The concept of a stationary universe put forward in 1948, Bondi, T. Gold and F. Hoyle. The requirement that the characteristics of the universe in both space and time means that its density, despite the expansion should be constant, and therefore must be continually arise a new substance. "For twenty years – spoke bitterly in 1968, Fred Hoyle, – I have never been able to make my fellow astronomers to understand what is said in this theory – in part, undoubtedly due to the uncertainty of my presentation, but partly also because of the emotional atmosphere, which, unfortunately, has always prevented the discussion of the theory. " Indeed, most physicists and astronomers still refer to the concept of a stationary universe sharply hostile against her, apparently, they say, and observational data.

However, the beauty of this theory is undeniable. Eternally renovating the universe is infinite in time and space, there are no special points (singularity) to replace the fallen stars are coming more and more … Model of the observable universe Einstein – Friedmann, based on general relativity, allow for two types of solutions. According to the first, the expansion The universe will continue indefinitely. In the second version of the expansion is slowed down more and finally replaced by contraction, the red shift will change from blue, first close and then in more distant galaxies. It is possible that after the "singularity" – the state of extremely high density – again to start the expansion. The space in this embodiment, of course, though infinitely – you can not get out of it, finite volume of the universe, of course number of galaxies and elementary particles in it.
