The sun circles the Milky Way at a speed of about 486,000 miles per hour. And every object in the universe is moving apart from the other objects as the universe expands at a constantly accelerating rate.

Velocity
In the general sense, the absolute velocity of any object through space is not a meaningful question according to Einstein's Special Theory of Relativity, which declares that there is no "preferred" inertial frame of reference in space with which to compare the galaxy's motion. (Motion must always be specified with respect to another object.)
With this in mind, many astronomers believe the galaxy is moving through space at approximately 600km per second relative to the observed locations of other nearby galaxies. Most recent estimates range from 130 km/s to 1,000 km/s. If indeed the Milky Way is moving at 600 km per second, we are traveling 51.84 million km per day, or more than 18.9 billion km per year. For comparison, this would mean that each year, we are traveling about 4.5 times the distance that Pluto lies from the Earth (at its closest). The Milky Way is thought to be moving in the direction of the constellation Hydra, and may someday become a close-knit member of the Virgo cluster of galaxies.
Another reference frame is provided by the Cosmic microwave background (CMB). The Milky Way is moving at around 552 km/s[30] with respect to the photons of the CMB. This can be observed by satellites such as COBE and WMAP as a dipole contribution to the CMB, as photons in equilibrium at the CMB frame get blue-shifted in the direction of the motion and red-shifted in the opposite direction.

They say are universe is expanding at an accelerating rate...
what happens when the rate of acceleration reaches lightspeed?

so, if one were to ever fall into a 'wormhole'...
they would only travel as fast as the absence/negation of the relative speed of this Galaxy, or 486,000 mph.
and even that speed is pathetically slow,
i.e., it would take ~ 1/2 hour to travel to the moon- - If one were able to insert a life support vehicle into a 'wormhole'.
ala' the 'Contact' movie scene

Are we actually moving slower in time because of our galaxies movement through the universe ?
