the amount of dark energy changed randomly from one island universe to another

Within a decade, however, this edifice had crumbled. The resolution of Kelvin’s “details” unleashed two full-scale revolutions, of relativity and quantum mechanics. What’s more, each of these revolutions took physics in a radically different direction,

we see atomic spectra, but we weigh hadron spectra.

The equations we devise to explain the unexplored or unknown have to make “sense” to our left brain’s way of thinking and perceiving. If it does not make sense and fit into our closed loops of reality, then we will just chop pieces off until it does. You cannot imagine how many times this has happened in the history of physics.

In such a scenario all antimatter would subsequently have annihilated itself with matter in the dense primeval gas, inundating the universe with high-energy photons. But there would be a small relic of matter left, no more than one part in a billion, which, almost as an afterthought, would make up the roughly 1050 tons of matter of which you and I

if instead we assumed we are randomly selected among the much larger ensemble of observers inhabiting island universes differing both in their cosmological constant and in the size of their galactic seeds, then the predicted value of λ would be a thousand times larger than what we measure.[7]

The universe at the end of inflation must have had an extraordinarily low entropy
