Color is energy… in fact it is an electromagnetic phenomenon, which depends on the way that light is reflected on the objects. Every object absorbs a part of the light which hits it and deflects the rest towards our eyes: this reflected light is interpreted by our brain as a particular color. We shouldn’t, therefore, be surprised to find that the word color comes from the Latin root celare (i.e. 'that which covers, conceals'). Color is then already an illusion per se, a ghost that takes life only in our visual system, when light stimulates the photo-receptors - the antennae that pick up luminous signals – that fill in the background of our eyes. The world surrounding us is sadly in reality monochrome. But there is also another trick: to the eye color is measured partly on the basis of the frequency of light that hits it but above all in relation to colors nearby. A color is perceived to be brighter, for example, if it is surrounded by a complementary color (two colors are said to be complementary if the sum of their radiation equals or gives white) or lighter if the background color is darker. There is then a mechanism that enhances the contrast of the outline of an object relatively to its background: it is called lateral inhibition, because each group of photo-receptors tends to inhibit the response of the one next to it. The result is that which appears to be clear appears even to be more so and vice versa. The same mechanism works for colors: when a photo-receptor from one area of the retina becomes stimulated by a color, those next to it become less sensitive to that color. So, for example, the light blue of a small square that you see on a blue background, appears to our eyes clearer than it would do on a yellow background (because yellow contains no blue).
No-one ever expected the atom to be as bizarre as it turned out to be. Since 1905 when a young Albert Einstein demonstrated for the first time that atoms must exist, they have consistently flummoxed scientists by their weird, almost contradictory behaviour. Here's a quick flavour of just how strange an atom is. And remember atoms aren't obscure objects: everything in the world around us is made of atoms; we are made of atoms. First of all, atoms are ridiculously small - they're about one tenth of a millionth of a millimetre across. That means that a human hair, one of the narrowest things visible to the eye is around a million atoms across. Put another way, there are more atoms in a glass of water than glasses of water in all the oceans in the world.
How Much Of The Universe Is Empty Space
And the story gets really strange. An atom isn't just tiny, it's over 99.9% empty space. All the weight of an atom is concentrated in a mind-numbingly tiny object at its centre. It's a trillionth of a centimetre across and is called the nucleus.'Empty' shellThe rest of the atom is entirely empty apart from a few ghostly objects called electrons that skim about at a great distance from the nucleus. To give you a sense of how empty an atom is - if the nucleus was the size of a football, the nearest electron would be half a mile (0.8km) away.That means even the most solid-looking objects we see are predominantly nothingness. Put another way, if you were to remove all the empty space in the atoms that make up a human being, he or she would be a lot smaller than a grain of salt.If you removed all the empty space from the atoms that make up all the humans on the planet, then you could fit all 6 billion of us inside a single apple.
Why am I telling you all this what importance is there to this information?. Sure you may lol, but please be open. MORE TO COME SOON.
The first question is, "How big is the universe?" No one knows, but this Question of the Day assumes that the universe is a cube that is 30 billion light years on each side. That means that the whole universe contains about 2.7E+31 cubic light years. The next question is, "How much matter does the universe contain?" The mass of the universe is a source of debate right now because there is no easy way to put the universe on a scale. This NASA page and this " Extension, Age and Mass of the Universe" article discuss different techniques that scientists use to estimate the mass. The latter article also includes an estimate of about 1.6E+60 kilograms for the mass of the universe. Other estimates give other numbers, but all are in that ballpark. The next question is, "What density do you want to assume the mass will have once you push all of it into one corner?" Now, if you were really to do this -- if you actually did move all of the mass of the universe into one corner -- it would condense instantly into a black hole and potentially ignite another big bang. But let's say that you could keep it from doing that, and you were somehow able to keep all of the mass evenly distributed at the density of the sun. According to "Magnitudes of Physics", the density of the sun is about 1,410 kilograms per cubic meter. (For comparison, the density of water is 1,000 kilograms per cubic meter.) If you are willing to accept these three assumptions, then: 1.1E+57 cubic meters of matter in the universe A cubic light year contains about 1E+48 cubic meters. So all of the matter in the universe would fit into about 1 billion cubic light years, or a cube that's approximately 1,000 light years on each side. That means that only about 0.0000000000000000000042 percent of the universe contains any matter. The universe is a pretty empty place!

Reality, is to some degree or another, subjective in nature.
The first problem with reality is establishing it. Proving this existence is real - that those around us are real, is something that is decided based upon faith and faith alone. Do you have faith that it is real? Or do you decide to have faith that it is an illusion? Either requires a leap of faith.
Of course, that's presuming you have accepted faith in the notion that you exist, and are not merely the construct of another intelligence - a fleeting bout of 'God's' Schizophrenia.
Science is, essentially, an endeavor to discern just how subjective the mechanics of the life experience are. Presuming we accept the life experience as being real to begin with.

Great thread, I loved the videos on the illusions, but I must reply to this part -
Colour is not an illusion, how we perceive it is the illusion. As it was mentioned in the video, it is simply the way light reflects from the object that is how we perceive it. The more energy the surface absorbs the different the colour we see.
In a situation where there are no abnormal variables, a blue box will always appear blue.
It depends on how you define reality.
I find a good definition to be "That which exists objectively and in fact". There is by definition no subjective component. Our interpretation of reality is of course subjective.
I disagree that we accept reality based on faith. The of evidence that there is an actual reality is irrefutable, namely that we exist. Even if reality is not at all as we observe it (so it is all an illusion), there still has to be a reality.
I guess what you are trying to say is actually similar, but you use a different definition for "reality". Your definition seems to be "that what we observe". But I also disagree that saying that what we observe is in fact reality is a leap of faith. Faith is a believe that has no evidence to back it up, and I think the existence of reality has (consistency in interaction for example). Its not 100% conclusive proof, but that does not mean its faith.
You also say that in order to believe in reality you must assume that you exist and are not the figment of a god. I don't see how these are exclusive. In fact, if you are a figment of a god, you must exist. Just possibly not in the reality we think we do. But how can we know that our universe isn't the mind of a god?
I know that most of the points we disagree in has to do with the definition of "reality". I got my definition from a dictionary, and I think your definition was made up by yourself. That doesn't need to be a problem but you do need to provide your definition in such a case.

I exist? How so?
You accept, on faith, that there is another separate, intelligent being forming the words appearing on your screen. But what proof do you have that these are the product of a separate intelligence? You dream of other people, do you not? Your mind is clearly capable of coming up with illusions that behave in ways that do not make sense to your own self - or that seemingly originate from outside its own array of understandable behavior.
None of the world's mechanics - consistent or not - can be logically utilized as proof of the world's legitimacy. What is the defacto state of a real universe? Order, or chaos?
Perhaps it is sentience that assigns order to the chaos. Perhaps it is chaos that prompts sentience within the order.
You cannot utilize what you faithfully accept as reality to logically prove it is real. It's circular reasoning. Though I do understand your argument - it's like saying: "I know that water is real because I can feel it." ... Which is true insofar as you can experience what you have come to expect.
Well, there are religions out there who postulate we were created in God's image.
However, what you have basically stated is the conclusion that Socrates came to: "I think, therefor I am." Basically stating that he could only come to the conclusion that accepting his own existence and experience as real was the only meaningful outcome.
It is also interesting when considering the 'name' of the Judaic God: "The I Am." - the mark of a sentient being that has pondered and solidified its own existence. How more completely can you describe your existence aside from: "I Am?"
You gravely underestimate my arrogance. This post, and my previous post, are an affront to the very concept of the reality so futilely defined by dictionaries.
