Here's a thought for you OP..

If you're in a room that appears to be pitch black to the point you can't see your hand an inch in front of your face, but the room is actually brightly lit with infrared light, are you really in a dark room?

So objects outside the event horizon experience no gravitational pull from the black hole? I don't think that's right.
Maybe gravitons only travel one way. Mass outside the black hole is attracted to the black hole mass. The black hole mass doesn't send out gravitons.

Hell if I know.

Dark can DEFINITELY get waaaay darker than we know about now. I've thought this for years. We just need to invent the opposite of this:

Dark Suckers

Bell Labs Proves Existence of Dark Suckers

For years it has been believed that electric bulbs emitted light. However,
recent information from Bell Labs has proven otherwise. Electric bulbs
don't emit light, they suck dark. Thus they now call these bulbs dark
suckers. The dark sucker theory, according to a Bell Labs spokesperson,
proves the existence of dark, that dark has mass heavier than that of
light, and that dark is faster than light.

The basis of the dark sucker theory is that electric bulbs suck dark. Take
for example, the dark suckers in the room where you are. There is less dark
right next to them than there is elsewhere. The larger the dark sucker, the
greater its capacity to suck dark. Dark suckers in a parking lot have a
much greater capacity than the ones in this room. As with all things, dark
suckers don't last forever. Once they are full of dark, they can no longer
suck. This is proven by the black spot on a full dark sucker. A candle is a
primitive dark sucker. lA new candle has a white wick. You will notice that
after the first use, the wick turns black, representing all the dark which
has been sucked into it. If you hold a pencil next to the wick of an
operating candle, the tip will turn black because it got in the path of the
dark flowing into the candle.

Unfortunately, these primitive dark suckers have a very limited range.
There are also portable dark suckers. The bulbs in these can't handle all
of the dark by themselves, and must be aided by a dark storage unit. When
the dark storage unit is full, it must be either emptied or replaced before
the portable dark sucker can operate again.

Dark has mass. When dark goes into a dark sucker, friction from this mass
generates heat. Thus it is not wise to touch an operating dark sucker.
Candles present a special problem, as the dark must travel in the solid
wick instead of through glass. This generates a great amount of heat. Thus
it can be very dangerous to touch an operating candle. Dark is also heavier
than light. If you swim deeper and deeper, you notice it gets slowly darker
and darker. When you reach a depth of approximately fifty feet, you are in
total darkness. This is because the heavier dark sinks to the bottom of the
lake and the lighter light floats to the top. The immense power of dark can
be utilized to mans advantage. We can collect the dark that has settled to
the bottom of lakes and push it through turbines, which generate
electricity and help push it to the ocean where it may be safely stored.
Prior to turbines, it was much more difficult to get dark from the rivers
and lakes to the ocean. The Indians recognized this problem, and tried to
solve it. When on a river in a canoe travelling in the same direction as
the flow of the dark, they paddled slowly, so as not to stop the flow of
dark, but when they traveled against the flow of dark, they paddled quickly
so as to help push the dark along its way.

Finally, we must prove that dark is faster than light. If you were to stand
in an illuminated room in front of a closed, dark closet, then slowly open
the closet door, you would see the light slowly enter the closet, but since
the dark is so fast, you would not be able to see the dark leave the
closet.

In conclusion, Bell Labs stated that dark suckers make all our lives much
easier. So the next time you look at an electric bulb remember that it is
indeed a dark sucker.

I guess the darkest darkness would be a space through which no energy in any viewable wavelength was traveling. I don't see how that would change the physical characteristics of that space though. The darkness couldn't suddenly gain substance because it is created through the lack of light rather than the addition of some dark "stuff".

That would almost be like asking "how holey can a hole get? Is it possible that a hole could get so holey that it suddenly became matter and you got stuck"?

I think mankind has to admit sometimes that they know virtually NOTHING about the universe. We're like those bush people who have never seen civilization compared to other brains in this universe. Or worse.
Questions like this sound stupid, but are probably normal things outside our puny brains.

By bush people, do you mean Bush people?

I'll save this disaster of a thread with this:

There is something that can move faster then the speed of light that is: shadows.

If you cast a shadow to a wall far away, a small movement close to the light source will constitute a large movement of the shadow on that far away wall. So if you move something close to c, say 0.9c near the light, the shadow far away will move faster than c.

Of course shadows aren't really things. And photons still only move at c. But we can ignore reality like most happy mental patients would.

WTF did I just read... This thread keeps getting better

It actually made me think of how they found out the universe is 70% dark energy, 25% dark matter... In that sense, I guess it would be possible for dark to exist as "something" and not just as an opposite to something else

It could also explain why the universe keeps expanding even though gravity should attract, if a "dark element" that is even powerful beyond gravity kept spreading it apart

Maybe gravitons only travel one way. Mass outside the black hole is attracted to the black hole mass. The black hole mass doesn't send out gravitons.

Hell if I know.

Gravity works on both bodies with the same force.

F_g = G*(m1*m2)/r^2

Yeah, I know my mass affects everything else to some degree...
I was just trying to explain how black holes do not let any information out (except hawking radiation).
I can't explain it, because I don't know.

This is the point of the thread. So based on what you just said, it is possible that dark is not empty ? That something may be present or would have to be present for dark to be dark ?

I would like to sell OP some new light switches with 2 off settings. The second off setting will give you %50 more darkness!

Dark matter is in other dimensions.

OMFG!!! Complex!

dark matter and dark energy don't have anything to do with darkness as our eyes see it. the name is misleading. "dark matter" is called that because it's only been detected by observing the effects of its gravity on galaxies.

Your question makes no sense. We have defined darkness as the absence of light. You're twisting it to assume that once you have the absence of light you can start spontaneously creating matter from nothing. Darkness is not an inherent thing; it is simply the word we've chosen to describe the absence of light. So, no, you can't make it get so dark that things start popping out of thin air. You might as well ask if it can get so blue that squirrels fly on bananas.

This. Without absolute darkness is the complete absence of light. Since there is no such thing as "less than completely absent" there is no "greater darkness." OP you are overthinking it... (or underthinking it maybe).

This thread is insane there is no such thing as "dark" only different levels of light until you reach 0. Dark doesn't exist. same goes for "cold".
