Scientists decode the first confirmed alien transmission from outer space...

"This really works! Just send 5*10^50 atoms of hydrogen to each of the five star systems listed below. Then, add your own system to the top of the list, delete the system at the bottom, and send out copies of this message to 100 other solar systems. If you follow these instructions, within 0.25 of a galactic rotation you are guaranteed to receive enough hydrogen in return to power your civilization until entropy reaches its maximum!"
