This is a discussion on English language questions within the Science and Technology forums, part of the Hobbies category; Difference of may and might?
may be / might be
may come/ might come
Is there some sence of use ...
I'm not disagreeing with Joe, they are almost entirely interchangeable, but if you really want to get down to the specifics "may" suggests a slightly stronger possibility of something happening than "might".
More information here, including a joke which might make you laugh.
