Have you been to a planet to know better?
No, but I have seen the changes in the angle of Saturn's rings and the movement of clouds in Jupiter through my telescope. In particular is the great red spot of Jupiter which is the easiest to tell if it is there or not. Where does it go? Obviously it must be spherical and
BIGGER than 6 feet. And if they where six feet how would you be able to see more detail as the magnification for the object increases? If it where 6 feet (or around there) you would not be able to fit enough detail on it. Microscopes deal with small objects like that.
Anyways, Dark Matter is hypothetical and its usage it either FE and RE arguments is not convincing at all.
Have you been to a planet Tom? Other than just saying that, wheres the evidence. Plus I think the original quote for "They're like 6 feet wide!" was sarcastic. But I could be wrong...
