: : : : And also, the fact is that from the frame of : : : reference (some 'stationary' point, for example : : : Earth), that object looks shorter. But if you : : : observe stationary point(earth) from that : : : object, it appears like the earth had shorthened.

: : no, the opposite. The earth would appear length : : expanded; or stretched. because from a moving : : reference point, while observing a stationary space/time : : block it appears stretched. (read my other 'point' response : : above)

: Thanks! : But now I don't see why tunnel paradox and twin : paradox are really paradoxes. : ------------------------------------------------

could you explain more. not familiar with the type of paradox you are speaking about.

: : : : Another point, when object with mass is approaching : : : speed of light (let's say 0.999999c) it's third dimension : : : in the direction it's moving disappears.

: : only disappears when the speed of light has been : : achieved.

: So photon is a 2D particle?

interesting point, but I'd have to think about that for a moment. :) but remember, light has no mass. it is energy. Its motion is instaneous across the universe, just we percieve it at a given velocity because it is traveling on the fabric of S/T continuum; Hence the term, Time moves at the speed of light and light moves at the speed of time...
