1. Certain species of Moth have the ability to detect Pheromones of their own species from a distance up to 2 miles. Surely these Moths do not have a GPS to detect the other Moth from this distance. Then how does their scent gets diffused in the atmosphere of 2 miles of range and reaches the other Moth. The interesting thing is Moth can only be capable of producing not even a part of 1 ml, but still such minute quantity of pheromones get diffused somehow and reach the other Moth 2 miles away. Such small quantity of Pheromones cannot be chemically detected in air but the fact is, this phenomenon has been studies and it exists. Surely there is some science working behind this which is unexplained.
2.Sharks have the ability to sense even a single drop of blood in ocean from up to 2-3 miles. There is no question about their super sensitive sensors which detect the blood in the ocean. But the question is, how , a single drop of blood in the mega area of ocean of 3 miles of range can get diffused and reach the shark 2-3 miles away.
Ratio of some amount of blood in ocean of 3 miles of range or minute quantity of pheromones in 2 miles of atmosphere seems to be super diluted in its medium. But its science or this phenomenon cannot be explained but has been studied. Same way, Homeopathy also works on such micro phenomenon and the science might not be able to explain it. But if science is not able to explain anything, cannot mean that thing or that phenomenon does not exists.
