Re: misleading nonsense about fantasy matter (Score 2)

I'll mansplain it 4u: The intergalactic void is not at 0K temp. So, there's some energy there. Since it's so vast, there's pretty much energy. Now and then, this energy is quantized into a photon buzzing off in some direction. These photons sometimes disappears into the void again, or goes on and will eventually push on a galaxy. This stream of EM radiation is anti-gravity (also called dark enery). What we usually call gravity is the abscence of this radiation, its shadow. The pictures they have produced shows this shadow between galaxies. Such shadows is also what keeps the moon in orbit around the earth and the Earth in orbit around the sun. The need for dark matter comes from the fact that this field (anti-gravity) is weaker inside the galaxy where we are and can measure it. It's much stronger at the outskirts of the galaxy where it hits at full force. Comprende? :)
