I have seen some shows on the science channel, going on about how they are saying dark matter or energy doesn't exist. It was more or less thought of
to fill gaps they couldn't explain.
Yes. It's very possible that the dark matter explanation is a "place holder".
Again -- I'm not saying dark matter does not exist, or that science knows nothing. I think scientist do the best with what they know, and at the
present time -- with what they know -- dark matter seems to be a good explanation for what holds galaxies together.
However "with what they know" is the key phrase here. Someday, a refinement to theory of gravity may come along that doesn't require dark
matter to explain things.
Scientist will be the first to admit that what they theorize is based on what they know -- and what they know could be wrong. If you've ever read
books on quantum thoery/relativity/string theory you will know that the author of the book usually says "...although this science may turn out to
be wrong".
Physicist understand that these theories are not "fact", but rather "works in progress".
