    Undergrad Relativistic Doppler Effect near a Black Hole

    Hey everyone, if I were to view a shining person rotating near a black hole at near the speed of light there would be 2 kinds of redshifts: gravitational redshift and relativistic doppler effect redshift. Right? But, say at some point, the person is traveling towards me, then the doppler effect...

    Undergrad Time Dilation on 3D Torus: Clock Speed & Why It Matters

    Assume that space is a three-dimensional torus ( a 3D donut) . If there is a clock traveling at a CONSTANT speed in a direction parallel to the torus (inside out of the hole) and one clock that is still. Which clock ticks faster and why? I know that the clock rotating will tick slower, but I...

    Undergrad Newton's 3rd law and ether in space

    Hey everyone, I've read in an article that Newton's 3rd law proves that there is no ether in space. It says, according to Newton's 3rd law, the mass of the space between objects should be 0; then, ether does not actually exist. Could you please explain to me why Newton's 3rd law imply that the...
