But there may be an explanation: that the psychological make-up which encourages K-type behaviour worked in the past but is not appropriate to modern circumstances.
One possible explanation for these positrons is the mutual annihilation of the matter and antimatter forms of a type of dark matter called weakly interacting massive particles, also known as WIMPs.
Furthermore, there is an alternative explanation for the "thermitic material" the sceptical scientists found in the dust - it is just a type of primer paint.
