    If you ever wish me to read your posts, never open one with a sentence in which you qualify an absolute. Correct your post and I shall read it.

    It qualifies as a possibility. I never meant it to sound absolute.

    I seem to recall reading in some news article about a reference to 7 billion years ago, but nothing is said about the 'age' of an 'event' in any of the ARCADE papers submitted for publication. What they measured, if not a experimental error, was a slight increase in the temperature of the cosmic background at around 3 GHz, a radio frequency. An increase in temperature of the cosmic background at that frequency indicates increased emissions (activity) from some source or sources in that frequency range. As stated, the emissions do not come from a point source, but are from all directions sampled. Known sources cannot account for the increase in emissions, thus the mystery "where do they come from?" Here is a link to the papers:

    They said the source was 7 billion years old. It cannot really be interpreted any other way.

    I've been wondering about a theory for the noise. I am wondering whether an interaction between matter and antimatter could have caused such an explosion of noise. A large chunk of matter and antimatter could explode to create a shower of gamma particles, but i am unsure and reside this theory, because i cannot do the calculations required. 6 times the energy of all emissions seems very large, in other words.

    However, recently a massive hole was found in the universe. I speculate maybe the hole was created from a disasterous interaction between ordinary matter and its mirror-counterpart?

    Hypothesis... speculations... and again, simple theories.

    It doesn't matter that you don't know exactly where it came from. Fact is that it is here. So it either came from nothing or it always was.

    Well, there is the arguement itself. If we want a complete and unified theory of physics, we need to ask such questions - if not - we leave the theory as ignorant to answering why.

    Huh ? Look, there is stuff. Did it come into existence or not ? That's the real question.
    Also, I consider the universe itself to be stuff. I don't think you can say that everything came into existence in this or that universe. Where did the universes come from ?

    No, my friend.

    The question of phsyics is evident. We may retain a slight error of ignorance in our everyday lives - but when we are at home studying these things, or in class or even in the lab, to the scientist, these things need to be answered for.

    Philosophical, metaphysical and general theoretical conditions of physics not only break down at a singular point in spacetime, but such question revive from the flames like a pheonix. These questions cannot remain unanswered, because if they are not, that is us looking for an easy path out of explaining them.

    The universes in my model, came from each others references. THEY came from themselves.

    In other words, phsyics right now, cannot say where matter and energy came from. The best the standard inetrpretion can deal with, concering words, is that it came from nowhere. This is unacceptable, in most eyes.

    In other words, from nothing.

    Gluon, It came from nothing, ex nihilo, without cause.

    I don't understand your objection to what must be necessarily true.

    Hmm I feel the best interpretation is that it always was in some form or another.
    I think your theory has a serious logical flaw btw.

    It seems like a logical fallacy, don't you think ?

    It is a logical fallacy to think anything else.

    gluon,
    No, 'they' did not state the 'source' was 7 billion years old, that was your speculation. The source of the peak in the radio wavelength is unknown, all they did was subtract estimated foreground contributions and were left with too strong a signal at that particular wavelength. Since the signal seems to be diffuse and not associated with known nearby sources, it is assumed to arise from the early universe, when the universe was less than half its present age. That doesn't mean the signal is 7 billion years old, it means that the signal, if real and not an error, is at least 7 billion years old, meaning it likely comes from the early universe when galaxies were first forming. Early in their formation, galaxies seem to be much more active than later in their evolution when they are more mature. Quasars and other AGNs were common in the early universe, and if the Big Bang is true, our universe was a much smaller place early in its existence. The signal detected was an excessive hiss of white noise at around the 3 GHz wavelength, not an explosion or something that happened 7 billion years ago.

    If indeed you are right, and energy and space was always in one form or another, then we will have an arguement for an eternal universe without some beginning. So far, this idea in physics remains redundant, because the steady-state universe theory (created by Fred Hoyle) has lost ineterest.

    Good because if it is at least 7 billion years old, my reasoning still stands as pure truth.

    It has got nothing to do with the Steady-state universe theory.
