If you were traveling away +aj 2hfnpn 7b9smb6l)from Earth atwg,8my r 3eh7/h1qluf speed 0.5c, would you notice a change in your heartbeat? Would your mass, height, or waistline change? What would observers on Earth using te1w3y/fl,qh 7her8gm u lescopes say about you?
参考答案:
You would not notice a change in your own heartbeat,mass, height or waistline. No matter howfast you are moving relative to Earth, you are at rest in your own reference frame. Thus, you would not notice any changes in your own characteristics. To observers on Earth, you are moving away at 0.5c, which gives $\gamma$ = 0.87. To these observers, it would appear that your heartbeat has slowed by a factor of 0.87, that your mass has increased by a factor of 1/0.87 = 1.15, and that your waistline has decreased by a factor of 0.87 (all due to the relativity equations for time dilation, mass increase, and length contraction), but that your height would be unchanged (since there is no
relative motion between you and Earth in that direction).
