We are so used to some things that we stopped wondering about them. Like light. What is light? Some kind of wavy thing, right? Kind of.

    Why do different objects reflect light of different wavelength even though the light falling on them is of the same wavelength? For example, why does wood seem brown under white light while a tree leaf seems green under the same white light?

      This is similar question to why a long bass string vibrates with a low frequency while a short viola string vibrates with a high frequency: every system has a different response to different frequencies, and so to the absorption, reflection and scattering spectrum of different materials. The difference between these systems is how their electric charges vibrate when you try drive them. Hope this helped.

    Light: Movement, imparting movement, caused by movement. ^this is the abstract truth, that does not deny any intricate definitions thus following. Teach this as the foundation, and the mystery will have a concept for even children to grasp.

      @ofek10 hello. I've talked this over with physics people before. You can refute this with your own abstract points, but in essence none of this is false.

    • Mine Duck

      @ofek10 but all straight force comes out of the curve, and goes back to the curve. The reason nothing touches is because matter isn't a thing, its movement itself. Its force/charge. It can only make itself spin away in its expansion/inspansion. Very simple but very true.

    • Mine Duck

      @ofek10 what I'm describing is the abstract movement of everything. It is spin, and sphering that 'makes' matter by separating it into its units. There are endless laws and consequence called physics and chemistry, but underwriting them all is the function that makes what we measure. Heat, light, electricity, are the same, gravity is the opposite of movement, of charge. Gravity is the conglomeration, it is the cold death..but in a reality where nothing touches, it becomes a capacitor of movement, like a battery or coil. So when an object has mass, like a planet, the more mass, the more potential energy, amd the more energy needed to get its curve straight again. Technically if the energy was introduced the earth could quickly become a fading dart of plasma. Straight is the electro/magnetic force. Gravity is that force as well, since its the same movement, but it is that forces negative.

      @ofek10 try if you like, but if you can replace or refute what I wrote, I will hear it. To me its not, NOT this. Numbers are symbols and the one and zero do represent, on the number scale and as what they symbolize, the very beginning of reality. 2. There are only two shapes/directions/ways things may be, even in your imagination. Everything in existence is either straight or curved. Given that, I will divide forces into two. This is abstract mind you: straight (electric force/charge) and curve (gravity). So this division can take only two forms. In its omni-expansion, that being within polar volume, the straight force would naturally coalesce with itself, causing stagnation. However as you know, we live in a reality where nothing touches. Ever. So to avoid conglomeration, the straight curved away. As its doing this from amd at all directions, this 3d curving leads to sphering of motion. These spheres create separation, they form the units of matter as we know it. Each individual sphere at whatever scale of the movement. Continued...

      @ofek10 this isn't about the grasps. Indeed physics is not light-minded knowledge, however it does not do much towards describing the causes of what it measures and defines I.e. origins. I wasn't taught what i am describing. In a personal effort to reconcile the discrepancies between plasma cosmology and relativity, I made a hypothesis of what the abstract foundations of reality are. I call it perspective theory. There is an/the expansion, for lack of a better word. In actuality, the expansion is a division. The origins of existence are symbolized in 1 and 0. something/nothing. Existence is 0 ÷ 1. The movement is a division, and the division is matter. How is it that simple? When the Greeks defined zero, they also defined the 'big bang's scenario. As defined, zero (nothing) has no value until it effects a value, yet is the basis of all values. We live in a polarized, cause and effect existence/reality/dimension. The opposite of nothing is something, and vice versa. This creates an issue, how could there be a nothing without a something to define it? This issue is the issue of inexplicable existence, it's an always-paradox. So to start, something and nothing had to both exist simultaneously, so 'something' separates from nothing. They are split, it is a division. 0 ÷ 1 = 0 (then it can't exist without something----->) so ÷ 1 again. This is the expansion, the division creates more 'nothing'. And naturally, volume is polarized. There is just as much expansion within all matter, as out. The only change is perspective. This concludes the first abstract lesson.

    Light actually has mass according to Einstein, because mass and energy are the same thing except that they are just written and expressed differently (E=mc^2). And since light carries energy it therefore must have a mass which is not =0.

    Hang on. Low frequentie moves as fast as high frequentie? At start maybe. But doesn't low frequentie waves decay much faster? While it's completely the other way around with stars. Blue is more violent, red lasts a thousand times longer. Aye because it uses less fuel to burn. Complicated. Why is there a contstant and why is it the same with sound. Very strange. But also very elegant, the way things work. It all seems so simple. Untill the as good as unpredictable electron comes along.

      Oh wait. I get it. Loud noises and whispers travel at the same speed, and maybe as far. Same with light. High frequenties are just much easier to detect over time/travel/distance. It just isn't very important to me. Mass and the energy of two masses attracted to eachother is the only thing that mathers in the universe. Light nor sound can escape mass, so they don't mather.

    One needs to sit and ponder how a living organism less intelligent than us can "choose" to evolve features for its survival, such as eyes that see in the visible spectrum. It is mind boggling to think that one will accept chance as being a cause of all the existence, than to accept that there can be no creation without a creator. A needle will not come about by random events with infinite time at its disposal, eventhough the universe is finite and had finite time in existence. You need someone to create the needle, with all its simplistic shape, let alone a more complex feature such as an eye to evolve. It is more close to logic and science to accept that a creation must have a Creator rather than to accept that they created themselves.

    From what i have seen from Vsauce The reason why light is moving that fast is that the faster you move the slower the time moves in your perspective. And for light. The time doesnt move at all. But on earth we can barely experience this since the fastest speed we reached on earth was only 2000 m per second. While light reaches hundreds of millions of meters per second
