The Science of Superman
Here is how I believe Superman got his powers.
Superman’s skin is like a plant’s (metaphorically speaking), when the solar energy of a yellow sun hit’s his skin, he grows, but instead of growing larger, he grows stronger, his cell’s evolve, his bones become denser, his muscles become stronger, and his senses become more acute. Over the span of 21 years he became god-like, able to hear whispers from space, smell anything from hundreds of miles away, to lift massive objects without fidgeting or trying in the least bit, hold his breath for hours, and even breathe ice.
When light hits Superman, it absorbs solar energy from his skin cells, charging it, which generates a bio-aura of charged light particles. When light particles hit his eye he can see them, and since sight is the strongest sense in the body, he can focus his entire bio-aura into his eyes, and charge it, and even focus it into a burning beam of charged light particles.
By using his laser vision, he can spin beams of light particles so fast that they collapse space time and create an indent in the fabric of space itself, generating gravity, causing him to fall into the indent, this gives him the ability to fly, and accelerate to speeds faster than light.
Feel free to criticize my theories as much as you wish. 🙂
