xniburux, when you said that 'planet X' traverses that part of the galaxy, 'that part' referring to the constellation Orion...WOW! You do know,
don't you, that the Galaxy is three-dimensional? When we see a constellation, from our little vantage point in our suburb of a spiral arm, we see
stars that are at various distances, but seem to form a 'pattern' because we humans evolved to see patterns, even when they don't exist.
We see clouds that look like bunnies...or horses....or a Rorscharch inkblot!!! Somebody sold a cornflake on E-Bay because it resembled the state of
Illinois! THAT is madness.....
Back to my point...the stars we observe every night are in constant motion, you know that, right? As is the Sol System, it is moving about something
like 10,000 mph. BUT, due to the incredible distance, these relative motions cannot be detected within one person's lifespan, nor even during the
very small slice of time that we call recorded human history.
This apparent lack of motion, even though everything is moving very rapidly, is due to the tremendous distances involved....it's called
'parallax'.
Say you're on a long, straight road, with mountains in the far distance. The nearby trees whiz by as you travel, but the mountains remain the same
for hours....because from your point of view, they are so far away that your motion relative to them is minimal. That is an analogy for you to
ponder.....
