Still 'dancing angels' was not the subject. So they may dance whatever 
they like.

But we were talking about SRT and whether or not someone with an 
advanced spaceship could reach c.

I said, this term 'c' requires a frame of reference, in respect to which 
velocity should be measured.

But SRT says this:

"Examples of this sort, together with the unsuccessful attempts to 
discover any motion of the earth relatively to the “light medium,” 
suggest that the phenomena of electrodynamics as well as of mechanics 
possess no properties corresponding to the idea of absolute rest. They 
suggest rather that, as has already been shown to the first order of 
small quantities, the same laws of electrodynamics and optics will be 
valid for all frames of reference for which the equations of mechanics 
hold good."

But if no absolute rest exists, no absolute reference point exists neither.

This would cause difficulties, if you try to define the meaning of c.

I (kind of) solved this issue by introduction of something I call 
'subjectivism':

any observer is the center of the universe by definition and therefore 
at rest (in respect to himself).

What the observer calls 'universe' is actually his own past light cone, 
hence not universal at all. This 'universe' has an intrinsic speed limit 
we call c, since what is moving faster drops out of sight (out of that 
universe).

So: Since the observer in this advanced spaceship is still at rest, he 
cannot reach c.
