Comfy with a matter universe??

You like the way things develop? Has a certain routine to it a familiar and similar background?  Fairly predictable. Like Matter?

About a decade ago, this author took the deep look into existences. One paper was produced.

Now, another which is an extension of the small essay series of a decade ago, "E= Mc squared-is M a necessity?"

We try to explain our existence through the presence and by the way of M (matter).

Looking more closely:

But for all of the research on the Universe done, is it necessary to have matter in a Universe?

Must a Universe consist of matter? This coarse stuff? 

According to some modern research, like other component factors, the presence of matter is problematic. If certain elements develop stronger or weaker, the Universe

as we know it would not develop. Bosons would not arise, perhaps not even neutrinos which sort of interphase between matter and nonmatter states. If Dark Energy were stronger then nothing could combine as it drives objects apart, along with other factors if different would not allow developments we currently know.  

There, for examples brought forth, be only radiation and no coalescence into matter, or fire (recall the "hell" planet just spotted all aflame), or foam, or whiffs just wind with same result. And other combinations or lack of not commonly considered.

Matter is not even essential in our Universe. Einstein championed matter with a postulate from  Ernst Mach, that to measure the world, one would have to include matter to get dimensions. Willem de Sitter in 1916 computed General Relativity theory to have a Universe with no matter what so ever. Alexander Friedmann, among others, proved that matter is not needed to calculate dimensions of space at all. Space is not regarded as the same. Matter did not have the same gauge as space. Einstein had to concede and drop matter from general relativity. This indicates that matter is not primal for a Universe. Dragan Huterer in 2010 has said, "Space can indeed exist without matter or radiation...But you could, in principle, have an empty universe without observers, or matter or radiation." Other Universe models have been shown likewise that matter need not be included because of other arrangements of elements or natures. Sean Carroll once quipped at a lecture, a universe could form in this room and we would not even know it.

The elements we assume for a universe like ours may not be exhaustive for forming other combinations. When, after some billion years, the stars stop burning due to lack of fuel (hydrogen) there shall be no more matter created. That will likely

be the end and dependency upon it. What will be the universe then be like?
