    If we have alot of cells would a much larger creature be more sensitive to pain?

    Single cell organisms probably don't feel much at all considering the simplicity of their internal systems. Humans with our big brains can feel pretty bad quite often.

    If you had a larger planet (definitely possible in this huge universe) would a creature with a brain 1000 times bigger be more sensitive to pain? Would this creature seem extremely bipolar due to going from extreme highs to extreme lows?

    I equate the amount of cells with sensitivity and complexity in interpretation of the reality around that creature.

    You have a habit of raising interesting questions.

    Point 1, in the "for what it's worth" category: The bigger the planet, the stronger the gravity. The stronger the gravity, the more resistance against movement an organism will experience. Gravity beyond a certain point (don't ask me) is probably counter-productive for large organisms.

    More nerves, more pain? Well... where are the nerves? Our brains, with at least 100 billion neurons, probably more, feel no pain -- themselves. Our brains interpret pain signals from elsewhere in the body. It does make sense that the larger number of pain nerves that are stimulated (by injury) the worse the pain will be. There are limits, sometimes.

    Distraction can enable us to ignore pain (provided it isn't too severe, too long lasting). Other sensations, such as cold, can swamp pain (which is why putting ones slightly burnt hand in cold water reduces pain). Acupuncture, hypnotism, relaxation and meditation techniques can reduce pain.

    Severe burns are so painful because many layers of tissue (all with pain receptors) are affected. Shingles is very painful when the varicella-zoster virus is very active inside nerve cells. varicella-zoster virus (chickenpox) can cause shingle pain for years. (The chickenpox vaccine does not cause shingles.)

    FYI, there are separate nerves for pressure, itching, and for pain. Itching can also be quite severe.

    Finally, pain nerves can stop functioning. Diabetes can cause peripheral neuropathy, where the diabetic no longer feels pain in their extremities (feet, hands) and may not notice injuries that can lead to severe infection.

    interesting. I knew a guy working on a miniature blimp (as opposed to a full sized blimp) and one of the things he discovered is that when you shrink the blimp you have to change the blimps shape. He speculated the reason was atomic and sub atomic particles are a certain size so when you decrease the size of the blimp you have to change the shape also (to make the blimp still be effective).

    A blimp is a helium filled cigar shaped aircraft.

    I wonder if this concept would apply to giant humans or mini humans.
