Experiment shows theory describing formation of interstellar benzene does not actually produce benzene
Astrophysicists at the University of Colorado's JILA, National Institute of Science and Technology, have conducted an experiment to produce benzene the way theories have predicted it is produced in interstellar space and ...
One day we might seed the universe with life. But should we?
Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will explode and irradiate all life, a black hole will engulf the Earth, a Mars-sized interstellar asteroid ...
