The Nature of Time

[dpgillam]

Ihoe:

If I understand you correctly (and please feel free to correct me) you are saying that time is a separate entity running beside the 3 cartesian axis; sometimes interacting, and sometimes not, and not to be measured the same way.

 

A gross oversimplification (and slightly inaccurate, I'll admit. Im groping for words) might be the statistics quote "Correlation does not imply causation." That is, these two different entities are usually found together, but not often found affecting each other?

Location is irrelevant to time. Even if you don't move, time still passes. And it will never reverse course.

 

But, is that passage of time always at a constant rate? Physics tells us it is. Well, for the most part at least, further you get from a gravity well, the rate tends to slow some. Wonder if it would stop completely far enough out. :) And then we have our own perception of the passage of time. Having a lot of fun? Truly enjoying what you are doing? Time flies past.. Bored stiff, rather be just about anywhere else? Time drags out forever..... Is it really still passing at the same rate?

Time doesn´t exist, only the illusion of it does.

 

In reality everything exists simultaneously. Like a movie on a DVD. Wherever you are in the movie is the present, what you have seen is the past and parts of the movie you haven´t yet seen is the future and yet the whole movie exists on the DVD at the same time*

So if time doesn't exist and is only an illusion . Yet both the movie and DVD both exist . Does time still not exist. Seems it would not be so , for if the movie is quantifiable and is as time , so too must time be quantifiable. Oh crap now I've got to go back and watch that crappy movie.

 

The inherent problem with trying to define the nature of time is that we are also subject to time as we are attempting to define it. Its like saying I am deceived and can thus see the deception. The only point at which we can see time for what it is , is by being outside its effects, as it is now the best we can hope for is catching glimpses and hypothesying as to what those glimpses mean.

I'm not sure Astro Physicists would agree with you there.. If we take Hubble Deep Field as an example, some of those galaxies are not only far away but also long ago.

It's looking back over 13 billion light years almost to the big bang. If was possible to look through the opaque soup before light particles were formed we would actually be able to see the big bang happen.

 

So as some one else mentioned wouldn't that make time relevant to the observer, meaning not everything happens simultaneously..?

 

Admittedly much as I love talking about the universe one aspect I cannot get my head around is the timespace constant.... No matter how many ways I look at it my tiny brain still turns to mush. :D.

A neat article by physicist who is among many that says all times exist at once. There are many physicist that question that the "time as a river" concept is just not what really happens and is just our observational perception of it.

 

I do believe that time all exist at once. that doesn't mean I think we can travel between these existences. Perhaps all the different time flows exist in an infinity of universes...who knows. But there is alot of math and even repeatable experiments of he perception of time and how it is different for different people and what is happening to you makes your brain process time differently. So who knows!

Yeah I'm pretty sure the past/present/future theory was behind the Singularity scene in Interstellar where Matt McConaughey saw his daughter.

 

Brilliant movie btw.

 

Edit: one aspect of the Daily Mail article I don't agree with is that laws of physics wiould be the same in a mirror Universe.

I err on the side that theorises laws perse don't exist since the laws are created randomly at the beginning. In other words what applies to one Universe may not in another.

That's part of the multiverse thing.

 

 

Which theory of time proves to be correct, though - Dr Skow's block universe, the mirror universe or perhaps another - remains to be seen.

 

 

Haha...that's optimism for ya.... we will eventually understand time and uncover the secret of the universe. :P lol

Then the universe will change all the questions. Either that, or it will simply end. :D

Large objects such as planets warp spacetime, the distortion we can feel as gravity, time is also affected since space and time are one constant (all theoretical of course),

 

For arguments sake say space is a Trampoline and time is a toy car some kid is zooming from one end of the tramp to the other. More or less the car would travel in a flat trajectory..

Now if we dropped a bowling ball onto the tramp the car couldn't go straight ahead, it'd have to port around the depression created by the bowling ball.

 

This is why time slows where gravity is present, because gravity is just distortion of spacetime.

 

 

Again all theoretical I don't pretend to know this for fact. :D hehe

Bugt we've known the secret of the universe, and the question since 1978.

The answer is 42, and the question is "what is 7x7?"

 

:laugh:

 

But seriously, the question about fluidity of time is a valid an necessary one Im glad was raised, since I overlooked it entirely. Is time only as real as we perceive? There's a story ascribed to Einstein as he was trying to explain relativity to a lay-person, and he said "5 seconds holding a hot coal feels like eternity. 5 seconds Kissing a pretty girl feels like only an instant."

 

I would think that if this is true, and time exists only in how we see it, that as we are tied to the 3 dimensions, time would be a function of them, maybe?

 

And thanks all. I love these conversations, but being a shut-in, have had no one to have them with.
