    What is alive? What are the observable necessary physical requirements for an entity to possess life?

    Is the planet earth a large living organism? Are plants individual living organisms, or are they limbs of the earth? Their inability to move or walk independently like animals or insects implies an absence of any sort of free will.

    If plants and the planet are living organisms, what do they respond to? How do they sense? Plants seem to respond to light, heat, and some have even argued that they can respond to music and even just emotional vibes.

    Is a star alive? Could it be conscious? Is it a singular, independent consciousness with independent will? Does it have intelligence? Could it have a mind that works through the electrical currents? Can the sun and/or the earth make conscious, intentional physical manifestations, such as earth quakes, solar flares, etc? Can they also be subject to involuntary reactions in perseverance of the physical, such as a human being throwing up after eating bad pork chops? What would the sensation of time be like for these large creature?

    Discuss? :cool:
  2. life = ability to utilize energy and reproduce
  3. Stars do reproduce. The process and length of time, I don't know the details of, though I'm sure there's something written up somewhere by someone about it.
  4. The reproduction of sea stars:

    Sexual: Males and females release their gametes into their environment. Those that meet up with gametes of the opposite sex result in fertilized embryos, which become part of the zooplankton (eggs and larvae from other animals, small protozoa and crustaceans) as they begin their development. Later they settle down at the ocean floor as fully developed adults.

    Asexual: Sea stars are also able to reproduce by fragmentation - that is, new sea stars can develop from broken off arms.

    The reproduction of space stars:

    A star is formed out of cloud of cool, dense molecular gas. In order for it to become a potential star, the cloud needs to collapse and increase in density.

    You can look through these books and instructional materials from for more information about stars.

    There are two common ways this can happen: it can either collide with another dense molecular cloud or it can be near enough to encounter the pressure caused by a giant supernova. Several stars can be born at once with the collision of two galaxies. In both cases, heat is needed to fuel this reaction, which comes from the mutual gravity pulling all the material inward.

    What happens next is dependent upon the size of the newborn star; called a protostar. Small protostars will never have enough energy to become anything but a brown dwarf (think of a really massive Jupiter). A brown dwarf is sub-stellar object that cannot maintain high enough temperatures to perpetuate hydrogen fusion to helium. Some brown dwarfs can technically be called stars depending upon their chemical composition, but the end result is the same; it will cool slowly over billions of years to become the background temperature of the universe.

    Medium to large protostars can take one of two paths depending upon their size: if they are smaller than the sun, they undergo a proton-proton chain reaction to convert hydrogen to helium. If they are larger than the sun, they undergo a carbon-nitrogen-oxygen cycle to convert hydrogen to helium. The difference is the amount of heat involved. The CNO cycle happens at a much, much higher temperature than the p-p chain cycle.

    Whatever the route – a new star has formed."

    How Does a Star Form?

    The base method of reproduction is the same, no? Crud released from stars (chemical gases) meet together and form new stars... very similar to the reproduction process of sea stars in theory.

    Curious, no?
