Something massive, with roughly 1,000 times the area of Earth, is blocking
the light coming from a distant star known as KIC 8462852, and nobody is
quite sure what it is. As astronomer Tabetha Boyajian investigated this
perplexing celestial object, a colleague suggested something unusual: Could
it be an alien-built megastructure? Such an extraordinary idea would
require extraordinary evidence. In this talk, Boyajian gives us a look at
how scientists search for and test hypotheses when faced with the unknown.
