Confusion with "faster than light"
Okay first off hi, this is my first post on these boards, let me clear a few things up here, I'm a bit of a laywoman when it comes to all of this so please go easy on me. I've been into Physics for a couple of years now as a bit of light reading to keep my mind active, I got into it cause of an ex-boyfriend, but the story isn't important.
I've been talking with a couple of people, who seem to be quite scientifically minded, about faster than light travel and/or communication... the problem I'm having is, as I've read and learned that nothing can travel faster than light, now I understand that in relative terms things can appear to, but they do not.
Either way I've been saying this to them all morning and they refuse to acknowledge what I'm saying as correct and that my understanding of relativity is causing my blindness to this.
What I want to know is, in an easy way to understand, and a way I can explain to them:
Can anything travel faster than light other than light (photons and gluons I believe?) and if not, why?
I always believed it was to do with mass etc... but I'm being told that relative speeds of faster than light still count as faster than light, even if in their own frame of reference they are not faster than light, this makes no sense to me, how can it be traveling faster than light when it's only relative? Surely that would make experiments confusing?
To make things worse they are now talking about Quantum Mechanics and how I'm Einsteinian for not knowing the details of Quantum Entanglement, when I've never claimed to be an expert on any of this, just curious.
So if you guys/gals could help me out here with my understanding that would be really appreciated.
Hayley.
