If I'm to understand properly, Dark Matter isn't tangible. It's not that it's invisible, or that it doesn't reflect visible light, but rather
that items in the vicinity of it react as if
there were matter there, when there's apparently there at all.
Again, I suggest the "paper/magnet/iron filings" example. If all "real matter" is on the side of the paper facing us, and a magnet is underneath
the paper, it's not that the magnet is invisible, or even able to be touched. However, the existance of the magnet can be observed when one dumps
some iron filings on the paper, and watch how they line up according to the polarity.
Now imagine that you had no idea there was a magnet, or indeed that there was even a paper. Your entire ability to perceive the universe is limited to
the observation of things on your side
of the paper. Because of the reaction of the iron filings, you know there has to be something else
there, but cannot see it, touch it, or find it.
Now replace iron filings with hydrogen gas, magnetism with gravity, and paper with background radiation.
Someone suggested that Dark Matter may exist in an alternate universe. This would seem a plausible explanation, and certainly one to keep in mind, but
I believe there might be another explanation, now that I have a better understanding of what Dark Matter, or at least the theory of it, is.
Please keep in mind, I could be totally wrong here, I'm simply connecting Point A to Point B with a logical string.
Waves require a medium (some form of matter) in order to travel from Point A to Point B.
A true vaccuum would be devoid of a medium for waveforms to travel through.
Space is supposedly a true vaccuum. It should not be possible for waveforms to travel through outer space. Yet they do. Light,
exhibits properties of both a wave and a particle. Gravity exhibits properties of a wave as well.
Studies attempting to explain this phenomenon lead to many new theories, such as Zero Point
and some old theories begining to see a new light, such as the New Ether Theory
suggest that there is an "unseen medium" that does actually exist. That space is not truly a vaccuum, or at least not truly empty.
It would appear to me that Dark Matter, New Ether Theory, and Zero Point Energy Fields are all quite possibly related, if not the
same exact entity. So, it may not be that Dark Matter is in another Universe or Diminsion, but rather is more of a...universal "glue" with variable
density throughout space.
Any thoughts on this?
