Constant revisions by NASA means . . . they don’t have the first clue what will happen until it happens.
LOL, we have a winner! You are SO right tho. Science can tell us some very very few things w/ microscopic certainty. Sadly, science has become like any other pagan religion and is more about prognosticating/divining/PCBabble/etc than actual investigative science or trying to understand our ‘universe’. Too bad b/c there’s lots to learn. Anyway, its refreshing to know someone else sees thru the Wizard of Oz facade.
When NASA does that, it really means they want more money.
