I understand that electron is made up of leptons which are made up of energy. But what I don't understand is that how can leptons be just made up of energy, I mean its not like a balloon. Another thing is that Wikipedia claims that Leptons and Quarks are the only 2 fundamental particles...but then what is neutrino made up of? What about antineutrino? I understand that this universe is made up of energy but then why is it moving?(why are the electrons spinning and rotating?) Don't tell me b/c the entropy is increasing b/c then I'll ask what caused the big bang. If like Hawkins, you say it is a cycle, then are you telling me time never began?
