Hi guys,
I've recently started studying relativity and I thought I was on a good path but I got a little confused with some concepts. I've red a lot about the Andromeda paradox, the train and tunnel experiment and so on so I'll present my question in a way related to those topics.
In my first 'understanding' of the criteria why simultaneity varies I've thought that if an object is moving towards one event and away from the second that he will have the first one before the second in its plane of simultaneity. This seems true, but I've also found out that if he is moving towards the both with the same velocity as the previously mentioned example he will also have the first before second (along the same axis, parallel that is to say). So combining this with the Andromeda paradox made it fuzzy, because it was clearly stated that while moving towards something you will have its future (relative to the stationary observer) in you present, and moving away causes you to have the past in your frame.
But clearly, the observer that moves towards both of them sees one before or another, so I'm interested in the correlation between that situation and the view of the stationary observer. How will the events relate to both of those frames? And what is the criteria to know when an event you have as present while moving is in the future or the past viewed by a stationary observer?
I hope somebody will clear these misconceptions. Thanks in advance.
