Galaxy without stars

Galaxy without stars and containing only hydrogen gas is the newest strange finding of astronomers (see this). The proposed explanation is that the galaxy-like structure is so young that the formation of stars has not yet begun.

The hydrogen galaxy might be also seen as a support for the TGD based view of the formation of galaxies and stars. The basic objects would be cosmic strings (actually 4-D objects as surfaces in M^4xCP_2 having 2-D M^4 projection) dominating the primordial cosmology. Cosmic strings would carry energy as analog of dark energy and would give rise to the TGD counterpart of galactic dark matter predicting the flat velocity spectrum of distance stars around the galaxy. Cosmic strings are unstable against thickening producing flux tube tangles. The reduction of string tension in the thickening liberates energy giving rise to the visible galactic matter, in particular stars. This process would be the TGD counterpart of inflation and produce galaxies and stars. Quasars would be formed first.

One can however consider a situation in which there is only hydrogen gas but no cosmic strings. If the hydrogen "galaxy" has this interpretation, the standard view of the formation of galaxies as gravitational condensation could be wrong. Galaxy formation would proceed from short to long length scales rather than vice versa.

See the article About the recent TGD based view concerning cosmology and astrophysics or the chapter with the same title.
