It Is Possible To Travel Back In Time. Just Add A Spinning Black Hole

Even astrophysicists use hacks to do the impossible

Those of us who see articles with such titles love the biggest questions of all: where did we all come from, where are we going, and what is life, the universe, and everything? It’s as if we’re all infected with both sides of Fritz Leiber’s Curse of the Stars and the Smalls (required reading for fans of 1980s swords-and-sorcery).

So when a well-respected astrophysicist claims that yes, we can go back in time, we say, “wait, what?”

Two podcasts I follow are Astronomy Cast, hosted by Fraser Cain and Pamela Gay, and Universe Today, hosted by Fraser Cain. Both podcasts are humbling for listeners, and wonderful for reminding those of us who think we’re scientifically literate of just how ignorant we really are. I most highly recommend both podcasts for anyone interested in what lay beyond our planet’s atmosphere.

So yesterday, I was listening to Universe Today, episode 744, Fraser Cain’s interview with Ronald Mallet, a theoretical physicist and professor emeritus at the University of Connecticut. Fraser introduces Prof. Mallet as a “very well-respected thinker in general relativity, physics, astrophysics, [and] cosmology.”
