http://science.nasa.gov/headlines/y2...alienearth.htm This picture really puts things into perspective. When I look at that picture I try to imagine myself in a ship of some sort looking back on Earth from such a great distance and I get a feeling I just can't explain. Maybe extreme awe and loneliness? That we are an inconsiquential spec of dust in the vastness of the Universe? I believe that we really need to increase the amount of research for space travel. If we keep increasing the survival rate of the human species we are going to have one crowded world. Don't want to have to eat Soylent Green you know.
