what effect would increasing the speed of the spacecraft have on the astronaut's pulse as measured by the astronaut and by the earth observer? why. I think in both measurements, an increased pulse rate will be found?..
v is the relative velocity between the observer and the observed. The astronaut isn't moving relative to herself. In that case v=0.so...the astronaut will observe ...her pulse being slowed down?....:Sstill confused
I'd be curious what that something is. A moving observer never observes her own heart beating slow or her own clocks running slow. She can consider herself 'at rest'. At v=0. That's why it's called the "Specialy theory of relativity". Every observer can consider their own time reference as unchanging.righttt........i think i said i know to somthing else....
