The text proposes that neutrino oscillations inside planetary matter are responsible for the fabrication of new protons, neutrons and electrons. From this, hydrogen nuclei are likely to form at the core of dense rocky planets. Slow neutrons produced from the oscillation of neutrinos inside dense matter, may be fused into atoms near a planet's core. This will result in new elements production within a planet.

Ridiculous. Neutrinos can't form baryons spontaneously; it violates several conservation laws. But even if we assume they can, they can't do it unless their energies are greater than 1 GeV (the mass of the neutron) in principle, but in practice the energy would have to be much greater than that, because it has to be above 1 GeV in the rest frame of the collision, not in the Earth's frame. But that last point I also waive.

The fact of the matter is that the flux of neutrinos with energies greater than 1 GeV is vanishingly small. That excludes any neutrinos from any star or supernova, or even relics from the Big Bang. All that is left are a fraction of the neutrinos from Active Galactic Nuclei. Think about how little light the Earth receives from AGNs, and you'll have a rough idea of how few neutrinos that comprises.

But how much energy would we need? Well, these...individuals...are claiming that MOST of the mass of the Earth came from this process, so let's suppose that all of it was created this way. Since the neutrinos aren't enough, let's suppose that every erg the Earth receives from the Sun gets converted to energy.

The Earth has a mass of 6x1024 Kg. That translates to 5.4x1041 Joules of energy.

The Earth receives 2x1017 Watts from the sun. A Watt is one Joule per second.

That would take 2.7x1024 seconds.

There are 3x107 seconds in a year.

Therefore, it would take 9x1016 years to build an Earth this way. The universe is 1.4x1010 years old. So it would take six million universe lifetimes to build up the Earth in this way, but that's if you use the total output of the sun. (Or rather, a series of ones like it. A star like that only lasts 10 billion years.) If you're depending on high-energy neutrinos, it will take gigantically longer.

D'oh! I meant converted to matter.
