: : : I cannot understand, how space-scientist, can measure long distances?

: : SP=senderplanet : : LI=lightinformation : : RP=receiverplanet.

: : SP send LI. : : RP receice this LI.

: : How RP can knows-says, : : How long LI was travell at space? : : What is size of SP?

: : I dont understand, how we can says, that space is some size, and it is start Big-Bang, and it is exploding.

: : Dont give me answer, Red-shift. : : Wave cannot exist without matter.

: : Still wondering?

: : I think, that we dont know much, how big space is, or how it is started. We are going some kind of strange direction, which is not natural-thing. : : --------------------

: fINE i GOT THE IDEA OF SP-LI-RP, HOWEVER, WHEN OR HOW DOES RP BEGIN TO MEASURE LI.

Good question.

We dont know it.

When we measure light, we must known, what kind light is.

We dont know.

We use 'wave-thinking', but light is some kind of strange matter, because it born matter-source.

And therefore i think, that next tenth years we found new space. ------------- But still. ------------- Basic idea of all existing is not existing. Space start still stay unsolve problem. ----------------------------
