If you had twin 1 on the earth, and twin 2 fly to a star and back at a speed of v with the Earth and star separated by a distance L, twin 1 sends out flashes at intervals of t seconds (measured in his frame). Taking into consideration the numbers of redshifted and blueshifted flashes that the second twin receives, the time for T1 (twin 1) is equal to gamma*T2. How does one explain this using doppler effect?
