Larry King will host a discussion with Dr. Kaku surrounding recent comments by astrophysicist Stephen Hawking, who said in a documentary that there is likely alien life, but communicating with them could be harmful to the human race. Dr. Hawking’s belief is that a visit from an alien race might be similar to Christopher Columbus’ arrival in the Americas. The interview will air Friday evening (4/30) at 9 p.m., EST (and replay again at Midnight). Stay Tuned for further details.
