Day Six: ...Insert Evil Laughter then serve cold

So,we're nearly to our first skirmish with the Exams and what do you think I'm currently doing? Well,I'm trying to determine the optimal parameters of a impact event on my homeland's capital in order to erase it along with most of its population out of the planet.... You thought that I was studying?! How little do you know me.... SOOO,anyway, for now the best(or worst depending on where do you reside) option is a 70 meter pure tungsten projectile impacting at at least 45' at a velocity of around 16.8 at impact with an estimated explosive equivalent of ~89.3 Megatons(1.80 Tsar Bombs),which'll produce a 3.007(diameter)x0.600(depth) km crater together with an 20s earthquake rated at ~6 on the Richter scale with a potential of 6 to 7 on the Mercalli scale at 20km(an arbitrary boundary of our target due to the desire of the crazy genius[read me] to optimally erase Sofia from the face of the planet) and also together with second degree burns on the exposed parts of the body + some flash fires.... Nice....
The only problem with this is to actually create this impact event,but as a lowly 1st year Economics student I find it just a tad impossible,but one can hope,right? If someone like Ted Turner or Bill Gates throws some money my way,though, it wont be that impossible...
I'll only need some 1436755.04 cubic meters of Tungsten(some 27657534.52 tonnes of Tungsten(or 27.658 Megatons)) plus some boosters,which for the sake of simplicity wont be taken into account in the final damage estimate,which'll propel the projectile on a short trip 'round the Moon(to propel it to the required 17km/s orbital velocity) an' back... Smack in the middle of Sofia...... Nice......Expensive and/or Impossible.... But NICE....
Of course,there might be some problems - funding,ethical and moral implications (nah,not really) and logistics,but I don't care.... I(and most likely everybody in Bulgaria who's not living in Sofia) want to see a big friggin' bullet drop from the skies and effectively erase this infection from the face of the world... Some critics might suggest it'd be better to simply buy a second-hand Russian warhead and detonate it in or above the city... My response? - FUCK YOU,after years of Fallout 1'n'2 I learned something important - NUKES ARE BAD('n' for pussies)... I mean it too... Hell,if I really put my back into it,for a fraction of the costs only for the boosters I'd successfully create a Manhatton Project times 50...but that's not the way...and it's not that spectacular as well... I mean friggin' space bullets,guys!
So,errm,yeah,I think I'm losing it turbo-big time... and it wont be pretty,but still if someone discards all logic and/or thinking at large,it sounds kinda cool... Anyway,I think I'm gonna leave now to watch something decidedly non-violent to return back to sanity(not likely,but it's worth a try) and then dinner...
bk109 out and about in the secret underground volcano-top evil lair of EEEEVIIIILLLLLL
PS.Here's what I'd want from the GOD as a X-mas or B-Day present...
Impact Event Sofia,Bulgaria(insert date,God)

Distance from Impact: 20.00 km = 12.42 miles

Projectile Diameter: 70.00 m = 229.60 ft = 0.04 miles

Projectile Density: 19250 kg/m³

Impact Velocity: 17.00 km/s = 10.56 miles/s

Impact Angle: 45 degrees

Target Density: 2500 kg/m³

Target Type: Shithole of the planet/Capital city of Bulgaria

Energy:

Energy before atmospheric entry: 5.00 x 10¹⁷ Joules = 1.19 x 10² MegaTons TNT

The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 4.4 x 10³years

Atmospheric Entry:

The projectile lands intact, with a velocity 16.8 km/s = 10.4 miles/s.

The energy lost in the atmosphere is 1.24 x 10¹⁶ Joules = 2.97 x 10⁰ MegaTons.

Major Global Changes:

The Earth is not strongly disturbed by the impact and loses negligible mass.

The impact does not make a noticeable change in the Earth's rotation period or the tilt of its axis.

The impact does not shift the Earth's orbit noticeably.

Crater Dimensions:

What does this mean?

Transient Crater Diameter: 2.46 km = 1.53 miles

Transient Crater Depth: 0.869 km = 0.539 miles

Final Crater Diameter: 3.07 km = 1.91 miles

Final Crater Depth: 0.655 km = 0.407 miles

The crater formed is a simple crater

The floor of the crater is underlain by a lens of broken rock debris (breccia) with a maximum thickness of 304 m = 996 ft.

The volume of the target melted or vaporized is 0.00307 km³ = 0.000735 miles³

Roughly half the melt remains in the crater

Thermal Radiation:

What does this mean?

Time for maximum radiation: 0.0937 seconds after impact

Visible fireball radius: 1.54 km = 0.958 miles

The fireball appears 17.5 times larger than the sun

Thermal Exposure: 5.67 x 10⁵ Joules/m²

Duration of Irradiation: 20.5 seconds

Radiant flux (relative to the sun): 27.7

Effects of Thermal Radiation:

Much of the body suffers second degree burns
Deciduous trees ignite

Seismic Effects:

What does this mean?

The major seismic shaking will arrive at approximately 4 seconds.

Richter Scale Magnitude: 6.0

Mercalli Scale Intensity at a distance of 20 km:

VI. Felt by all, many frightened. Some heavy furniture moved; a few instances of fallen plaster. Damage slight.
VII. Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken.

Ejecta:

What does this mean?

The ejecta will arrive approximately 64 seconds after the impact.

Average Ejecta Thickness: 4.07 cm = 1.6 inches

Mean Fragment Diameter: 1.33 m = 4.37 ft

Air Blast:

What does this mean?

The air blast will arrive at approximately 60.6 seconds.

Peak Overpressure: 38700 Pa = 0.387 bars = 5.49 psi

Max wind velocity: 79 m/s = 177 mph

Sound Intensity: 92 dB (May cause ear pain)

Damage Description:

Multistory wall-bearing buildings will experience severe cracking and interior partitions will be blown down
Wood frame buildings will almost completely collapse.
Glass windows will shatter.
Up to 90 percent of trees blown down; remainder stripped of branches and leaves.
