Dark matter’s existence perplexes people who find it implausible that the vast majority of matter in the universe would be undetectable by our senses and their technological extensions. Some even wonder if it’s a sort of mistake. To me it would be even more astonishing if the matter we can see with our eyes were all the matter there is. You might have thought such hubristic beliefs were upended by the Copernican Revolution. After all, the history of physics is the history of revealing how much is deceptive, or is hidden from view.

Most people mistake their own perspective, shaped by their subjective and limited perception, for the absolute reality of the external world. Questioning this assumption is what advanced our research on dark matter. It is also the only thing that has ever advanced human empathy.

Seeing dark matter as the key to the universe — and human empathy – Lisa Randall. I wonder if Randall (professor of physics at Harvard) thinks that this insight should have any influence on how atheists treat theists.
