And right now, somebody over there is probably looking at the old light of what our own supercluster looked like "back then", and is wondering what our neighborhood might look like nowadays...
An international team of astronomers have stumbled upon the largest and oldest galaxy supercluster found to date, measuring more than four quadrillion solar masses. The formation, dubbed Hyperion, is a giant complex blob of several filaments of galaxies and dark matter. It is thought to have come into being about two billion …
Jack the Ripper is the name given to the unknown assailant, which only works if you are sure the victims didn't mutilate themselves with surgical precision.
Dark matter similarly only works as a stop gap phrase if people would stop insisting it acts from within a galaxy. If dark matter could mean weird matter within a galaxy or something like antimatter acting externally, then the phrase wouldn't be so loaded with potential misdirection.
Had a professor who explained to us an alternative theory that would solve some of the distribution conundrums associated with the Big Bang Theory. The concept was that there were many small singularities of dense matter. One of them exploded (‘banged’), and the resultant shock wave started a chain reaction of other singularities ‘banging’.
It was called the Gang Bang Theory....
I am currently involved in developing new algorithms for faint-object detection in the EU-funded SUNDIAL project, and it is fascinating to see how rapid developments in instrumentation and software is allowing measurements and discoveries to be made that we could only dream of not so long ago. Often the new discoveries throw up more questions rather than they answer, which is of course how science progresses.
Hmm ... 2 billion years after the Big Bang ... that means that it's an "old" image that is ~11.8 billion years old. As someone else mentioned, what does that super cluster look like "today"? Does it even exist anymore? Heck 11 billion years ago our sun didn't even exist.
That is unless the flow of time is not constant ... but that's for another thread :-)
