Physics, Astronomy & Cosmology / Re: Time dilation and Relativity. Really?
« on: 08/02/2017 10:50:37 »You need to look up the relativistic addition of velocities rule, you will find some very good explanations on the web.
I cannot understand how relativity/time dilation works in a very simple instance. Can someone please help me?
I have three particles A, B and C. B is moving 80% of the speed of light faster than A. C is moving 80% of the speed of light faster than B. Therefore C is moving 160% of the speed of light faster than A. Right? But according to relativity nothing moves faster than the speed of light and time dilation is what allows this to happen. How does time dilation work in the example I have just given?
Come back if you have questions about what you discover.
Remember that in viewing motion in one frame from another, we are not viewing the velocity experienced by the other object, but the velocity we measure from our frame.
