In the short article "What are the odds of Earth's cataclysmic end?" IfA researchers explain some of the possibilities other than a galactic highway. Don't Panic -- you don't need to lose any sleep over them.
One of the things I love about astronomers is their ability to talk about their science in plain language. You can hear for yourself at the free "The Hitchhiker's Guide to the End of Everything", a panel discussion by University of Hawai'i astronomers, at 7 p.m. Wednesday, May 4, at the Art building auditorium on the Manoa campus.
Another thing I love about science in general is that truth is almost always stranger than fiction ever could be.
