Today on Boing Boing Gadgets we looked at an inexplicable, gravitationally-defiant watch and discovered that Malia Obama uses a cute little Kodak digicam.
Even so, there is some question whether a mass of that magnitude could possibly affect us gravitationally.
The gas-giant planets would remain gravitationally impossible for human life, but not their moons.
This apparent acceleration in the expansion of the universe has typically been explained by postulating the presence of gravitationally repulsive 'dark energy'.
The dimness of those stars might mean that Earth-sized worlds in their habitable zones orbit so close to the star that they become gravitationally locked so they always have one face perpetually looking onto the star and potentially baking.
