Re: Are Positrons (anti electrons) the source of Gamma rays?
It's just a question of being careful when using fuzzy words like "explosion". The term generally implies some sort of release of energy resulting in material expanding outwards. That does not describe the BB. Galaxies are flying apart because the space that contains them is expanding, an...

Re: Hadron collider CERN

Well, only an uneducated ignoramus would have that opinion, because it is far from certain scientifically. Ah, so you admit it is POSSIBLE scientifically there...

Re: Are Positrons (anti electrons) the source of Gamma rays?
