Neil deGrasse Tyson - Space Aliens don't give a shit about Humans on earth



Let's face it: The Earth is going to get hit by an asteroid someday. But how bad that'll be depends entirely how big it is. So how big would that space rock have to be to wipe us all out? Let's break it down, from the likeliest culprits to the hypothetical super-asteroids, and what we can do to hopefully not die.
 


"We're stuck at type zero. But what would it take to move between universes? What would it take to enter a black hole? What would it take to break the light barrier?"

If alien life exists, how would we even recognize it? Physicist Michio Kaku argues that our search for intelligence beyond Earth forces us to question the assumptions behind our own definition of “intelligent.”

Our current criteria for intelligence might be too narrow. Here’s what that means for the search for extraterrestrial life.
