A bunch of galaxies all headed in one direction, and that direction just over the horizon of the visible universe, have got astrophysicists wondering if there’s some giant mass lurking out there.
The renegade galaxies show up against the cosmic background radiation -presumably a remnant signal of the Big Bang – as they’re moving in a direction opposite to that of the expansion of the rest of the universe.
So, what’s causing this unprecedented flow of galaxies towards one point(that point, for those of you familiar with the night sky, is in the apparent vicinity of Vela, part of Argo Navis, prominent in the Southern skies)?
We don’t know, but that’s not going to stop us theorising.
Best guess so far involves an enormous mass lurking around the edges of the universe.
Well yes, that would do it, wouldn’t it? Huge gravitational source pulls entire galaxies towards it at speeds in excess of 1000km/s.
At the University of Oslo, Hans Christian Erikson has been uncovering similar forces – large, so far invisible structures which could signify the existence of sodding enormous masses built into the structure of the universe which we just haven’t seen as yet.
If nothing else, this makes you wonder just how much, and of what significance, we have failed to notice about the space time in which we are embedded. My bet would be quite a lot.
