OK so we all know how it goes, Pokemon magically appear from their pokeballs and fight it out, but when they re-enter Pokemon trainers seem to have no trouble lifting the balls up (I mean some Pokemon are pretty heavy; Charizard for example is a right burger biffer). So where does the weight, and therefore mass, of the Pokemon go? In search for an answe myself and an equally socially challenged friend have come up with two possible theories, which continue a longstanding tradition of debate and hate towards each other:

1. Inside the pokeball is void of Higgs Bosons, therefore the Pokemon does not experience mass as it has no interaction with the Higgs Field. I'm assuming the pokemon turns into a strange radiative state which is regenerated on expulsion from its resting place.

2. (In what is quite franky a rediculious explanation..) The Pokeball acts as a gateway to a different dimension which stores the Pokemon until needed (I know, down right retarded).

So, Discuss.
