The Drake equation, a seemingly advanced formula, is actually a book of "looking for aliens". It tells us that if you want to find aliens, you have to learn arithmetic – yes, elementary school math!
First of all, you need to know how many new stars are added to the galaxy each year ( (r * This is the equivalent of asking the convenience store at your doorstep how many packs of cigarettes can sell in a year. Next, you have to figure out how many stars have planets around them ( ( f p ) which is like guessing the vacancy rate of the parking lot downstairs in your house. Then, to estimate how many habitable planets there are in each planetary system, it's like finding the roundest one among the shells on the beach.
Don't worry, this is just the beginning. You also have to calculate how many of these habitable planets can give birth to life ( ( (f l ) This is simply more difficult than winning the lottery. Next, we need to figure out how many of these beings can evolve into intelligent beings ( ( ( ) ( ) -
Finally, it is necessary to estimate how long these technologically advanced civilizations will last ( (l ) i.e., which country you want to ** whose network will collapse first. Multiply all of these numbers together, and you get the estimate of the alien civilizations in the galaxy ( (n) Of course, since these numbers are approximate, about the same, the end result is basically a guess. However, this does not stop us from having fun, after all, the search for aliens is a lot of fun! List of high-quality authors
