Krauss and Chaboyer came to the conclusion that the universe is expanding more quickly now than it did in the past.

Thanks for the ping.

I'm still trying to comprehend the above statement. I should have taken more math.

That last paragraph:

The only explanation, according to Chaboyer and Krauss, for an accelerating universe is that the energy content of a vacuum is non-zero with a negative pressure, in other words, dark energy. This negative pressure of the vacuum grows in importance as the universe expands and causes the expansion to accelerate.

It has an eerily Barry-Setterfieldian "more energy is periodically pumped into the universe from the vacuum, thus violating conservation of energy" kind of ring. I hate it when the loonies get something to lawyer with.
