I posed the following question to the Claude AI chat bot.

Suppose an asteroid made of pure gold was several miles wide made of many times more gold than all of Earth’s supply. Also suppose it broke into a multitude of smaller pieces and they showered down uniformly all over the world so that everyone became equally and suddenly wealthy with gold. What would happen to the monetary systems of the world?

Gold Asteroid Economic Scenario

If an asteroid made of pure gold showered equally across Earth, several dramatic economic effects would follow:

Immediate Impact

Gold’s value would plummet almost instantly.
The price might drop from thousands per ounce to nearly worthless.
Everyone having gold would make it common, not precious.
Gold-backed currencies would face immediate crisis.
Central banks holding gold reserves would panic.

Supply and Demand Effect

The gold supply would increase by many thousands of times.
When supply greatly exceeds demand, prices collapse.
What was once rare would become ordinary.
Gold might become as common as aluminum or copper.
Jewelry stores would close as gold becomes worthless.

No Change in Real Wealth

Having more gold wouldn’t create more food, houses, or goods.
The same amount of actual resources would still exist.
Everyone would have gold, but nothing new would be produced.
Gold would simply stop functioning as a store of value.
Real wealth is productive capacity, not metal.

New Currency Systems

Countries would quickly abandon gold standards.
Paper and digital money would completely disconnect from gold.
Governments would need to establish trust in non-gold currencies.
Bitcoin and other limited-supply assets might gain value.
New scarce materials might replace gold for value storage.

Price Instability

Markets would face extreme volatility.
Gold mining companies would collapse overnight.
Industries using gold for electronics might benefit.
Luxury goods markets would need to find new status symbols.
Financial instruments based on gold would become worthless.

Psychological Impact

People might lose faith in traditional stores of value.
Economic anxiety would spread despite everyone having gold.
Trust in financial systems could erode.
The concept of “precious metals” would need redefining.
Society would need to adjust to gold being common.

Long-Term Adaptation

Gold might find new industrial uses at lower prices.
Monetary systems would stabilize around non-gold standards.
New scarcity markers would emerge for wealth storage.
Economic history books would mark this as a defining event.
The world would continue, but with different value symbols.

My wife posed a slightly different scenario to her favorite chat bot ChatGPT.

Suppose a large asteroid made of solid gold were to land gently on Earth, what would happen?

That’s a great thought experiment! If a large asteroid made of solid gold were to land gently on Earth, several interesting things would happen—geophysically, economically, and geopolitically. Let’s break it down:

1. Physical Characteristics

Density of gold: Gold is very dense—about 19.3 g/cm³, over 2.5 times denser than rock, and nearly 20 times denser than water.
Massive weight: Even a relatively small gold asteroid (say, the size of a football field) would be extremely heavy, potentially weighing millions of tons.
Local effects: If it landed gently, the main concern wouldn’t be destruction, but ground compression, subsidence, and localized seismic activity due to the sheer weight. It could deform the crust beneath it.

2. Economic Impact

Massive drop in gold value: Gold’s price is high mainly because it’s rare. If thousands of tons of it suddenly became available:
- Gold markets would crash.
- It might become as cheap as common metals like copper or even cheaper.
- Fortunes would disappear overnight, and industries based on gold mining and investment would collapse or radically transform.

3. Technological and Industrial Effects

Gold has great properties: it’s highly conductive, corrosion-resistant, and easy to work with.
If it became cheap, we’d likely start using it for:
- Widespread electronics
- More durable aerospace or medical components
- Even luxury architecture (think gold wiring, not gold wallpaper)

4. Geopolitical Fallout

Where it lands would matter:
- The owning country might become the focus of intense global pressure—both diplomatic and possibly military.
- International treaties or interventions might try to seize, share, or control the asteroid.
Could destabilize economies tied to gold reserves.

5. Scientific Curiosity

If the gold asteroid formed in space, it might carry unique isotopic ratios or trace elements, offering clues about the early solar system.
Could reignite interest in space mining if it seems gold-rich asteroids are common.

In short: no explosion, but the ground sinks, gold crashes, geopolitics flare up, and tech evolves—a quiet arrival with loud consequences.

Responses by each chat bot included the categories and bullet points as you see them. I asked ChatGPT to generate the image.

In late December, the Sun was low in the southern sky for those of us in the northern hemisphere. As the weeks and months passed, the Sun crossed the sky at higher altitudes. By late June, it reached its highest arc before starting downward again. The low point in December is the Winter Solstice while the high point in June is the Summer Solstice.

Imagine placing a south pointing camera with a very accurate clock timer in a permanent location to record the Sun’s altitude in the sky every week or so at noon for an entire year. The series of photos would record the vertical change of the Sun as you would expect. But, another thing would be obvious in the photos. The Sun would also show changes in horizontal position in the photos. Here is a good example made by Giuseppe Petricca from Sulmona, Abruzzo, Italy. This figure is called an Analemma.
