Is Dark Energy a Mistaken Concept?

[KrisZ]

Applying the laws of physics that we know to be true to about matter, to a time before matter existed, may be a huge mistake making it even harder to determine what went on during that practical imposable to understand event.

"Nothing" is absence of anything, it has no relation to the laws of physics. If you have "nothing" you have no laws of physics, you literally have nothing. Unless somehow the the definition of nothing applies differently to the topic at hand?

It's quite intriguing to me that you're now the second person telling me how my logical assumption that nothing cannot create anything may be invalid, yet you provide no plausible explanation or theory in return. I'm not even asking for proof, just a plausible theory how out of literally nothing, we had the Big Bang.

Who said it that science needs one miracle and after that, they can explain just about anything? Sounds similar to the topic that shall not be discussed here, doesn't it?

A sticking point for me has always been the supposed singularity from which the cosmic expansion came to be. Furthermore, it is a "naked" singularity. A naked singularity is not permitted according to the “cosmic censorship hypothesis,” according to: Penrose, Roger (1969). "Gravitational Collapse: the Role of General Relativity". Nuovo Cimento. Rivista Serie. 1: 252.

So what process led to this assumption? The Hot Big Bang model.

What they did was extrapolate backwards using assumptions from universal expansion.

That is, the existence of this promordial singularity is not the most fundamental assumption in BB theory; it is the backward extrapolation of the universe's expansion to a singular state that forms this fundamental assumption.

I guess I should have defined extrapolation: "Extrapolation is defined as an estimation of a value based on extending the known series or factors beyond the area that is certainly known."

It is a mathematical tool used in various areas such as Psychology, Sociology, Statistics, Econometrics, Finance, and in the sciences to usually make assumptions about "future" trends.

Known data points are given to an algorithm to make those predictions. In the case of the BB, this extrapolation is done in reverse.

What is weird about the calculation of this primordial singularity is that certain assumptions themselves are used as data points for this backward extrapolation.

So one has to ask: How good is this backward extrapolation if most of the data points are assumed or unknown?

I think this shirt fits nicely.

But at the moment of this proposed bang, the laws would apply, at that very moment....... before this "time" the laws would not exist....... the effect would have no cause. Before this "time" time would not exist, and neither would speed, or physics for that matter.

Ever thought of the perspective on time, of a photon? I would think that the photon would have no perspective of time. I would think the photon would be able to see everything, that has ever been seen, all at the same time, and at the same time, be born, live and die,,,,in the same instant. Mind boggling.

And before the BB there would be no space as well, since according to GR space and time are closely related in the space-time continuum. In fact, GR would not apply before this event.

The historic time line here is interesting:

Einstein's Lambda factor was inserted to keep the universe static.

Hubble's findings suggested that due to his Redshift-Luminosity calculations, the universe was expanding.

Dark Matter was hypothesized to account for the hypothesized missing real matter in the universe.

Some observations suggested the expansion of the universe was accelerating due to the hypothesized Dark Energy.

Findings of late suggest the universe's acceleration is slowing down.

Conclusion: Cosmology is in a constant state of flux.

.is the state of flux also due to the pet hypothesesisisis, previously stated?

missing real matter

is this because the conclusion was made before the observation?

I understand the value of extrapolation, but it does sometimes, perhaps more times than not, lead in the wrong direction.
