"Is there a possibility that every star we look at is just our own sun?"
For the most part, movie stars get asked many questions. But recently, the tables were turned, and the stars of the new science fiction film "Passengers" were allowed to ask a NASA scientist the most far-out questions about space travel. Actors Jennifer Lawrence and Michael Sheen pondered the possibilities of time travel and the singularity.
"What's going to be the next groundbreaking discovery in space travel and in propulsion in space?" actor Chris Pratt asked.
