1997966 What Mach speed does a bullet travel out of a KRISS Vector..? Girlthing... BTW...

[Seraph973]

Calculate the age rate of dragons as compared to ponies. Should be simple.

...Although it's not related to ponies, I can answer that question!
Depending on variables like barrel length, cartridge powder loading, bullet loading, etc.; the KRISS Vector's muzzle velocity can range from anywhere between 250–380 m/s (Mach 0.735–1.117), possibly lower or higher under special circumstances (such as using low or high pressure specialized hand loads). However, since KRISS recommends the use of relatively heavy low velocity 230 grain full metal jacket loads with their KRISS Vector series on their website (which is unsurprising: hollow point, soft point, and other "irregularly shaped" bullets tend to make sub-machine guns jam more often—and higher-pressure rounds can cause irregular behavior in the gas system, leading to mechanical failures), I'd narrow that range to 250–290 m/s (Mach 0.735–0.852).
Slightly odd question, or at least a question lacking context to lead up to it—can I inquire as to the reason why you asked that specific question?

Also, happy birthday. Or something.
Just accept the damn gift.

Calculate the age rate of dragons as compared to ponies. Should be simple.

Unless I've missed something (which is very possible, as I don't really watch the actual show) there hasn't been any actual clues to determine how quickly dragons reach maturity nor their average age of death. Or even how quickly ponies reach maturity or when they commonly die, for that matter.

However, we do know that dragons seem to grow rapidly when they experience prolonged periods of greedy behavior, so with that in mind my answer would have to be that dragons age however quickly that happens?

Also, merry Christmas.

—Probably definitely never?

...Look, I'm sorry. It just grew far beyond my ability to actually produce it. A lot of my projects seem to have the tendency to end up like that—like my "infamous" Fate/RETOLD Project, which was planned to consist of the story Fate/parallel circuit and its planned sequel Fate/heaven fractured, both of which combined would have been at least two magnitudes grander in scale than Without Regrets would ever have been! I just have the habit of building things up higher than I can manage.

I'm sorry I couldn't deliver what I promised. But hey, here's a paltry offering consolation prize—a one-shot story written by a friend of mine that was directly inspired by my Heroic Spirit interpretation of this "wonderful" guy! Honestly, I thought it was an excellently-written short story based on the character I designed (of course, based on an existing mythological character), and I feel that it's very under-appreciated. Here is the profile I made for my interpretation of the character as a Servant. Read in whichever order you want—the second link is a short article attempting to shed light on why the character would think and act the way he does in the story; the details in the profile could also be considered a slight spoiler to the story itself.

If you're interested in reading about what I had planned for the Fate/RETOLD Project, you should send me a PM. I've still got all my materials saved and would be happen to share them with you.

1998083

Wonderful! How fast is that in space..?

Well, considering there is no air resistance and only microgravity to worry about? Should be around 250–380 m/s (Mach 0.735–1.117) until the bullet hit something.

How much do you jizz..?

......Over what kind of time period are we talking?

Dear God, Kullervo would fit in almost too well with the Fate/stay cast. Fucking awesome, though. A tragic figure whose life is ruined by machinations that are (mostly) beyond his control, turned into total, army slaughtering badass with near godlike powers and a very loose grasp on morality and reality.

[The Sexy Assistant]

1998851 Well, Mach speed relates to the speed of sound. So unless you were treating mach speed as an integral unit, the Mach speed of any bullet in space should be zero, right..?

A week..?

I think you forgot a tag there.

[Permanent Temporary]

1999826
You are correct in that the speed represented by Mach 1 is not a constant, since it depends on the speed of sound through the medium; for example, the speed of sound through an iron rod is roughly 5120 meters per second (equivalent to Mach 15+ in air at sea level STP). The Mach number is viewed as a relative dimensionless quantity rather than a unit of measure based on the speed of sound in a medium, and for standard temperature and pressure (STP) conditions of air at sea level in the Earth's atmosphere is normalized at around 340.3 meters per second—for this reason, much of the time when "Mach" is used, it is often assumed that one is using the above measurement (340.3 meters per second) as a relative point for comparison. I've seen 343 meters per second used as a basis for comparison before as well.

the Mach speed of any bullet in space should be zero, right..?

The Mach number is defined as the velocity of the projectile (v) relative to the medium divided by the speed of sound for the medium (s). If space were a true vacuum, the pressure would be zero and thus the speed of sound would logically also be zero, which should result in "v/0 = Mach ∞". Although in reality, it would be left as "undefined"—but that's not as fun as saying "we're traveling at Mach infinity!"

HOWEVER—space is not a true vacuum. The pressure of space in intergalactic voids was actually measured to be 10^–17 pascals (the lowest pressure ever measured), as even between galaxies there are occasionally the odd hydrogen atoms here and there, technically meaning the intergalactic vacuum is a very tenuous gas. That means there could theoretically be a speed of sound in outer space, despite the standard belief being that sound will not carry over distance through space. However, I can't begin to tell you what that would be—obviously, this case is not going to follow the standard Earth logic concerning sound, given that it has such a low density (10^−18—10^−22 kg/m^3), and the rules are likely different from what they would be in a denser medium like air or water.

...I don't see what tag I might have missed. Everything seems in order.

1998851 Ah, everything makes sense now.

[MrZJunior]

So, we see that Shining Armor's shield spell provides some resistance against physical attacks. If memory serves it is quite rigid and would probably be stronger if he were at full power and not being drained by Chrysalis.

Now, if there were such a shield large enough to cover an entire country do you think it would be able to disrupt the trajectory of a nuclear reentry vehicle enough to significantly damage the strategic utility of ICBMs in a hypothetical conflict? Nuclear weapons definitely have some splash damage, but if they are struck off course hard enough they would loose their utility as anything other than terror weapons.

Furthermore, it is my understanding that nuclear weapons tend to be delicate and finicky machines, could an impact against our hypothetical shield be enough to disable a nuclear weapon?

[Permanent Temporary]

So, we see that Shining Armor's shield spell provides some resistance against physical attacks. If memory serves it is quite rigid and would probably be stronger if he were at full power and not being drained by Chrysalis.

But even then, the attacks it sustained were not exceptionally powerful. Even if we assumed that there were ten groups of twenty Changelings each weighing around 50 kg slamming themselves into the shield once every second at a speed of 20 meters per second, with each group's timing delayed from the last by a tenth of a second (meaning the total number of impacts per second is 200), their total impact power would be 2 megajoules per second, which is equivalent to 2 megawatts. 2 megawatts is pretty close to the maximum power output of the WWII-era P-51D Mustang fighter aircraft's Packard V-1650-7 liquid-cooled supercharged V-12 engine in "war emergency power" setting (1.3 megawatts). And even if I granted Sombra, who is between 2.4 meters and 8.5 meters tall (MLP can't do perspective consistency), a pony-like density (despite him reportedly being made of "shadow" and thus logically having no conventional measure of density since he's not made of legitimate matter anyways, or if we more reasonably assumed he was made of some kind of smog-like solid-liquid aerosol and thus had a density only somewhat greater than cooled air, 1.3–1.5 kg/m^3) scaled up from the average pony to his height, he would be about 250 kilograms in 2.4 meter form, and in 8.5 meter form he would be about 3200 kilograms; of course, this is scaling him up from ponies, density and volume in all, so it's a very rough estimate and is almost certainly wrong. At any rate, in order for the latter 8.5 meter tall version of Sombra to produce impact power comparable to the 200 changelings from above, he'd have to either strike the shield several times per second at a slower speed, or strike it approximately once per second traveling about twice as fast as the changelings.

Furthermore, in both cases, the maximum impact surface energy of the pony-like entity striking the shield with their head and barrel is only going to be within the realm of 25–35 joules per square centimeter—compared to something like a 5.56mm M855A1 bullet's maximum impact energy of 124–141.5 kilojoules per square centimeter, isn't very stressful to the shield (which is one reason why bullets have such incredible penetrative ability). The 25–35 joules per square centimeter rating means that the entire shield only needs to have the ability to withstand an impact greater 250–350 kilojoules across each area of one square meter every second to keep the Changelings and King Sombra out—yet 5.56mm bullets could easily punch through that shield, even though they couldn't completely break it and would only accomplish punching a ~6mm diameter hole though it for however long it remained open.

Now, if there were such a shield large enough to cover an entire country do you think it would be able to disrupt the trajectory of a nuclear reentry vehicle enough to significantly damage the strategic utility of ICBMs in a hypothetical conflict?

...An entire country? This has got to be a completely hypothetical case, because Shining Armor has never projected a shield over an entire country, never to my knowledge anyways. By the way I categorize things at least, a country-sized area is much bigger than a city-sized area, to the point that the results of calculations are magnitudes larger for country-sized areas compared to city-sized areas. Here's how I personally like to break down city and countries (and towns) into categories based on area:
• Town level: Starting at a 0.785 km^2 total area (1 km diameter) up to a 12.56 km^2 total area (4 km diameter).
• City level: Starting at a 78.5 km^2 total area (10 km diameter) up to a 1256 km^2 total area (40 km diameter).
• Country level: Starting at a 7850 km^2 total area (100 km diameter) up to a 3,140,000 km^2 total area (~2000 km diameter).
As you can see, the City's total area is 6.25–1600 times bigger than Town's total area, while the Country's total area is 6.25–40,000 times bigger than City's total area. Now, if we calculate the surface area of hemi-spherical domes able to cover each of them...
• Town Dome: 1.57–25.12 km^2 (0.5–2 km radius)
• City Dome: 157–2512 km^2 (5–20 km radius)
• Country Dome: 15,700–6,280,000 km^2 (50–1000 km radius)
As you can see, like before the City Dome's surface area is 6.25–1600 times bigger than Town Dome's surface area, while the Country Dome's surface area is 6.25–40,000 times bigger than City Dome's surface area. That's a large difference, especially on the upper end comparison—the largest countries dwarf the smallest cities.

NOTE: I typically consider any nation with a total area greater than 3,140,000 km^2 to be categorized as "Subcontinent level" instead—this group is exclusive to India, Australia, Brazil, United States, China, Canada, Antarctica, and Russia. Conversely, I categorize any country with a total area lower than 7850 km^2 within Metropolis, City, and Town levels. It doesn't mean I don't consider them to be countries, it just means I don't categorize them as "country-sized areas" because they fit more closely into some other category.

Now, since you mentioned a "reentry vehicle," I am assuming that the missile is a sub-orbital missile class nuclear weapon set to either detonate in surface strike or lower altitude air-burst... yes, striking the shield would destroy the missile—then again, ICBMs typically reach their targets traveling at several kilometers per second, so if it physically hit the shield, it's going to obliterate itself on impact (and probably shatter a sizable hole right through the shield from its pure impact energy alone). However, if we are using a country-sized dome, with a surface area of 15,700–6,280,000 square kilometers and a radius of 50–1000 kilometers, then... well, let me just tell you some interesting facts and I think you might start to see what I'm trying to get at.

• On Earth, the altitude at which the stratosphere ends and the mesosphere begins is typically 50 kilometers; the mesosphere lies above the maximum altitude for air-breathing aircraft and below the minimum altitude for rocket-engine orbital spacecraft.
• On Earth, the altitude at which the mesosphere ends and the thermosphere begins is typically at about 80 kilometers; the lower part of the thermosphere, 80–550 kilometers above Earth's surface, contains the ionosphere; additionally, the International Space Station orbits in this layer, drifting between 320–380 kilometers.
• On Earth, the altitude at which the thermosphere ends and the exosphere begins is typically at about 700 kilometers; this layer is a transitional zone between Earth’s atmosphere and interplanetary space, and covers all distances where particles are still gravitationally bound to Earth, extending out to half the distance to the Moon, about 190,000 kilometers.

So what's my point? Well, there is absolutely no fucking way that a country-sized shield would not be completely unmissable to our sensors. There is no fucking way we could fail to detect an energy signature that blatant and massive in scale. Hell, there is no fucking way we could fail to notice it visually as long as we got within a quarter of the planet's surface from it. It's just too freaking massive. A more realistic version of the dome would be much shorter, a hemi-ellipsoid that only extended maybe a few kilometers above the tallest point under the dome—however, since we've only seen Shining Armor make spherical shields, that's what I'm going to stick with.

Nuclear weapons definitely have some splash damage, but if they are struck off course hard enough they would loose their utility as anything other than terror weapons.

"Some splash damage", he says. Alright, let's take a look at the LGM-30G Minuteman-III land-based intercontinental ballistic missile in service with the United States Air Force Global Strike Command. It's equipped with three multiple independently target-able reentry vehicles (MIRV, although it can also be used as an MRV missile) each packing a 350 kiloton W78 thermonuclear warhead. Not seem impressive enough? Here are the results of three of these warheads detonating relatively close to each other at an airburst altitude of 1.8 kilometers.
Even if the shield can handle the fireball, overpressure blast, and possibly even the thermal radiation, I seriously doubt it has any hope of stopping the electromagnetic radiation, since it doesn't stop light from passing through.

Furthermore, it is my understanding that nuclear weapons tend to be delicate and finicky machines, could an impact against our hypothetical shield be enough to disable a nuclear weapon?

Like I said above, if an ICBM like the Minuteman-III impacted the shield without detonating first (which is pretty unlikely since, as I mentioned, it is pretty hard to believe we would fail to notice something that size, so we'd know to set the warhead off when it reached the shield), it would be physically obliterated, since it should be traveling around 7 kilometers per second (Mach ~20.6) at that time. And given that the W78 warhead weighs 320–365 kilograms, the kinetic energy from the impact alone will be about 7.8–8.9 gigajoules, equivalent to the explosive energy of ~2 tonnes of TNT, striking on an surface area of about 25 square centimeters, giving us an maximum impact surface energy of 313.6–357.7 megajoules per square centimeter (equivalent to 75–85 kilograms of TNT exploding across the area of a square centimeter). So, while the nuclear warhead didn't detonate, as long as the shield follows some kind of at least pseudo-scientific logic and doesn't fall entirely into the category of "bullshit magic", the warhead should almost certainly have blown a sizable hole right through the shield wherever it struck.

Thanks to certain fanfics I was wondering how would twilight sparkle (with power of 4 princesses) fare against some characters from bleach. (I'm sure if you wrote something on this it could be also used to compare her power with characters from other franchise too.) To be more specific: Ichigo prior to his battle with Ulquiorra, Ulquiorra (released), vasto lorde Ichigo, Ichigo when he was battling Aizen after he learned final getsuga tensou.

I'm aware that it is impossible to make 100% correct comparison since when you try to apply real physics to these battles they turn to be very inconsistent. (I'm sure the attack that would require most power in ts vs tirek wasn't that final beam but tirek punching ts through mountain especially since http://en.wikipedia.org/wiki/Impact_depth.)

I think that ts should be somewhere between Ichigo prior to Ulquiorra battle and released Ulquiorra.

I may post my own (not so scientific) analysis and you can just tell me your opinion on it if you would prefer that. I will wait until you reply to this because I don't want to spam your blog to much.

p.s. English isn't my first language so I'm sorry if some of the sentences are awkwardly written but this is the best I can do.

1.) Not a mountain—it wasn't big enough (it's only about 300 meters tall). It's more like a butte.
2.) Projectile depth doesn't work for Twilight Sparkle getting pushed through the "mountain", since she wasn't a projectile—she was constantly being pushed through. So the rock crush energy value is what's important. That energy would be total worth less than 100 tons of TNT in energy.
Meanwhile, Ichigo's physical attacks are in the dozens of kilotons of TNT range, at least.
3.) Speed would be a major issue:
Twilight Sparkle = probably Mach 2 at the most, not counting teleportation (since that isn't movement speed or reaction speed), which wouldn't even matter as you can see below.
Bankai Ichigo = at least Mach 10–20; TS likely won't even have time to react to Ichigo, and won't be able to see him when he's moving.

However, you shouldn't let this stop you from writing a story if you really want to.

I'm back, 45 weeks later, with a oh so philosophical and extremely important question. Not really.

How much pressure in pounds per square inch (psi) do you think an Equestrian mare can exert with her vagina? Assuming they have the same vaginal muscle control as real life mares, which can tighten up their vaginal opening to the point to where you can't put a finger through for the purpose of not having anything enter when they take a crap (lovely thought, isn't it?~).

Since Equestrian mares are smaller in size, have different proportions, and proportionally different strength values. As well as how much a earth pony would be able to exert, with say, about a ~1.75x-2x higher strength from their magical steroids boost.

(My face as I think of your reaction to this.)
i.imgur.com/gucKWxD.jpg

[Permanent Temporary]

2821254
According to earlier calculations, an Earth Pony mare is less than a sixth the volume and mass of a real pony (Haflinger), so assuming similar capacity (due to a lack of information otherwise), according to square-cube law the Earth Pony's strength should be less than a third. Even applying your completely arbitrary "~1.75x-2x magical steroids boost"... they should be a little over half (~0.5–0.6) the strength of a real Haflinger mare.

No, I'm not looking up the actual value in pressure. I've given you a factor, so you can look up a value for that on your own and simply multiply it by the factor. I'm not Googling that. Do your own damn dirty work.

*sadface*

[Paddle Steamer]

2821386 Oh, you changed some stuff, good thing I didn't start yet.

Even applying your completely arbitrary "~1.75x-2x magical steroids boost"

Unfortunately any set number for how much extra strength earth pony magic gives them will most likely always be arbitrary, as I find it doubtful the show writers are going to give a statement of how much it is. And the strengths in the show itself, like any child's cartoon really, fluxtuate constantly, because they have no set numbers and instead run on what the plot demands. As well as most likely some factor of Rule of Cool if it's meant to be neat.

So I decided I wanted a set range value, to make things more consistent for my stories and headcanon, given that all we know is earth pony magic gives them enhanced strength and some sort of connection with nature (which is even more vague, at least enhanced strength is a straightforward concept).

So I decided upon something I thought was reasonable enough, a range of, low: 1.5x, average: 1.75x, and high: 2x. Something that was still high enough for it to really make a difference as a defining factor of their race, while not making them so strong as to possibly enter the OP range.

Another thing that's also completely headcanon with my system, if you're interested, is that the magical strength increases or decreases dependent on the physical strength of the pony. So say, Octavia, a cellist whom probably isn't particularly physically fit is going to have a lower magical strength increase, probably closest to the low range, while a physically fit pony like Apple Jack or Big Mac will have one towards the high range.

This allows such ponies as AJ or Big Mac to be significantly stronger than even other earth ponies, more so than fitness would normally if they all had a fixed strength increase from their magic.

I'm curious as to what your personal headcanon for earth pony magic is? I mean yeah in debates and such you have to use canon, as arguing with headcanon is pointless and not going to get you anywhere, but that doesn't mean you don't have a personal headcanon I'm willing to bet.

[Permanent Temporary]

So I decided I wanted a set range value, to make things more consistent for my stories and headcanon

Hence why I said it was arbitrary. I didn't say it is necessarily bad or wrong per se, just that it is completely arbitrary.

Another thing that's also completely headcanon with my system, if you're interested, is that the magical strength increases or decreases dependent on the physical strength of the pony.

While I would tend to agree that physical health would likely have an effect on magical prowess, I don't think it would necessarily be a direct correlation. I don't believe that an ordinary healthy Unicorn pony like Lyra or Minuette would have less magical power than an extremely physically fit Earth or Pegasus pony like Big Mac and Bulk Biceps. Yes, I think that physically healthy ponies would tend to have magic reflecting their state of health, I don't believe that a pony can simply "weight lift" their way to higher magical prowess—the correlation between health and magic would only extend so far.

I'm curious as to what your personal headcanon for earth pony magic is?

I know, hence why I responded with how unfortunately that's most likely always going to be the case unless canon will actually give us a number. [insert laugh track here]

I don't believe that an ordinary healthy Unicorn pony like Lyra or Minuette would have less magical power than an extremely physically fit Earth or Pegasus pony like Big Mac and Bulk Biceps.

I believe I forgot to specify that I meant in regards to earth ponies in particular, since their magic is directly correlated with their strength, and not pegasi or unicorns.

Which I have different headcanons on their workings.
