Do you ever wonder what if the Doctor exists, and walks among us? That ‘Torchwood’ is real and the television show ‘Doctor Who’ is just an elaborate cover up ? If the answer to that is yes, ever wonder who he might be?

Well, in the grand tradition of me not wanting to discern between fact and fiction, let me tell you exactly who I think the Doctor is. Last month I told you who I thought the First Doctor was in real life. This month:

The Second Doctor: Carl Sagan

If the dark hair and eyebrows don’t convince you, let’s just take a look at Sagan’s far more than illustrious career. He is one of the first popularizers of science, a substantial supporter of the SETI program (and why wouldn’t he be? extraterrestrials totally exist), and he is both a trained biologist as well as an astronomer. He was about as renaissance as you can get for a scientist in the 1960’s, and since the Doctor knows everything about everything, I can only assume that Carl Sagan is one of his regenerations.

In addition to that, on Sagan’s posthumous award from the National Science Foundation, it was said that his “gifts to mankind were infinite” and that is something I believe at the very bottom of both my emotional and scientific heart. Couple that with how many times the Doctor has saved us (well, according to the show), and I’d say that his gifts are infinite as well. The obvious conclusion must be drawn: Carl Sagan is the Doctor.

But even if that doesn’t convince you, just watch the first few minuets of ‘Cosmos’. There, he invites you on a journey into space.

Isn’t that awesome? All of us who want to be companions already are, and we can ride the spaceship of the imagination, which I imagine is really just a pretense for the TARDIS. On a more serious note, though, listen to his voice. As long as he talks in that soothingly low, manly tones, I think I could face all the Daleks and the Cybermen in the universe.

For those of you who have Netflix streaming, ‘Cosmos’ is available to you so you can take a journey on the ship of the imagination, which really is about as close as we will ever really get to traveling through space and time with the Doctor.

So, show off your time traveling abilities. Who do you think will be the Third Doctor?
