This is because in 106, you don't talk about that fact that one has to accelerate (non-inertial reference frame) to get to near the speed of light. In 106 you are instantly traveling that fast because it's 106. The fact that you have to travel through a non-inertial reference frame to go from traveling near the speed of light to rest with the earth is where your time dilation actually takes place. In General Relativity, you make the distinction that the rocket, not the Earth is the thing accelerating, and Special Relativity problems (ie the problems you see in 106) makes that assumption, they just don't tell you that cause most 106 students just want to pass, not put holes in the ideas. When you do things like that is when the professor asks you if you want to major in physics. ;) When one takes higher and higher level physics courses, one realizes that what the learned in the previous class was just a "special case" made with assumptions they didn't tell you about. > 4) As all electromagnetic pulses travel at/near the speed of light (don't > they?), when I google.com/news, I'd be getting yesterdays news wouldn't I? > The "information's" light clock would slow down as it traveled to my > computer, while my light clock stayed the same, thus I'd grow old while the > information was still young. By the time I got it, I'd be like, "Holy > Crap, I requested that info yesterday!" -more of a joke than logic. No, your mixing this up with using the BYU network which by the time it can connect and load google, a day has gone by. -- Jacob Albretsen [EMAIL PROTECTED] ____________________ BYU Unix Users Group http://uug.byu.edu/ ___________________________________________________________________ List Info: http://uug.byu.edu/cgi-bin/mailman/listinfo/uug-list
