has nothing to do with a blind date's face.  Dark matter aside, they actually think that there is a property of the void itself that is accelerating the rate of the expansion.  Even stranger, "they" (you know who you are) think there is enough energy in the void to power a warp type propulsion drive.  I'm deliberately stopping here w/o further elaboration.  We don't want to end up on the secret provider site with "Nerd" next to our names, do we??
