particle physics - If matter and antimatter were produced equally during the big bang, where is the rest of the antimatter?



As far as my understanding goes, during the 'Big Bang' equal amounts of matter and antimatter (matter's oppositely charged twin) were produced, and the physical matter that remains within this universe is what's left over from the equilibrium of matter and antimatter canceling one another out following the Big Bang. If matter and antimatter truly do cancel one another out (are transformed into pure energy) upon contact, than:


a) why is there still matter in existence?


b) if matter is still in existence then doesn't that mean that somewhere within the universe there is an equal amount of antimatter?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
