- Purpose of use
- Von Neumann probe estimate. 400 billion stars in the galaxy, how many iterations before a reproducing probe produces a number equivalent to one probe per star. Assume original probe produces 1 per month until T is reached. Every probe after that does the same once its arrived. Average travel time between stars assume 50 years.
