: So it the lenght contraction just an illusion?

: If an object with mass is approaching the speed : of light it's energy is being increased. Therefore : it's mass is being increased too. correct... its relativistic mass increases. not true mass.

: 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)

: So, what in reality has shortened? Or is this : relative like that absolute path doesn't exist? : of course you can't say that something is absolutley : moving on line or parabola...

Nothing in reality has shortened. just fact that the space you are traveling on becomes curved.

: : 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.

: Please help :) I hope I did! :) take care...
