Suppose there are l0,000 civilizations broadcasting radio signals in the Milky Way GaIaxy right now. On average, how many stars would we have to search before we would expect to hear a signal? Assume there are 500 billion stars in the galaxy. How would the answer change if there were only 100 civilizations instead of 10,000?

- How do we define the time interval of one "second" now, and keep track of elapsed time accurately enough to navigate spacecraft through the solar system, or place you on Earth with a GPS receiver? What place in space is our absolute reference point from which we measure distances in physics? If I climb a ladder more than a few feet I am clearly in danger if I fall. Being foolish, I think I can react fast enough to not hit the ground hard if I have more than 1 second to react. How high would that be when a fall to the ground takes 1 second? Hint: The distance of fall is (1/2) a t2, where a is the acceleration of a falling body and near Earth it is about 10 m/s2 for anything.arrow_forwardOur solar system orbits the center of the Milky Way galaxy in about 200 million years.
