Comic book character created by Gardner Fox and Harry Lampert, the Flash is a superhero who has a velocity superhuman. Looking at videos of series and movies with the character, physicist Rhett Allan estimated that the hero's speed should be something around 1100 km/h, or approximately 305.5 m/s. In some episodes of movies or comics, Flash has already reached speeds much higher than that of light.
In addition to running at incredible speed, the hero can create vacuum, take superspeed readings, support telepathic controls, create clones, climbing walls and walking on water.
Super speed effects
Countless physical effects would occur in an individual who reached speeds as high as those reached by the superhero. The following are five facts that would be possible if someone could run like Flash.
1. It would be able to throw punches as powerful as nuclear warheads!
Assuming that Flash can assume speeds even greater than that of light, which is physically impossible, its blows could dissipate much more energy than
atomic bombs. THE Theory of relativity restricted, of Albert Einstein, demonstrates that the energy of a body varies according to its mass and speed, so the higher the speed, the more kinetic energy will be accumulated by the body.If your speed reaches 98% of speed of light, about 294 million meters per second, with just the weight of his fist, Flash would accumulate an energy of 50 megatons, which is equivalent to that of the Tsar Bomb, most powerful nuclear warhead ever detonated.
Tsar Bomb was the name given to the hydrogen bomb manufactured by the Soviet Union and tested on October 30, 1961
2. It would rip the limbs off the victims it was going to save
You wouldn't want to be saved by Flash! Due to its extremely high speed, if the hero ran past and grabbed the arm of a person in danger, he would tear the victim's limb off. The high speed and the inertia of the object would cause the limbs touched by the hero to be ripped off immediately!
3. I would always be barefoot
THE frictional force between our feet and the ground is what allows us to walk. When pushing the floor backwards, the friction force established between the shoe and the floor propels itUS forward. When running at such high speeds, the friction between the ground and your feet would practically disintegrate the incredible Flash's red boots.
4. would get off the planet easily
Running at such high speeds, Flash would easily hit the escape velocity, minimum speed required for a body to leave a planet. Earth's escape velocity is somewhere around 40,000 km/h. If he ran in any direction with a speed equal to or greater than that, the hero would go into space.
To leave Earth, a rocket needs a speed of 40,000 km/h
5. travel through time
Reaching speeds close to that of light, the hero would suffer the effects of temporal dilation, provided for in Einstein's Special Theory of Relativity. Objects that are at very high speeds mark shorter time intervals than objects at rest.
Moving at high speeds causes changes in the notion of time
If Flash ran at 99% the speed of light, a year of running for him would correspond to seven years for someone who was stationary. Upon reaching rest, the hero would be seven years in the future!
