Um. No. Everything we 'know' about subspace came from Gene Roddenberry. Its StarTrek Physics. It has--repeat after me--No Basis In Real World Physics.

you sure about that, from what ive been hearing (non st related) theres been a lot of theorizing about subspace and wormholes.

Wormholes? Perhaps. Subspace? Not from any scientific circles I've ever heard of. A quick search for 'subspace physics' reveals that pretty much ever thing written on the subject is a rationalization of 'Trek Physics' or stuff about the game 'Subspace'.

want to see any serious stuff about FTL travel and alike?http://www.grc.nasa.gov/WWW/PAO/warp.htm

[KillMeNow]

the term warp drive is a str trek term however due toa  similarity with certain theory of late its beent aken up by the real scietific comunity to explain possible methods od traveling faster than light by folding space time etc etc etc - but its folding this space time not some other dimesions so there is no subspace involved at all its all in real space we just  move the space time contiunium to where we want to be so - while we are limited to less than lightspeed the fabric of the universe isn't

negative mass isn't needed for warp drive theorys - just a anitigravitational field i did some looking into this - but it does have to be anti gravity not a gravity negating device i need ot push things away push all things away witha  gravitation field now if it can be achieved without negamtive mass then we dont need the negative mass but its though of as the most  likely candidate for creatinga  genuine antigrav field but perahps one day when we understand gravity better we can do ti without it

Gravity can be blocked using high-speed spinning super-conductor discs.

[KillMeNow]

anyway venom that site it hasn't been updated in years and i mean it litterally at least 4 probally longer well last tiem i check anyway unless its been updated in the alst month but the info on there is still interesting and acurate for the most part

[Unknown Target]

Actually, he's right McHale(), there has been a lot of theorizing on it.

[KillMeNow]

that gravity blocking device is still under scutity the russian who did it wellllllllllllllllllllllll........................... i dont know nasa tried it and it didn't work he said it was cause you need a verys specific forula for some cehmeicals or something but hes supposedly working with nasa now to re evaluate the tech if it works great but my gut tells me the guy was just trying to get into the papers
if its true i herby profusely apoligise to the man and declare hima  genius of huge proprtions

[Zeronet]

It doesnt block gravity....

[wEvil]

the NASA scientists had marginal success - it did actually work, but just not as well..

something like .01% of this russian guys' supposed results.

I wonde what would happen if you stacked a number of such disks on top of one another?

the GS on the Havok origionally used something like this to negate "local" gravity...but then I opted for braneworld control instead cause nobody understands it well enough to put up a convincing argument against is

How not? It was specifically stated that it'd 'inhibit gravitational field effects'.

[wEvil]

it NEGATES gravity, doesnt block it.

theres a difference.  i think.



either way...a conclusive..err...conclusion to experiment like this could be very interesting for graviton theory

[Mr. Vega]

The only FTL theory I that can be anywhere close to possible is B5 hyperspace.

There, hyperspace is the center of the universe, and the galaxies are on the outside of the universe (expanding universe). You can get to places faster in you take hyperspace because of the tighter turn in the universe. Its like how you can make a turn on the inside portion of a track faster than on the outside portion of a track. Only thing it can't explain is how you can suddenly get to hyperspace from normal space.

[an0n]

an0n's basics of sci-fi physics
Subspace - Invented my Gene Roddenberry to explain Enterprise FTL travel. Subspace is an energy plane which underpins all space and time throughout the universe. It affects and can be affected by things in our realm. Distance and time in subspace are non-existent and non-linear respectively.

Hyperspace - And artificial conduit or natural plane created to allow FTL travel or an energy plane where time and space are much the same as in our realm with the exception that travel through hyperspace equates to a much larger distance in our space. In certain sci-fi (Stargate) venturing into such a space without adequate protection (such as being inside a ship) from the temporal and kinetic would be lethal due to the sheer force exerted by the forced formation of a hyperspace realm.

[Zeronet]

Blocking is not a good term to use, its misleading.

[mikhael]

Gravity negation and Gravity blocking are as yet, not proven. Whereas the Russian 'physicist' claims results, no one has been able to make his idea work using anything remotely resembling the methods he says he used. It is, I am afraid, Cold Fusion II: The Son of Fusion.

Venom's site is probably the most useful thing contributed to this conversation, since it discusses, rationally, theories of efficient propulsion in space. Some of these theories are FTL in nature. It does, however, gloss over several things, like the ramifications of using such effects as the Alcubierre 'warp' theory.

KMN: every plausible faster than light propulsion theory put forth by a credible scientist with a solid grounding in physics has required 'negative mass' or 'negative energy' (interchangeable, of course) to produce important effect: FTL transit. Even most most theories involving the use of wormholes require the use of negative energy/mass to open and maintain the tunnel.

BTW, about that site being out of date?

Actually Alcubière's theory is rather Space Folding IMHO.
Funny how french takes a good place in FTL travel: Alcubièrre, Lagrange, her... did I just said that?

Oh, I hate to hurt you like this, Venom, but its Miguel Alcubierre-Moya, and he's Mexican by birth.

Alcubierre's effect is not space folding. It is the induction of a controlled compressive effect on the leading edge coupled with a expansive effect on the trailing edge of the field. This is not 'space-folding' so much as it is a local-slope induction.

[CP5670]

I think that the hyperspace theory might have some credit to it as it would properly explain the quantum entanglement phenomenon; basically if it was possible to leave the fourth dimension and exist in only three, velocity as a function of time would be meaningless (effectively eliminating the c limit) and all actions would take place simultaneously.

Also, that site venom posted has a bunch of useful information on this topic.

Lagrange

This guy was cool; he was one of the two creators of my favorite subject in math.

If time is non-linear, then how do people come out of subspace _after_ they went in? or is this a stupid question?
