: If i look at space, then my eyes come something. : I can see some form, 'light', etc. : Some kind of object, planets, send this information.
: Can i measure, what is distance between me and object?
: M=me : O=object : LV=lightview
: : M....LV.....O
: I dont know, nothing, what kind O is.
: I cannot say, : what is distance between me and object.
: LV, that is what we see.
: What do we know this LV information?
: It has form, when we see it. : It has some kind of speed, near earth. : It is some kind of matter-moving process(radiowaves, light, etc.)
: We cannot say reading this LV information, : what is distance between us and object.
: When we see light at space, or measure radiowaves, : we cannot say, at long distances, what is that distance.
: I think that Big-bang is only a theory at laboratory, not a nature-thing. :::::::::::: Interesting. You do pose fundamental questions.
Doppler shift does help tho to measure distance to far away objects and parallax works well for near ones. Distance CAN be known or at least approximated well.
But... If the Big Bang is not a "nature-thing" then what do you think is the cause of the state of the universe as we see it to be from our limited perspective?
