What is more powerful … light or absence of light?

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.

Sunset,\nBut sunrise is more peaceful

I think you mean illumination. Inspiration is quite a thing apart and almost never seen.

I'd say sight.\n\nI can't imagine what life would be like if I can't see...\nOf course, the other senses are important too. If we lose even one of them... I don't even wanna think about it.\n\nBut it's inevitable.

No, time and light are not the same thing.  You can have time without light.  You're probably thinking of mass and energy.

This can be proven with a simple experiment.  Light travels at 186,000 mps, if you go to a desk or anything with a drawer that can be pulled out, while the drawer is closed it can be fairly safe to say that it's dark in the drawer.  When you open the drawer you will find that the dark excaped before the light got in.  So, you can safely say that darkness travels faster than the speed of light.

Light is not air, and definitely not the same kind of 'light' that is meant with 'light as a feather'.\n\nThese are the short definitions:\n'The light shines upon you': Light = electromagnetic waves called photons\n'Light as a feather': Has a low weight compared to the size of the object

the most purest form of generating light without heat is utilized by certain creatures that "glow in the dark".  it is called "bioluminescence".  ( e.g. fireflies , luminescent bacteria etc ).  they use certain chemical reactions to produce light.\n\ncyclotron radiation also does this ( but a abstractly difficult concept to understand ).\n\ntheoretically, however, the second law of thermodynamics states that all energy transformations must "waste" a certain portion of the transformation as entropy ( or heat ) .  this is unavoidable and so ANY method of generating light MUST involve a loss in the form of heat.\n\nhope it answered your most delightful question :)

light my son light.\ndarkness means 0% illumination.As light from a star  travels in all direction it covers all of the universe(and never gets destroyed in vaccum so keeps on travelling) And there are so many stars.\nonly a small part of the space is filled with light absorbing object and black holes.So almost 90% of space is occupied by light.\nso light is the king!!!!

if we need light to see, what does light use to see? How does light illuminate itself. The answer is that light is light already, you are the one who needs it to see. You cannot fathom the mystery of God but God is existence itself and it is impossible for such not to actually exist

I would say the Sun. You need it in order to create evaporation to create the clouds that produce rain. Without it, there would be no rain.\n\nAfter reading the additional comments, the sun is still more important than rain. Sure, we can create our own light but it isn't economically feasible to create enough sources of light for plants to photosynthesize and create Oxygen for us to breathe. The Sun's light covers a much wider area than we could imagine or build for, at least economically speaking.\n\nWe can live without water for a short time, but we can't live without oxygen. If the plants stop producing oxygen because of lack of light, we'll die even if we have an abundance of water.

Light is faster because electricity has to interact with the atoms it finds as it moves along a wire. Electricity is only a BIT slower than light, but you cannot tell the difference in real-life situations.

light is energy and, thus, has no mass.

the speed of light of course.  dark is the absence of light, so theoretically, the speed of darkness moving in is the same as the speed of light moving out.

Light is emitted by objects that are very hot.\nLight is emitted by objects that are at very high temperatures.

Light, as we know it, is a rush of photons.  As the photons go along, they would leave a darkness behind the last photon that would follow along at the speed of light.\n\nSince darkness is the absence of light (light would be something like the force acting upon or going through the dark), then by itself, dark has no speed.  It just is.

light has constant speed... a big zero acceleration....\nlight does not have mass so no inertia... but amazingly has momentum...........
