Everything we know about the universe and all the laws of physics, apply to four percent of the universe. The other 96 percent are the unknown phenomena of dark matter and dark energy. “If we account for all the matter and energy that we’re familiar with,” says Neil deGrasse Tyson, “and measure up how much gravity it should have, it’s one-sixth of the gravity that’s actually operating on the universe. We call that dark matter. It really should be called dark gravity. and we don’t know what that is.”

“The human imagination is a preview of coming attractions,” Albert Einstein was fond of saying. Viruses are essentially roving segments of genetic material that have learned how to “put on space suits and leave the cell,” observed Greg Bear in his epic work of science fiction, Darwin’s Radio, that mirrors Einstein’s adage, suggesting that viruses in our genome function as carriers of evolutionary messages—a genetic radio, so to speak. In this sense, we may simply be spaceships for virus.
