Exploring planetarity

An article from Der Spiegel highlights the "Planetary Summit" in Venice with this beginning: "How does it feel to experience a turning point? To be right in the middle of things when the foundations of our world view are being shifted? Perhaps a bit like this November weekend at the Palazzo Diedo in Venice : confusing and educational, megalomaniacal and inspiring – and often as if a bunch of very smart people had drunk far too much coffee.
"13.8 billion years ago," cosmologist Risa Wechsler explains to the audience in the first round of discussions, "our universe began to expand extremely quickly. In this fraction of a
second, all matter was created." Researcher Christine J. Winter, who is sitting with her on the stage, enthusiastically joins in. "We are all made of ten percent hydrogen - that
means ten percent of each of us is 13.8 billion years old!" she exclaims. "I don't know what to think about that!" The audience probably doesn't know it at this point either. But
the weekend has only just begun."
