Hello Forum,
I have been studying special relativity and its unique phenomena (time dilation, length contraction, mass dilation, etc.)
I would like to make sure that my understanding of these interesting phenomena is correct. For example, the length of an object is not an absolute. What we ordinarily call the length is the proper length in our proper reference frame. Someone moving relative to us would judge that length to be different. Who's right? we all are. We are just so accustomed to measure length (distance interval) in a certain way and time interval the same way...
What about mass? Well, relativistic mass can increase with increasing speed. But does not mean that the object acquires more atoms and molecules because it really doesn't, correct?
thanks,
