Spike can shoot nukes as a baby? What can he do as an adult?

@burnart  
Doc Brown said gigawatts, he was just used a variant pronunciation that didn’t catch on.
 
He pronounced it like the g in giraffe instead of the one in giggle.
 
But anyway… Favorited for that last line.

Also, the cloud might have been coated in ice.
 
Finally, magic, don’t gotta explain – after all, pegasi can move a cloud that size easily, but had great difficulty even slowing this one down. Did it suddenly gain mass when frozen? Maybe (M, IdGES), but mass it gained could just as easily be mass suddenly lost when in contact with opposing magic – such as dragonfire.
 
Another option: the ice that the ice arrows create is somehow contingent, fragile in contact with reality. After all, the energy Spike would have had to output to melt the thing would have had to have been exceeded by the energy needed to freeze the thing!

Thats what you get when you spend 3 years of your life at /b/

Allonso’s Hypotheses of animated television:  

Can we just cut to the chase and say Spike has Godzilla-level fire breath?

@SocDev  
You’ll want to fix that speech impediment real fast.

@SocDev
 
YOU FUCKING RACIST

Am i the only one who read niggawats instead of gigawatts?

@burnart  
whoops hit enter before I was done.
 
anyway spike likely provided more J of energy than the picture calculated, no you could not have melted 416 m^3 with a lighter in 4 seconds.
 
OP is still wrong about time travel though, because as draco said, its jigawatts not giga watts for the flux capacitor to work

@Mayojar77  
um, no, the iceberg would not have melted from any amount of heat, the melting process absorbs the heat. the amount of heat required to melt the whole thing would be a minimum of the mass of the ice times the heat of fusion. If some of it is flash steamed then that would also be the specific heat of water times the difference between freezing and boiling points, times the heat of vaporization. And I guess melting the ice would also require the specific heat of ice from its tempeture to the freezing point if the ice would colder thant he freezing point in the first place. And while atmosphericx temperature well be transferring an amount of heat to the ice, so spike wouldn’t need to supply all of the energy, he would have to have supplied the vast majority of it, assuming 100% transfer efficiency. And honestly the amount of heat of the flames lost to the atmosphere is likely greater than the amount of heat transferred from the atmosphere to the ice. TLDR, spike likely provided MORE energy than

@Bardic_Knowledge  
Also we do know that Neon Lights is an alicorn.

Actually, time travel requires 1.2 Jigawatts, not 1.2 Gigawatts.
 
It’s odd to measure the energy required in watts (joules per second) rather than joules since, as everyone knows, accidental lightning strike is the most common cause of time travel, and that only lasts a fraction of a second.
 
It’s quite likely then that Spike exceeds the requirements by a far bigger margin.

Whatever comes out of Tartarus next week doesn’t stand a chance against the Noisy Cricket.

Real world science is irrelevant in a universe with completely different laws of physics.

@archestereo  
Your comment wasn’t there while I was typing out mine. Still, it shows that we’re not the only ones thinking of it.
 
@Mayojar77  
We do know there are crystal pegasi. There was one in Three’s a crowd. I think we named him Amethyst or something.

@JP
 
…wow, in that case it’s almost as if all of equestria’s problems are the mane 6’s fault, lol

@archestereo  
True. But we don’t know if the ponies have always been so lax when it comes to security, or if it’s just a recent development. Perhaps the 1000-year peace lulled them to think nothing can go wrong?

@JP
 
“and possibly before that”
 
…possibly one of the most exploitable phrases ever spoken…

@archestereo  
The ponies’ lack of any safety measures and contingency plans has been going on since season 1 and possibly before that.

@Mayojar77
 
But they still could have had a team of pegasi keep the skies clear

@Bardic_Knowledge  
I don’t think there’s such a thing as crystal Pegasi.

@Bardic_Knowledge
 
…I just asked that…

@Mayojar77  
Not to mention if his fire breath was enough to flash steam even a little bit of it, then the extreme heat of that steam would cause a bit of a chain reaction that would let the rest of it melt easier.
 
As to the time travel quip at the bottom there, he wouldn’t be able to because the flux capacitor (which makes time travel possible) hasn’t been invented in Equestria yet.
 
And, as a personal observation/aside, considering the importance of the Equestria Games, why didn’t they have one of the crystal Pegasi clear the skies like Dash had to for the Summer Sun Celebration just over a year ago?
