You always hear this phrase if you watch something about astrophysics ‘Nothing can move faster than light’. But speed is only relative. How can this be true if speed can only be experienced/measured relative to something else?

This is a brilliant question. It is the question the led to special relativity!
Motion is relative: the velocity of an object depends on the velocity of the thing measuring it.
Speed of light is not relative: everything measures speed of light the same.
That is the paradox. The universe tells us that is the way it is when we measure it! …and we try to explain why. But I believe understanding should start there, not with explanations of space time.
