    Yes, the rate at which supernova occur in our galaxy. That's about 2 million times since it was formed.

    This is the youngest known supernova in our Galaxy. It was hidden in dark dustlanes near the core. Any such supernova on the other side of our galaxy are even harder to see, there are likely several others younger than this that have not yet been found(and our current equipment is capable of finding them). Our galaxy can be expected to have an average of three every 100 years.

    This is an image of two groups of Red Supergiant Stars that are considered ticking time bombs(they too are much nearer to the core). Whether they start popping off in the next few years or 200 years from now, they will go fairly soon(in stellar terms).

    And this is Eta Carina, it hasn't yet exploded(believe it or not)but it's getting steam up, so to say.

    Once again, you appear to have great difficulty wrapping your brain around the CMB scope/data. It doesn't get much simpler than this...

    Logically speaking, you cannot get or have anything if there is nothing.

    But if you bend the definition of nothingness in such a manner that it is actually something (e.g. empty space), then sure, you can get "something from nothing".

    I have neither the time nor the inclination to tutor you on the CMB. Try this avenue which should be available at any public library system. John Mather was the project scientist for COBE.

    I have talked to people at NASA about a yr ago or so , and he told me they can only eliminate 4 to maybe 5 galaxies as being the source of the micro waves

    inotherwords the only way your goin to get a true picture of CMB is to eliminate all galaxies in the Universe

    so as I said the CMB picture is local

    NOT

    it is true , phone them yourself

    and if you do , ask them how many galaxies they can eliminate as the source of microwaves

    Talking to a janitor at NASA does not count as talking to NASA.

    The CMB is homogeneous across the entire universe. If galaxies were the source, it wouldn't be.

    Nor would it's black body spectrum match exactly what the BB theory predicts it would be.

    But it does.

    Phone NASA? Who did you talk to, the public relations secretary? (If anyone).

    Don't need to ask them they have the source of the CMB all over their websites.

    Cosmic Microwave Background is not local, it is of a different frequency and is too uniform to be of a discrete origin. And anyone who told you differently who works at NASA should be fired for gross incompetence.

    details , details thats the key

    what sources of CBM did they eliminate , 4 to 5 galaxies thats all

    they would know better than you

    when I mean local I mean 4 to 5 galaxies at the most

    sure but what they don't tell you is the sources of CMB that are NOT eliminated

    thats the key
