Einstein said time is relative, and time can be dilated by motion. Newton said time is absolute and time can never change, but only motion can. The point is, if we want to say Einstein is right, first we must prove Newton is wrong about time. Has anyone ever proved Newton is wrong about time? My answer is no. All so-called evidence thought to confirm Einsteinís time dilation, in fact only confirm Newtonís law that all motions can be changed due to forces, but time is still absolute.
We both stand at a roomís corner with two clocks showing the same time. I move one clock to the other end of the room, then give it a really hard shake, then bring it back to check its time with your clock, and it shows 7 minutes slower. Based on my walking speed of 5 km/hr, Einsteinís equation predicts my moving clock would show (say) 2 seconds slower than your stationery clock. All physicists say the result is close enough, therefore they conclude time dilation has been experimentally proved: when an object moves steadily, its time slows down according to Einsteinís equation.
Now we repeat the same test again with my same movement inside the room at the same speed of 5 km/hr. But this time, not only I give the clock a harder shake, I even throw it to the ceiling fan, smash it many times on the floor, and bring it back, and it shows now 10 minutes faster (not slower). All physicists say, given of other factors, the result is still close enough, therefore they conclude time dilation has been experimentally proved: when an object moves steadily, its time slows down according to Einsteinís equation.
