So now we start moving towards PSR J1748−2446ad at 0.995c, does the 70,000km remain the same or to the speed of light (minus a very small number).
Let's change the entire object under consideration. We have a high tech disk with a radius of 10km (like a typical neutron star).
A dim continuous red light is emitted from one node on the circumference, and a dim continuous blue light is emitted rom the opposite end.
As the two nodes...
I see now.
Thus, since equator of the neutron star (whose axis of rotation is parallel to the direction between the observer and the neutron star) is in a plane perpendicular to the observer, the tangential velocity also always remains perpendicular to the observer; thus, the rate of rotation...
I understand this part. We could receive nothing other than 20x the number of pulses compared to the initial observation when there no significant motion between the frames.
After watching a few lecture videos on the Relativistic Doppler Effect, this is an absolute fact. I am traveling into a...
So you're claiming that the time between pulsar's emission is not equal to time between the neutron star's very own rotation?
Each rotation of the neutron star is one pulse.
Yet the Relativistic Doppler effect is compacting 20 pulses into the same time interval when travelling at 0.995c...
The problem is conceptualizing what that means.
Suppose there is no significant change in velocity between the frame of the observer and the neutron star. We then observe an acceleration in the pulses from 100 times per second to 2000 times per second. This could only happen if the radius of...

A neutron star pulses 100 times per second from earth, we then move towards it at 0.995 times the speed of light. How many times does the neutron star pulse in the moving frame.
Also, neutron star is rotating at 0.6...
I'm going to check it out and see if I get something other than 0.6c
Also, I assume I'm going to need a relativistic formulation of angular momentum as well, I will have to hold the axis parallel to the direction between the observer and the pulsar to trivialize one of the conditions (that is...
Great, since it's so easy, what's the answer? What speed of rotation will be observed for the neutron star?
I keep getting the original answer, which is 0.6c, due to both time and space dilation (that is, the rotation rate remains constant, since my unit of length is also dilated).
Let us suppose our velocity towards a distant neutron star roughly equated to a dilation factor of 10. On board our vessel we are equipped with a NIST-F2 atomic clock . Since the clock travels with us, it also experiences the same dilation; thus, in our frame, the clock keeps time the same as...
Ok, so the first derivative is zero at the center of the object, which makes sense. So the effect on the curvature from the surface of an object to its center decreases, as noted by inflection point located at the boundary between the grey and black shade ( I assume this boundary represents the...
Ok, so given everything that I know, and that light travels in a straight line geodesic, then the path of light from the exterior object towards its center has the following parametric equation in 4D space.
x = a1(t) + 0
y = a2(t) + 0
z = a3(t) + 0 (without gravity we'd stop here)...
I found this to be the most useful answer to the question.I do want to partition the response though.
Suppose we had five rings around a star. Let the radius of the star (center to surface) = A
The first ring occurs r = 2A, the second ring occurs are r = A, the third ring occurs at r = 1/2 A...
