Are there alien civilizations out there in our Galaxy? This is one of humanity's biggest questions. It is also one of the hardest as we know of only one example so far. Us. However,  a new study published in a journal recently has claimed that our Galaxy possibly holds 36 communicating alien civilizations!! They have used a modified form of the famous Drake Equation to come up with this estimate. But what kind of assumptions did they make in their calculations? Are those assumptions reasonable? Please join astrophysicist Salman Hameed in exploring the Drake Equation and in analyzing the results of this paper.
