"Of course he was. The dark energy is coming from our future event horizon. Our future horizon is a 2D spherical shell of Planck thickness 10^-33 cm with us at its center. The area of our horizon is proportional to the total entropy of the universe, with us as (all matter) as 3D hologram computed images projected back from our future light cone's intersection with the horizon. We keep getting closer to our future horizon, but we never reach it in clock time.

Astronomers trying to understand the history of the universe have long thought of galaxies as huge, shiny baseballs. They were flung outward about 13 billion years ago, in the Big Bang; that's why the universe is expanding. But whether they would someday stop and reverse direction under their mutual gravity or keep going forever wasn't clear. To figure it out, two teams of observers decided more than a decade ago to look deep into the cosmic past, by comparing the velocity of extremely distant galaxies with that of closer ones. The farther you peer into space, the farther you peer back in time, and so if the more remote galaxies are flying apart faster than the close ones, that means the slowdown has already begun. If not, it will probably never happen.

To the astronomers' amazement, they found that the universe is actually expanding faster now than it was billions of years ago. It's as though the baseball had a rocket attached. And the only plausible explanation was that some mysterious, invisible source of energy must be pushing the universe apart faster and faster all the time.
