The Cuban Revolution (1952-58)

The 60s were a turbulent time period for the United States. This was the heyday of the Cold War and the US had serious concerns about the communist government that had been established off its southern shores in Cuba (the Bay of Pigs incident, the Cuba missile crisis, and economic sanctions were all a result of this tension). The communist (actually, it is socialist) government of Cuba, led by Fidel Castro had its beginnings

Iranian Revolution (1978-79)

The Middle East has always been a hotbed for revolution. Iran, a consistent focus of international attention in recent years, was also headline news in the 70s. During the majority part of the 60s and 70s, Iran was ruled by Mohammad Reza Shah Pahlavi. The Shah (or ‘the king’) initiated a sweeping set of reforms in the early 60s (Ironically, called the White Revolution) that severely limited traditional religious authority and influence in the nation. As a result of the Shah’s more secular leanings, the US lent its financial support to the regime

Multiverse

Imagine not just one, but numerous universes, all existing at the same time. The multiverse (or meta-universe) is the hypothetical set of multiple possible universes (including the historical universe we consistently experience) that together comprise everything that exists and can exist: the entirety of space, time, matter, and energy as well as the physical laws and constants that describe them. But then again, there is no proof of a multiverse, so maybe our own universe is the biggest after all.

Our Universe

Estimate: 156 Billion Ly

A picture paints a thousand words, so just look at this poster and try to imagine/comprehend how big our universe is. The mind boggling figures are written below. Here is a link to the full sized image.
Earth 1.27×104 km

Sun 1.39×106 km
Solar System 2.99×1010 km or 0.0032 Ly
Solar interstellar 6.17×1014 km or 65 Ly

Biggest galaxy cluster

El Gordo is located over seven billion light years from Earth, meaning that it is being observed at a young age. According to the scientists involved in this study, this cluster of galaxies is the most massive, the hottest, and gives off the most X-rays of any known cluster at this distance or beyond.

The Milky Way

100,000-120,000 light-years in diameter - The Milky Way is a barred spiral galaxy 100,000-120,000 light-years in diameter containing 200-400 billion stars. It may contain at least as many planets, with an estimated 10 billion of those orbiting in the habitable zone of their parent stars.

Extreme big supermassive blackholes

21 billion sun masses - A supermassive black hole is the largest type of black hole in a galaxy, on the order of hundreds of thousands to billions of solar masses. Most, and possibly all galaxies, including the Milky Way, are believed to contain supermassive black holes at their centers. One of these newly surveyed monsters, which weighs as much as 21 billion Suns, is in an egg-shaped swirl of stars known as NGC 4889, the brightest galaxy in a sprawling cloud of thousands of galaxies about 336 million light-years away in the Coma constellation. This black hole is so big, our entire solar system would fit in about a dozen times.
