if FE believes the big bang, that means they must believe that explosions cause things to go in all directions
so if things go everywhere, there is no such thing as up
so how are we being "pushed up"


??
also, the explosions must have come from a pressure build up or chemical inbalances (ie a natural explosion) so you cannot disprove that there arn't things "below us" and therefor in space, there is no such thing as up.
and seeing as space is pretty much empty space (yes empty space does exists, because u can make vaccum sealed things where all air was taken out) that means there is nothin to push against, therefore the gases and everything else cannot be held down
if the planet is travelling at a constant speed, we too must travel at that speed (no friction in space so it cannot be disproved). so we are travelling same rate as the planet. there are no forces holding us down because to be held down, we'd need to be pushing against something (which is wat FE says we are doing) so technically, we would just float away according to FE principles
