I want a sculpture that reflects no light. It'd look like a massive gap in space, like an eerie silhouette that doesn't quite seem corporeal, in a sense.
So, is it we who are going to go with this whole Protoss/Eldar like technology...?

Not too much of an expert on this, but shouldn't that mean you wouldn't be able to see it at all?

Sort of like invisibility, maybe?
I think if that's the case, you can see it. Its just 100% black. Black doesn't reflect any light, but you can still see it if I'm correct, though is there such thing as 100% black?
amazing. This is just incredible.
Does this mean you could pull light in, therefore creating "black" areas where no light can escape?

There's a name for that
It's called "Black"

No because just like black holes you know they are there because of the surrounding.

It would just be black. That's what black/darkness is; absence of reflected light. You wouldn't see any details in the sculpture, just its silhouette against the non-black background.

build a long hall way with faint lights on the end and put that on the end. Make it just barely human in shape.
do it

Black objects still have discernable lines within the outline of the object itself, and depending on the material, might have reflective areas. A totally non-reflective 3D object might just look 'black' the way that we think of it from a fixed perspective, but if you moved around it, it would seem to collapse into itself and distort outwards all at once. Just a thought, doubt something like that could be achieved, but it'd be neat as hell.

A black hole is 100% black, as any light that would be able to reflect it gets absorbed by the intense gravitational pull.

Think we're more following the Tau'ri from stargate, which is another name for the humans of earth. So the stargate program is real...

There are already "blacker than your usual black" materials. Obviously, they never will be "perfectly non-reflective", but I think you could already get some stuff that could get close to what you want. Not sure what exactly would it have to be and how much would it cost, tho.

[quote]Scientists have fashioned what may be the blackest material in the universe: a sheet of carbon nanotubes that captures nearly every last photon of every wavelength of light.
The substance absorbs between 97 percent and 99 percent of wavelengths that can be directly measured or extrapolated. It’s the closest that scientists have yet come to a black body, a theorized state of perfect absorption whose closest analogue is believed to be the opening of a deep hole.
The material, described Monday by Japanese nanotechnologists in the Proceedings of the National Academy of Sciences, is made from a flat array of vertically-aligned, single-walled carbon nanotubes. Photons that aren’t immediately absorbed by a single nanotube deflect off and are absorbed by its neighbors. [/quote]

Looks pretty black to me.
Couldn't this be used to make true invisibility as well?
You make the photons "bend" around the object instead of hitting it.
Christmas tree lights are bad enough when one goes out. Now it's on a nano scale.

IIRC (and this is just a vague recollection here, I'm probably wrong) that wouldn't make you invisible, it would just make everything affected pitch-black. It'd be good for looking scary and for doing shit at night, but it'd far cheaper to just wear black clothes.

That aside, I want a stealth cloak that much more badly now.
This shit blows my mind

Nah it would work like genuine invisibility, the only downside would be that anyone using the cloak or machine or whatever wouldn't be able to see anything while it's active unless you generated light inside the field, which would probably nullify the effect since the light would probably pass through the cloak rather easily.

I would love to become a shadow.

Or make it a skintight suit with eye-holes. Floating Eyes!

I want a flashlight radiating shadows instead of light

Doesn't work like that, we've been experimenting with meta materials that bend light around an object so the light would never hit your eyes so you'd be blind whilst it's active, at least for a particular area of the EM spectrum.
We're already testing it on tanks and the MoD have apparently said that it worked flawlessly and there should be actual battlefield applications within a few years. Managed to find a picture of it so here you go:

It's like, how much more black could this be? And the answer is... None. None more black.
