I was doing online physics homeworks like a good little boy.

And I stumble upon this beauty of a question.

i think he was trying to show off answer D not that he needed help

hmmm.... Well its either C or D hmmm....


the answers actually B

On multiple choice questions it's always best to write down E: and make up your own.

Not D and not C it can' be A, since it is known that alpa particles cant 'create' dark matter, so I wouldgo with B ... but then again I'm an econ major whose only background in science is a couple astronomy classes I took last year ...

All i know is that it's B. All the other ones but A don't make sense, Which isn't possible.

Wait, are you being serious?

E = MC2.

Nuff said.

It is quite clearly D.

Answer is obv E......if Maas is in the equation he is either on your side or not =) up to you to figure which lol
