Life May Be Common in the Milky Way Thanks to Comet Swapping

And Earth may be one of the primary donor worlds.

The sun's random motion through space has brought it close to many other stars over the past 4.6 billion years. These close encounters likely jostle far-flung comets free from both systems, sending them careening toward the passing star, said study author Robert Zubrin, president of the Colorado-based company Pioneer Astronautics.

This "comet swapping" is probably responsible for many of Earth's past mass extinctions, Zubrin found. But the phenomenon has also likely aided life in the bigger picture, helping it hop from island to island across the vast ocean of space, he said.

I always appreciate new and interesting information.  With that in mind, please excuse the following joke:

Where do the Jewish Space Lasers fit in to this scenario ?
