How Equestria will End

Nah, this wouldn't work. After all, the Sonic Rainboom episode definitely proved that Equestria's sun is a relatively small ball of fire, MUCH smaller than the planet itself.
mlp.wikia.com/wiki/File:Rarity…

If Equestria's sun was really a huge star, it would be impossible for Rarity to fly so close to the sun that her wings would burn, let alone cast colorful lights in a wide CONE.
If the sun was a distant star, it would cast almost perfectly PARALLEL light rays, yet we see her wings are casting a cone of light, and geometrically, the sun would be at the apex of that cone... which in that scene would be at most a dozen meters away from Rarity. The fact that at that distance she's not obliterated by the sun, but just heated enough to burn the wings and cause a little sweat, suggests that the sun isn't extremely hot like a real star. The sun's diameter can also be estimated here, although the results seem somewhat inconsistent.

Either way, the conclusions are:
- MAGIC
- FRIENDSHIP
- ...
- Good story, Pinkie.

Pinkie! Don't spoil things for the kiddies.

lol

Wait, what?! XD

Sounds legit xD

Worse way to go I guess. 

Pinkie Pie does make a logical point.

 

Well...at least it'd be quick...

I suppose it wouldn't matter afterwards because Equestria would still end up crispy-fried regardless, but I wonder if that sudden jerk would be enough to destabilize it's sun, too...end results still basically the same, but...

Well, on the bright side the entire universe will be able to smell all that deliciously cooked horse meat :3

Haha, nice

OMG, poor Sweetie Belle!

Wow! An' AJ always told me that Equestria was gonna end in ICE. Like in a ice age, or somethin'...

Looks like I won't get to fly on my own after all. *sighs*

I... I don't wanna die!  

And that's how Equestria will end. Not in a bang but in a wimper.

 And that's how Equestria will end.
 PINKIE!!! 
 MY ENTIRELY MADE UP STORY IS COMING TRUE!!!
 AAAAAAAAAAHHHHHHHHHHHH!!!!!!!!!!!!!!!!! 

Think about it, a small mistake that brings the sun closer - even just relatively little - and you're all toast. And this can happen every day.
