Aliens could be the size of bears.

Fergus Simpson, a cosmologist at the University of Barcelona, has claimed extra terrestrial's could weigh an enormous 700lbs.

According to Livescience.com, Fergus has published the argument based on the statistical model called Bayes' theorem, which works from the premise that life can only be supported on planets the same size - or slightly smaller - than earth.

The relation between the size of the planet and its population can then be plotted on a curve against probability, which predicts that the median weight of an alien would be about 692 lbs.
