This is a horrible and intentionally misleading article. They intentionally dupe the reader to imply it's a real wormhole.
The overall EFFECT (emphasis mine) is that of a magnetic
field that appears to travel from one point to another
through a dimension that lies outside the conventional
three dimensions
If anything in the article were like what it was implying this would be world-shattering news. It's entirely lackluster news by comparison. The author should be ashamed for generating this tabloid.
