This is a mistaken belief; there is nothing "relative" about it. Nor is it slow "compared to the universe."

The limitation on the speed of anything is a constraint imposed by the geometry of the universe, in which the space and time dimensions are not independent of each other, but are constrained to obey ds² = η_μνdx^μdx^ν.

With this restriction in mind, Galileo was entirely [although fortuitously] correct: light moves not only "extraordinarily rapidly," but it moves at the fastest speed that anything material can.

I was referring to how painfully “slow” it is or at least is perceived when taken in context with the size of the universe.

I am fully aware that it is theoretically the fastest any material “can” physically travel. Some would dispute this.

So dreams of greater than light speed travel are just that? Star Wars and Star Trek are just fiction?

It’s all physics. I’ll get it figured out, as long as I don’t meet a Portuguese waitress.
