Cosmologists Have Attempted To Account For The

We Could Tell Them [alien Civilization] Things That We Have Discovered In The Realm Of Mathematical Physics, But There Is Stuff That I Would Like To Know. There Are Some Famous Problems Like How To Bring Gravitation And Quantum Physics Together, The Long-sought-after Theory Of Quantum Gravity. But It May Be Hard To Understand The Answer That Comes Back.

What We Want Is Another Sample Of Life, Which Is Not On Our Tree Of Life At All. All Life That We've Studied So Far On Earth Belongs To The Same Tree.

We Don't Know The Answer To That.
