Stephen Hawking: "If you took all the energy in the universe, all the particles, even the force of gravity into account and summed it, the result would be zero. It all adds up to zero."
Richard Feynman: "An antielectron appears to be simply an electron moving backward in time. Indeed, a single electron oscillating back and forth in time enough times would generate myriad simingly distinct electrons/antielectrons. They all are in fact, the same electron.
Yanniru: "Because they form one single coherent population all of these would appear to be in an indistinguishable state and hence the system is no more complex than that of that of a single particle wave function in a superposition of states."
Anonymous: "There is an intersting case in quantum chromodynamics whereby one can effectively rotate one family of quarks into another, simply by rotating the elements of the matrix describing the color charge of the quarks. This phenomenon belongs to the symmetry group SU(3), and is why we have three different families (colors) of quarks; it's a three-way rotational symmetry. All quarks are actualy the same quark, rotated differently."
Grand Unified Theory: "The marriage of GR and Quantum Physics, whereby all theories of physics can effectively be derrived from a single simple equation you can wear on a T-shirt."
- Michio Kaku
Stephen Hawking: "To describe the interaction of two particles, you sum the wave functions. So in essence, the universe with all its myriad interactions, is a single gigantic wave function."
Mark: "We're all the same person; the same living universe living myriad lives simultaneously. Treat others then how you would treat yourself, for in essence that's effectively what you are doing ... treating yourself. The principle of Karma ensures that."
