Children of the Red King #2

Charlie Bone and the Time Twister


In 1916, young Henry Yewbeam’s lily-livered cousin tricks him into staring at the Time Twister marble, sending Henry ninety years into the future, where the cousin is still alive at over a hundred years and just as lily-livered as ever. The other children of time, some of whom are endowed with magic powers from an ancestor, are neatly divided into nice kids and horrid kids. There is never a doubt about which is which, although there are plenty of doubts about whether a rational model of time travel underlies the two (or possibly three) time travel instances. Please see the book’s tags for a short discussion of the issues. —Michael Main
“People can’t go back. You can’t change history Think about it! When my father was five years old, he lost his brother. It changed his life. He became an only child, grew up as an only child. All his memories are of being an only one. You can’t change that now, can you?”

“No,” Charlie said quickly. “I’m sorry.”

His uncle hadn’t finished. “Henry’s parents mourned him, just as they mourned poor little Daphne. James was their only child and, as a result, he was probably spoiled. His father died in the war and his mother left everything to him, including her lovely cottage by the sea. You can’t change that, can you?”

The Umbrella Academy, Season 1

  • by multiple writers and directors
  • 10 episodes (Netflix, USA, 15 February 2019)

Of the 43 children born 1 October 1989 with no gestation period, the eccentric and sometimes cruel billionaire Reginald Hargreeves brought up seven of them and turned them into the super-powered group called the Umbrella Academy when they developed powers. Nearly thirty years later, after Hargreeves dies, the five surviving members of the group gather at their family home. Oh, and: Number Six died some time ago and only Number Four can see him; Number Five disappeared about seventeen years ago, but he’s back (and in his 13-year-old body) after living 45 years in a post-apocalyptic future that’s scheduled to start in eight days. —Michael Main
As far as I could tell, I was the last person left alive. I never figured out what killed the human race. I did find something else: the date it happens. . . . The world ends in eight days, and I have no idea how to stop it.

Mindscape #124

How Time Travel Could and Should Work

  • by Sean Carroll
  • from Mindscape 124 [podcast], 23 November 2020

Alas, Sean Carroll doesn’t pull any punches in his realistic assessment of the kinds of time travel that are or may be possible under the laws of physics as we know them in our universe. Or, as Professor Carroll himself puts it: “. . . podcasting isn’t for the squeamish.” In my layman’s understand of his most excellent explication, time travel aficionados have two physical phenomena on which to hang their Hat Things:
  1. Time Dilation: Under the laws of Einstein’s special relativity, a fast traveler who leaves the Earth, zooming around for a while at near light speed before returning, will experience less passage of time than those who stay in the more-or-less fixed reference frame of Earth. How cool is that? Yes, you can travel as far into the future as you like, so long as you have a means of zooming up to a high enough speed and returning. (And according to general relativity, time dilation also occurs inside a high gravitational field, although I didn’t notice a discussion of this sort of time dilation in the podcast.)
  2. Closed Timelike Curves: The second hope for time travelers are certain distributions of matter that (according to Einstein’s equations of general relativity) result in directed paths through spacetime in which a traveler along the path is always moving forward through time—and yet completing a full circuit of the path returns the traveler to the starting point in both space and time. That’s the good news. The bad news is that such paths, called closed timelike curves, might only be possible in the presense of infinitely long rotating cylinders or other physical conditions that may be impossible to engineer.
Up in the ITTDB Citadel, many of us found ourselves in a disquieted state at this point in Professor Carroll’s podcast (roughly the two-hour mark). Some went to bed early in a kind of daze; others decided it was time for a long walk through the lonely ice paths that surround the Citdel. But for those with the fortitude to keep their ears glued to the pod, there was a great reward. Carroll had already waded through the swift, waist-high currents of causality, predeterminism, free will, the A Theory of Time, the B Theory of time, and more. But now he was ready to dive into deep, uncharted waters. Yes, now he was ready to leave known physics behind, to talk about branching time that went beyond the Everettian Many Worlds of Schrödinger’s equation, and to consider what kind of a world would be needed to allow stories such as Back to the Future and Looper to consistently hold together. With this in mind, he devices a four-pronged theory that concludes with what he calls Narrative Time. For me, narrative time shares some features with the time model of Asimov’s The End of Eternity (a model that we call Hypertime in our story-tagging system), but it goes far beyond that.

Suffice it to say that when all the Librarians up in the Citadel woke from their sleeps and returned from their treks, we had a celebration that was strident enough to raise Lazurus Long himself from the dead (if he is dead, that is). —Michael Main
I think that if we really try hard, we can make sense of this. But there’s a rule in physics or whatever that the more surprising and weird the phenomenon is, the more you’re gonna have to work to introduce some weird elements into your theory to explain it. That’s not surprising, right? So we’re gonna need some leaps of faith here, but I think I can come up with the scheme that involves four ingredients on the basis of which we can actually make sense of Back to the Future, Looper, and other similar movies.

Loki, Season 1


Hang on to your Tesseracts! Apparently, in Endgame, when the Avengers traveled back in time to swipe various things from the 2012 Avengers, they inadvertantly started a branch in time where Loki ended up with the Tesseract. Of course, once that occurred, the Time Variance Authority spotted him as a Variant and quickly recruited him to help in their fight against even more variant Variants. —Michael Main
Appears to be a standard sequence violation. Branches growing at a stable rate and slope. Variant identified.
