The bible and elsewhere told us that demons caused illness. Finally people decided that maybe illnesses may have other causes and found them. You tell me that time dilation exists. I know that time is not a dimension so it is a matter of looking for the right explanation. Have you got a 300 metre plus cloud chamber for me too, to prove time dilation? Or are you just parroting what you have been told and what you have read? Circular motion at constant speed is not centripetal acceleration. Where do you get this rubbish?
