    Undergrad When do stationary observers receive signals from a relativistic spaceship?

    I surely would care if I had any idea how. Again, we are not talking in terms of today's technology it's just mental experiments.

    Undergrad When do stationary observers receive signals from a relativistic spaceship?

    yes I see that but we are just doing some mental experiments and we happen to have all the tools and technology to achieve that :) also keep in mind that if you accelerate every atom of your body at the same rate no acceleration can crush your bones, it is the difference of acceleration...

    Undergrad When do stationary observers receive signals from a relativistic spaceship?

    what if the ship is moving in circles around the receiver and keeping the radius with the receiver always constant, can we forget about doppler effect? would the constant velocity change of the ship affect the calculations?

    Undergrad When do stationary observers receive signals from a relativistic spaceship?

    A spaceship traveling at speed of light close to speed of light (wrt inertial reference frame) sending some data every second on their clock to people who are stationary (wrt inertial reference frame). At what time these people would receive this data on their own clock? Let's say for a second...
