A new survey looks at galaxies to see whether they are actively forming stars (awake) or not forming stars (asleep). Under commonly accepted cosmology, the galaxies at 12 billion light years distance are seen quite shortly after the big bang 13.7 billion years ago. If galaxies evolve then we expect them to produce stars early on and not so much later.
This is reported in Science Daily.
But what is found is that some galaxies are turned on and some off at all distances. So it seems that galaxies are turning on and off repeatedly. Such a possible cycle would be interesting to cycles researchers.
My personal expectation is that if there is a cycle it is quite likely to fit one of the geological cycles periods such as 586, 293, 146 or 73 million years. Regular walls of galaxies are found in space at close to 586 million light years apart. That combined with the geological cycles fits with the existence of light speed standing waves filling the Universe.
It should be possible to establish for nearby galaxies whether the pattern of asleep and awake galaxies fits with such standing waves.
