why is no-one discussing the even more pressing question — what is the nature of the swapped "bloodlines"?

It looks to me like grandkiddy will be rapidly accelerated, possibly into adulthood, as a substitute for Peter to operate The Nasty Destruction Machine Thingee.

"Silence are cool" ...?

Of course. But, sadly, Jack's haikus were never published.

yes, very odd. but as a press release, it is meant for the US media who cover TV, thus highlighting US talent.

would love to have had Douglas Adams' take on this.

How many of those billion Earth-like planets have io9.com? Huh?

Yes. we've finally discovered what The Event was... it was the writer's strike, and the human race has never fully recovered its ability to write.

and, it might not involve combat at all —- it could simply involve lack of immunity to diseases brought by the new population(s) — in either direction.

that seems like an over-reach. although the sheet might be stretchable, that does not also mean that it will be impervious to breaks from high momentum solid objects. it's about the strength of the molecular bonds, i suppose.

Yes, i fear my understanding of the nature of time is completely inadequate.

Since space and time are connected, I wonder whether the inflation of space was paralleled with inflation of time. I am not sure what that would mean, exactly, but i think it's a valid question.

not to mention, what if Jeff Greenfield hadn't ever become famous through his appearances on William F. Buckley's Firing Line... this book wouldn't have been written, nor any of these posts on io9. scary.

absolutely awesome.

what if Khan had defeated Kirk...

actually, what hooked me—i was really ready to let it go-was the discovery of the Hominid skull in episode 4. and i really like the actors playing Tate and Cas.

that's because i am a total sucker for schlock?

Sorry, CJA — you are as smart and insightful as they come, but this episode was a near total yawn. When we first met Jocee, it was clear that she had something of the Helen Cutter weirdness about her (beyond her shock). And you really didn't know, at the very instant that the real Jocee was left, that she'd be seen…

Vegas odds against the existence of Dark Matter just skyrocketed.
