Superman's powers and abilities are scientifically possible.

Contrary to your belief, Superman's powers are not scientifically possible.Flight:The science of flight is known as aerodynamics. There are four forces that govern flight-- lift, weight, thrust, and drag. [1]Lift is the force that allows birds, insects, bats, and planes to take to the air. It is governed by the air flowing over wings. [2]Unfortunately for Superman, he had no wings. The basic principles of aerodynamics dictate that Superman would be incapable of unaided flight with his anthropomorphic form.To this, you may point out that flight does sometimes exist without wings (e.g. hot air balloons). But a close examination of the science will show that this phenomenon also cannot be used to explain Superman's ability to fly. Buoyancy is the scientific principle at work here, and it involves the difference between the density of the floating object and the density of the medium. [3]In Superman's case, it would be impossible for him to have a lighter density than that of the Earth's atmosphere (which is primarily composed of nitrogen). Simply put, the two scientific principles that can be used to explain flight in the Earth's atmosphere cannot be used to explain Superman's flight. Superman's ability to fly is scientifically impossible. Heat vision:Some creatures have evolved that are able to create their own light [4]. But bioluminescence cannot possibly explain Superman's heat vision. I know of no animals that emit light from their eyes. Furthermore, even if a bioluminescent eye did evolve, the eye is far too delicate to have that light be emitted as an intense heat beam [5]. Such an ability would most certainly cause irreparable damage to the eye as soon as it is used.Due to the science of vision, the eye must be delicate enough to allow enough light through for proper vision. It cannot simultaneously be made strong enough to withstand an intense beam of heat. The same organ cannot be used for both functions. If heat emission were possible and did evolve, it would not be emitted from the eyes. The very nature of the eye's places a limit on their strength, and that limit is certainly too low to withstand Superman's heat beam shooting out of them. Super speed:Superman's super speed on his two legs would not be possible. Looking at the list of the fastest animals [6], it is clear that really fast speeds are produced by quadrupeds. Although there are a few humans that can run at very fast speeds, even in these cases such speeds can only be maintained for a short period of time.Furthermore, a detailed study on the speeds of various mammals concludes that the top possible speed for a human is 40 mph [7]. This speed does not qualify as super speed. Furthermore, no one has ever been recorded even going 30 mph [8]. The fastest recorded human footspeed is slightly less than 28 mph. The theoretical limit is 40 mph. From this, it must be concluded that Superman's super speed is scientifically impossible. Looking at the science behind Superman's powers and abilities, it becomes pretty clear that Superman's powers and abilities are not scientifically possible.[1] http://web.mit.edu...
