Inverse-Square Law

Light can travel at varying speeds. In some spells the light generated travels instantaneously while in other spells light travels at a slow enough pace to watch its cloud form move.

Some forms of light are magical and some are mundane. Light from the sun or candles instantaneously light up what they hit. This form of light has not been known to move slow enough to watch it move.

Light sometimes follows the Inverse Square Law. The strength of light is inversely proportional to the distance from its source.

Force

Larger size does not automatically imply larger strength. Beings who have a lot of experience are generally stronger than those of the same size who have had less experience. Some beings of large size are weaker than some beings of smaller size.

Some magical beings can move without the need to push on something. Land creatures move by having the world push on their feet and their feet push on the world. Air creatures move by having the air push on their wings and the wings push on the air. Floating beings such as Liches move by magic or soul substance pushing on the air. Titans can move without pushing on anything because the Great Dark is empty.

Gravity

Generally, in the Warcraft Universe larger creatures such as Dragons have less weight than for their size than smaller creatures. This allows them to move as easily as a smaller creature would.

In the Warcraft Universe, creatures with wings such as dragons can fly even though their massive weight would not allow it.

In Outland, there are rock chunks which float above the ground which generate their own unilateral gravitational field. A being who is above them feels the gravity below them, but below the rock chunks there is no gravity pulling beings up. Since these have been only seen in Outland, it is hypothesized that there are different physics at work in different parts of the universe.

Magic can change gravity. The Blood Elves have a city which defies gravitational forces which would send it crashing to the planet's surface presumeably through the Blood Elves' magic.

Matter

Matter can be transformed into other types of matter. Alchemists have the ability to change one type of matter into another type of matter.

Time

In the Warcraft Universe, beings can travel forward or backwards through time and have the abillity to change history sometimes. In the Burning Crusade, beings can travel through time to battle Archimonde but their deeds will not affect later outcomes in history.

The Twisting Nether has been theorized to lack time. The Twisting Nether is a dimension used in the spells [Astral Recall] and Ritual of Summoningwhich seems to instantaneously send its occupant to another place. It could also be possible that the Twisting Nether sends its occupants at a speed so fast that it only seems instantaneous.

The Twisting Nether could also have a separate set of time. Travel in the Twisting Nether could be instantaneous because time in this dimension does not equate to time in the universe, causing time to freeze for all occupants in the universe in relation to occupants in the Twisting Nether and vice versa.

History could be predetermined. Prophets such as Medivh can sense future events. If he saw the exact events, history could be predetermined. If he could only sense an unclear danger, history might not be predetermined.

Dimensions

All known dimensions have three physical dimensions. In no known dimension do its inhabitants flatten out (2D) or become lines (1D).

Some dimensions are planar. The Elemental Planes are not spherical like Azeroth or Outland. They are planar, stretching out to unknown lenghts. It is not known how far these planar dimensions extend up or down. Traveling too far up or down in these planar dimensions could theoretically send the traveler into another Elemental Plane because the dimensions are three tiered.

Although most dimensions have time which corresponds to all other dimensions, some may not. The Twisting Nether could be a dimension without time (see time section).

Souls

Bodies are moved by souls or magical means. Upon death, beings turn into a soul which is a mirror image version of themselves made up of soul substance. These souls can inhabit different bodies and control it. For example, Sargeras co-inhabited Medivh's body with Medivh's soul and both fought for control of his body. These souls probably cause beings to move because without them beings have not been seen to move unless they move by magical means such as golems.

Night Elves have different souls. Night Elves' souls look like a cloud sphere unlike regular souls. Their souls also move faster.
