Sagittarius A-Star's latest activity

This statement suggest you still do not grasp the relativity of simultaneity. Consider for space like separated events ##A,B##, I can...

Proper time recorded by some particular observer's clock at some particular event is independent of any choice of reference frame. But...

Have you completed the figure I described above? Please post it...

This is not what I wrote. In this summary you omit the reference frames and so you ignore, that it is frame-dependent, which events...

This "when" has no absolute meaning in SR. Only with reference to frame B the events [clock A = 80s] and [clock B = 100s] happen...

They can. A clock can (and shall) for example show at 2 P.M. another time than it showed at 1 P.M.

That's not happening at the same moment. With reference to Observer B's rest-frame: Clock B first shows 80s (E2) and ##20s## later...

##\Delta t## is the time interval between two events with respect to frame (x, y, z, t). You did not specify the problem completely...

You wrote in posting #10 under 1) that for observer A, events E1 and E2 happen simultaneously. Newtonian physics postulates (wrongly)...

You describe 4 events (E1 ... E4). E1: clock A shows 100s E2: clock B shows 80s E3: clock B shows 100s E4: clock A shows 80s I call...

I think those people can understand relativity, who had good understanding of and good grades in math and physics high school.

Yes, because it is massless.
