The shell yould just vaporise in the atmosphere (maybe with a big bang) but nothing more. The sheer amount of energy the shell would have to travel with a 'good percentage the speed of light' would tear the fabric of given shell apart ... as for antimatter ... the shell it self would implede the moment the antimatter is inserted !

If eve followed real physics those shells would go for 1000km (well actually much much much much much further) in space but they don't. I wast saying real 125mm shells couldnt do it, i'm saying the ones in eve shouldnt be able to. Because in eve space the same size shells go to around 20-30km, unless they are shooting something on the ground, then magically they have a 1000km optimal.. Wheres my atron with a 1000km optimal please?

I get the size difference of spaceships compared to men. It still makes no sense when placed into EvE.

I'm not saying the games to hard or easy or that i want it harder or easier. I'm saying that having such a massive performance boost on a small gun just because its facing down is a MASSIVE imersion breaker that doesn't "fit" with the rest of the game at all.

As far as orbital bombartment goes .. anyone remember 'Babylon 5' ? I think it was third or forth season .. they flung asteroids on planets ... maybe this would be some new reason to fit tractor beams on capitals ? :) .. And for planetary defense to have enough miners at hand to remove belts before the enemy arives

I can't see any reason to risk 200-2000 millions worth battleship for a planet which can bring 50mil/month of "income" - or for ridiculous 12x12 surface battle with 5mil payout (5mil = my guess about Dust payouts).

About size. EVE destroyers are comparable to modern naval carriers and WW2 battleships. I.e. they are huge.

P.S. Asteroids bombardment = "mass driving" is too destructive.

Ahm .. YOU brought the RL-Destroyers shell into discussion .. and in RL anything filled up with antimatter would just implde AND a shell (short of 1KM diameter) will just vaporice because of the air around us .. otherwise you wouldn't be able to go around on the surface due to tiny asteroids and space-trash hitting earth all time.
And yes story ... and I still don't understand why my stealth-BOMBER cannot use its BOMBS for orbital BOMBartment ... though I have the skill BOMB deployment .. but that might be something completely different

assuming the payload of the destroyer shell is a cylinder with 115mm diameter and 600mm height, its volume would be pi*600mm*(100mm/2)^2 = ~4,712,389mm^3

It would reasonable to use some relatively heavy antimatter as ammunition, for the sake of the argument lead ions will do.

Lead has a density of 11,340 kg/m^3 or 1.1340 *10^-5 kg/mm^3, therefore our (anti-)lead cylinder would have a mass of ~53.44kg.

Using E = m*c^2 one antimatter shell would be converted into ~4.8*10^18 joules, the equivalent of 1,148 megatons of TNT.

The most powerful nuclear weapon detonated on earth so far had a yield of 57 megatons.

One single destroyer shell - the equivalent of 20 extremely powerful hydrogen bombs.

Those DUST mercs better watch out.

Does one gram of antimatter contain the energy of a 20 kilotonne nuclear bomb?

Twenty kilotonnes of TNT is the equivalent of the atom bomb that destroyed Hiroshima. The explosion of a kilotonne (=1000 tonnes) of TNT corresponds to a energy release of 4.2x1012 joules (1012 is a 1 followed by 12 zeros, i.e. a million million). For comparison, a 60 watt light bulb consumes 60 J per second.

You are probably asking for the explosive release of energy by the sudden annihilation of one gram of antimatter with one gram of matter. Let's calculate it.

To calculate the energy released in the annihilation of 1 g of antimatter with 1 g of matter (which makes 2 g = 0.002 kg), we have to use the formula E=mc2, where c is the speed of light (300,000,000 m/s):

E= 0.002 x (300,000,000)2 kg m2/s2 = 1.8 x 1014 J = 180 x 1012 J. Since 4.2x1012 J corresponds to a kilotonne of TNT, then 2 g of matter-antimatter annihilation correspond to 180/4.2 = 42.8 kilotonnes, about double the 20 kt of TNT.

This means that you GÇÿonlyGÇÖ need half a gram of antimatter to be equally destructive as the Hiroshima bomb, since the other half gram of (normal) matter is easy enough to find.

At CERN we make quantities of the order of 107 antiprotons per second and there are 6x1023 of them in a single gram of antihydrogen. You can easily calculate how long it would take to get one gram: we would need 6x1023/107=6x1016 seconds. There are only 365 (days) x 24 (h) x 60 (min) x 60 (sec) = around 3x107 seconds in a year, so it would take roughly 6x1016 / 3x107 = 2x109 = two billion years! It is quite unlikely that anyone wants to wait that long.

how does scientific progress prevent the entire battlefield from being vaporated when treated to the equivalent of 1 gigaton TNT?

I suspect the magnetic bottle runs out of energy to susain it's containment field, in which case the shell would just evaporate. I'd do it the same way, it's a nice safety mechanism to prevent stray shots hitting anything You dont want to hit, outside of a certain range ofc.

An object in motion remains in motion unless acted on by an outside force.

optimal range + falloff in EVE isn't a measure of how long your round last before disintegrating (except with blasters) it's a measure of how far out the ship can reliably hit stuff with that kind of gun before things get so extreme that any hit you did score would constitute divine intervention.

Fire a hybrid round, and it will fly off into space to ruin somebody's day, somewhere, sometime. If you got things right, the person whose day it ruins is your intended target's.

Make the thing work good first, then go bigger. Not that hard to figure out.

That said it would be awesome to fire 8 bus-sized projectiles into a planet

People certainly take their space physics very seriously...

This iteration of Orbital Bombardment is focused on the Tactical Strike variant which is performed with specialized ammo for small turret based weapons. Each turret category has a specialized ammo type: - Hybrids: Tactical Hybrid S - Lasers: Tactical Laser S - Projectiles: Tactical EMP S

The hybrid strike delivers a nice spread of high-damage rounds that are effective against infantry and vehicles. Laser strikes have a more focused area and are good for taking out installations or heavy vehicles. The EMP strike does a massive amount of damage to shields in a large area, but it will not damage armor, so it's good against heavily shield tanked targets.
