The expansion of the metagalaxy

  • Björn Bonnevier
Letter to the Editor


In the big-bang hypothesis the metagalaxy (or Universe) is considered to have expanded from a state of extremely high density. The observations of distant galaxies are usually interpreted with this picture in mind. As pointed out by Alfvén it is important to see, if these observations do really require the hypothesis of an early extremely high density. It is found that with present available information, it is not possible to conclude that the density has been higher than implied by the Schwarzschild limit.
