    Properties of an evolved universe

    Hello All :) I've heard it proposed that a reason for the fine tuned nature of our universe in a way to allow the existence of complexity and life could be that the universe itself is the product of evolution in a multi-verse. I don't want to debate around the anthropological principle as I am...

    Observational data for evolution of Hubble rate

    Is there any observational data available for evolution of Hubble rate? To give some context, read the dark energy FAQ by Sean Caroll here. He says: "If the universe is decelerating, the Hubble constant is decreasing. If the Hubble constant is increasing, the universe is accelerating. But...

    Why are humans attracted to good looking mates?

    It may not be the general case but this is what it seems from experience. But what's the reason? Do looks indicate health or any other desirable characteristics?
