Challenge #02665-G108: Temporal Theory vs Reality

In today's episode of "Fun with Wormholes!" we will discuss how most people's family lines are actually Mobius Strips! -- SilverRey

Today in Fun With Wormholes, we explain how it's theoretically possible to be your own descendant. It all begins with one simple graph... An X-Y axis graph where one axis is time and the other is distance. On it, a line is travelling away from zero at a slight incline relative to time.

Here is our hypothetical traveller, moving at close to light speeds through space. If they then enter a one way wormhole, they travel faster than light, over vast distances very rapidly. The travelling line moves very far along relative to the space axis, but backwards relative to time. This is usually why we say that time travel is possible, but functionally useless. You may have gone back to the time of the dinosaurs, but it would take you the rest of that time to get back.

People would think that returning through the wormhole may be advantageous to time travel, but not if you use the same wormhole. A different line traces a path forward in time but backwards in distance, once it enters the wormhole, it crashes into the original traveller. Of course, using a different one-way wormhole only puts you deeper in time and into an unknown portion of space. So. How do we become our own descendants?

Challenge #02197-F007: The Girl Who Circled Time

"My apologies for the security breach. I was experimenting with temporal rifts and found myself here." -- Anon Guest.

Roswell, New Mexico. 1947. Everyone has a story about what happened that year, but it was a weather balloon carrying a top-secret attempt at detecting enemy nukes and that was that. However, since the American Public believed there was a coverup, it and the nearby Area 51 became the perfect stalking horse for other, experimental technologies.

Then there's the actual Incident that happened

Challenge #01991-E167: Unobtrusive Observation

Time you can visit. all you can take is pictures, all you can leave is footprints. -- Anon Guest

There are rules to time travel. Some are invented on the fly, others make more sense than that. First and foremost is no excessive interaction. One cannot, for example, go back in time to tell Freddie Mercury or David Bowie how influential they become. Especially towards the start of their careers. One cannot also travel back in time and leave an iPhone in

Challenge #01990-E166: Mystery Analysis Department

Step back in Time. It smells different, the food is odd. But you are here to record History. Pick an Era.

the Past is a different country -- Anon Guest

The oddest thing about the early twentieth century had to be the colours. Followed closely by what people willingly put in their mouths. It was just... odd... to see any era before the nineteen fifties in any other tones but black and white.

The past is another country, indeed. The food is

Challenge #01862-E038: Trust Yourself

She left a message for her younger self to read. -- SongSpired

Time travel was a bitch. Sorting out the mistakes of life retroactively was never a fun thing. Making sure she would pay attention to her own warnings to herself had been the work of several journeys. And multiple encounters. She could not talk to herself. Both brains shut down for that sort of thing. Leaving notes, however, was perfect.

Her teenaged self was asleep in bed. Sleeping the sleep of

Challenge #01517-D056: A Strange Land

The past is another country. -- Knitnan

Pam walked around the corner into another world. At least, that was what she thought to begin with. The very air smelled different. Disgusting, in its own way. None of the buildings were familiar. And everyone was dressed really weird. And everyone was staring at her. Pam clung to her purse and tried to be discreet in digging out her self-defense stuff. It had, of course, settled to the very bottom of her bag.

She

Challenge #01395-C300: Don't Feed the Birds

Person 1: (Panicked and running) "There's a dinosaur in the time machine! THERE'S A DINOSAUR IN THE TIME MACHINE!"

Person 2: (Vaguely annoyed) "Again? Those sneaky bastards..." -- OohLookShiny

Callie looked vaguely alarmed as Baz dug into his mini-fridge and extracted a sausage.

"Don't worry," he said, "It's chicken." He casually strolled down to the temporal lab where a black-and-white feathered dinosaur waited and watched expectantly. As Baz entered, it burst into song.

"That... sounds like a magpie..."

"Probably one of their

Challenge #01270-C175: Magnificent Man Returns

The glory days when superhero du jour would nick into the nearest phone booth. It's all cell/mobiles today and most of them are smart phones. -- Knitnan

[AN: It was mostly Superman who did that, and now they just bullshit it away with changing so fast that nobody notices anything]

Nobody had seen Magnificent Man since the early eighties, when the Time Tripper had tricked him into consuming one of his Magic Mushroom Pies. Magnificent Man had vanished without a trace.
