BATTLESHIP Featurette - Goldilocks Planets

The folks at SFX shared a cool Battleship featurette. A Goldilocks planet matchs the size of our sun and our orbit/distance from it. The idea is that those planets are most likely to have life. Earth attempts to contact these planets, so the aliens come to Earth invited.

We are currently sending out our location to these Goldilocks planets. Do you agree with Stephen Hawking that this is a very bad idea?

Synopsis:

In the Hawaiian Islands, an international naval fleet at Pearl Harbor engage in a dynamic and intense battle against an alien species known as "The Regents". The aliens come to planet Earth on a mission to build a power source in the ocean. Upon their visit, they come in contact with the naval fleet. The film is also purported to show both sides of the story, from the aliens' perspective, as well as the humans' so the audience knows exactly where the opponent's ships are.
