Superman's powers, including his strength and energy absorption abilities, are fictional and do not adhere to the laws of physics as we understand them. Superman is a character from comic books and movies, and his abilities are a product of creative storytelling rather than scientific principles.
In the Superman mythos, his strength is often attributed to the effects of Earth's yellow sun, which provides him with extraordinary powers due to its radiation. The explanation goes that Superman's body absorbs and stores solar energy, granting him superhuman strength and abilities. However, it's important to remember that this is purely fictional and not scientifically plausible.
In reality, the amount of energy available in the universe is finite, and stars have their own limits regarding the energy they emit. No individual, fictional or otherwise, can possess infinite strength or harness more energy than the total available in the universe. These concepts are beyond the scope of our current understanding of physics.
Superman's abilities are part of a fictional narrative that aims to entertain and engage audiences. While they may defy scientific principles, they allow for exciting and imaginative storytelling within the context of superhero fiction. It's important to differentiate between fictional concepts and scientific reality when discussing such characters and their abilities.
