At the Texas Meeting of the AAS this month it was announced that:
1. Nearly every star has one or more planets. Exoplanets/stars ~ 1.6/1
2. Double-star exoplanet systems appear to be not all that rare.
3. Ditto for pulsar-planet systems.
4. Exoplanet systems continue to defy pre-discovery predictions. Big
Time.
Given a minimum of 160 billion bound planets, and given a minimum of
200 billion unbound planetary-mass objects, is the capture of
planetary-mass objects by stellar-mass objects to form exoplanet
systems so unthinkable?
This process, of course, would primarily take place within relatively
dense star-forming regions, so the process is not easy to observe
directly, but the commonality of high-energy jet phenomenology also
taking place within star-forming regions is certainly suggestive.
One safe bet is that the surprises have only just begun.

Holy Sliderule! Take a look at this.
http://arxiv.org/abs/1201.2687
"Nomads Of The Galaxy"
Authors from Kvali Inst. at Stanford, and the U. of Oxford.
"up to ~ 10^5 compact objects in the mass range 10^-8 - 10^-2 solar
mass per main sequence star"
That would be something like =/> (10^11)(10^5) =/> 10^16 unbound
planetary-mass objects. And that's just the planetary-mass population.
Note that Discrete Scale Relativity's 2nd most important and
definitive mass prediction is at 8 x 10^-5 solar mass, which falls
nicely within the putative mass range for the "nomads".
Oh yes, we can expect some big surprises in the forseeable future.
Can you hear me now, ye of little physics intuition?

It is virtually criminal that there is no mention of Mike Hawkins
research, but that will eventually be rectified.
