Aurora stared, once more at her parchment, it looked like it should make perfect sense but she just couldn't get her head around it. She let out a small groan and rested her head on the desk in front of her. All this was so confusing it was giving her a headache. She looked up at the professor, questions? She couldn't think of anything to ask that would make it easy to understand, she'd just take all the notes she could and look at them over and over until she understood.

SPOILER!!: Aurora's Notes
Drake equation

Calculating the number of extraterrestrial civilisations we can communicate with.

Rate of star formation
Number of stars with planets
Number of hospitable planets
Number of hospitable planets that develop any kind of life
Number of planets with life where the life becomes advanced enough to send out signals
Length of time the advanced life spends on sending signals

N = R* x fp x ne x fl x fi x fc x L
N = the end result (number of planets with intelligent life we can communicate with)
R* = rate of star formation
fp = stars that have planets
ne = hospitable planets per star
fl = planets that develop life
fi = planets with intelligent life
fc = fraction of intelligent life that sends signals
L = length of time the alien civilization sends a signal for
