Same with light friend. You could explain light to someone who was blind by speaking the formula that determines the properties of whatever light you're referring to. They could even read about it themselves in braile. Bet I can find you a blind physicist. Try again.
What? How does teaching them a formula prove to them light exists? That doesn't logically follow. I am sorry, you are going to have to do better than that.
