Humans Are ‘a Species in a Very Rare Planet’: Cosmologist Makes the Case Against Existential Dread

While some might respond to the vastness of the universe with a sense of existential dread, physicist and cosmologist Marcelo Gleiser takes a different approach, offering up something he calls “human centrism.” He defines it as an “awareness of how important we are in this moment in cosmic history.” He explains that “for the first time, we actually have enough knowledge about astronomy, about physics and biology, to understand how precious and how fragile our condition is.” He says this mindset is especially important in an age of climate change and political polarization.
