TL;DR Summary
I have a few questions about Warp drives? I am a layman.
I watching this video and have a few questionsIs the warp shield the bending of space in the warp drive?

In a warp drive in order to speed you need a to feed in energy.

If you do not feed energy would the speed just be the speed of the ship?what is the warp shield made of? I mean is it man made or created by nature?Is the smaller the bubble the faster you go? How does this relate to Lentz's paper and my question?

Does Lentz's and Alcubierre's paper have the 3 criteria that Bobrick and Martire require to create the warpdrive?In Lentz's paper can the warp shield be created by nature or is it man made? In Lentz's and Alcubierre's papers can you accelerate faster then light?By shrinking the passenger area do you need less energy to go faster?

I am sorry to say there are no trustworthy papers supporting warp drives.
 
But what about lentz's work?

Videos are generally not good sources if you want to actually learn the physics. I would recommend picking some of the papers published on the subject (which you evidently are aware of since you refer to them in your post), reading them, and framing questions based on what you read. That will be a much better basis for PF discussion.

For example:

If you are interested in it, then read it, and pose questions here (in a new thread, since this one is going to be closed, as you will see shortly in a follow-up post from me) based on what you read.

This is a bit extreme. "Warp drives" are perfectly mathematically valid solutions of the Einstein Field Equations, and there are plenty of perfectly valid papers describing these solutions and exploring their mathematical properties. They are generally not considered physically realistic because they generally require some form of "exotic matter", or have other peculiar properties that are generally not considered to be possible to actually realize. But that is a much weaker statement than the one you are making.

Since the thread is not based on a valid reference, it is now closed. A new thread on this topic can be started if it has a valid reference as a basis for discussion.
 
From $$0 = \delta(g^{\alpha\mu}g_{\mu\nu}) = g^{\alpha\mu} \delta g_{\mu\nu} + g_{\mu\nu} \delta g^{\alpha\mu}$$ we have $$g^{\alpha\mu} \delta g_{\mu\nu} = -g_{\mu\nu} \delta g^{\alpha\mu} \,\, . $$ Multiply both sides by ##g_{\alpha\beta}## to get $$\delta g_{\beta\nu} = -g_{\alpha\beta} g_{\mu\nu} \delta g^{\alpha\mu} \qquad(*)$$ (This is Dirac's eq. (26.9) in "GTR".) On the other hand, the variation ##\delta g^{\alpha\mu} = \bar{g}^{\alpha\mu} - g^{\alpha\mu}## should be a tensor...
I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say near a black hole, and I draw a triangle on this paper and 'measure' the angles of the triangle, will they add to 180 degrees? How about if I'm looking at this paper outside of the (reasonable)...
