The inference is that outer space has a higher density level of plasma - or that is the thinking of researchers in a paper in Nature Astronomy (Nov 2019) - although one might argue it is the bubble around the solar system that is dense (I suppose). There is definitely a boundary at the outer reaches of the solar system - as experienced somewhat earlier when Voyager 1 passed through.

I quite like this one. At https://phys.org/news/2019-11-planck-space-observatory-universe-sphere.html ... researchers from the universities of Manchester, Rome and Paris have sparked a debate amongst cosmologists by claiming data from the Planck Space Observatory suggests the universe is a sphere - it is not flat (or oblate like a pizza on a plate) as most cosmologists have supposed -as at Big Bang light expanded out in a straight line (or lines). The findings are published in Nature Astronomy (see https://doi.org/10.1038/s41550-019-0906-9 ... ).

The prime stage of occupation dates back to the Mycenaean era (LB age) and it was destroyed in a spectacular conflagration - or that was the considered opinion of archaeologists during an earlier excavation. This aspect is left unmentioned (in the press release at least) but it is worth bearing in mind as many other Mycenaean cities and towns were subject to destruction at the same point in time.

Scientists are expanding the universe it would seem - via state of the art technology and technique. See https://phys.org/news/2019-11-scientists-refine-quickly-universe.html ... what we have is another measurement of the Hubble Constant - recently made uncertain by several studies that have come up with different rates of expansion. The concept of an expanding universe was put forward by Edwin Hubble in the early 20th century. He found that galaxies were moving away from each other - so the story goes.
