I have no problem on understanding negative velocities (excuse me, because I didn't know the term "velocity" in english means the speed vector, as in spanish "velocidad" means speed and also its vector, althought we also call the module of the vector "celeridad"). But getting back to the issue...

Thank you for both advices. I'll answer the second first; I am serious about getting a concept and being able to understand relativity at a "pedestrian" level, but unfortunately I don't have the time nor the mathemathical handling to dedicate, and I consider this a curiosity hobby. However, I...

Okay, I was wrong for the assumption that they simply weren't accurate enough - It was simply a way to justify my own believes. Now, seeing that the experimental part is getting more sense, I am understanding a bit more. Thanks for the link. It's dense but I'll be giving it a look when I have...

I am reading all of you guys, this evening (europe timezone) I'll look your answers with a bit deeper read so I can reply properly. My mind should be on the exam but it's on this (lol)

Thank you so much for your help. Asuming p=m·v, and that we are talking about a non massless object, E=mc2 is valid when v=0, so we get the rest energy. The other equation you gave me perfectly satisfies my question about this strange mass increasing it seemed to be on the original equation. I...

I have been searching a bit, but can't find a response to the absolute light speed issue. Sorry if I simply couldn't find it EDIT; Just find a clue on the first page, by user https://www.physicsforums.com/members/hallsofivy.331/ ; If object B is moving at speed u relative to observer A and...

Hello everybody. I am an spanish student of a bsc in Chemical Engineering, so as you can imagine, all this questions are going to be purely curiosity. First of all, sorry for any english language mistake I can commit. I have always been curious of the spacetime issues, and how the world really...
