Not a physicist. If napkin calculation goes, that's 1000 Jupiters per star. Is that really improbable? There is a lot of space outside of solar system radii.

- antognini 8y agoI think it would require more like 10,000 Jupiters per star to account for dark matter in the Galaxy. The issue is that these microlensing surveys put an upper bound on the number of rogue Jupiters that can be floating around and this bound is much less than 10,000 per star.
- Eesais2e 8y agoCan microlensing account for the whole continuum of black hole sizes that might be floating around in the galactic halo?
