I pretty much followed and agreed with most of our post until you got to the Casimir effect. I know and understand that the Casimir effect is, but I don't understand why you said: "The closest thing we have to this is the Casimir effect." I read the link you posted and that makes sense but I didn't see anything in there about how the Casimir effect might be used to prevent a wormhole from collapsing?

Unfortunately wormholes are very unstable. Kip Thorne proposed using a form of exotic matter that bends spacetime differently than normal matter to keep wormholes from collapsing. The closest thing we have to this is the Casimir effect.
Here is a link....

You sure are making a lot of posts for someone who is banned... LMAO is right!

Why is that a problem? As long as you can only travel forward in time (relative to other inertial frames of reference) you can't go back and kill your grandfather, or perform any of the other backwards time-travel paradoxes, right?

Of course, the problem with Einstein's physics is that they lead to the potential for time-travel.

Casimir realised that between two plates, only those virtual photons whose wavelengths fit a whole number of times into the gap should be counted when calculating the vacuum energy. The energy density decreases as the plates are moved closer, which implies that there is a small force drawing them together.
Nobody knows if the Alcubierre drive is possible or not, it's very speculative. But it allows you to travel faster than the speed of light on a cosmic scale without traveling faster than the speed of light locally, so if it were possible, it might not tear apart human tissue.

How is any of this possible? I wouldnt know how anyone anywhere at anytime would be able to get mass to travel at the speed of light or faster. Even if by some way human kind could develop the technology, how would this be possible for humans? A human would not be able to travel at this speed as it would damage tissues, or damage the body at even an atomic/molecular level. Would it not?
I don't know, it seems to me like the reason the wormhole is unstable is because it pinches off too quickly. Creating negative pressure inside the wormhole (as in attracting the plates with the Casimir effect) seems like it would only make the wormhole pinch off that much more quickly, would it not? It seems like you need something to keep the wormhole open, not pinch it shut.

Decreasing the energy density enough to allow for the energy density to become negative. I.e. equal to applying negative pressure inside the wormhole.

Exactly! That's how you keep it from collapsing!

With the negative energy density it allows it to NOT attract itself.(It will stay in it's original shape.)Allowing things to go through without the wormhole collapsing.

Thus, the mirrors will attract each other, just as two objects held together by a stretched spring will move together as the energy stored in the spring decreases.

Now, look at what you said about the Casimir effect:

So it seems to me like you're contradicting yourself or else I'm misunderstanding you. You say we want it to NOT attract itself to avoid collapse of the wormhole (which is correct and I agree), then you give an example of the Casimir effect where the mirrors attract each other, which seems like the opposite of what you want to happen. What am I missing?
At this point it quickly becomes evident that either
A. Our understanding of physics is fundamentally wrong.
B. Light is not the constant we once believed it to be.
So it will tend to collapse at the throat. and you're suggesting the way to prevent this collapse is by putting mirrors there at the throat that are attracted to each other? Won't the attractive force between the mirrors simply accelerate the collapse? You're trying to keep it open, not pull it shut.

You could just keep both of them at the mouths of the wormhole or preferably at the throat of the wormhole because that is where it will tend to collapse.
