I didn't really understood in which way this is a "portal". Is this a clear, magnetized path, like a sudden "highway" from sun to Earth; or are we talking about portals like Portal, the game? Neither this nor the NASA article [1] really explains what's happening. I think it's more like a "highway" or flux tube [2] but I'm not sure at all.

It seemed to me like the writer was conflating completely different concepts, perhaps without even realizing it. I'm sorry I wasted 2 minutes of my life reading this drivel.

By the NASA definition, a portal is an unbroken magnetic path between the earth and the sun. No instant transmission of anything is happening.
