'You' are Rainbow Dash.

You and the girls are all in stasis, headed to Cepheus Prime for some routine diplomatic talks.

...So why did everything just go dark?

Written for Zaponator's "Aliens!" Fic Contest Thingy of Great Justice.
Thanks to Fourths for pre-reading.

Space can be lonely and cold, but during the long voyage to her people’s new home, Twilight finds the time to talk with her friends about what their new world will be like.

A Homeworld crossover. Written and edited in 9 hours as a speed writing exercise.

Dust has lived on the edge of Ponyville all her life, keeping to herself and studying. She knows Princess Twilight, and so when she realizes she's made a big discovery, she's eager to run to the castle and tell everypony the good news. But when she goes into Ponyville, they don't seem very happy to see her.

Why would that be? She didn't do anything wrong.

After being marooned on an icy world in unexplored space, Lumina must now face the perils of this frozen wasteland and search for some way home. But in this dark place, she discovers something that was lost to pony kind ever since the fabled Equestria sank into the ocean over 10,000 years ago. Something that will change her, and possibly the entire galaxy, forever.

Not a cross over, and not an alternate universe. This is the far future, and this has happened before.

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

What would you do if you've gone where no mare has gone before, and have no idea how to get back?

Rainbow Dash found herself alone in a strange, magicless world governed by entirely different natural laws than Equestria, ruled by a race who thought themselves the only sentient species in the universe...

SG-1 is sent through the Stargate as a forward scouting team for an extended scientific mission to P3X-597. Arriving in a long abandoned castle, the team heads out for the nearest village. As they approach, it becomes clear that the locals aren't exactly human. Their contact with the pony-like aliens goes well, conveniently timed alongside a celebration of the sun, until an over-the-top, hammy, evil pony appears to ruin the festivities.

A Stargate SG-1 crossover.

It was a night like any other in Ponyville. It was, until a shooting star turned into a burning streak that roared overhead before crashing off into the distance. At first it looked like a meteor. But then it had turned, quite sharply, and flattened its trajectory, sailing uncomfortably close to the treetops.

Twilight Sparkle had dismissed the idea of visitors from beyond the stars as pure fantasy, the type of pulp novel that Rainbow Dash seemed to enjoy. Now it was a frightening possibility, and now nothing could ever be the same.

Unbeknownst to her, the accidental visitors to Equestria are just as frightened. Laws of physics that had long been understood and mastered have broken down, leaving them trapped and sitting on a possible ticking time bomb on this strange fantasia of an alien world. As utopias collide, both are faced with an event outside all comprehension, events which civilizations rarely encounter more than once, and generally the same way as a sentence encounters a full stop.

A crossover with The Culture series by the late Iain M. Banks.

First contact. Not just with a new world, but with a world in a whole new universe. Initial negotiations go well, so Princess Celestia makes a visit to this 'Earth' to cement peaceful relations. Unfortunately, even when you are as experienced as the goddess of the sun, it's the little things that can trip you up.
