I am sorry but you're are mixing Dark Matter and Dark Energy. You're right about the quantity of dark matter in our Universe, but it actually is known because of its gravitational effect - not the opposite. I am not sure about this "repulsive gravitational effects". But dark matter shall not be the responsible, if it exists. In fact, it's the dark energy that does it, but as if the "outside" of the Universe was pulling matter in all directions, accelerating the expansion and eventually tearing everything into infinite pieces - even the atoms. This would be the most radical Big-Rip theory. Keep it up! Well, I agree with most of your explanation, but not all. I am sorry but you're are mixing Dark Matter and Dark Energy.

Entanglement is pretty cool too.

Now, I have to make a pitch here for Astronomycast (http://www.astronomycast.com/) an astronomy podcast that I follow where they talk about some really cool astrophysics.

OK, back to preparing a presentation I have to give tomorrow. Carry on.
