All 'textbooks' information are monopoly controlled and the truth and facts are whatever they say it is the truth and facts. Has nothing to do with the truth or the facts. Mush. For example...I'm sure everyone here notices Google search engine is being censored, so you might have trouble finding information 'that used to be there and no longer is'. And they shorten the search results for certain topics. So you have to use Tor to see more unfiltered results. Is there Life on Mars? Or....water? What does the 'textbooks' say? Ask any 10 year old the question "Is Pluto a planet?" You might be surprised by their answers... it all depends what garbage they are reading. Garbage in... -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
