It does not speak for any situation before t=0
A QGT will have something to say, one day in the future.
So you actually understand the time existed before the Big Bang. Finally we agree.

When Reality is being discussed, reified abstractions should not be presented at all, let alone be presented as Fact!
So you actually understand the time existed before the Big Bang. Finally we agree.
Are you saying Quantum Mechanics and Relativity should be discarded out of the science? What theories then do you believe in?
According to the BB time [ and common sense]time did not exist before t=0.
In fact as I said, the BB does not speak of anything before 10-43 seconds.
A QGT will throw light on the quantum/Planck era.
Do you understand yet?
Until a validated observable QGT is formulated, whatever you say about before t=0, is just speculation.
It's not a matter of believing in anything. It's a matter of being objective, using common sense and logic, and recognising what the data is telling us.
And that is our Universe-space-time evolved and expanded from a hot dense state.
It is completely irrelevant what absolute time it is. It's artificial book-keep information, an abstract time reference frame like the birth of Jesus.
I was replying to this:
- "When Reality is being discussed, reified abstractions should not be presented at all, let alone be presented as Fact!"
Do you agree with that?
Not really. The poster in question seems of the subjective opinion that reality does not exist in anything other then what he can touch, feel, or smell.
"If we knew what it was we were doing, it would not be called research, would it?"
Most theoretical cosmologists and Physicists see the BB as near certain, and in that regards, see it as being encompassed by any future QGT.
Much as Newtonian mechanics was not shown to be wrong by GR, just that GR gave more accurate precise results, while Newtonian mechanics were less accurate, yet still is used for all purposes on earth, and most space endeavours that are undertaken. Reason? The complex accuracy of GR is just not required in sub relativistic scenarios.
So, no, I'm not fooling myself.
Hey paddoboy,
Occam's Razor states that among competing hypotheses, the one with the fewest assumptions should be selected. More complicated solutions may ultimately prove to be correct in the long run, but—in the absence of near certainty—the fewer assumptions that can be made, the better.
Your quote paraphrases Einstein's humorous quote:
"Make things as simple as possible, but not simpler." Einstein
Numbers and equations will always work out to match observation. You can always cram in constants and crap to make them work. What I was pointing out that has changed from 700 years ago to now, is understanding behind those numbers, what you call "reality". It should be pretty clear then there is no such thing as objective reality, but that it changes, it evolves with the time. And sometimes, it devolves, like in the case of QM, SR and GR. I'll write my next book about it, I'll call it: human history of science - the full circle: from sorcery to science, and then back to magic.
Nothing good comes from intellectual overconfidence. And when something does come out, it's usually just ignorance.
Scientific theories strive to model reality as close as possible. And over the last 100 years or so, scientific theories such as the ones I have mentioned, have been shown time and time again, to be as close to objective reality as one would hope to be.
The incredible technological advancements culminating in probes throughout our solar system such as Spitzer, Planck, Kepler, the HST, the "soon to be launched" JWST and many others, are helping in that objective reality.
I'll say it again, the Newtonian mechanics of gravity is not wrong. It is simply less accurate then GR.
The melding of our prominent theories such as BB, SR, GR, Evolution and Abiogenesis are as solid as one would want.
You can argue with that all you want. But let's see you offer something better.
No, all is not known as yet, and it will be a long time before it is.
Biggest problems in cosmology today is getting a better handle on DE, DM and the problem with melding QM and GR.
I humbly stand by my claims as a layman re the solidity and concreteness of those theories mentioned.
That's not to say their won't be some tinkering around the edges, but the overall picture of the main gist of what those theories tell us should remain as is.
As I have said, a future QGT will almost certainly encompass the BB.
Your faith in science is as strong as it is blind. That's why you'll go to science-heaven, and I'll burn in science-hell. Just teasing, you're all right.
You do know we have three alternative pushers here that all claim to rewrite 20th/21st century physics and all have ToE's?
And they all love me to boot!
paddaboy,
I, for one. Yup, we're buddies, but I am unaware of the other two guys and ToE's.
paddoboy,
As to luck, I'm sure I'll need it since there will be a steep hill to climb that must start from experiments and observations that must contradict mainstream theory and instead support the new theory.
