The Drake Equation

There are three dimensions of space that we have to look through. We don't know how strong a transmitter out there might be and how far away it is. And for spatial dimensions, do we look in the directions of stars like our own? Or do we look at the most numerous and closest stars, which are tiny, little red dwarfs? Her's all these different parometers that we need to search through. So i know very little about this topic, but i have heard about what's called the drake equation. It's a great way to think about all the things that we don't know about.
