Propulsion Engineer Answered

I want to design new propulsion systems that don't need to use combustion, what should I major in, I was thinking of majoring  in Aerospace engineering and minoring in Electrical engineering.
Any suggestions?

p.s. the propulsion includes, but is not limited to: anti-gravity/warp-drives  (Which physics says is plausible)

Could you clarify what you meant by:
(Which physics says is plausible)
?

I can read this as "Which physics say this is plausible?" or "I know what I'm talking about with regard to anti-gravity/warp-drives because I heard of some 'physics' which sounded to me like it is plausible."

They say it may be possible (aka plausible) not that they are science fact
http://www.nasa.gov/centers/glenn/technology/warp/antistat.html
Anti matter is also included

A nice diagram there, but looking at that - what were you hoping for in response to this question?

If you would read the description, it says that this is the stage that we know what we know, and know what we don't, and that it takes MORE RESEARCH in order to move into the science section.
Now what should I study in college to make that possible?

The answer is obvious: science
Do something hardcore like physics or chemistry at a good place,

Subjects like that underpin things like Aerospace engineering and Electrical engineering.

Now a bigger question.. What school should i study at?
My mom nows an electrical engineer who said he applied to Georgia Tech, University of Illinois, University of Michigan Ann Arbor, NYU-Poly Tech, Carnegie, Cornell, and a few others I forget. Any of those good? I did some research and most of them are in the top 10 for engineering, and my grades should be good enough to get me in.

Choose somewhere good, but recognise that beyond that it's what you do that matters - where you go isn't everything.

Please cite your sources, from valid peer-reviewed journal publications, for your claims of "plausible."

"Antigravity" is most assuredly not considered "plausible" in general relativity.

The Alcubierre metric is consistent with general relativity, but is not a "plausible" warp drive because it is a stationary solution. That is, there is no plausible transformation between a non-Alcubierre metric and an Alcubierre state (in Alcubierre's original paper, the bubble "just happens"). Put another way, there is no plausible way, consistent with general relativity, by which such a "warp drive" could either be turned on or turned off.

Does that statement imply that dynamic solutions are forbidden, under GR ?

No, not at all! Just that Alcubierre's bubble isn't time-varying (and hence, can't be used as a "drive" system).

Other authors have come up with mechanisms by which an Alcubierre bubble can be formed in an otherwise flat spacetime, but those mechanisms require extremely large amounts of "exotic matter" (i.e., stuff with negative pressure, negative energy, or both) and/or tachyons.

exotic matter sounds interesting... was something like this proven to exist and can you tell me where i can find more information?

Oh, no. Exotic matter is what the theorists invoke when they need to solve the Einstein equations with a prima facie impossible stress-energy tensor :-)

....and then they can start looking for it.....
MACHOS, WIMPS, Dark Matter - all hand-waving from the theoreticians.
Discuss.

Hand-waving yes, but unfortunately, both of those candidates for dark matter are perfectly ordinary (i.e., positive pressure, positive energy density) matter.

MACHOs have been seen many times (through microlensing events), but not at a high enough rate to explain galactic rotation curves. They are nothing more than "free" planets, or brown dwarfs, or black holes.

WIMPs, like axions, are a sensible (some would argue necessary) extension to the standard model (WIMPs are generally assumed to be the lightest supersymmetric particle, while axions are necessary to solve the strong CP "paradox").

Discuss? So what do YOU think Dark matter is? Neutrinos? Baryons? Do you like the CDM model ? ;-)

Engineers work within the realm of well defined physics, plausible doesn't cut it. If you want to deal with plausible, go into theoretical physics.

. Without getting into the plausibility issue, I'd suggest majoring in Physics (how to do it) with an Electrical (how to control it) minor. It sounds like your system would be used for interplanetary travel, so Aeronautics won't apply (there's no aero in spaceo).
. But what you are really after is an education. You want to learn how to hypothesize, design experiments, collect data, interpret your data, &c. Just about any Engineering degree should teach you that.

Yea it does touch in the realm of interstellar, (BTW thanks for giving the only legit response to the question) but it can also be applied to earth travel,such as for cargo transport, public transportation like airliners, and emergency services such as fire and rescue, or ambulances, things that need to go faster, where ground travel is at it's limits.
