So the moon is supposed to appear the biggest now as it rises low in the sky than any other month in 2007. The news claims that it is a trick of the brain that we perceive the moon as bigger when it is lower than when it rises in the sky because we perceive things as farther away on the horizon. Last time I read that was a theory, not a fact. What I am curious about is if that is true, then why do we all perceive it as biggest this month in particular? Why isn't it just as big all the other months too?
