“In very, very broad terms, it’s something like this: We live in a universe in constant expansion, atoms are easily excitable and movement is easy to accomplish by applying certain amount of force to an object, and that means there’s always an acceleration present.”
That’s reasonable. With the fact that magnetic and gravitational waves are virtually everywhere you go I’d say it might be impossible to not be accelerating some amount.
“Consider the opposite in which, instead of constant movement (this is pretty complex stuff) , everything is slowing down. What would you think would happen if the Universe just stops moving alltogether?”
Well if that happened then nothing would happen following that. Though on a quantum scale I don’t believe that’s even possible. (depending on what you’re calling “moving”) However I still don’t see what this has to do with changing the speed of light.

@Mayojar77
So we’ve been taught, that’s why it’s a currently studied topic, because they’re not sure. (and how could they be, since we don’t live in every part of the universe or at every time in the universe to test it)
@QuasarNova
I must just be really dense or something because I just don’t see the relation.
The example was meant to further in your comment: “I figure if you slow down the speed of light it could throw things off, but I just don’t see how speeding it up would do much, but I really don’t know, though I kind of want to find out.”
Just take the Earth as a minor example of what would happen if suddenly the planet slowed down it’s rotation.
As for the second statement, SpoLi in the void, it’s a constant (supposedly)
@QuasarNova
I’m confused at where that came from and its relevance…
Looking at some of the effects of changing the speed of light WITHOUT changing anything else, and large changes would be disastrous. However small changes should be fine. (and a current topic of research is whether the speed of light is even constant in our universe)
Just take this as an example. You stop the rotation of this planet… Discord would beg you to spin it again.
Accelerating is sometimes not the problem becuase according to some theories, the faster something goes, the slower the rest of the Universe gets. The problem is always slowing down.
@Draco_2k
I don’t know what the effects would be, and frankly I doubt you do either, unless you’re a very serious physicist. I figure if you slow down the speed of light it could throw things off, but I just don’t see how speeding it up would do much, but I really don’t know, though I kind of want to find out.
I like QuasarNova’s idea, kind of bypasses this problem.
@Techy Pony
Well, yeah. But if you accept things for what they are without figuring out why they’re the way they are - that’s boring.
My guess, the differences in light-scale, so to speak, would completely destroy chemical and atomic bonds as we know them to begin with. Though that’s just my intuition. I dunno.
Maybe ponies are wave-based lifeforms void of ordinary matter?
What if Celestia contracted the distance between the Moon and NM by applying the Alcubierre Principle? Instead of traveling faster than light, the space between NM and the satellite was reduced contracting the space liek a rubber band?
@Draco_2k
Actually, I’m not sure how much (if any) changing the speed of light (or making it instant) would effect macro scale physics. (aside from the obvious) Sure it would, but I don’t know if it would just throw everything out of wack.
@Draco_2k
Well that’s what I’m saying, maybe their physics are just completely different, and yet still lead to a universe that appears to function…similarly.
@Mayojar77
That’s not sensitivity, that’s ….(can’t think of a word)
Technically, maybe, perhaps we do see green with more sensitivity, thus giving us better distinction of different shades, but just because our eyes see it better doesn’t mean our brain doesn’t turn down the gain so to speak. Thus giving us more green color accuracy without it looking brighter under the same intensity.
Cross referencing the relative brightness of the sun’s wavelengths and the human eye color sensitivity, I don’t know why the sun doesn’t look green. Maybe it’s because of what I just said with our brain compensating or something?
Anyway….back to the original point. Without the effect of our atmosphere, the sun LOOKS white, not yellow.
@Techy Pony
Whoah, whoah. Speed of light isn’t just how fast light travels, it’s how fast anything that’s anything travels, including gravity and matter. An alternate speed of light would probably alter every single fundamental of the universe until it barely if at all resembles our own.
@Mayojar77
I can see exactly three two of green. What say you now?
@Mayojar77
Seeing more shades doesn’t mean you see them with as much intensity. Just like our ears have different sensitivities to different frequencies of sound. Place sound from 20Hz to 20kHz at the same dB level and it will not sound the same volume throughout.
@Draco_2k
So maybe light and magic travel at much higher velocities than our universe, or both are instant. Then your magic effects the distant object instantly and you see the effects instantly.
In “Princess Twilight Sparkle pt 1 & 2”, the time it took for NMM to be sent to the moon and for it to be seen was ~ 2.5 seconds. The Time it would take for light to make the round trip is 2.6 seconds. Given that Luna had to accelerate, at some point either her, or the light, was traveling faster than light in our universe. Thus I claim there are no such cosmic speed limits, that or it’s just much faster.
@Techy Pony
>wouldn’t it just be easier to put their planet into orbit and spin it and be done with it?
You might be onto something here. Maybe we should do this.
Hm, wait. If the magic operates faster than light, wouldn’t that make manipulation of objects at a distance impossible because of the massive lag between observer and the manipulated object? Like, you’d need to perform every single tiny motion eight minutes in advance of it actually having any effect where you currently are.
@Draco_2k
Well the reason for that is because it’s a kid’s show xD
I think it’d be much easier to just rotate the earth rather than move the sun. What I don’t understand is that Celestia “raises” the sun, wouldn’t it just be easier to put their planet into orbit and spin it and be done with it?
If they were literally moving the star every morning, depending on the acceleration you could calculate the force, but it would be a lot. As far as we know, them using magic draws energy from somewhere other than their own bodies, so maybe it’s feasible with magic? Though it’s not about force, neglecting gravity, any force would move the sun, it’s a matter of how fast you want to accelerate it.
Actually, if in some weird hypothetical you had a lever with the earth as a pivot and the sun as the target to move, given the speed of sound through steel, it’d take about 1 year for the force to reach the sun. (though it would’ve dissipated into heat early on, like a second or two)
I think magic operates faster than the speed of light, that or it’s a white dwarf sitting about moon distance away. (or light is faster in their universe, or physics are just entirely different, the most likely case)
@Techy Pony
…and reproduce without any visible genitalia.
In your professional opinion, what would be the force required to rotate a star half a revolution around a planet’s axis (then stop)? I’m guessing if you were using a lever to do that, it’d have to be so big it’d take a few decades for the physical motion to reach from one end of it to the next.
