10 common misconceptions in physics

The true power of science is that it perpetually refines our understanding based on new evidence.

A key part of a scientist’s job is to question everything – including the things we think we know.

Through the ages, many ideas considered “facts” have been revealed as common misconceptions. To name a few: the Earth is flat (nope), your tongue has taste “zones” (that map of the tongue you remember from elementary school is wrong), and lightning can’t strike the same place twice (a small area in Venezuela gets roughly 1.2 million strikes each year).

Indeed, one of the most common scientific misconceptions is that science is full of facts. Rather, science is a field in which the best current models of understanding can either be supported or disproved by evidence.

Here, we debunk a few of the more common scientific misconceptions.
