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


The Event Horizon Telescope Initiative at Perimeter Institute, led by Faculty member Avery Broderick, will analyze and interpret the torrent of data collected by the network’s telescopes, generating humanity’s first image of a black hole and testing fundamental concepts in our understanding of spacetime.

About Perimeter

Perimeter Institute is the world’s largest research hub devoted to theoretical physics. The independent Institute was founded in 1999 to foster breakthroughs in the fundamental understanding of our universe, from the smallest particles to the entire cosmos. Research at Perimeter is motivated by the understanding that fundamental science advances human knowledge and catalyzes innovation, and that today’s theoretical physics is tomorrow’s technology. Located in the Region of Waterloo, the not-for-profit Institute is a unique public-private endeavour, including the Governments of Ontario and Canada, that enables cutting-edge research, trains the next generation of scientific pioneers, and shares the power of physics through award-winning educational outreach and public engagement.
