How is the Three Gorge Dam made in China slowing down the speed of the Earth's rotation? What are the side effects?

 The largest dam in the world, this thing can hold up to 42 billion tons of water in its reservoir.

Now, you might think that water is just water, and it doesn't matter where it is. But you'd be wrong.

Water has mass, and
mass has gravity. And gravity affects how fast the Earth rotates around its axis.

You see, the Earth is not a perfect sphere. It's slightly flattened at the poles and bulging at the equator.

This is because of the centrifugal force caused by its rotation. The faster the Earth spins, the more it flattens out.

But when you move a lot of water from one place to another, you change the distribution of mass on the Earth's surface.

And that changes how much centrifugal force there is at different points on the planet

The Three Gorges Dam has moved a lot of water from lower altitudes to higher altitudes, closer to the Earth's axis of rotation.

This means that the water in the reservoir has less centrifugal force than before, and it pulls more on the Earth's core. This makes the Earth more round in the middle and more flat on the top.

And what happens when you make something more round?

It slows down its rotation.

That's right, the Three Gorges Dam has slowed down the Earth's rotation by increasing its moment of inertia.

The moment of inertia is a measure of how hard it is to change an object's angular motion.

The more mass an object has near its axis of rotation, the higher its moment of inertia, and the slower it spins.

Now, the spin is not much slower. According to NASA scientists, the Three Gorges Dam has increased the length of a day by only 0.06 microseconds.

That's 0.00000006 seconds. You can't even notice that with your naked eye.

What is the most rare and expensive metal on earth?

 One of the most rare and expensive metals on Earth is rhodium. Rhodium is a member of the platinum group of metals and is known for its remarkable resistance to corrosion and its reflective, silvery-white appearance. It is often used as a coating for jewelry and is also employed in catalytic converters for automobiles.

The rarity and high demand for rhodium contribute to its high market value. Prices for rhodium can be significantly higher than those of other precious metals such as gold or platinum. The value of rhodium can fluctuate based on market conditions and industrial demand.

It's important to note that the status of the rarest and most expensive metals can change over time due to factors such as new discoveries, technological advancements, and shifts in industrial demand. For the most current and accurate information on precious metal prices and rarity, it is advisable to consult reliable financial sources or market reports.

Rhodium is very scarce and difficult to extract. It is usually obtained as a by-product of mining and refining platinum or palladium. The price of rhodium fluctuates depending on the supply and demand factors. In 2020, rhodium reached a record high of over $13,000 per troy ounce, making it more than 10 times more expensive than gold. But rhodium prices can also drop sharply due to economic downturns or technological changes

Is there an asteroid on its way to Earth in 2029?

 As of my last knowledge update in January 2022, there is no known asteroid on a collision course with Earth in 2029 that poses a significant threat. One notable event associated with 2029 is the close approach of the asteroid Apophis. Apophis is a near-Earth asteroid that gained attention due to initial calculations suggesting a small probability of a potential impact during its 2029 pass. However, subsequent observations and refined calculations have ruled out any impact risk for that particular encounter.

Astronomers use advanced telescopes and computational models to track the trajectories of near-Earth objects (NEOs), identifying potential risks and mitigating them through ongoing observation and analysis. As of now, no known asteroid is expected to impact Earth in 2029. Nevertheless, continuous monitoring of celestial bodies, especially NEOs, remains a crucial aspect of planetary defense efforts.

It's important to note that new discoveries can occur, and our understanding of asteroid trajectories can evolve over time. To stay updated on the latest information about potential asteroid threats, it is recommended to check with reputable space agencies such as NASA, the European Space Agency (ESA), or other organizations dedicated to planetary defense. They provide real-time data and assessments regarding any potential impact risks.

Is it true that Jupiter is so large that it does not orbit around the sun?

No, it is not true that Jupiter does not orbit around the Sun. In fact, Jupiter is a massive gas giant that is a prominent member of our solar system, and like all other celestial bodies, it orbits the Sun. Jupiter's immense size, in fact, contributes to its significant gravitational influence within the solar system. Its gravitational pull affects the orbits of other planets and celestial bodies, playing a crucial role in the dynamics of the solar system.

Jupiter follows an elliptical orbit around the Sun, much like the other planets in our solar system. This gravitational dance is governed by the laws of celestial mechanics, particularly Kepler's laws and Newton's law of universal gravitation. The gravitational force between Jupiter and the Sun keeps the planet in its orbit, preventing it from drifting off into space. While Jupiter's immense mass does have a profound impact on the solar system, its orbit around the Sun remains a fundamental aspect of its celestial behavior.

Jupiter's orbit around the Sun takes approximately 11.86 Earth years to complete, and its elliptical path means that its distance from the Sun varies during this orbital journey. Despite its enormous size and mass, Jupiter is bound by the gravitational forces of the Sun, just like any other object in the solar system. The intricate interplay of gravitational forces is a testament to the delicate balance that characterizes the celestial choreography of our solar system, with each celestial body, including Jupiter, playing a vital role in maintaining this cosmic equilibrium.
