The cost of “herd immunity” for COVID-19 is too high

My latest comic with Maki Naro is up at The Nib, the award-winning nonfiction comics site! This time we tackle the question of “herd immunity” for the COVID-19 pandemic, which has been suggested by a number of politicians as a strategy for beating the disease.

Neutron stars are arguably the strangest objects in the cosmos. Born from the deaths of massive stars, they combine strong gravity with temperatures and densities higher than anything we can make in the lab.

While we’ve known about neutron stars for the better part of a century, astrophysicists still aren’t entirely sure how large they are. That uncertainty is related to two other unanswered questions: What’s in the middle of neutron stars, and how massive can they grow?
