Bacteria can grow under extreme gravity: study
Date: 2.5.2011
A new study in the Proceedings of the National Academy of Sciences shows that bacteria is capable of growing under gravity more than 400,000 times that of Earth and gives evidence that the theory of panspermia could be possible.
While the bacteria clumped together in pellet form when the gravity increased, their growth rate was not affected. Two of the species, Paracoccus dentrificans (soil bacteria) and Escherichia coli were able to continue growth within a gravity rate of 403,627 g.
For example, the gravity on a brown dwarf has been estimated at around 10 to 100 g. While it wasn't believed that life could grow under those conditions, this study shows that is not the case.
