Could is be possible that dark matter is just ordinary matter, made up of atoms and such, and that we just haven't found it yet because it absorbs the radiation we scan for?
Thankyou. I have often wondered the same thing. How exactly can we assume that all non-dark matter is detectable using today's instruments? Isn't it possible that there is one hell of a crapload of normal matter out there that we just can't see? That it isn't some mysterious force that we have to give a spooky name to?
Hope some cosmologists out there can shed some light on this, preferably in layperson's terms.
It is a rewrite and based on the Source engine, which has nothing to do with UT2004.
As are Half Life 2 and Portal, both of which are now playable on OSX.
If you can't understand it, it is intuitively obvious.
