Sorry, what?

and by space-time warp: do you see it as you scooping sand on the beach? You think it is going to bring objects that are away closer to you?

thanks

More like a balloon. You are expanding and contracting the 'volume' of spacetime, not merely altering the 'shape', like the common illustration of the way gravity does.

Cool. How do you suggest contracting ( I assume) space-time?

Be honest.

I don't suggest any method of doing it whatsoever. I'm not trying to create a warp field. I don't have any idea how it would be done. That's why it's NASA working on it, not me.
I'm just explaining the basics of the Alcubierre warp theory.

Well actually the warp drive works much like riding a wave on a surf board. If you create a wave in space time and get to the top of the wave you get carried along. But you need negative energy to create this wave. The wave you create moves you through space time.

what's a broglie elastic deformation cycle?

according to it, mass causes space-time distorted to a degree. I meant to say if to move a vessel off the ground you would need to counter Earth overall gravity rate by creating even greater rate gravity 'well' immediately in front of the vessel. Meaning the vessel should fall into locally more abrupt gravity well that would go in front of it to create propulsion, no?)))

This is not the idea which is explained in the warp mechanics 101 link I posted in the 2nd post on page 139 which says:

The concept of operations as described by Alcubierre is that the spacecraft would depart the point of origin (e.g. earth) using some conventional propulsion system and travel a distance d, then bring the craft to a stop relative to the departure point. The field would be turned on and the craft would zip off to its stellar destination, never locally breaking the speed of light, but covering the distance in an arbitrarily short time period of time just the same. The field would be turned off a similar standoff distance from the destination, and the craft would finish the journey conventionally.

So warp drive has nothing to do with gravity in this scenario, though others have suggested some other possible applications related to gravity later, but it wasn't the original idea.

The idea of warp drive is to cover light years of space in as little time as possible, space which has very low levels of gravitational attraction from relatively distant objects. As Alcubierre envisioned it, the warp drive would have no role in escaping Earth's gravitational field.

Where did you come up with that? Give me some context. The first word looks like a misspelling of de Broglie, a famous Nobel prize-winning physicist. That phrase is mentioned in a dodgy looking anti-gravity patent where if they can't even spell the physicist's name, I don't have a lot of confidence in their other citations about his work. I'm not picking on you, but I am picking on the patent where I expect to see de Broglie, not just "Broglie". Actually the patent spells it both ways so it's very sloppy with spelling and probably also with physics.

a lot of words none which explained the origin of magnetic fields and the chem light thing was silly. it should be brighter inside the sun

another one skirting the origin of magnetic fields and why the sun spots are black

again, a lot of words and no answers

I wasn't skirting the origins of the magnetic field. I don't know it. So I didn't attempt to address it. And I did explain why sunspots appear dark, in comparison to the surrounding photosphere. Heliophysics is not my profession.

Saying I'm wrong and proving I'm wrong are to very different things and your welcome to try. What evidence do you have that fusion doesn't occur?

I must be getting psychic I told you in my post someone would argue.

I found the theory fascinating when I was younger, actually. But it doesn't seem to line up with observations very well...

But how do you contract a space-time?

First you need exotic matter. Where do you get exotic matter? Nobody knows, that's why it's speculative, and might be impossible. The NASA researcher leading the project says dark energy has similar properties so we can't say there's no such thing, but nobody has any idea how to gather up some dark energy (or exotic matter equivalent) and use it to propel a space ship, which again might be impossible.

And barring unforeseen circumstances like ripping apart space time.

Try at all we have probes and those probes told us to bury this idea. The only place it still lives is on the net for people who know little about science. To them it makes sense because they think they understand ekectricity.

a reply to: dragonridr

Yes, certainly the data we have gathered have put this theory to bed rather nicely, from a standpoint of possibility.
