Right now, you’re moving through space at about 370 kilometers per second. And you can’t feel a thing.
That’s the speed of our solar system relative to the cosmic microwave background. Our whole Local Group of galaxies moves at roughly 620 km/s relative to the same background. Different objects, different numbers: they are never added together. You don’t feel it because steady motion produces no sensation; only a change in motion can be felt.

Visuals: our own illustrative model of the local universe (published directions of the real structures; flows are a model, not measured trajectories); motion vectors in their measured directions (Planck 2018).
