There's plenty of real estate for extraterrestrial life, right?
Well, maybe not. An article recently published in the journal Physical Review Letters argues that much of the universe could be off-limits to complex biology.
The reason isn't a lack of worlds. Scientists analyzing data from the Kepler spacecraft bumped the tally of exoplanets to 1,000 this week, with thousands more awaiting accreditation. Most of them will get it.

Even if 90% of all space, for various reasons, is hostile to life's development that still leaves plenty of room for living creatures to thrive.
My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.
