Some estimates put it at 100 kilotons, which would be five times more powerful than Fat Man, the bomb dropped on Nagasaki by the US in 1945 and which killed 70,000 people instantly. But it still pales in comparison to the largest man-made explosion ever on Earth - the Soviet Union's Tsar Bomba - King of Bombs - detonated in 1961 in the height of the nuclear arms race. That hydrogen bomb unleashed a staggering power of 50,000 kilotons, or 50 megatons.

Was Donald Trump’s January 3 drone assassination of Major-General Qasem Soleimani the first step in turning the simmering cold war between the United States and Iran into a hot war in the weeks before a US presidential election? Of course, there’s no way to know, but behind by double digits in most national polls and flanked by ultra-hawkish Secretary of State Mike Pompeo, Trump is a notoriously impetuous and erratic figure.

In recent weeks, for instance, he didn’t hesitate to dispatch federal paramilitary forces to American cities run by Democratic mayors, and his administration also seems to have launched a series of covert actions against Tehran that look increasingly overt and have Iran watchers concerned about whether an October surprise could be in the cards.

Much of that concern arises from the fact that, across Iran, things have been blowing up or catching fire in ways that have seemed both mysterious and threatening.

In their hunger for power, humans have always searched for the perfect weaponry. Empires carved out in history were often the result of strategic planning, political ingenuity, and the most sophisticated warfare of their time. The careful selection of weapons at times proved to be the crucial difference between winning a battle or being slaughtered on the field. The earth has been bled upon during times of war from one century to another, the only difference being the style and choice of the weapon wielded.. very weapon is made with a specific purpose in mind. Weapons are constantly evolving to meet the needs of the warriors who wield them. Sometimes though, these needs produce weapons that, while no less efficient at executing their purpose, are ultimately quite unique.

An atomic bomb uses either uranium or plutonium and relies on fission, a nuclear reaction in which a nucleus or an atom breaks apart into two pieces. ... The hydrogen bomb relies on fusion, the process of taking two separate atoms and putting them together to form a third atom...

The Cold War was a lengthy struggle between the United States and the Soviet Union that began in the aftermath of the surrender of Hitler’s Germany. In 1941, Nazi aggression against the USSR turned the Soviet regime into an ally of the Western democracies. But in the post-war world, increasingly divergent viewpoints created rifts between those who had once been allies.

The United States and the USSR gradually built up their own zones of influence, dividing the world into two opposing camps. The Cold War was therefore not exclusively a struggle between the US and the USSR but a global conflict that affected many countries, particularly the continent of Europe. Indeed, Europe, divided into two blocs, became one of the main theatres of the war. In Western Europe, the European integration process began with the support of the United States, while the countries of Eastern Europe became satellites of the USSR.

Comparing the power of conventional military forces is quite complicated, which is part of what makes the annual Global Firepower rankings so noteworthy. China, for instance, has only 1 operational aircraft carrier to the US’s 11, but the People’s Liberation Army-Navy is testing its second carrier at sea and has plans to build more. The US is locked in an escalating face-off with top rivals Russia and China. But head-to-head comparisons of military strength are hard to come by.

The 2020 military strength ranking brings the USA in the first place of the list, the Russia second and the China third. The USA is ranked first out of 138 countries holding a PwrIndx rating of 0.0606. The United States retains its top spot as the undisputed military power in the world – both numerically and technologically. Total military personnel of USA is estimated at about 2,260,000 while the airpower total strength rating is 13,264, the highest among the 138 countries of the list.

The U.S.-made FGM-148 Javelin is one of the premier portable anti-tank missile systems in the world. It’s also an expensive piece of kit, with each missile typically costing more than the targets it eliminates. Here's How Powerful is America's Javelin Anti Tank Missile

The Vietnam War was a long, costly and divisive conflict that pitted the communist government of North Vietnam against South Vietnam and its principal ally, the United States. The conflict was intensified by the ongoing Cold War between the United States and the Soviet Union. More than 3 million people (including over 58,000 Americans) were killed in the Vietnam War, and more than half of the dead were Vietnamese civilians. Opposition to the war in the United States bitterly divided Americans, even after President Richard Nixon ordered the withdrawal of U.S. forces in 1973. Communist forces ended the war by seizing control of South Vietnam in 1975, and the country was unified as the Socialist Republic of Vietnam the following year.

If you have a fascination with fighter jets, chances are you’ve always wanted to strap into some of the most dynamic aircraft in the world and take them for a whirl yourself. That’s probably not going to happen in real life. So why not take to the skies in video games?

Flight simulators are the perfect option for aviation enthusiasts who are stuck at home. You can take control of your favorite plane with true-to-life cockpits, fly in and out of popular airports, navigate real-life weather models, and experience incredibly detailed 3D graphics.

There are many flight simulators on the market to choose from. Some simulators are incredibly intricate and authentic with a steep learning curve, and others are a bit easy to jump straight into.

As the United States enters an election year, prospects for global stability remain uncertain.  President Trump’s foreign policy stood at odds with those of his predecessor, and will likely a central point of contestation in the election.  At this point, several crises might emerge that would not only turn the election, but potentially bring about a wider global conflict. WORLD WAR 3 fears were ignited across the globe just a few days into 2020 and now they have been sparked again. But which five places around the globe are the most likely to be the starting point for WW3?

The rapid development of aircraft in the 1920’s and 1930’s far outpaced the development of aviation infrastructure to support them. Runways, even by the late 1930’s, were rare and often little more than an open grass field, useful only for the smallest and lightest of airplanes. It would be at least another decade until many cities developed suitable airports. But commercial aviation wasn’t going to wait around.

By the 1930’s large, luxurious flying boats were already carrying passengers to far-flung exotic destinations. Requiring only a reasonably calm stretch of water and minimal infrastructure, flying boats kick started an early era of air travel. Destinations that once took weeks to reach by boat could now be reached in just a matter of days. For the lucky few who could afford it, flying boats were simply the most luxurious way to travel. As they were generally larger and more capable than land-based aircraft, many were convinced that the future of long-range air travel belonged to large flying boats.

Antimatter is the opposite of normal matter. More specifically, the sub-atomic particles of antimatter have properties opposite those of normal matter. The electrical charge of those particles is reversed. Antimatter was created along with matter after the Big Bang, but antimatter is rare in today's universe, and scientists aren't sure why.

To better understand antimatter, one needs to know more about matter. Matter is made up of atoms, which are the basic units of chemical elements such as hydrogen, helium or oxygen. Each element has a certain number of atoms: Hydrogen has one atom; helium has two atoms; and so on.
