I was recently being taken to the BBC for an interview, which is about the only time I ever get to travel in a taxi. On this particular day, when the taxi driver asked me what I did and I told him I was an astronomer, he started asking me about extra-terrestrial civilisations. I suggested he watched this wonderful movie, Contact, based on the book that Carl Sagan published in the mid 1990s.
Sagan then co-wrote the screenplay for the movie with his wife. The movie stars Jodie Foster and Matthew McConaughey. Sadly, during the filming, Sagan died of cancer.
If you enjoy the film I would highly recommend the book. The book has some interesting additional complexity, which I won’t go into as otherwise I will give away the surprises. But it s a fantastic read from one of the most gifted scientists and science communicators of the 20th Century.
