sciencehabit writes: Scientists have known for several years now that stars, galaxies, and almost everything in the universe is moving away from us (and from everything else) at a faster and faster pace. Now, it turns out that the unknown forces behind the rate of this accelerating expansion - a mathematical value called the cosmological constant - may play a previously unexplored role in creating the right conditions for life. That is the conclusion that a group of physicists who studied the effects of massive cosmic explosions, called gamma ray bursts, on planets made. They found that when it comes to growing life, it's better to be far away from your neighbors - and the cosmological constant helps thin out the neighborhood.
