If dark is dark and light is light what is time when it stands still in the shadow of light?

its time to stop thinking! but i like the poetry

u might have heard abt latitudes. Sun light constantly falls on earth. as earth moves different past of earth receives light and this is what we term as day and night. Latitudes help in determining times and it takes 15mins for sun to pass from one latitide to another. In other words we have time zones ever heard of green whtch time zone. This way, time is calculated with respect to sunrise and sunset. \n\nThus its all depending on how sunlight reaches in ur region..!

I assume you are talking about a photo or something that shows a shadow and you want to know what time of year it was taken? If not then I can't help!\n\nBut if this is what you are asking, then everyday as the sun rises and sets a shadow will appear to move around an onject (as in a sun dial). So when the shadow is pointing in the same direction as that in the photo you have your time. \n\nHowever during the year the sun will rise and set at different heights, and therefore the shadow will appear taller or shorter. Again if you compare this to the shadow in the photo you should be able to get a rough idea when the photo was taken.\n\nHope this helps.

Time is completely relative.  It bends with the curvature of space.  Space is the absence of matter and is what separates matter from matter and matter from anti-matter.  Anti-matter is the opposite of matter and is responsible for anomalies like black holes and is believed to be the center of galaxies.  Anti-matter and matter form energy when they combine.  So far as we can tell, it looks like a giant flash of light when this occurs.\n\nTo answer your question:\nWhen time is removed from the equation, everything comes to a standstill.  It would be the same if you took away energy.  There would be nothing but stuff standing motionless.  When space is removed from the equation, all matter and anti matter are combined and as a result, pure energy is given off as a byproduct.  If matter is removed from the picture, the only thing that would be left is anti matter, space and energy.  Everything would be dark because there wouldn't be anything to give off light, but there would still be gravitational forces at work.

Dark does not push light away, the light is what is moving. Using your example of "over the horizon", the sun (which produces light) moves to the other side of the earth (where we can't see it) then we see dark. But dark does not move, it is just the term we have come up with for what it looks like when there is no light present.

Sorry but darkness is not a measurable thing. the absence of light however is! The absolute absence of light leaves the condition referred to as darkness. likewise cold does not exist only the absence of heat. thermal dissipation is the term I believe so I guess we could call darkness, photonic dissipation? wink wink nudge nudge.

Speed of darkness is unmeasurable itself, It can only be measured as the speed of the exiting of light. So in short, just as fast as night, just when there is no light, there's darkness instead. More of a concept than a tangible thing.

light.\n\nlet me refer you to e=mc2...light has mass energy and inertia.\na light is a wave and a particle.\nIt is in motion, and objects in motion have inertia and thusly power.\n\nThe true absence of light would exist in a vacuum. There is no pwer in a true vacuum. Even if the absence of light was "massive", that word you chose is a relative term, which is to say that massive CAN NOT imply mass, inertia, etc. The absence of light is NOT measurable because there is nothing there to exist.

i dont know the exact speed but its faster than the light. want proof darkness is always been there before the light. " at first there was darkness then ...'let there be light" - genesis

time is not the movement of light. \nit is only perceived that way because it's the fastest thing we know of.  \n\nIf you traveled to a planet that is 4 lightyears away in only 3 years, time has still passed, and you are still older, you have simply managed to get to that planet faster than light waves were able to.

There is no speed of darkness.  Darkness is simply an absence of light.

relative means what you compare it to, so anything can be still. even me, although im moving on the earth at a very high speed. if i compare myself to my computer, i am standing still. \n\nspeed of light relative to whatever isnt moving, otherwise it wouldnt be the speed of light. actually this is getting advanced, i think the speed of light is a tricky subject because it does not obey traditional newtonian physics

In a dark(ened) room.\nUse a smal lamp. Move it up and down. Choose one pupil and let the other ones see how the length of his shadow changes with the altitude of the lamp.

light travels as fast as it always travels, no matter what it shines through. Things block light, but it doesn't slow it down.

i saw many good answers to this question but none of them address your question from a theoretical standpoint.\n\n1. the question of whether "something" ( or any physical entity ) casts a shadow is irrelevant to us being able to "see" the shadow  or the entity ( which is what many of the other questions address ).\n\n2.  therefore, consider a single atom or molecule.  it "exists" in space ( but is invisible ) and when it is subject to light ( a stream of photons ), it WILL alter their paths. ( no question )\n\n3.  a shadow is defined as a variation in the intensity of light cast by an object.  any alteration from the original pattern of photons caused by these atoms CAN be measured ( on a surface or other medium ( film etc ))\n\n4. this ALTERATION is a shadow in essence.  \n\n5. whether or not the object or the shadow is visible to the naked eye is NOT the issue.  ( people with poor vision cant see many things and microscopes ( as well as other instruments ) enable us to see many other things.)  \n\n5.  the FACT is that any material entity ( i.e atom or collection of atoms ) alters light and its trajectory whether we see it or not with our own eyes.\n\nthe answer to your question is that every "something" ( that you call it ) ALWAYS has a shadow because it EXISTS ( irrelevant to it being invisible or not due the technology ( cloak ) you spoke about ).  its just a matter of measuring the "subtle" shadows with the relevant instruments.

A shadow (not always though).

Light is a very odd thing to try and understand.  It behaves as a wave and as a stream of particles...we call this a dual nature.  You just have to accept it, really.  Light is like nothing else for it has no mass and behaves in two different ways.
