What is "hubble bubble"

n. (alternative spelling of hubble-bubble English)

Hubble Bubble is a Belgian punk band in which Plastic Bertrand started his career.

Formed in 1973 by Alain Bureau and managed by Bernard Schol, the band released an eponymous album in 1977 in Barclay Records. Plastic Bertrand is listed as a songwriter, singer and drummer under the name of Roger Junior.

The group experienced difficulties following the death of bassist Daniel Massart, as result of an accident while returning from a rehearsal, and after the departure of Plastic Bertrand. The success of the latter will overshadow the group's own success.

The group released two albums: '' Hubble Bubble'' and '' Faking''.

Daggerman Records has reissued both albums.

Nat Records offers the remastered CD.

In astronomy, a Hubble Bubble would be "a departure of the local value of the Hubble constant from its globally averaged value," or, more technically, "a local monopole in the peculiar velocity field, perhaps caused by a local void in the mass density."

The Hubble Constant, named for astronomer Edwin Hubble, whose work made clear the expansion of the universe, measures the rate at which expansion occurs. In accordance with the Copernican principle that the Earth is not in a central, specially favored position, one would expect that measuring this constant at any point in the universe 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.
