Without matter and energy, what exactly does GR relate to at that point?
Spacetime.

Matter/energy allow us to
measure and
detect spacetime, but in no way says that spacetime is dependent on them.
What is it dependent upon?
The way you are usign it, "dependent upon" = "cannot exist without".
Objects in motion stay in motion. "Spacetime" can expand as the objects expand, but "space" does not expand in labs on Earth.
Spacetime expands but the objects don't. And you are correct, spacetime does not expand in labs. But it does expand in intergalactic space. This article -- Lineweaver CH and Davis TM Misconceptions about the Big Bang, Scientific American 36-45 March 2005.
Misconceptions about the Big Bang: Scientific American -- will help explain it to you.
The empirical difference is that we *do* expect to find them "eventually" in physical experiments, whereas inflation is nonexistent today and therefore it will forever be an 'act of faith' on the part of the believer.
The Big Bang is nonexistant today, but it is not an act of faith. Big Bang left
evidence we can study today. Same with inflation. That's why I posted the
scientific papers. The present is the way it is because the past was the way it was. Inflation affects how the present is and thus we can study it.
For good or bad, it's not any different from an ordinary religion in that respect IMO.
In this case, your opinion is in error and does not reflect reality. BTW, religion differs from science mostly in the type of evidence allowed. Science only allows intersubjective personal experience. This is a subset of personal experience. Religion allows the entire set of personal experience. I suggest the book
Religion and Science by Ian Barbour to explore the similarities and differences between science and religion.
What do you make of John 17?
Jesus seems to be talking about a shared community, but not pantheism. If you adhere to Adpotionist Christianity, Jesus is the adopted son of God, and the verses would be interpreted as God adopting everyone as He adopted Jesus.
If you adhere to standard Christian Trinitarianism, then Jesus is inviting people to a shared community with him and God, where God regards them the same as He regards Jesus. The wording is symbolic, not literal. You can tell that by the groping nature of the verses and the similes:
"16
They are not of the world, even as I am not of the world. (this also denies pantheism because pantheism has God and the world being the same thing; this clearly separates them)
...
18 As thou hast sent me into the world, even so have I also sent them into the world. (again, if God and the universe were the same thing, then God would not have to send Jesus 'into the world")
19 And for their sakes I sanctify myself, that they also might be sanctified through the truth.
20 ¶ Neither pray I for these alone, but for them also which shall believe on me through their word;"
Now look at this:
"And the glory which thou gavest me I have given them; that they may be one, even as we are one:"
That verse denies pantheism, because you don't believe you are part of everything in the universe, do you?
The problem is that there can be no "empirical data" related to inflation here and now. That is also true of "dark energy".
It's not true about either one. I posted references about empirical data supporting inflation. Below are papers with empirical data supporting the existence of dark energy: basically the universe is expanding faster than it should:
7. J Glanz, Exploding stars point to a universal repulsive force. Science 279:651-652, 30 Jan. 1998. New data indicates the cosmological constant is back.
7a. J Glanz, No backing off from the accelerating universe. Science 282: 1249-1250, Nov. 13, 1998. As the title says, 2 independent and competing groups continue to get data that agrees.
8. G Tarke and S.P. Swordy, Cosmic Antimatter. Scientific American, 278(4): 36-41, April 1998.
10. CJ Hogan, RP Kirshner, and NB Suntzeff, Surveying space-time with supernovae. Scientific American, 280: 46-51, Jan. 1999. Studies indicate that the rate of expansion of the universe is accelerating.
But Guth's "entity" (if you don't like deity) was 'supernatural' in the sense that no other vector or scalar field in nature retains near constant density over multiple exponential increases in volume. That's about as 'supernatural' as it gets.
No it's not. No other process in the universe gives design except natural selection. It doesn't make NS "supernatural". That inflation does something unique doesn't make it supernatural either.
But meteors do crash into planets and we've documented that fact. These things happen *ON EARTH*.
A meteor that size has never impacted on earth where we can study it in real time. Nor have we ever witnessed a mass extinction due to such an event. Why did all the dinos, most the birds, some reptiles, and some amphibians perish, but not others? We can't go back and watch and we can't recreate it in a lab. Your criteria was that it can happen in a lab.
BTW, we've never had a black hole form on the earth, either. So we can't study a black hole by the effects on the surrounding spacetime?
Demonstrate it. Show me that inflation has some effect on photons.
On the
density of photons. That's what the cited papers did. Read them.
But again, you're comparing inflation (which doesn't effect the earth today) to Earth itself!
No, I'm showing you that it's possible to prove a negative. This is what you claimed:
"I can't "disprove" something that doesn't even exist,"
I showed you that claim was false. Now you are moving the goalposts. What's more, I showed you how inflation
could have been disproved, but it passed the test:
"What you do is
disprove inflation. The fine scale maps of the CMBR
could have disproved inflation, but they didn't."
Back to the papers. Read them.
No. I am a 'Christian'. That's technically my "religion".
Sorry, but technically that is
not your religion, because Christianity does not allow pantheism. You are a pantheist who believes Jesus was God. But then, pantheism believes a tree is God, a rock is God, you are God.
I simply see pantheism as a scientific alternative to mainstream cosmology theory. It's just a "scientific theory' IMO, nothing more.
If pantheism is only a scientific theory, then you shouldn't be trying to use scripture to demonstrate it.
Please do me a favor, because I don't want to scroll thru the whole thread. List for me the
unique observational consequences we should see
today if pantheism is true. That is, observations that would be there
only if pantheism were true and are unexplained by any other theory. Scientific theories have these, so if you claim that pantheism is only a scientific theory, then it
must have these. Thank you.
Yes, and from the standpoint of empirical physics I believe it is more likely to be "true" than mainstream cosmology theory.
At this point I need to ask you what you think pantheism is. In the standard discussions of pantheism --
Pantheism (Stanford Encyclopedia of Philosophy) --, I don't see how pantheism is going to differ from mainstream cosmology. If God and the universe are one, then pantheism would just have inflation be another part of God.
