Space is also expanding due to the mysterious force astronomers call "dark energy". It's an anti-gravitational form of energy that is accelerating the expansion of the universe. According to what I know of the theory, within several billion years, we will only be able to see stellar objects that are located in the Local Group, whose gravitational effects would overcome the anti-gravitational effects of dark energy.

This dark energy is believed to make up approximately 66% of the entire universe. Yet we know almost nothing about it. To say either that the universe is finite or infinite is pure guesswork. We know so little about the universe as a whole. For instance, only about 1% of the universe is made up of "normal" baryonic matter. The rest is dark matter and dark energy, which we know virtually nothing about. We need to find out more about these things before we can start formulating some hard theories about whether the universe is finite or not.

Don't get me wrong, I'm not discouraging debate and stuff like that. I'm just saying that even educated guesses are just that; guesses.
