MATT: It is also important to note here (for dhw) that "dark matter" and "dark energy" are terms simply to denote matter and energy that does not emit light...so from what I've gathered, it isn't confirmed "new" or different from other kinds of matter.-Like yourself, I'm totally dependent on what I read, but one area of my sceptical mind reserves the right to question even the existence of dark matter and dark energy, just as it questions the truth of the Big Bang theory. As regards your own comment, here is a quote from a Wikipedia article:-"Dark matter is matter of unknown composition that does not emit or reflect enough electromagnetic radiation to be observed directly, but whose presence can be inferred from gravitational effects on visible matter."-In an earlier post I quoted a revealing comment from another Wikipedia article: "It has been noted that the names 'dark matter' and 'dark energy' serve mainly as expressions of human ignorance, much like the marking of early maps with 'terra incognita'." -You're right that it's not confirmed "new or different". Nothing has been confirmed.
