The lightsaber possibly a reality?
But here is what I believe we must do to achieve a goal of building a lightsaber. I believe we could accomplish this goal by taking a simple plasma cutter and altering it to where it burns less gas and removing the big bulky tank and replacing it with sevral smaller tanks that are pressure treated on or in the saber its self which will reduce weight drasticly. I also believe we need to bond the protons in the "blade" on the saber together to form the solid blade as used in the fiction. Another thing we would have to do is mount the electrical components of the cutter on to the saber. These modifications will allow for a longer lasting saber. A saber that can be hand held. A saber with a solid "blade". After lot more research I say that we could have a saber that would ultimately work.
(Doubt me if you want but don't make fun of me because I have done my research lasers go on forever so they won't work light does the same so a proton bounded plasma blade is the only relevant answer I can find on how to make a light saber hope you enjoyed and comment what you think)

But in the real world they do magnetic confinement fields for plasma to create fusion, wikipedia
Assuming a power source could be miniaturized sufficiently to run something like that, I'm really not sure I'd want anyone to have one! I prefer available protection measures to supersede available weapon capabilities generally speaking, so I'm not sure I can afford magnetic shielding on my car and house just yet

But you'd have to explain your idea in more detail for me to understand it.

Looks vaguely/sorta/not really like this
I have no idea how star wars blaster bolts could theoretically work, but a lightsaber could turn smaller slow-moving projectiles into metal mists. That might not be a good thing though.. If you have plasma bolts with their own magnetic fields (a la Adder) interacting with the lightsaber, some wacky stuff would probably happen that could either extinguish the blade or short/burn the electronics out.

I have a few questions regarding this section. 1) If they should serve only as a symbol then why bother with the crazy science of making them function? If they should not be used for the possibility of combat why make them combat worthy? 2) Is there not something that already exists which might serve the same symbolic purpose? 3) Who would decide who is "in tune with the Force" enough to wield such a weapon?
All those questions aside, if someone actually does manage to make a workable, portable lightsaber put it on my Christmas list. :woohoo:

So this is a fun discussion, and while my background is not Physics, I present to you Michio Kaku, whose background is. He did a series on YouTube on building a lightsaber, and I have linked to it here.
How to build a Lightsaber Playlist
It has been a while since I watched it, but I believe that the simple answer is that we cannot build one that looks or acts like those of the Star Wars universe with our current technology and understanding pf the laws of physics, but the Star Wars universe has the Force, so there it my be possible.
It is a series of videos.

Citation, please.student of the force wrote: ... researchers ah [sic] harvard [sic] and Yale have actually made light solid by bonding protons together...
Plasma is material. It can and does already interact with itself and its environment, mostly by haemorrhaging energy in amounts so great as to illuminate the sky in case of lightning or a room in case of a candle flame. It doesn't take making light solid (what ever that even means) to get interaction. But I'm pretty sure you can't get two plasma streams to collide so as to stop the emitters from moving on.... based off the research they have conducted I believe it is possible to do the same and get the "blades" to interact with one another.
So anyway, you were saying something abound bonding protons together to form what I assume is something solid-like. Now I'm no expert on matters of electrodynamics (in fact, I'm failing it a second time right now), but it would seem to me that a few rather basic things like the Coulomb force would be quite an obstacle there. I'll be most grateful if you could link us the paper you read on this research...
