Can a buddha communicate with someone in far away places?

Buddha says that he hears some god having foolish thought. I think it's the story of Bakka Brahma. He "transfer" himself to the god's presence and lectures. And his disciples too. That seems like long distance communication. That seems to be well within the realm of science. Now anyone test this? Get a buddha, or a bodhisatva (buddha had many disciples, each can show up on Bakka Brahma tools). Ask them for one number and let the other guesses. Would it works?
