How Captain America became a super hero

 The popular comic book character and movie icon Captain America has shown awesome powers in its adventures for decades. But can this extraordinary powers of this superhero truly exist? Marvel Comics has been publishing monthly American comic books since 1939, featuring well-known characters such as the Incredible Hulk, the Mighty Thor, the Invincible Iron Man, and Captain America. These illustrated adventures are special because most of the fictional characters operate in a single reality known as the Marvel Universe. In this universe, heroes are organized into powerful teams such as the Avengers.Captain America does not have super rare powers or characteristics as other marvel super heroes, but he is at the absolute peak of possible human performance. Steve Rogers a frail young man too fragile for the front line, but with a sense of duty, who volunteered for a top secret military experiment. the experimento consisted in the injection of a " super-soldier serum" . Rogers was introduced in a capsule and was chemically transformed into broad-shouldered soldier with extraordinary strength and endurance by introducing him a Super-Soldier Serum.

But lets talk about what exactly can this Super-Soldier Serum have? Although our bodies naturally produce testosterone, the hormone responsible for muscle mass and strength, a faster-acting version of the steroid would be needed for the rapid transformation of Steve Rogers. Notably, synthetic anabolic steroids like testosterone were used to facilitate the growth of skeletal muscle as far back as the 1930s. Growth hormones may be another Super-Soldier Serum component. Their excess production during childhood results in gigantism. Like the fictional Steve Rogers, the Austrian Adam Rainer, born in 1899, attempted to join the Army as a teenager during World War I, but was rejected due to his short 4'6" stature and generally weak body. Without Captain America's laboratory procedure, Rainer grew to a height of 7'1" by the time he was 31 years old. This was caused by an overproduction of growth hormones from a tumor pressing on his pituitary gland. Vibranium, the fictional material of the shield of Captain America, is said to be of extraterrestrial origin. Meteorite components were part of the studded gold medals awarded to athletic heroes at the 2014 Winter Olympics in Sochi in honor of the one-year anniversary of the extraterrestrial strike that damaged the Russian city of Chelyabinsk. However, the primary component of this "chondrite" meteorite is iron.Shields have been made from iron since antiquity, but modern thinking in the chemistry of shield making has turned further back in time to 24,000 B.C. when the crafting of ceramics began. Still not quite as light and resilient as the fictional vibranium, today’s ceramic shielding from materials, such as aluminum oxide, silicon nitride, boron carbide, titanium diboride, and tungsten carbide, can weigh 50 % less than traditional steel, be nearly as hard as diamond, and capable of deflecting and absorbing energy from impact.

As children we always dream of being able to have some kind of super power or even to be super hero. Although these superheroes have some characteristics that can make them real, it is very difficult for them to exist. A world with this type of super heros would change many things for both good and bad, that is why having super heroes in the real world could become a problem in the future
