Hubble bubble (astronomy) would yield the same value. If, on the other hand, Earth were at or near the center of a very low-density region of interstellar space (a relative void), denser material in a shell around it would strongly attract material away from the centerpoint. Thus, stars inside such a "Hubble bubble" would accelerate away from Earth much faster than the general expansion of the universe. This situation would provide an alternative to dark energy in explaining the apparent accelerating universe. In 1998, Zehavi et al. reported evidence in support of a Hubble bubble. The initial suggestion that local redshift velocities differ
