A new theory may explain the mysterious force that is causing our universe to expand at a faster and faster rate. Could a neutrino — an electrically neutral and nearly mass-free sibling to the electron – have triggered dark energy, the anti-gravity force discovered just over a decade ago? That’s the latest idea from a team of theoretical physicists who suggest that dark energy was created from neutrino condensate in the split second after the universe’s birth 13.7 billion years ago. The idea sprang from calculations showing that the density of dark energy is comparable to the value of neutrino mass, said lead researcher Jitesh Bhatt, with the Physical Research Laboratory in Ahmedabad, India. Dark energy, an unknown force that is accelerating the expansion of the universe, is the leading cosmological mystery of modern-day science. It was discovered in 1998 after astrophysicists noted that supernovae — the exploded remains of massive stars — showed an accelerated rate of expansion in the last 2 billion years or so when compared to older epochs. Explanations for dark energy fall into two basic camps: those theories that add a new physical entity or those that change the laws of gravity, said Eric Linder with the University of California at Berkeley.

I am in the "new pysical entity"camp and one day soon we shall destroy those evil "change the laws of gravity" naysayers once and for all!!!!!!1
