## Resource

Can microbes travel through space on meteorites? It’s an idea called “lithopanspermia,” and to work out if it’s even feasible, some researchers decided to shoot microbes — with a gun. Guests: K.T. Ramesh, professor of science and engineering at Johns Hopkins University; Lily Zhao, mechanical engineer at Johns Hopkins University For show transcripts, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠vox.com/unxtranscripts⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠For more, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠vox.com/unexplainable⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ And please email us! ⁠⁠⁠⁠⁠unexplainable@vox.com⁠⁠⁠⁠⁠ We read every email.
