So called facts that are false...
Black Holes - Not really 'holes', but rather hugely dense objects with massive gravitational pull.
Only 5 senses - Some scientists insist on 21, including balance, pain and temperature.
Only 10% of the brain is used - The proportion of the brain "firing" at any one time is task dependent, but ultimately, every region is used almost every day.
Different tongue parts - There are not different sections of the tongue for each taste: bitter, sour, salty, sweet and umami (savory/meaty).
Missing Person's Report - Police don't require a 24-hr waiting period before accepting a missing-person report.
