Earth-like planets get life assessment
Fresh models suggest only one planet around Gliese might be habitable.
The most Earth-like planet discovered so far is not quite in the right place to be habitable after all, researchers say. But its neighbour might be.

How Much Earthlike Should A Human-Viable Planet Be? At the beginning of the Universe there was the energy singularity. At its end will be near zero mass and an infinite dispersion of the beginning energy (which might be the beginning of re-evolution towards singularity). In-between, the universe undergoes continuous evolution, consisting of myriad intertwined energy-to-energy and energy-to-mass-to-energy transformations. The cosmos evolution process comprises, though, phenomena of forms of temporary energy storage pockets, of energy dispersion constraints. Examples of such temporary pockets are black holes of all sizes, and all forms of biospheres, if/wherever they are. The temporary constrained energy pockets are far-removed versions, up-fractionally evolved, scattered cosmic fragmants of singularity-akin energy sources. Energy stored in the temporary constrained energy pockets resists dispersion; we do not yet comprehend why and how. However, we comprehend that we, All Earth Life, are real virtual products evolved from Earth's Biosphere energy, for maintaining Earth's biosphere bio as long as possible. Earth's life is a uniquely Earth's Biosphere phenomena, and all species of life - of which presently are known 1.8 million genomes - are interdependent, having evolved from-and-with Earth's Biosphere and doing their task to maintain this Biosphere Bio. Our off-Earth life experience is zero. In our zero experience the off-Earth life survives briefly with umbilical cord to Earth. We do not yet know how much of our womb, of Earth's Life, must be there on another planet for Us to survive there. This is not a simple science fiction matter, but a matter of transfer and growth of some of Earth's Biosphere onto an undefined planet... Dov Henis
