I am merely posting it here as well as giving some minor prefacing context where able to.

MASSIVE SPOILER WARNING FOR PROJECT HORIZONS.

Preface[]

Project Horizons is a moon based weapon that fires meteorites on a precalculated trajectory. We know from Cognitum that the mass of the metorites is several hundred tonnes. Using Earth as a fill in guesstimate for other important factors such as size, time frame, location, and gravity this is what was concluded. I have also taken the liberty of sourcing the chapters where said quotes originate.

The Original Calculation Post[]

--MAJOR SPOILERS AHEAD--

Distance from Earth to Moon: 385,000km

Distance from Earth to Sun: 149,597,870km

Circumference of Earth: 40,008km

Circumference of Moon: 10,916km

Circumference of Sun: 4,366,813km

Total distance (canon): "A dotted line rose out of the palace, then started to curve. It looped around the planet, then around the sun, then back around the planet, back to the moon, and finally down right on Hoofington." -Goldenblood's Interrogation Software (Chapter 67)

3x Earth-Moon separation

2x Earth-Sun separation

1x Sun circumference

2x Earth circumference

1x Moon circumference

Total distance: 304,808,485km.

Timeframe: "Horizons will fire tomorrow afternoon and impact at midnight." -Goldenblood (Chapter 70)

Setting "Afternoon" as 3 PM and "Midnight" as 12AM, time from firing to impact is 9 hours.

Mass of Tom: "Goldenblood commandeered Horse’s mechasprites and sent them to the moon on a clandestine rocket to build a facility and to collect and fuse moonstone into a projectile massing several hundred thousand tonnes." -Cognitum (Chapter 65)

I will set the mass at 250,000,000kg, or 250 thousand metric tons, for simplicity. Tom could very well be larger, but not smaller.

Velocity is measured in meters/second, so we need to convert.

304,808,458 times 1000 is 304,808,458,000 meters

9 hours is 32400 seconds

304,808,458,000 divided by 32400 is 9,407,669 m/s

Kinetic energy is 1/2 mass times velocity squared.

So 0.5 times 9,407,669 times 250,000,000kg squared

0.5*9,407,669*(250,000,000)^2=2.939*10^23J

Also known as:

293,900,000,000,000,000,000,000 Joules.

Now we need to calculate Megatonnage and total atmospheric temperature change.

The temperature for temperature change in a body is q=McT, where M is the mass of the atmosphere (5.3*10^18 kg), c is the Specific heat Capacity of Air (1.005 kJ/kg), and T is the change in temperature Kelvin.

We seek the total temperature change T, so the equation is now q/Mc=T

We must convert Joules to Kilojoules, so 2.939*10^23J becomes 2.939*10^20kJ

2.939*10^20kJ/(5.3*10^18 kg*1.005kJ/kg)=55.176K change in temperature

The average world atmosphere temperature would become (starting at room temperature):

348K

78C

202F

Now, for Megatonnage.

1 Ton of TNT is 1.184 Gigajoules, or 1.184*10^9 Joules of energy

Dividing 2.939*10^23J by 1.184*10^9 gives 2.482*10^14 tons of TNT

248,200,000,000 Kilotons

248,200,000 Megatons

248,200 Gigatons

248.2 Teratons

For comparison, Tom is the power of 2,482,263.514 Tsar Bombas (100MT), and 2.555 Chicxulub meteors (97.118 Teratons).


This would eradicate all life on Equus, easily, even if it didn't hit the Tokomare. Sheer velocity alone makes this thing INCREDIBLY powerful.


What scales to to this AP wise?[]

Plugging 248.2 Teratons into our tiering system this would give High 6-B to the following:

  • The Eater of Souls (No Profile yet) (From catching this thing, Had also fed off a direct strike from Celestia Prime prior.)
  • A minimum for Trottenheimers Folly's AP It was specifically designed to destroy this thing before it made impact. Pythia, who can see the future, claimed it would vaporize it's mass. (Chapter 77} (Blackjack, and Cognitum)

It would also[]

  • Probably further prove that the Rainboom Calculations for FiM would be massive outliers if used. At least for any Project Horizons related page.


What scales to this Speed wise?[]

Seeing as The Eater of Souls had to catch and thus react to this projectile we should also take into account the speed of which it was traveling, 9,407,669 m/s (Sub Relativistic). Despite knowing where it was going, catching this projectile would justifiably put it dozens of times higher than the verses many Bullet Timers. Following this scaling chain/line of logic, the following characters with profiles would scale to this:

  • Blackjack (Alicorn Form): Obvious, Ended up killing The Eater, and was capable of dodging its Anti Air arrays after reaching low orbit on her return trip from the moon, as well as in ground combat.
  • Legate (Post Resurrection): Blitzed Alicorn Blackjack twice and nearly killed her.


What scales to this Lifting Strength wise? (Updated 10/19/21)[]

Quote from Chapter 77[]

Tom impacted, and I had a front row seat.

The tapered crystal seemed to have grown in its transit, or perhaps I was just a lousy judge of size. The tip of the stone dragged along the edge of the shaft in a blinding trail of fiery light and magic that swirled around me. Only my proximity to the shield talisman kept me from being instantly crushed and blasted off by the hurricane force of displaced air or the colossal heat. I’d eliminated five of the shields, but the sixth still sufficed to keep Tom from reaching the Eater.

An enormous flaming blue alicorn seemed to swell from the stone, and brilliant, blazing hooves struck around to either side of the magical wedge holding it at bay. The Eater wove back and forth, laughing with wild abandon. Those floating claws snatched handfuls of blazing spirit fire and drew them to the nucleus, which expanded into a strange, ever shifting geometry that absorbed the energy and grew organically into ever more complex shapes.

YOUR CHAMPION HAS FAILED, the Eater taunted amid mouthfuls of glowing blue luminescence.

WITH MY LAST MOMENTS, I WILL DEFY YOU! Tom cried out as the Eater’s disembodied hands ripped away more flaming gobbits.

YOUR LAST MOMENTS ARE DELICIOUS, the Eater cackled as he feasted on the still-living star.

And all I could do was hang there, my guts dangling out beneath me, my chest ripped open. I’d failed... I’d failed... Sister... Glory... I’d failed...

I closed my eyes. At least I could enjoy the moonstone’s song, beautiful, but now desperate and strained as it fought against its nemesis. It truly was a beautiful melody...

But not the only song I heard.

I opened my eyes and looked down at my chest. I guessed it was the big round drum with all the wires coming out of it. Slowly, dripping blood and other fluids, I pulled it from my crippled chest cavity. One of the fingers on the hand curled around, pinning me at my severed torso.

You have a heart of moonstone. That was what Glory had said. I stared a second longer, and then I lifted my sword in my other hand. Carefully, I cut the end off the drum.

There, nestled in a bed of gemstones, was a hunk of moonstone. I’d been told she’d been lucky to find an ‘appropriate gem’ to power my body, and as I stared at it, I realized that I’d seen it before: in Horizon Labs and the disassembled silver bullet. It was larger than the slivers in the slugs I’d used before. It hadn’t been corrupted yet.

I wasn’t beaten yet...

I yanked the stone free, and instantly my vision filled with “CRITICAL ERROR” in bright red letters and “SWITCHING TO RESERVE POWER” with a percentage that was ticking down. Rapidly. I stretched myself out along the frame, feeling my life ebb away with each exertion. Then I took the stone and pressed it against the casing. The metal began to glow brighter and brighter, and then exploded with a detonation that blew my hand apart but left a hole in the metal. I fumbled with the stone, barely able to catch it with my other hand, holding it as if my soul depended on it. I raised the sword with my magic.

NO! the Eater screamed, grabbing me again and pulling me away from the platform. The moonstone did nothing against the fleshy meat protecting his starmetal skeleton. NO MORE INTERFERENCE. YOU ARE DONE!

Almost...

But I wasn’t quite done.

I slipped into S.A.T.S.

Three magic bullets to the F.A.D.E. diamond inside the case.

Execute.

The magic bolts streaked out, hitting the insides of the box and ripping out the connections between the diamond and the power supply. The gemstone went dark, but the field was already active. The Eater froze, and then its aura flared wildly as it emitted a hysterical laugh of triumph. FOOLS! FOOLS! FALSE FOOLS AND FOLLY! SURRENDER TO DESPAIR!

No. I refused. Every second of life I had left would be opposing this thing. For my friends who had fallen, and for those who still survived. For Glory. For P-21. For my Sister. I stared at the stone and then closed my eyes. I might be broken. I might be dying. I might be in agony. I was used to it. And while I couldn’t raise or lower the whole moon...

I could raise a small piece of it.

My horn flared as I pushed Tom up the shaft. Just a bit. Just enough for the wedge of magic to lose power, flicker, and disappear. With a relieved smile, I cut the magic.

Tom fell.

The Eater dropped me as Tom smashed the platform to the ground, and I fell along with it. Both of us landed on a knoll of rock, broken and bent. Lying on my back, I watched as the Eater clawed and raked his hands and blades against the moonstone, but now nothing protected him. Every impact of Tom’s hooves was a lightning bolt, and bit by bit, Tom smashed the Eater down towards the earth, and me.

Context[]

Tom is caught by The last FADE Shield and is slowly being absorbed from a distance by the Eater and converted into Star Metal. Blackjack laid to the side, critically wounded from being torn in half and having her wings torn off, she is exhausted from hours of fighting the Legate, Spawn created from the Core, and The Eater itself. In a last ditch attempt to shut down the shield Blackjack rips out her own heart and uses it to trigger a chain reaction to destroy the last remaining shield. Though the shield had been destroyed. Tom is still being absorbed by The Eater due his essence powering the absorption process, if the isn't stopped The Eater will fully resurrect and destroy all life. Using nothing but reserve power in a critically injured form, Blackjack lifts Tom away from the generators causing them to stop the power transferal process before letting him drop right on top of The Eater, triggering one last Star Metal Moonstone chain reaction that kills everyone.

Toms' Original Moonstone Mass[]

Let's Quote the original calculation we've used to determine Tom's approximate weight:

Mass of Tom: "Goldenblood commandeered Horse’s mechasprites and sent them to the moon on a clandestine rocket to build a facility and to collect and fuse moonstone into a projectile massing several hundred thousand tonnes." -Cognitum (Chapter 65)

I will set the mass at 250,000,000kg, or 250 thousand metric tons, for simplicity. Tom could very well be larger, but not smaller.''

Other Factors to consider[]

  • Tom was clearly not at full launch mass however he was still able to outweigh and over power The Eater despite the loss in mass.
  • Blackjack, the main party involved in this lifting feat, was on deaths door. Again having just been torn in half, having her wings dethatched and even having ripped her own power source heart out. She quite literally performs this lifting feat on reserve power.

A decent enough lowball for this lifting feat[]

We know Tom was still at a capacity to destroy The Eater or at least overpower him using his mass so an absolute lowball of being at half should be useable for this calculation. That leaves us with Blackjack having lifted at the absolute minimum 125,000,000 kilograms.

That would give Blackjack Class M Lifting Strength for Telekinesis, despite being only one letter grade higher, it's still far greater than anything Littlepip has done at it's absolute minimum.
