It's not important to touch a thing to know it. We are not even touching things, we just feel the electric repulsion from atoms. In the same way we can calculate distances, we can project and reflect a laser, we can watch the light spectrum from the moon and know composition of the material. We can know the mass based on orbit and reactions. But today people do not study physics, math or science. The do not study what is the scientific method and do not know or accept that others can know and understand more. 

 Shut up Fed. Back to shitcoining for you. 

 I don't care about coins. I produce things. Coins are a carriers but If you are able to product nothing you have nothing to exchange
