If Hollywood has taught us anything, it’s that aliens like to make aggressive statements by blowing up objects of patriotic pride and sentiment. Look no further than “Mars Attacks” and “Independence Day.” An unintended effect of this destruction is that the destruction of sentimental monuments only stirs the human need to fight back.

 

Stephen Hawking believes that an aggressive alien invasion is entirely possible and would not end well for us. “If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,” Hawking says.
