Why Are You Alive - Life, Energy & ATP

Sources & further reading:
At this very second, you are on a narrow ledge between life and death. You probably don’t feel it, but there is an incredible amount of activity going on inside you. And this activity can never stop.
Picture yourself as a slinky falling down an escalator moving upwards - the falling part represents the self replicating processes of your cells, the escalator represents the laws of physics, driving you forwards. To be alive is to be in motion but never arriving anywhere. If you reach the top of the escalator there is no more falling possible and you are dead forever.
Somewhat unsettlingly, the universe wants you to reach the top. How do you avoid that and why are you alive?

    • @Subhajit Sahu Yes, they indeed are! ATP is an acronym for "adenosine triphosphate" and that "adenosine" contains the DNA/RNA base adenine which is usually abbreviated with A. The related substance GTP is basicly the same thing but with guanine (G) instead of adenine.

  • If above is true then what is point of life?? what is point of having consciousness?whats the point of anything?? even cells are made of "atoms" and "atoms" as "individuals substances" don't have life/consciousness. Basically if living things are made up of dead things, what is life, what am I?? what are you??. What is the point of existence??.

    ali ahmedali ahmedDag siden
    • @Huỳnh Hải We cannot create our self's, even our children will have different consciousness then us. We are not looking into something..... or we are trying to avoid a certain possibility, Energy neither can be created nor lost, it transformers form one form to another. A consciousness build from several experiences, my perspective will be different from yours and yours form mine. So my consciousness is different from your's. you exist in a universe where your "center of your universe" and I where "I center of my universe'. Your are like an molecule so am I, when we interact we create we evolve a new taught, which influences your consciousness and mine in a way it impacts every around us. We all leave information, but for whom and for what??. we die but the information remains in the universe till it exist it means we truly have never left existing.

      ali ahmedali ahmed11 timer siden
    • The purpose of life is to make more life. The point? There’s no point but ones we create for ourselves. It’s a waste of time to question the meaning of existence, because there is no meaning but ones you have created yourself.

  • I just want to point out that there's nothing *inherently* special about life, complex as it may seem. We just happened to be one of the few planets where such a reaction occurred to evolve into life as it is. There may have been other forms of life, but they died out because of limited changeability.
