a lantern? I'm sorry if this is wrong.
In physical terms - to the ends of the Universe. In practical terms - to the edge, where something more massive has a greater influence. In "our" terms, about 2 light years from the Sun (But all depends in which direction you are looking (thinking).
Electromagnetic waves, mainly visible light.
God made physical light energy to exist before there were any actual 'light givers' such as the sun, moon, (reflected of course) stars, etc. This is seen by some to emphasize the fact that light energy is more fundamental than the existence of any 'light giver'. It would thus make no difference to God whether He created waves of light energy or actual physical bodies that emitted light. This of course He did later as noted in the question. Some have also pointed out that God Himself is referred to as 'light' and the book of Revelation notes that God Himself is to be the source of light at the end of time when the world and universe as we currently know them cease to exist. This seen in one sense as re-creation, or return to an original condition of perfection, so it may give us a clue as to what happened originally.
E=mc2 means that energy in equal to the speed of light times itself.
In terms of inventions, the telescope would have made it possible to do this.
when objects get lighted from other source of light it is known as illumination
The terms light source and illuminant have precise and different meanings. A light source is a physical emitter of radiation such as a candle, a tungsten bulb, and natural daylight. An illuminant is the specification for a potential light source. All light sources can be specified as an illuminant, but not all illuminants can be physically realized as a light source.
In terms of physics, No (because light "interferes" with light from another "source" , creating interference patterns). However "lighting bugs" DO use light to attract a mate!
In Australia, the word Christmas is simply known as Christmas. There are no other terms for this celebration of Christ's birth.

A source in geographic terms means where the river begins in mountains or lakes.
It is the Doppler effect and is caused by the light source or the observer moving towards or away from each other. In basic terms, if the two are moving toward each other then the light waves arrive at the observer more closely packed than when they left the source. That is, the wavelength is shorter and the light becomes shifted towards the blue end of the spectrum. If the two source and observer are moving apart then you get a red shift.This is analogous to the pitch of a siren which drops as the vehicle passes you and starts receding from you.
A highly debatable question. Usually red and green are associated with Christmas. Particularly in terms of decorations.

Sound and water waves differ in one main way in terms of source, although they are very alike. Sound waves are generated by a verifiable sound source, such as vibration.
