Here is an interesting hour long movie with a realistic quote:

2. Hawking's position is a bit puzzling.

First, every physics we know says that interstellar travel is not only difficult in the extreme, but totally impractical. It's the whole rocket equation business. This is basic physics that Hawking should be able to solve in his head. What it says is that the energy required for interstellar travel imposes a rather severe penalty on those who would attempt it. Such are the distances between stars, let alone the distances between intelligent life forms.

Then, there's the time for communications. Of course, Hawking knows this, too. I just do not understand his position on communicating with putative aliens when a one way communication would likely take centuries, or even millennia, depending on their distance from us.

It's a puzzlement to me. I say broadcast away. The chances it will be received is next to nil anyway. The chances that it will be received within our lifetime is slim. Such are the distances in our galaxy.



BTW, interesting Outer Limits episode. I liked it.
