    An essay way of picturing what john is saying is. Imagine an atom expanded to the size of a football field where the track running around the out side equals the orbit of the electron. The nucleus of the atom would be about the size of a grain of sand. This leaves plenty of room for cosmic radiation to pass through your body with out hitting any thing.

    Thanks for explaination. But I want to know that when we say cosmic ray/radiation hitting us on earth, these are primaries or secondaries.

    Im sure both can. Secondaries will have less energy though.

    John, But when we say cosmic rays practically not hitting us on earth--these includes both primaries & secondaries or we just consider primaries. I just want to know that if secondaries are hitting us in substancial quantity or not? Whether these are harmful or harmless is a secondary question.

    They are just as harmless as they are much less energetic...similar to normal background radiation.

    blackholesun, but how much they(secondaries) are hitting us?

    Not much as most the upper and lower atmosphere absorbs most of the secondary. Some of the mesons do make it to the gound. In fact this process was used to validate special relativity because the half-life of mesons is pretty short. The fact that some were making to the ground from that for up made the case for time dilation was affecting those mesons that were moving at relativistic velocites.

    Why are u so interested in the details of exactly how many secondaries hit us Kumar?! R u gonna do a detailed statistical analysis of how many mutant people should be walking around the earth as a result of secondary mesons?

    John, I just want to ensure/assess Cosmic effects as mentioned in spritual systems. If secondaries with lesser energy are hitting us in substancial quantity regularily or sesonally, we may have assess their beneficial or harmful effects on us.

    But we have already discussed that they are not harmful in the everyday quantities!

    It is ok, but what is their(secondaries) everyday quantity hitting us?

    I have no idea. Im sure it might not even be possible to get even a fairly accurate estimate anywhere since it means nothing to most people! Unfortunately, sometimes, scientific research only follows the most productive (which ususally means money) paths.

    John, thanks. It may mean that possibility for 'spritual cosmic effects' is still there as secondaries are low energy particle which may not damage but may provide some short of energy.

    Well, let's face it - there is certainly more within the human mind and body than medical science has described. If you wish to believe in spiritual or physcological effects of cosmic radiation, no-one can disprove your belief; but others may choose not to share it, unless you can provide proof.

    Cosmic rays are part of background radiation, what effects they have on use is debated. Low-level radiation might be beneficial as it cause DNA repair mechanism to stay active.

    Cosmic rays are not the same as back ground radiation. Back ground radiation is caused by the large amounts hydrogen in our universe. This hydrogen is left over from the big bang. Cosmic radiation is produced by stars. And the suns rays are strong enough that they penetrate many miles in to the earth.

    optic,

    What kind of bullshit is that?

    perhaps you could explain your theory better?

    Hi optic, and welcome to the forum.
    Don't worry, we're not all gutter trash here.

    Fetus,
    What optic is saying is:
    • Background radiation (CMBR) is low-energy microwave radiation radiated from hot hydrogen not long after the Big Bang.
    • Cosmic Rays are high-energy particles that come from many sources in space (the Sun, Supernovae, Quasars, etc).
    • Cosmic Rays (including those from the Sun) and the remnants of cosmic ray collisions in the atmosphere can reach deep underground.

    Good I’m glade. If these people would read scientific American they would know these things.

    Sometimes I wonder if they are arguing science or the English langage.

    Hydrogen is the most plentiful element it makes up 90% of all the atoms in the universe. This is because it takes the least amount of energy to form. Many The heaver elements in the universe have to go through star formation before they are created

    After the big bang there was a period when the universe was so hot that nothing could bond together it was astutely plasma. This plasma was so active and so hot that light didn’t exist. Once the universe started to cool photons, quarks, neutrinos, baryons, and electrons formed. Than slightly later the quarks began to bond together to form protons and neutrons. As the universe cooled slightly more the electrons began to orbit the protons most of these only had one proton (hydrogen) some had two (helium) and a few had three (lithium).


    In 1948 Ralph Alpher predicted that if the big bang happened there would be huge amounts of hydrogen left over. Hydrogen produces radiation. If there were actually large amounts hydrogen left over in the universe than there would be a constant flow of radiation reaching earth. This was first observed in 1950. And later confirmed 1n 1965.
