[MLP:FiM-HiE] Arrow Mision Contact Logs

OTOH, cloud herding.

Cloud herding makes is wierd yes. Teleportation requires stupendous amounts of energy, or something stupidly exotic going on. It isn't shocking on the level a geocentrism solar system, but it's not that far behind.

A thing about the Geocentric Solar System being bluescreeningly shocking to the guy... Is you have to remember he's been on approach to this system for 22 weeks, and was informed of it even before then.

He's had over six months to be shocked. By the time he arrives in-system, its less about being shocked, and more about observing and documenting and finding out WHY.

The only reason he's here is because of how shocking a Geocentric Solar System is.

What???

Also, once they are able to speak to each other freely, are we ever going to see things from Twilight's point of view? Maybe a flashback sort of thing where she's remembering where she first met him?

Also, his logs must include the day he finally finds out 'why' the system is geocentric

Not only that, she holds the star together as to not be ripped apart and smeared across half the galactic arm by the titanic gargantuan insane inconceivable _________ tidal forces.

An Equestrian observer is probably not going to perceive much Doppler shifting (if any, it's a blue tint in the morning and a red tint in the evening), but from Earth the system will look like a police beacon.

Suspension of disbelief.

Great and Powerful Trixie.

Thanks.

On the space side of things, it's said that the planet itself only rotates once every 13 months or so right? Do you think that would have a large effect on their astronomy? I know that a lot of the stuff we have/do require pointing a telescope/radar dish at something consistantly for long periods of time. So having 6-7ish months where it's in the sky constantly (even if you can't really see it during the day) should be of some aid to that. But that would also limit them to just that 6 months without allowing it to continue longer (barring tech level and magic).

Also, seeing what is close at hand and extroplating that outward is how you build up to things, yet their system is the exception and not the rule... that has to screw up any predictions that they could make. Although, their tech/magic level might not be at the level where these things matter (I honestly don't know when they would notice these things or when the differences would start to matter)

Send it into EqD now and you'll get even more hits.

Saw it on FiMFic. I enjoyed it, but I have to say that seeing so many people pointing out spelling errors is more than a bit funny.

Is there a doppler shift from Equestrian POV since the star is on circular orbit?

Anyway, Celestia is awesome.

And I am shocked that nobody here has speculated on the possibility of using relativistic stars as weapons.

Doppler redshift and blueshift is visible to observers respectively behind and in front of the velocity vector at the given moment. So supposing you are roughly in the same plane as the orbit and the sun is going clockwise (looking from what you would think of as above in such an arrangement), then its blueshifted when on your right and redshifted when on your left.

Is it so even when the moving object is in circular one AU orbit and the observer is at the center of the circle? Since the way I visualize it, the observer is never actually front nor behind the sun's velocity vector. The vector is always at a 90 degree angle from the observer at any given point.

Or has it been too long since I've studied physics?

The original reference to Doppler shift was about it being visible from Earth, not Equestria.

No, you're right. If your position vector to the moving object is perpendicular to the velocity vector of the moving object, you do not observe a Doppler shift.

Yes, except you're not completely perpendicular. That would be in the planetary core of Equestria. But your typical observer would be on the surface, so at noon you're a few hundred kilometers closer to the sun than in the morning or evening. Whether this comes out to a perceivable Doppler shift I can't say without making the calculations.

On Earth you're approaching the sun with about the rotational speed of the Earth surface, and any Doppler shifts are swallowed by atmospherical effects. On Equestria we have to scale the solar translation velocity from 1 AU down to the planetary radius, angular velocity constant (since it's funcionally the same whether the sun orbits the planet or both stay in place and the planet rotates, so we can change the frame of reference and facilitate our calculations). If I'm not mistaken in my trigonometry. I'm too lazy to do the calculations now.

Anyway, that's one of the lesser problems.

EDIT: Stupid me, it's the same effect as on Earth, i.e. negligible. That velocity? One rotation every 24 hours.

Earth's rotational speed is about mach one. Any dopler shifts we may notice would only be on a spectrograph.

I think he was suggesting that Earth might be perpendicular to the plane of rotation of Equestria's sun, and thus would not see a red or blueshift.

No, he's right. My point is that any point on Equestria or Earth will be sufficiently close to perpendicular that it would not be observed. Even Earth's center is effectively never perpendicular because of its elliptical orbit.

This.

Be nice to see the ponies point of view too.

Just a comment on the actual story, but I am enjoying a HiE fic that actually involves language barriers.

Looking forward to seeing when those get breached, but considering that this is first contact with an entirely alien culture, well, plenty of delay is expected.

I also enjoyed how you've managed a lot of the non-verbal communication, which is rarely handled well.

How long till Applejack and Fluttershy show up?

...

I actually saw it on FImFiction first but the initial description put me off, good that I gave it a try anyway after finding it here.

That's the correct terminology.

*shrugs*

Sucks not to be a native english speaker then, still find it funny
