Stephen Hawking: It’s Time to get the Hell Off Planet Earth

Vox - Theoretical physicist Stephen Hawking has set a deadline for humanity to save itself. Within the next 100 years, he warns, we need to colonize Mars and other planets. If we don’t, we may not survive climate change, disease, and other versions of doom we’re bound to inflict on ourselves this century.

As Katherine Hayhoe, a renowned climate scientist at Texas Tech University and another Starmus speaker, tweeted during Hawking's talk on Tuesday:

@StarmusFestival And that's why cutting our carbon emissions is so essential to all of us: our planet, its people, and even the future of space exploration.
