The Biggest Economies in the World

If you want to learn more about the biggest economies in the world, read our article. During the last two decades, advanced economies of the world have faced slower growth than that of developing economies. The cause can be found in emerging economies such as India and China.

What Are the Biggest Economies in the World?

- The biggest economy in the world is the USA. Nevertheless, the USA economy share in the world PPP and GDP has decreased. This happened because of crisis, but other emerging economies have had certain influence, too.

- Japan economy is one of the world’s largest economies. The country has faced stagnation during the mid-2000s, but the economy has recovered since then.

- The EU economy has a considerable share in the world GDP. Many developed countries contribute to the power of the EU economy, but there are also some less developed countries in this community. The EU has faced certain economic and political crisis, but it has recovered. However, its future power is yet to be seen.

- China is on the right track to become the world’s biggest economy. According to what some exerts say, this will probably happen by 2017.

- India is another big economy. According to estimations, it will probably be bigger than Japan economy in a year or two. India has a lot of potential, perhaps even more than China. The population of India is younger and its growth is faster.

- According to economy experts, Russian economy will be greater than Germany’s by 2020. This big country has an important role in the world’s economy and politics, so there is no reason to doubt this estimation.

- Brazil is likely to overtake France and UK economy. By 2020, this economy will probably be the seventh in the world. It has a lot of potential.

- Mexico will probably beat Italy by 2020. Today, Italy is ranked 10th, but Mexico is likely to overtake this position. The population of Mexico is growing and so as its potential.

As we know, economy is highly dependant on many factors, one of which is politics. We cannot predict future trends, but we can use logics and knowledge to make some estimation. Developed countries will probably stay highly ranked, but the question is: what will happen to developing countries? The difference between developed and developing world is huge. Efforts should be made in order to include these countries in the world economy and help them achieve higher standards.

The Biggest Bridge in the World

What is the biggest bridge in the world? The Pearl Bridge, also called “The Akashi-Kaiky Bridge” is the longest suspension bridge in the world. It is 1991 meters long. The bridge is located in Japan. It was built in 1998. The Pearl Bridge connects the Kobe City to Awaji Island. In fact, this bridge is a part of the highway Honshu-Shikoku.

The Longest Bridge in the World – History

Before the bridge was made, the passengers used ferries to cross the Asahi Strait. This waterway was dangerous, especially during storms. The storms in this area can be very aggressive. In 1955, a couple of ferries sank because of storms. 168 people got killed in these accidents. Japanese government had to do something to solve this problem and prevent future accidents. However, the construction works began in 1986, and the Pearl Bridge was finally opened in 1998. This was the best way to make the traffic safer and faster. This strait is one of the international waterways, and it has to be safe.

The Pearl Bridge has 3 spans. The bridge is designed to stand very strong wind, earthquakes and sea currents. It has two supporting towers that are nearly 299 meters above the sea. More than 350 000 tons of concrete were needed for each anchorage. 300 000 kilometers of steel cables were used.

The Pearl Bridge has 1737 lights. 115 lights are used for main towers, 1084 are used for cables, 132 lights are used for anchorages and 405 illuminations lights are used for girders. The bridge looks beautiful, especially when the lights are on. Various combinations are used for illumination. During the national holidays, different light patterns are used.

The bridge construction was very expensive. The entire cost will be repaid simply by charging a toll. Many people use the bridge, so eventually, this cost will repaid.

Here are several long bridges, some of which are in the United States.

Seven Mile Bridge is located in Florida. It connects Florida to the Gulf of Mexico. This bridge is one of the major bridges in the United States.

San Mateo-Hayward is located in California. This bridge is also known as San Mateo. It connects the East Bay to San Francisco Peninsula.

Rio Niteroi Bridge is located in Brazil. The construction work started in 1968, and the bridge was finally finished in 1974.

Penang Bridge is located in Malaysia. It is nearly fourteen kilometers long.

The Biggest Known Star in The World

The biggest known star in the space is VY Canis Majoris (Big Dog on Latin), red hypergiant. It is approximately 2000 times larger then our Sun ~2 700 000 000 km across. It is located in constellation Canis Major. Distance from Earth is nearly 4900 light years. Even VY Canis Majoris is a 500 000 times brighter then our Sun, most of its light is absorbed by a cloud of dust particles which are ejected from the star over the past thousand years….

This ejection of materials suggest that this star is in its ending life stage which means it will eventually explode in supernova and remnant material will became a black hole…

Even the largest known VY Canis Majoris is not the most visible star. It is not the largest star by mass – we already mentioned it ejected much of its mass to space…

Jerome Lalande, the French astronomer is credited as person who discovered VY Canis Majoris. He mentions it in one of his entries in his star catalogue, as a 7th magnitude star. Entry is dated at March 7, 1801.
