POPSInvisible hand in invisible matter. Dark matter might not exist. Dr Famaey added, "If we account for our observations with a modified law of gravity, it makes perfect sense to replace the effective action of hypothetical dark matter with a force closely related to the distribution of visible matter." The implications of the new research could change some of the most widely held scientific theories about the history and expansion of the universe. Lead researcher Dr. Gianfranco Gentile at the University of Ghent concludes, "Understanding this puzzling conspiracy is probably the key to unlock the formation of galaxies and their structures." What about NASA's direct proof on dark matter's existance? Broken study? This is actually makes sense, but so far is a little hard to accept. Does anyone have any ideas about this?

POPSFirst extra-galactic planet spotted in Andromeda The advantage of microlensing is that it works best for more distant objects so it's ideal for planet hunting in other galaxies. In theory, it should be possible to see Earth-sized objects in this way. The disadvantage is that microlensing is a relatively rapid, one-off event that lasts a few days at most. That makes observations difficult to verify. And today a new analysis from Ingrosso and co shows that this companion has a mass about 6 times that of Jupiter. That's heading into brown dwarf territory but it's also well within planetary territory too.
