Is it possible to build a light sabre just like those found in Star Wars? The key may be found inside of a crystal.

Dr. Michio Kaku tries to:

Enjoy!

It's impossible - and what he "builds" isn't a lightsber.

It's like asking "can someone build a corvette? Well here's an Amtrack Train that does the same thing..."

That, and old story is old.

He doesn't even "build" anything in that short 1:45 minute clip. He basically refutes the possibility of recreating a TRUE lighsaber by explaining the technicalities behind laser technology and how it works.
So you either TLDR the video and responded in ignorance or you're just a troll.

my favorite part of his idea is that he wants to use a magnetic field to contain the plasma blade.

ROFL imagine how funny the movies would have been if the light sabers had a strong magnetic field. Constantly getting stuck on eveyrthing metal.


Yeah thats not even close to a light saber.

i have always believed that a REAL light saber would emit a ridiculous amount of radiation

What if.... We put a mini black hole in the handle.... and it would keep the light from going too far out. But it wouldn't solidify it. One more problem solved for the lightsaber recreation.

No matter what, problems with the laser itself aside, the one HUGE problem when trying to even conceive a real light saber, is making the laser itself stop.

He forgot the force, which makes it plausible, he's just not strong enough with the force.

The key to building a Lightsaber is not found in a crystal, nor is it known by Kaku or any mere mortal man. It is known by the diety known only as Battlebug, and I quote... "can you make sword in box light sword so sword come out when opened? then if sword is back after sword, use light saber on box, and saber will be boxed after sword is out."

Even though some of these is not possible..below is a reasonable theory.

The light is basicly a laser, we can already do a laser that goes strait with no difficulty.
You combine a couple different colored lasers the same direction so you form a visible light.

You have some type of device that adds a lot of additional weight/density that piggybacks to the laser light particals themselves. ( Kinda of like some sort of fuel that releases energy, its unstable so does not stay in its compressed form to the light particles )

The weight of the fuel attached to the light beam gives it its solid density and the release basicly releases heat which causes a burn type wound...very hot..vaporizing everything it touches.

As this fuel cell decays seperating it from the light beam it speeds up the beam itself ( eventually faster then the speed of light. This is how you achieve warp speeds)

The full process takes about one meter of space to fully decay and remove itself. This is where the beam would lose its solid density, and also not exist as visible light anymore because it went beyond the speed of visible light.
