Solar flares and what must be said about them.

Here's a clue for you.
Matt black would absorb all colour wavelengths because it cannot reflect. Fair enough?
Ok, now you know that this is what's percieved by use mere mortals, as space or the universe.
So where does the inner transparent perspex come into the equation, do you think?

Ah, right.  So the transparent layer is meant to closely approximate your "perfectly reflective" ice mirror?  How does that work again?  You are claiming the earth is covered by one giant mirror dome that reflects everything, yet when you build your model you will use a transparent material that reflects nothing?

This isn't making much sense.

You really need to get a grip on this stuff because pretending to know will just baffle your brains to hell. 

I don't pretend to know how your bullshit works, that's why I'm trying to get you to explain yourself properly.

Do you know you cannot see light unless it reflect off something? If not, I can't help you.

I'm not sure what that statement is in aid of.

Let's try again: which part of the model you are building is meant to represent the perfectly reflective ice dome?

the inner clear perspex will be mimicking the ice dome against an evacuation of air inbetween the transparent perspex and the outer matt black coated fibreglass dome that will be mimicking the vacuum of what people believe the universe is.
The inner sun will then reflect it's light waves off of the transparent perspex against the blackness of the outer dome, allowing for a reflective surface.

It won't obviously be a perfect mimic but it will give me a very good indication as to how close this model can be to reality.
I can't arrogantly say it will be a full on working model in its entirety but that's why there's variations in how I do it, which I estimate will take me a year to fine tune all the different experiments I make using it.

The project up to this point has cost me just under £7,000 with an estimated 3 to 4,000 still to spend to get it all in perspective.

LOL.  Do you know what the words "reflect" and "transparent" mean?

Yes, what's the problem? can't you grasp what would happen in what I've explained to you?

Let me try and help you out.
Imagine your window in your home. It's transparent isn't it?
Now imagine night time  with no street light on except your inner light in your room.
What can you see out of that transparent window?

Take your time on this.

You do get partial reflections off transparent media like water, glass, and plastic. Lens makers go to great lengths to minimize reflections, but they can't be eliminated entirely.

To sceptimatic, I respectfully suggest you not try to evacuate the space between your inner and outer domes - at least not at first. Any loss in fidelity will be minute - in fact, it might be better if you just painted the outside (convex side) of your inner dome flat black so you don't get a second reflection off that surface. Evacuating the space behind it (if even possible, which is doubtful) will make those reflections (slightly) worse.

Getting a structure of that size made of those materials to hold even a partial vacuum will be a difficult task. To keep it from collapsing if it could be evacuated would be monumental. Do you realize how much force your domes must withstand? A disk 12 feet in diameter has an area of 113 square feet, or 16,286 square inches. If you reduce the pressure between two disks this size by as little as 5 psi, that's 81,430 pounds of force pushing each side toward the other. That's the best case. If they're domes, the areas (and, thus the force) will be even greater; a hemisphere 12 ft in diameter has an area twice this. Never mind, you don't believe in math. Carry on! Do please keep us apprised of the progress, and don't spend too much valuable time trying to evacuate the space between the domes - I await your results.

I await your results.

I wouldn't hold your breath....

I'm well aware of what can be evacuated from it. Like I said it's only an evacuation of some pressure  but it's enough to act like a thermos flask which I need to keep out the effects of external temperatures causing problems.

When you see the final results you will slap yourself for believing in a silly globe model, I assure you of that.

Come back when you have something to show.

Excellent advice!  That means sceptimatic will never return (yaaay!), simply because he hasn't—and never will have—"something to show".  This totally imaginary model that he's building in his tiny brain doesn't actually exist in the real world.  If it did, he would've posted a couple of photographs of it by now as evidence that he was working on it, and to show us its progress.

I can guarantee that we'll never see even one single image of his "model" on this forum.  You can't take a photo of something that doesn't exist LOL.

And again I've called his bluff—as I've done several times previously.  And if he wants to call me out on this, then the answer's obvious... post a couple of photos.
