The concept of cyclic time is just what it sounds like - that time exists in a finite amount, curving like the surface of a sphere, in such a way that, if you were to somehow eternally persist, and you marked a point in time, you would eventually wind up right back at that point again. Minus the possibility of certain random events on the quantum level, the implication is that everything that has ever happened, has happened before and will happen again; there's no reversal of time, there's just a curvature that causes you to come back around again to where you were.
It's a hard concept for most people to grasp, and it's only rendered more difficult when we correct our terminology above and refer to cyclic spacetime. We get further confusion when we start looking into singularities, event horizons, time dilation, etc.
It also might be practically impossible to detect whether cyclical time is true or not. Consider travelling the surface of a sphere: if the sphere has fixed, identifiable features, we'll notice when we come back around to old territory. But if, instead, those features are subject to change without warning, we might circumnavigate the sphere a hundred times and never realize it. Of course, given our familiarity with the three dimensions, we could determine the curvature of the sphere, and thus, the circumference of that sphere.
But with spacetime, we lack the tools and knowhow to determine - indeed, even to describe - the curvature; so determining the temporal circumference of the universe might remain impossible for us for a great deal of time. And if there are truly undetermined, random events occuring in the universe, we wouldn't even be able to find key benchmarkers to recognize when we've been somewhere before. Even if our known universe ends in a 'Big Crunch', the collapse leading up to that crunch would still be moving forward in spacetime. We wouldn't know if spacetime's circumference encompassed one Big Bang, or ten, or 3.5. There's just no practical way for us to know.
Some traditional myths have long understood the idea of the cycle of time - a wheel with niether beginning nor ending. And some people even try to capitalize on it - see: Jordan, Robert.

How many times does a circle go round?So, how many times has time cycled then?
How many times has everything been repeated?
Or has time been cycling for eternity?
How many times does a circle go round?
Incidentally, do you assume that the meaning of "eternity" is "an infinite amount of time"?
Or non-temporal?
Actually that is not called logic, that is called assumption. In order for it to be logic you would have to include some actual logic.It's called logic.
Things happen over time. No time. Nothing happens.
You have posted the sentence so many times, do I need to cite every time you have repeated it?
Okay, it is clear now which sentence you were referring to.
But it wasn't clear from your post, because it seemed unnecessary to make such a distinction.
Or perhaps do you know the sentence I am talking about? If is simply not clear from the context which meaning of "beginning" you are using.
It should be perfectly clear.
The word to use is origin.
By analogy, the "beginning" of a ruler is the bit that has the "0" written on it. The origin of the ruler is the ruler factory, (or the tree it was made from).
What's the beginning of a piece of wood?
Or a ruler without "0" written on it?
You might imagine a ruler created in a circle with ticks but no numbers. There you would have a ruler without a beginning.
Just like a ruler without ticks or numbers written on it.
Or just like a piece of wood.
But it still has an origin.
Fine.
Similarly you might imagine an eternal ruler...
Or you might NOT be able to imagine an eternal ruler, but be able to fool yourself into thinking that you can imagine it.
That is one of my points.
....or a ruler that came from nothing.
Or you might NOT be able to imagine a ruler that came from nothing, but be able to fool yourself into thinking that you can imagine it.
That's my other point.
Thus you could have a ruler with a beginning but no origin.
Again, it is insufficient to just say so, you must be able to demonstrate that you know what this actually means, if anything.
Z has declined, MobySeven hits his head against a stone wall....
...what about Robin?
You need to think about this sentence for just a little longer.BillyJoe:
Also, if you have a proof that there was never nothing (that there is at least one thing that had no origin), I'd be happy if you shared it with me.
"At least one thing had no origin" does not imply "there was never nothing".
If something "came from nothing", then it would have no origin ("nothing" isn't an origin). If something had no beginning then it would also have no origin..
Unfortunately, Billy really really wants there to be a metatime that overlies the concept of cyclic time as well. However, this just goes to illustrate that he has no real grasp of the concept of time. And with no grasp of the concept of time, how can he come to understand much of anything else, on the metaphysical? So of course, as men have done for millions of years, in the absence of understanding, he finds God.
Maybe that's what it all boils down to - God is the manifestation of incomprehension.
Maybe you can explain metatime.
Maybe you can explain time.
Maybe you can explain eternity.
Or maybe you won't explain anything.
(That's more your style isn't it?)
(there, I've said it)

So, how many times has time cycled then?
How many times has everything been repeated?
Or has time been cycling for eternity?
And how does this solve the problem we started with.
EITHER there was a beginning to these time cyles (something from nothing) OR the time cycles has been going forever (time without beginning).
And we still have no understanding of eternity.
(which is what started off this exchange)
I'm okay with it.
I just don't pretend that we have exhausted the need for explanation.
Time extending back for eternity is hardly any different to time extending back in cycles for all eternity.
Yes, just a little bit problematic when you're doing science don't you think.
Like multiverse: A really interesting idea and solves a whole heap of problems, but the price you pay is an almost infinite number of dimensions for these universes to reside in; and how the hell do you prove it?
I was being perfectly rational. It's clear that you don't understand the idea of cyclic time - you've said so yourself, though not in so many words.
Yet the best you can come up with to reply, after restating your insufficient understanding of the concept, is to call me a fake and a liar. A fake what? Where did I lie?
Therefore, I am both reporting your post, and placing you on ignore for the time being.
For the sake of the Gentle Reader....
This demonstrates BJ's misunderstanding of the concept. In the theory of cyclic time, there may be no answer to the question, 'how many times has time cycled', since that would automatically imply a metatime which overlays spacetime. Time simply goes round and round - there's no 'eternity', no 'number of times'.So, how many times has time cycled then?
How many times has everything been repeated?
Or has time been cycling for eternity?
This, again, is a direct result of his failing to understand. In the cyclic time theory, time has no beginning and there is no forever for time to cycle through. It's a close circle, which has neither beginning nor ending.And how does this solve the problem we started with.
EITHER there was a beginning to these time cyles (something from nothing) OR the time cycles has been going forever (time without beginning).
Eternity is not that hard to understand, conceptually. Neither is infinity. But to visualize it...![]()
There's no need to explain it, until there's more information available.I'm okay with it.
I just don't pretend that we have exhausted the need for explanation.
Time extending back for eternity is hardly any different to time extending back in cycles for all eternity.
And time would extend back into the future, if you think about it...
Mankind is not sufficiently advanced enough to tackle eternity via science.
I see no problem with a vast number of dimensions not perceivable by us. As for a proof - why do you need to prove it? If the theory has sufficient predictive power to be useful at this time, that's good enough; and if its predictive power fails us, we change the theory. No problem at all.Like multiverse: A really interesting idea and solves a whole heap of problems, but the price you pay is an almost infinite number of dimensions for these universes to reside in; and how the hell do you prove it?
Nope. if something has an origin it means it has an origin. "Nothing" is not an origin.![]()
Good one Robin.![]()
Firstly and foremostly, if something has an origin, it means it was not there and then it was there.
(As opposed to something which does not have an origin, meaning that it has always been there.)
Okay?
A better word to fit your concept would be "inception""Origin: 2 a : rise, beginning, or derivation from a source b : the point at which something begins or rises or from which it derives <the origin of the custom>; also : something that creates, causes, or gives rise to another <a spring is the origin of the brook>
Merriam Webster Dictionary
INCEPTION stresses the beginning of something without implying causes <the business has been a success since its inception>
Merriam Webster Dictionary
Again, no. If the thing "was not there" then where is "there"? The sentence is simply meaningless. Better to say "something began to exist, had no source and was the only thing that existed" (and I stress again that this does not have to be the case). So if you say it "must have come into existence from nothing" what you really mean is "it could not have come into existence from anything".Okay.
So now, as you say, we will add in the fact that, generally, there must be something for this thing to originate from.
However...
If the thing that "was not there and then was there" was the first thing ever to come into existence, then there was nothing for this thing to originate from and, therefore, it must have come into existence from nothing.
Okay?
And nobody ever suggested that it was.So, this is the problem and the basis of my question:
How could something have come into existence from nothing?
The answer to this question is definitely not:
It couldn't have an origin because there was nothing for it to originate from.
Is that despite the ambiguity or because of it?BillyJoe said:It should be perfectly clear.
The word to use is origin.
