Is "alien technology" only Science Fiction?
Can there not physically be something thin, light, and bulletproof?
Why have we not discovered these materials yet? What would it take?

Armor of a given thickness can be only "so" bulletproof. The impact is breaking molecular bonds. On a macroscopic scale, breaking the material. And there's only so much force a bond can absorb without snapping.
Kevlar armor spreads the force out so it doesn't do as much damage. You want to avoid force concentrations. Every struggle with a potato chip bag? Resists your best efforts. But once you cut a tiny notch in the surface, it rips easily. Because you're only dealing with a few bonds at a time.
You want armor that's stop a howitzer? You'll need something thicker. And maybe so heavy you can't lug it without powered-armor (like in Heinlein).
Even if you dissipate the energy safely, nothing you can do about the momentum. A shell will knock you off your feet and the concussion may kill you even if your armor is unbroken.
Jason Perez
could the armor somehow autorepair itself on the molecular level?
Jonathan Smith
Yeah dude let's just weave some unicorn hair into it I fucking love science!!!!
Thomas Adams
There are such materials.
Little sealed capsules of superglue. If material broken, the gunk oozes out.

It's not instantaneous, any more than your cuts vanish in seconds.

>Can there not physically be something thin, light, and bulletproof?
These are all wishy-washy terms. Yes, something physically can be all those things. How thin does it take to be "thin" to you? How light to be light? What caliber has to be stopped to be properly "bulletproof", and at what velocity? Are we talking me tossing a bullet at you? 22lr? 9mm?
If we take reasonable measurements for each of these, we already have thin, light, bulletproof stuff. Kevlar.
The current new meme is carbon nanotubes though and that's what you want to talk about.
Blake Hughes
Of course it could. It's called an epidermis and you've already got one.
Josiah Sullivan
No, we have reached the pinnacle of technology and science. Everything you see today is all there will ever be.
Samuel Howard
Agreed. Scientific discovery is beginning to plateau. 500 years from now., shit will pretty much be the same except more decay in the system.
Alexander Campbell
Agreed. You would need material that can resist tearing at the molecular level for it to stay in one piece. Currently, a number of militaries use ceramic plates layered with plastics, but they are a one-time use that shatter after the first hit and can still cut the wearer with the fragments. Even then, the wearer is still knocked over when hit by momentum of a single 0.50 cal. bullet.

Not sure if 0.50 cal at 1:32, but he ain't just walking it off.
>Powered-armor (like in Heinlein)
Good book. Definitely presented in a much more badass way than any of the film adaptations.
If you are going for thin, light, bulletproof, you might as well just work on camo and try your best to not get shot.
Daniel Moore
A human plateau. Automation and increased specialisation will go beyond it.

A navy seal would NEVER fit into that skinny as hell suit.
Alexander Gray
No it won't. It's only strong in one direction, like nanotubes. You can pull it as hard as you like, but it's shit against compressive forces.
Carter Cooper
So flip it inside out?
Ethan Rogers
A good exo suit would need a seriously lanky person inside so that they would actually be able to move normally once you fatten them up. There is a real limitation when you have to use the existing joints of a human body as the rotation points while adding material around them. Like wearing thick gloves but worse.
Landon Bell
>It's not instantaneous,
The problem is the impact even of the bullet is NEAR instantaneous, so maybe your nanomachines son armor repairs the damage, but not until the bullet has already done its damage to you.
Parker Cook
We have discovered these materials and you use these materials everyday. It's just you don't use them to space colony or to kill aliens, so you don't care.

Go whore out your R&D to someone else Darpa faggot.

Regardless of your moronically incorrect opinion, they realised that the nanosuit 1 could not actually fit a person inside it, and hence bulked up the nanosuit 2. I don't much like the metal codpiece, though. The 2nd suit needs some webbing for equipment to offset the appearance of a body builder in a G-string. The multiplayer suits had this, while the single player suit was left bare.
Ethan Adams
Carbon nanotubes, metamaterials, soft robotics, or things like superconductivity...
There's absolutely nothing fiction about it. It's just new and expensive as fuck right now. If you had a dozen years, an unlimited budget and the best minds and engineers on the planet working on it, you could already create a near invisible suit of near indestructible armor granting superhuman strength (and probably give you cancer while it was at it).
There's just no fucking point in doing it.
Eli Walker
Yes because composite and multilayer materials and armor are a new thing? Where do you live, in the stone age?
I mean using a combination of materials to complement each other is literally a technique that's been used for fucking millennia. Steel, plywood, even that kevlar he just commented on? There isn't a single application of kevlar out there that isn't some kind of composite.
How can you even know about graphene without also knowing its obvious applications come from merging it with nanotubes and other materials to give extreme strength and durability in all directions?
Nolan Gonzalez
Please, if you really knew graphine, then you'd know its not cut out for bullet resistance.
Jaxson Ross
Christ, I'm so tired with you people today. See the gif? The ball's the point, the girl's you. Wait for the catch.
Jacob Jones
>If you had a dozen years, an unlimited budget and the best minds and engineers
This exists, its called US military RND. If you knew literally anything about scientific principles or the state of materials science you would realize that no we cannot already create an ironman suit.
Jack Rodriguez
>Why have we not discovered these materials yet?
We have, it's just really difficult for us to fabricate
sciencemag.org
There's other really useful properties, too bad it's also retardedly expensive to produce
John Young
Not fast enough to stop a bullet. And it would probably be easier to get a new one after you get shot, than build some high tech crap.
Brody Gonzalez
>if you really knew graphine
...then you would know it's graphene.
