From what?
The big bang was the creation and expansion OF space.
To simply say "We do not know" is no more admitting defeat than someone who invokes a plot twisting Deus Ex Machina to solve problems they never really bothered to try and solve.
Why? Open Question
How long id it take heating to cause it to explode? : A question that relies on too many assumptions about the cause to be truly a relevant question.

It was stated that when you enter space, the light from Suns and stars can't be seen. You can see the Earth and planets and other solid objects though.
This solves several problems.
Why is starlight still so intense, after travelling over such a far distance? It may be that in space, light can only be perceived when striking something. With nothing to bounce off of, light can't be seen emanating from stars.
This also implies that its the lensing effect of a planet's atmosphere that reconstitutes light over a distance. This model radically changes how we perceive light and effects over distance.
This would mean that the Sun and starlight we see may not actually be old. There is no light-year. There is no time delay. Does the very vacuum of space have strange effects on light? Only through a prism can light be perceived.
I also believe that our Sun is exothermically powered. It actually draws from an unlimited supply of Zero-point vacuum energy. This explains why the Sun has DARK spots. If powered internally, light would always appear from within. Our Sun is hollow.

It refers to vaccuum energy, something which you said doesn't exist. So to answer your question, from my perspective where vacuum energy exists and s not "nothing" then no, the use of vacuum energy is not "nothing".

Does the Lamb Shift incorporate 'nothing' into its equations/calculations?
From your perspective, I don't know. That's why I asked how you made sense out of it while denying vacuum energy exists.
Yes I have qualms about the terms and you should to. The term vacuum is suppose to signify nothing. What exists throughout space? Fields right, Em and gravity (and blah blah blah maaaaybe higgs) and the quantum particle fields, which are really the EM field right, because they can turn completely into radiation?
Ok so why say, a term originally used to refer to the lack of all energy, 'vacuum', to then say that it is the 'lack of all energy' (Nothing), that is now responsible for 'the creation of energy', and we will call this vacuum energy. IT IS ABSURD and DISHONEST, and other bad things.
So more likely, what they call or refer to as vacuum energy, is energy from, one or many or all of the fields that exist throughout space.
So I am saying, if energy is detected, energy exists. I am saying it is 'schemy', seemingly alteriorly motivated, to refer to it as (a proper translation) 'the energy which comes from nothingness'.

Well, the properties you describe are properties of space. The big bang was the creation and expansion OF space. This is commonly misunderstood as we have lots of our own ideas of how things explode and expand IN space, but the very idea of space itself expanding is a little alien to most.
Before the big bang, well given that space didn't actually exist, thus everything with spacial properties didn't exist either.
No it was not the creation of space. We just went over this, space is energy, energy cannot be created. And if now you are referring to space as nothingness, nothingness can also not be created.
The idea of space expanding is only alien to most because most were taught or assumed or intuited that the black stuff between the stars and big rocks was nothingness. It is not so alien when it is known that that black stuff is an energetic medium which is interconnected to all other energetic/material phenomenon.

Actually Vacuum implies a lack of particles. A volume that is devoid of matter. fields are just fine.
Ok so it should be no surprise that 'Vacuum fluctuations' and ' vacuum energy' exist, because fields exist all throughout space, and thats what everything is made of and connected to, and it is all moving, and carrying forces, so it would be strange if the fundamental most micro constituents of the everythingness did not vibrate.
So, is vacuum energy, a result of EM field and gravity field and higgs field and quark field and electron field interacting? Or in different cases its different combinations of those to different degrees? And its all just lumped under the name Vacuum energy?

Why? Open Question
How long id it take heating to cause it to explode? : A question that relies on too many assumptions about the cause to be truly a relevant question.
Is heating still considered to be the cause? If not, are there other suspects?
If it is believed to be from heating I would consider the time to be extremely relevant myself. Not the actual amount of time but rather that there would be a time period at all. I can't conceive a heating process that would be infinite in duration coming to an end. If not infinitely old then at what point in time and why would it begin?
Im not sure heating was ever considered the cause it was always an effect.
Foe example the uniformity of temperature in the universe cannot be explained by the big bang this is why QM takes over and explains it using inflation which does account for the uniformity.
The Heisenberg Uncertainty Principle states that in a quantum system the position and momentum of objects, and their energy at the time of observation cannot be known exactly. Heres the math for the equation dp*dx >= h_bar/r and dEdt >=h_bar/2 .basically dp = uncertainty in momentum, dx = uncertainty in position, dE = uncertainty in energy and dt = uncertainty in time. h_bar is planck's constant over 2*pi which is on the order of 10^-34 J-s.

If that's the case I wish someone would have told my teachers.

And that leads to the questions; Inflation of what and why?

Ok i was trying to figure out a good way to explain this but it requires you to understand space-time. This has its own properties for example energy can be swapped for time. Space can be bent it can also be created and finally it can never be truly empty. Quantum fluctuations (QF) occur in the vacuum, which is the absence of matter and energy but still a part of space-time. "Nothing" would exclude space-time as a structure as well. The Heisenberg Uncertainty Principle states that in a quantum system the position and momentum of objects, and their energy at the time of observation cannot be known exactly. Heres the math for the equation dp*dx >= h_bar/r and dEdt >=h_bar/2 .basically dp = uncertainty in momentum, dx = uncertainty in position, dE = uncertainty in energy and dt = uncertainty in time. h_bar is planck's constant over 2*pi which is on the order of 10^-34 J-s.
Now the universe is governed by probabilities for example the the fluctuation that created the universe it happened and didnt happen. But to us in the universe were in all that matters is the one that did happen. Everything is governed by probability which is represented as waves, and thus it becomes hard to localize things or observe more than one thing.
Now let me touch on vacuum energy think of it this way instead. Think of it as a dividing line between positive energy states (our space-time) and negative energy states. Remember we cant have 0 energy but in order for space to seem like it it plays a game energy will rise above our dividing line then go below it this creates the illusion of zero energy. So we have a particle that moves into (our spacetime) then goes back into a negative energy state this is caused by energy and its lower limit the entire universe is always trying to reach its lowest energy state which is zero. Unfortunately we know this cant happen because energy just cant be destroyed.Now energy is waves they have a high point and a low point when this energy reaches its high point we have a particle remember einstein's equation energy and mass are the same. When it reaches its low point the particle no longer exists this isnt fluctuations in a specific field this is energy . Like a photon can be a wave or a particle its called duality energy is the same way its a wave but when observed we can see a particle but only when the energy is high enough. Does that make sense??

Ok so now that we know the term vacuum, no longer is what we thought it was (when we thought it was nothing), now what is it said vacuum is? Is it not critically known and understood that when one uses the term 'vacuum', they are referring to Gravity field, EM field, Quark field, Electron field, and Higgs field?
That question does not logically follow from the statement:
I ask... energy fluctuation where and when if there was no space
The MS science will tell you the space itself is what inflated

Physics redefined a vacuum as the lowest possible energy state of a given area. Simple way to be all inclusive yet brief.

I did ask what inflated and why but that is in the context of the point that the big bang didn't/may not have(?) happened.
