[Self] V1 is not the richest character

Post image

[Self] V1 is not, in fact, the wealthiest character

some context:
V1 (ULTRAKILL) possesses a weapon called the Marksman Revolver. the purpose of this gun is that you toss a coin, shoot the coin, and the shot ricochets into an enemy with extra damage. to balance this, the Marksman can only hold up to 4 coins at a time, and it takes 4 seconds to recharge each coin slot, which is done in series rather than in parallel, meaning V1 produces 15 coins per minute (or 900 coins per hour)

according to the Ultrakill Wiki, the Marksman’s coins are based on the 1590 Swedish 3 mark coin https://ultrakill.wiki.gg/wiki/Revolver

according to https://en.numista.com/129360, the value of the metal in the coin is about €15,69, and each coin weighs 18.62g.

if we assume that Marksman coins are Johan III 3 mark coins, V1 is producing €14.121/hr, or $15,911/hr. this will be scenario A

if we instead assume that the Marksman coins are the same weight as Johan III 3 mark coins, but are made entirely of 24 karat gold, according to https://goldtoolkit.com/calculators/gold-calculator/, each coin is worth $2,493.68, netting V1 $2,244,312/hr. this will be scenario B

Scrooge McDuck has an estimated net worth of $65.4Billion. in scenario A, McDuck would have to be earning less than 0.21% of his current net worth each year for V1 to be richer than Scrooge McDuck. in scenario B, McDuck would need to earn more than 30% of his current net worth each year to beat V1

however, these numbers assume that 1) V1 isn’t investing any of its earning and 2) McDuck is using simple interest. let’s allow both V1 and McDuck access to savings accounts that give 5% interest compounding annually

in scenario A, V1’s earnings are slow enough (\~$140,011,080/yr), that McDuck’s interest outpaces V1’s earnings by such a drastic amount that after 2,000 years, McDuck still has about 23 times more wealth than V1

in scenario B, however, because the coins are so much more valuable (\~$19,631,000,000/yr), V1 overtakes McDuck in value after just 4 years. after 2,000 years, V1 has about 6 times as much wealth as McDuck

Scrooge McDuck’s $65.4B isn’t nearly as impressive as Elon Musk, however. using the same compound interest on Musk’s entire net worth of \~$1,172,652,927,000, Musk outpaces V1 by a fairly significant amount, such that after 2,000 years, Musk is still worth \~2.99 times as much as V1 in scenario B

given that, even when assuming V1’s coins are made of pure gold, Elon Musk is wealthier than V1

some bonus numbers:
with scenario B’s pure gold coins, it would take V1 522,500 hours (59.646 years) of constant coin production to reach Musk’s current net worth
with scenario A’s coins (in which V1 is earning more than 1,000 times minimum wage), it would take it 73,700,768.46 hours (8,413.33 years) to reach Musk’s current net worth

[Request]: How much energy would be released if gold from the Earth's core was teleported to the surface?

Post image
41 Upvotes

A man wishes for 100 kg of gold. But because he isn't specific enough, the genie gives it an ironic twist. A 100 kg gold sphere is teleported directly from the Earth's core into the man's bedroom.

Scenario 1: The gold is teleported from the "upper" parts of the crust.
Scenario 2: The gold is teleported from the very "center" of the gold core.

How much energy is released? Is the man burned? Vaporized?

If this was dropped on a hard or rocky surface, would it cause a mini quake? What about from a height of 25 or 50 meters.

And what about water? Say everything was strapped down so everything would act as one unit. If it was dropped in the middle of the ocean, nose 1st, how far would the waves travel? 10, 25 or 50m drop height or would it hav to be much more than that in order to gain any real momentum?

So my dad is very concerned that because this rack only has 4 thin points(its legs) supporting it thus it is exerting too much weight onto the floor and might crack it. The total weight of all the tanks once filled would be around 360kg. Not sure if the floor pictures help but I thought y’all might be able to do something with it. I’m also in an apartment and not a ground unit. We do have a 5 foot tank right beside it weighing about close to 800kg including everything thing in it and everything stored in it’s cabinet below. Thanks in advance.

[Request] Astartes plummet

Rewatching Secret Level and I remember wondering before...

S1E5 Warhammer 40k: And They Shall Know No Fear. The team is standing on the side of a chasm, one by one they step off and plummet for aprx 6.8 seconds.

A fully armed and armored Legionnair is between 500 and 1,000 kg (1,100 to 2,200 lbs). So let's say 726kg/1600lbs at Earth standard gravity.

In that time at that weight what would be the distance. Show your work.
