If this is the case and its only five thousand light-years away how come we didn't discover it sooner, i dont mean like 20 or so years because we didn't have the technology then, but within the last 5 or so years.
It does make for an interesting point of view though.
perhaps some experts could could share their knowledge
But he added that there was little chance to detect Earth-like worlds in OGLE-2006-BLG-109L because the system was too distant for current techniques to resolve planets the size of our own.

If the universe was a lot smaller than it is, it could be possible to look at ourselves a long time ago. Sort of like sitting in the center of a spherical mirror, and seeing the back of your own . in every direction. This star system is only five thousand light-years away, in our own galaxy. We wouldn't be able to detect planets if it belonged to another galaxy.
So exactly what would the light of our solar system be reflected on?
And if it's 5000 light years away, will it take the light 5000 light years to travel to the point of reflection, then another 5000 to return,? which would make it 10,000 light years in total.
I may be wrong, im just speculating, but all the views are most welcome.
The focus of the new work, which was published last week in the journal Physical Review Letters, was a search of CMB data for paired circles that would have indicated the universe is like a hall of mirrors, in which multiple images of the same object could show up in different locations in space-time. A hall of mirrors could mean the universe is finite but tricks us into thinking it is infinite.
Think of it as a video game in which an object disappearing on the right side of the screen reappears on the left.
"Several years ago we showed that any finite universe in which light had time to 'wrap around' since the Big Bang would have the same pattern of cosmic microwave background temperature fluctuations around pairs of circles," Cornish explained. They looked for the most likely patterns that would be evident in a CMB map generated by NASA's Wilkinson Microwave Anisotropy Probe (WMAP).
They didn't find those patterns.

Now for nablator:What is causing this mirror effect,a black hole you say?That would be evident even with our current technology,also a balck hole does not reflect light,it absorbes light-hence the name "black hole"because light(known),time (theoretically) cannot escape it,it does not bend anything but gravity(and thats why light is absorbed,remember the theroy of realitivity????)-and that in no way creates a "mirror "effect as you say.
****Also I would be VERY interested to see the mathematic calculations(you or someone else has made that PROVES(not some theoretcial statement from a source)our Universe is NOT spherical-you nor your source have no way to prove that statement.Infact most of the newer theroies are suggesting that the Universe IS spherical......once again I will get sources tomarrow as I have class tomarrow-including college Astronomy.
NOTE**In no way am I trying to be a smartass,but I do not like people stating blindly things they know nothing about that contradict all more accepted and logical theroies from PROFESSIONAL scientists.
