“The problem here is that a civilization that is 1,000 light years away doesn't know we exist. They don't know that we have radio telescopes here on Earth because they see Earth as it was 1,000 years ago. Nothing can travel faster than light, so however good their instruments they can't see in affect the future. So there is no particular reason they should be sending us messages at this time.” KnowsShouldYearsReasonProblemLightEarthParticularCivilizationMessagesYears AgoInstrumentsRadioFasterTelescopesLight Years Author:Paul Davies

“The wealth of any ecosystem is its perennials. The primal herbivore-predator-disturbance-rest dance is literally the breath and pulse of the earth. Grasses recycle oxygen far more efficiently than trees. The turnover is faster. Grass reaches out and turns solar energy into carbon. Tillage hyper-aerates the soil, burning out carbon. But because a plant creates bilateral symmetry at the soil horizon, it sloughs off root mass when the top gets chopped off.” EarthTurnsEnergyWealthTreeMassRootsBreathsPlantBurningFasterGrassSoilHorizonReach OutCarbonOxygenPulsePrimalEcosystemsPredatorDisturbanceSymmetryHyperSolar EnergyTurnoverSlough Author:Joel Salatin
