OK. Now what? There is no *logical* contradiction involved in an infinite time into the past any more than there is for an infinite time into the future.
I think I have already covered infinite regression several times. I do not know how else to say it, you can't span an infinite number of past events to arrive at the current one. Concerning the future, it is a potential unbounded finite, not an infinite.
Exactly. But the universe was never in such a state infinitely far back. It has always been in a state finitely far back. But each state finitely far back came from a state slight earlier.
Your like a chronological nihilist or chameleon.
OK, but you claimed there is a *logical* contradiction to an infinite time into the past. Have you given up that claim?
Are you asking about the semantic technicality of the terms "logical contradiction"? I was using it as shorthand, if so, I would have to look it up. I think the actual specific labels should be logically incoherent not contradictory. It is hard to contradict the lack of a thing.
If so, that means we have to address the possibility of an infinite time into the past.
No this is an attempt to use semantic technicality to resurrect an argument found only in the abstract.
And, currently, there are two main options (duh): time that is only finite into the past and time that is infinite into the past.
No there are 3 if infinite time is included. There is also tense less time. As bad as it is I consider it more likely than tensed infinite time.
The B-theory of
time is the name given to one of two positions regarding philosophy of
time. B-theorists argue that the flow of
time is an illusion, that the past, present and future are equally real, and that
time is
tenseless. This would mean that temporal becoming is not an objective feature of reality.
B-theory of time - Wikipedia
The main arguments for a finite time derive from the BB model and general relativity. It is a fact that general relativity inevitably has singularities. For cosmology, those singularities limit the time coordinate to a finite value into the past.
Yes, this is the only theory of time which has evidence for it. Any additional theories only exist (at least as far as we can see) in someone's mind.
The main counter-argument is that general relativity is known to be incomplete: it doesn't incorporate the known aspects of quantum mechanics. For a *long* time, we didn't know of any way to reconcile these two central ideas about the universe. Now we have several proposed quantum theories of gravity: string theory, quantum loop gravity, etc. But in *all* of these, the singularities of general relativity are 'smoothed out' and time does go infinitely far into the past.
This is the same kind of argument as my motorcycle's engine refrigerating it's self. It might look possible in some abstract model, but the model seems to contradict actual experience and data. I do not understand the desire to be chased completely out of known reality to escape the only ultimate hope for mankind. It is really strange to observe from my side of things.
So, at this point, we do not know if time is infinite into the past or not. And that is my point. It is *logically* and *observationally* possible for either to be the case.
We are stuck exactly where we started. I started by saying that people will take science on faith but demand proof for God. The merit of their arguments will merely be that it can't be shown to be impossible.
Huh? The BB model is a four dimensional model for spacetime. The images you have are simplifications to get the idea across. Most people don't deal with four dimensions very well, let alone curvature of four dimensions.
I do not have any images. I was talking about every single image I have ever seen when I looked them up. Even the cross sections assume volume. The only exception would be that flat oval you see modeling the background radiation, but it is not supposed to represent space to begin with. Show my what would stop things from expanding in the spherical shape we so often see with our eyes. Was there some kind of preexisting mold that forced the universe to only expand in directions you found convenient? Have you ever heard the expression of "educating ourselves into imbecility"?
No, you didn't. You just showed that infinity-infinity isn't a meaningful thing. That was your whole 'contradiction'. Yes, if you have an infinite number of things and take away three, you still have an infinite number of things. Yes, if you have an infinite number of things and you take away 10, you still have an infinite number of things. And yes, if you have an infinite number of things, it is possible to take away an infinite number of things and have an infinite number of things left over.
Forget "contradiction", I was not being semantically precise. I am pretty sure the proper terms are logically incoherent.
Where is the contradiction?
Do you also have a degree in obsessive semantic technicalities?
You claimed logical contradictions. There are none.
My goodness, your locked up. Are you old enough to remember what it sounds like when a record would not let the needle out of the groove? Logical incoherence for pity's sake.
yes, I am responding to what you said. Yes, it has gone on for an infinite amount of time. Where is the contradiction?
This is worse, when records skip you could always throw something at the record player to make it do something else.
I'm sorry for your significant other? I'm not sure what the relevance was for that comment.
What are you talking about? You said that we had only figured out all this infinite past stiff after the BGVT was announced, I replied that they announced the BGVT in 2003. What significant other are you talking about?
They have been *modified* by the new insights. But I agree, these new insights have not been *proven*. But the point is that they are *possible*. You claimed they are not even logically possible.
I find only accepted models as persuasive, in fact I usually do not consider theories as new as BGVT to be persuasive but it's robustness makes up the difference. Got to go. Get to the rest soon.
