Hello everyone, great to meet you all.(adsbygoogle = window.adsbygoogle || []).push({});

My name is Alejandro Di Mare, a computer science bachelor from Costa Rica currently studying music in Pasadena, California. For the past few months physics have captured my attention so greatly I'm thinking about persuing a masters degree in the subject next year (I hope I'll eventually be able to help people in this forum instead of asking simple SR questions :P).

I've been reading a few posts on relativity trying to find if this has been addressed, but was unable to find it (I'm pretty sure someone must have asked this to you guys/girls, so I apologize if I force you to repeat yourselves).

I am observing 2 spaceships, A and B. Relative to me, A moves to my left at a speed of 0.75c, B moves to my right at a speed of 0.75c. I'm wondering if one of you guys/girls could explain me how a passenger in spaceship A perceives spaceship B and what results he would obtain in an attempt to meassure it's speed (in a reference frame where A is stationary.).
