But it is because we live on the Earth, trapped to its surface by its gravity. Thus, we have an objective frame of reference, it is the Earth, and the speed ...

Smarter guys will get through the complicated, maths-heavy explanations, but in term of wrapping your mind around the idea: In that local frame of reference over the cosmic event horizon, you're not moving, no more than you're currently moving at higher speed than 3x10^8m/s from a over-the-horizon-distant point in space. Keep in mind there is no such thing ...

First, let's clear up a few misconceptions: The Hubble sphere The speed of light as an upper limit is valid in special relativity (SR). In general relativity (GR), which must be used to describe the expansion of the Universe, although locally (i.e. where SR is a good approximation) you cannot exceed the speed of light, there is no limit to the relative ...
