What is the speed of dark?

? total blindness means no visual processing due to the malfunctioning eyes, brain, nerves or some combination

you dont "see" darkness - there is literally nothing to see - you just have an absence of light to process
darkness is the absence of light
all that you see is light - colored objects are objects that absorb the visual spectrum of light and reflect the color light that you call the object
an orange for example - if it is the color orange - is absorbing all light but the color orange which it reflects and your eyes "see" aka processes the reflected photons of the wavelength(energy) of the type corresponding with orange (and possibly other non-visible electromagnetic radiation)

Visible light is composed of photons in the energy range of around 2 to 3 eV (Fig. 3). As the energy of the light increases, the wavelength decreases. Orange light with a wavelength of 620 nanometers is composed of photons with energy of 2 eV. It is the energy range of 1.8 to 3.1 eV which triggers the photo receptors in the eye. Lower energies (longer wavelengths) are not detected by the human eye but can be detected by special infrared sensors. Higher energies (shorter wavelengths) such as x-rays are detected by x-ray sensitive photographic film or again by special devices.

darkness is nothing
nothing has no speed
you dont see a movement of "darkness" you see the movement of light- you can view it as the progression of the void or whatever but that is just the same as describing the word "potato" as every word that isn't "potato". It can be done but its the long way around getting to what is really going on.

Eternity is not infinite since Eternity does not exist.

Everything is Finite.

Nothing is Eternal in the Universe, INCLUDING the Universe.

Well, they don't "see" anything. None of us do. Even if we have 20/20 vision.

You have to remember, your eyes are nothing more than window panes.

It's your brain that interprets the signals and composes the picture.

So although your eyes are non functioning, it doesn't mean your optic nerves or the part of the brain responsible for interpreting sight pictures isn't.

When your brain is still looking for a signal from the optic nerves and has no stimulus (no signal), it simple replaces it with whatever it wants - and typically the greastest number of receptors you have in your eyes are Rods (vs Cones) which only pick up and Black and White.

So the brain says fuck it --- everything is ALL BLACK or everything is ALL WHITE.

That's why when someone gets hit hard enough or knocked out they say all they saw was a FLASH OF WHITE then everything went black.

It's basically the brain's optic sensors going offline and the brain just interpreting "nothing" as being white and then as conciousness fades it all goes black.

What about blackholes? They move at nearly the speed of light. "Black holes can't be seen, but their existence and mass are inferred by their gravitational effects on material around them and by the energy released from all the activity."

Im guessing that black holes are the manifestation of the absolute opposite of light :dunno:





LMAO not Alonzo Mosley!

Black holes may spin at the speed of light but I've not heard of them traveling in their orbits or whatever trajectory they may have at those speeds.
Black holes are the manifestation of stars imploding and falling in on themselves due to their extreme mass and its gravitational pull.

Interesting, I'm wondering how much gravity figures into the question since light cant even escape the gravitational pull of a black hole.

This is the shit, here...I'm not so much interested in the answer as much as the question. There are a lotta quasi-scientists,here postulating, but this doesn't necessarily have to be the opposite of light..it seems it SHOULD BE..But, this could be one of those things that prove we don't know shit...If this is your idea, hats off to ya.

its all about gravity

What is a black hole?
---------------------
Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand black holes in detail, but let's start of slow, by thinking about gravity under fairly simple circumstances.

Suppose that you are standing on the surface of a planet. You throw a rock straight up into the air. Assuming you don't throw it too hard, it will rise for a while, but eventually the acceleration due to the planet's gravity will make it start to fall down again. If you threw the rock hard enough, though, you could make it escape the planet's gravity entirely. It would keep on rising forever. The speed with which you need to throw the rock in order that it just barely escapes the planet's gravity is called the "escape velocity." As you would expect, the escape velocity depends on the mass of the planet: if the planet is extremely massive, then its gravity is very strong, and the escape velocity is high. A lighter planet would have a smaller escape velocity. The escape velocity also depends on how far you are from the planet's center: the closer you are, the higher the escape velocity. The Earth's escape velocity is 11.2 kilometers per second (about 25,000 m.p.h.), while the Moon's is only 2.4 kilometers per second (about 5300 m.p.h.).

Now imagine an object with such an enormous concentration of mass in such a small radius that its escape velocity was greater than the velocity of light. Then, since nothing can go faster than light, nothing can escape the object's gravitational field. Even a beam of light would be pulled back by gravity and would be unable to escape.

The idea of a mass concentration so dense that even light would be trapped goes all the way back to Laplace in the 18th century. Almost immediately after Einstein developed general relativity, Karl Schwarzschild discovered a mathematical solution to the equations of the theory that described such an object. It was only much later, with the work of such people as Oppenheimer, Volkoff, and Snyder in the 1930's, that people thought seriously about the possibility that such objects might actually exist in the Universe. (Yes, this is the same Oppenheimer who ran the Manhattan Project.) These researchers showed that when a sufficiently massive star runs out of fuel, it is unable to support itself against its own gravitational pull, and it should collapse into a black hole.

In general relativity, gravity is a manifestation of the curvature of spacetime. Massive objects distort space and time, so that the usual rules of geometry don't apply anymore. Near a black hole, this distortion of space is extremely severe and causes black holes to have some very strange properties. In particular, a black hole has something called an 'event horizon.' This is a spherical surface that marks the boundary of the black hole. You can pass in through the horizon, but you can't get back out. In fact, once you've crossed the horizon, you're doomed to move inexorably closer and closer to the 'singularity' at the center of the black hole.

You can think of the horizon as the place where the escape velocity equals the velocity of light. Outside of the horizon, the escape velocity is less than the speed of light, so if you fire your rockets hard enough, you can give yourself enough energy to get away. But if you find yourself inside the horizon, then no matter how powerful your rockets are, you can't escape.

The horizon has some very strange geometrical properties. To an observer who is sitting still somewhere far away from the black hole, the horizon seems to be a nice, static, unmoving spherical surface. But once you get close to the horizon, you realize that it has a very large velocity. In fact, it is moving outward at the speed of light! That explains why it is easy to cross the horizon in the inward direction, but impossible to get back out. Since the horizon is moving out at the speed of light, in order to escape back across it, you would have to travel faster than light. You can't go faster than light, and so you can't escape from the black hole.

(If all of this sounds very strange, don't worry. It is strange. The horizon is in a certain sense sitting still, but in another sense it is flying out at the speed of light. It's a bit like Alice in "Through the Looking-Glass": she has to run as fast as she can just to stay in one place.)

Once you're inside of the horizon, spacetime is distorted so much that the coordinates describing radial distance and time switch roles. That is, "r", the coordinate that describes how far away you are from the center, is a timelike coordinate, and "t" is a spacelike one. One consequence of this is that you can't stop yourself from moving to smaller and smaller values of r, just as under ordinary circumstances you can't avoid moving towards the future (that is, towards larger and larger values of t). Eventually, you're bound to hit the singularity at r = 0. You might try to avoid it by firing your rockets, but it's futile: no matter which direction you run, you can't avoid your future. Trying to avoid the center of a black hole once you've crossed the horizon is just like trying to avoid next Thursday.

Incidentally, the name 'black hole' was invented by John Archibald Wheeler, and seems to have stuck because it was much catchier than previous names. Before Wheeler came along, these objects were often referred to as 'frozen stars.' I'll explain why below.

How big is a black hole?
------------------------
There are at least two different ways to describe how big something is. We can say how much mass it has, or we can say how much space it takes up. Let's talk first about the masses of black holes.

There is no limit in principle to how much or how little mass a black hole can have. Any amount of mass at all can in principle be made to form a black hole if you compress it to a high enough density. We suspect that most of the black holes that are actually out there were produced in the deaths of massive stars, and so we expect those black holes to weigh about as much as a massive star. A typical mass for such a stellar black hole would be about 10 times the mass of the Sun, or about 10^{31} kilograms. (Here I'm using scientific notation: 10^{31} means a 1 with 31 zeroes after it, or 10,000,000,000,000,000,000,000,000,000,000.) Astronomers also suspect that many galaxies harbor extremely massive black holes at their centers. These are thought to weigh about a million times as much as the Sun, or 10^{36} kilograms.

The more massive a black hole is, the more space it takes up. In fact, the Schwarzschild radius (which means the radius of the horizon) and the mass are directly proportional to one another: if one black hole weighs ten times as much as another, its radius is ten times as large. A black hole with a mass equal to that of the Sun would have a radius of 3 kilometers. So a typical 10-solar-mass black hole would have a radius of 30 kilometers, and a million-solar-mass black hole at the center of a galaxy would have a radius of 3 million kilometers. Three million kilometers may sound like a lot, but it's actually not so big by astronomical standards. The Sun, for example, has a radius of about 700,000 kilometers, and so that supermassive black hole has a radius only about four times bigger than the Sun.

I have a feeling that we (humans) want to classify things as infinite because we cannot grasp the concept of how vast certain things are (numbers, universe, etc).

I agree with Wing.
Everything is finite, it's just that our minds cannot wrap our heads around the idea over where certain things end.

Darkness is the abscence of light, therefore the speed of darkness is the speed it arrives, therefore the same as the speed of the departure of light. The speed of darkness = the speed of light
 
Do any of us think we were born into the right "time"? In other words do you think your in the right time of history or was placed in the wrong time? How do you know either way?

The Speed of Dark is the direct inverse of the Speed of Light.

Basic Law of Physics = Every Action Has An Equal and Opposite Reaction.

Light molecules (photons) need to displace space in the void ... light photons travel at a certain speed (100,000 miles a second or some crazy shit like that) and once those photons are gone, Darkness re-envelopes the void at the same speed.

It Darkness re-enveloped just a fraction too early, we'd never see the light. A fraction too late, and we'd see a "light pipe" like a shutter on a Camera as it closes its iris.

What's even crazier when you think about it ...
(1) The light we see from the stars tonight, that was cast in some cases 1,000 years ago. It's JUST reaching the Earth now.

(2) Traveling at LIGHT SPEED, and excluding the Sun, it would take us ~4 years to reach the nearest star Proxima Centauri. :eek::eek::eek::eek:

4 years at LIGHT SPEED THE ENTIRE TIME.

Makes you think how small and insignifcant we are.

If you traveled at the speed of light, you would arrive at Proxima Centauri instantly but, the folks on earth watching ur travel will have measured 4yrs passed.

Twin paradox
From Wikipedia

In physics, the twin paradox is a thought experiment in Special Relativity, in which a person who makes a journey into space in a high-speed rocket will return home to find he or she has aged less than an identical twin who stayed on Earth. This result appears puzzling, since the situation seems symmetrical, as the latter twin can be considered to have done the travelling with respect to the former. Hence it is called a "paradox". In fact, there is no contradiction and the apparent paradox is explained within the framework of relativity theory, that only one twin has undergone acceleration and deceleration, thus differentiating the two cases. The effect has been verified experimentally using precise measurements of clocks flown in airplanes.

I disagree, with the twin paradox theory in this case. That only applies to time travel - that is being able to bend time. If I could be in something that could BEND time, then yes - there'd be an instanteous arrival and age difference with my twin because while they had to follow the normal linear time line, I was able to "skip" forward on the path without chronologically aging.

Time is the only known constant in the known universe. So being in a "vehicle" that happens to accelerate or decelerate has no affect on time per se, just the amount of time needed to reach a destination.

If I took a very powerful flashlight and flashed it at Proxima today, someone standing on Proxima wouldn't be seen until 2012 at earliest.

Again, the same constant holds true to the stars we see.

The light we see, was cast by the star in some cases 1,000's years ago. For all we know that motherfucker could have blown itself all to hell in a Nova and we be none the wiser for Centuries until we noticed an erratic wobble or radiaton increases which haven't even reached us yet.
