Educate yourselves. en.wikipedia.org/wiki/List_of_common_misconceptions My personal favorites: Evolution does not violate the Second Law of Thermodynamics. A common argument against evolution is that entropy, according to the Second Law of Thermodynamics, increases over time, and thus evolution could not produce increased complexity. However, the law does not refer to complexity and only applies to isolated systems, where no transfer of heat or matter between the system and its surroundings is allowed. The Earth is not an isolated system, as it absorbs and radiates the Suns energy. Black holes, contrary to their common image, have the same gravitational effects as any other equal mass in their place. They will draw objects nearby towards them, just as any other planetary body does, except at very close distances. If, for example, the Sun were replaced by a black hole of equal mass, the orbits of the planets would be essentially unaffected. A black hole can act like a cosmic vacuum cleaner and pull a substantial inflow of matter, but only if the star it forms from is already having a similar effect on surrounding matter. Humans have more than the commonly cited five senses. Although definitions vary, the actual number ranges from 9 to more than 20. In addition to sight, smell, taste, touch, and hearing, which were the senses identified by Aristotle, humans can sense balance and acceleration (equilibrioception), pain (nociception), body and limb position (proprioception or kinesthetic sense), and relative temperature (thermoception). Other senses sometimes identified are the sense of time, itching, pressure, hunger, thirst, fullness of the stomach, need to urinate, need to defecate, and blood carbon dioxide levels.
