is illusion and time comes from life.
Ric: One of the secrets of TIME, which I have realized, is that TIME itself is the constant we call “infinity”.
Erika: And what about killing time?
Jana: Time is fake. Have a nice day.:)
