Missing matter...
The quantity and types of matter and energy in the universe have in recent years been a subject of much debate, criticism and resentment. A film was made about this topic balancing coverage between the brilliance of the minds envisioning dark matter as a means of reconciling the missing mass of the universe, and the egos that would suppress public discussion of such topics. Short of a full-blown spoiler, let's just say it doesn't end nicely.
https://en.wikipedia.org/wiki/Dark_Matter_%28film%29

An interesting article was just published on a first ever observation of a "fast radio burst" that gave a unique opportunity to measure the distribution of matter and energy to compare it to currently generally accepted expectations of 70% dark energy, 25% dark matter and 5% 'ordinary' matter (the matter that makes everything we see). The observations were consistent with this theory, however, through observations of stars, galaxies and hydrogen, astronomers have only been able to account for about half of the ordinary matter, the rest could not be seen directly and so has been and continues to be referred to as 'missing'.

@Banana Breath,
I pose myself that question when I was 16 or so. Where does the Universe expands to if there is nothing to nothingness, and after reading Einstein it come to me that perhaps the whole of spacetime is already settled, no actual true motion whatsoever is happening...from there I jumped to Parmenides and realized how actual his point on Being is still central in our search for understanding the world around us..

What kind of motion makes sense to have and what kind it does not ?

This is a central question that I never saw properly addressed neither by cosmologists physicists or even Philosophy of Science.
Motion into nothingness certainly doesn't make any sense, as there is nothi nt to move into. From this simple straight forward conclusion it follows the Universe is either a part of a multiverse where the same question
arises, or that as a whole the Universe has boundaries and must be rational, that is to mean finite.
In this context motion is an on/off "reader" of that which already is throughout the whole of spacetime, and that is where our sense of change comes from.
This finite cyclic Universe must therefore have a pattern where the "end" meets the conditions of the "beginning" and repeats forever...another variation of this idea is that each cycle has slight changes in the conditions that themselves for a meta algorythm where X number of cycles produce all possible worlds within the "Rubik's cube of this discrete X size space that goes back n forward between big bangs...
In sum I am no cosmologist, not even a professional philosopher but I have a very clear idea of what can't be the case. An irrational boundless ever expanding Universe going forward into nothingness doesn't make any sense.

Whatever is the case the Universe or Multiverse are a complete unified reality where time and motion can only operate from within the system. That is to mean they are not of first order reality. Parmenides has a point.
