ASU KEDtalks: Visitors from Another World

So here’s the thing about mete­orites. They’re not some strange or obscure phe­nom­e­na. They are cen­tral to under­stand­ing the ori­gin of our home plan­et, to our very exis­tence on this plan­et, and even to our future.

The Conversation #21 — Robert Zubrin

So long as we’re lim­it­ed to one plan­et, ulti­mate­ly our resources are lim­it­ed. And there­fore every per­son in the world is com­pet­ing with every oth­er per­son in the world for a piece of a finite pie. Okay, and every new per­son born is a threat, every nation is fun­da­men­tal­ly the ene­my of every oth­er nation, every race of every oth­er race, and the only ques­tion is how do we kill them.

The Conversation #8 — Chris McKay

Everything we know about bio­log­i­cal sci­ences, med­i­cine, agri­cul­ture, dis­ease, what­ev­er, is based on study­ing one exam­ple of life. Life on Earth. Life as we know it. If we find anoth­er exam­ple that’s dif­fer­ent, a sec­ond gen­e­sis, and inde­pen­dent ori­gin of life, com­par­ing those two might enable us to answer ques­tions that we would nev­er be able to answer if we only had one exam­ple to study. That could pro­vide prac­ti­cal ben­e­fits for humans as well as bet­ter under­stand­ing of how to man­age ecosys­tems, etc.
