Time is created by gravity right? If you are closer to a strong gravitational field and say you figure out a way to send a message to someone in a weak gravitational field. They will recieve that message at a very slow rate. Or if you do the opposite(send the message from a low gravitational field to a higher one) They will recieve that message at a faster rate. So without gravity is there actually time? I hope I dont sound to dumb on this subject

"We know exactly what gravity does, and we can predict its effect on things with great accuracy, yet we can't say with any certainty, what it is."
