Howling:Jack is mortal

Any guesses a to how Miracle Day could have made Jack mortal? Jack is a fixed point in space and time, which means that normal alien technology couldn't have done it. Maybe the entire Human race is now fixed points in space and time and he somehow isn't anymore, though they seem to resemble Owen more than they resemble Jack. Maybe the rest of the Humans somehow absorbed his powers of immortality, though someone would obviously have to be responsible for it.Icecreamdif 02:54, July 9, 2011 (UTC)

I don't know that it's necessarily true that normal aliens (or even humans) can't ever change a fixed point; just that generally it's a hard thing to do and has disastrous consequences if you pull it off.

Also, just making Jack mortal might not count as changing a fixed point in time unless he actually dies. After all, making it so Adelaide Brooke didn't die on Mars turned out not to matter in the grand scheme of things so long as she died that day; in the same way, as long as Jack is alive and re-immortalized in a few months, it may not matter that he could have died during those months.

On the other hand, even if the Miracle gets resolved, unless it somehow gets unwound like the Year That Never War or something, it's hard to imagine that this wouldn't have a drastic effect on human history, to the point where it would affect our future expansion into the galaxy as much as, say, Adelaide Brooke surviving. So, how is that allowed? And how does the Doctor not notice such a massive rewrite to human history? (Yeah, I know he's busy a few millennia in the future, but it's future humans that he's busy with. Then again, I suppose it's possible that he does know something is up, e.g., the Earth Empire should have already won the Cyberwars or something, but he's got more important things on his mind than figuring out why that changed?) --99.8.228.116 09:59, July 16, 2011 (UTC)

How do we know that the Miracle wasn't always going to happen. Maybe by the time of the Great and Bountiful Human Empires, the Miracle is a major event in Earth history. Either way, whoever caused the Miracle is clearly trying to kill Jack, as evidenced by his poisoning, so it can't be a coincidence that he's mortal now. Icecreamdif 04:08, July 17, 2011 (UTC)
