If humans could see with X-rays instead of visible light, our perception of the world and each other would be significantly different. X-rays have much shorter wavelengths and higher energy compared to visible light, allowing them to pass through soft tissues but being absorbed by denser materials like bones.
If X-rays were our natural mode of vision, we would be able to see through most objects that are currently opaque to our eyes. This would include seeing through human bodies and perceiving the internal structures such as bones, organs, and other dense tissues. In essence, we would be able to see the skeletal structure of living beings, including ourselves.
However, it's important to note that X-ray vision, as portrayed in popular media, often simplifies the complexity of X-ray imaging. In reality, the interpretation of X-ray images requires specialized equipment and expertise to properly distinguish and interpret the internal structures. Additionally, excessive exposure to X-rays can be harmful, so the ability to naturally perceive X-rays would require additional biological adaptations to protect our tissues from radiation damage.
In summary, if we could see with X-rays, we would indeed perceive each other as skeletons due to the higher absorption of X-rays by bones. However, it's crucial to understand that X-ray vision would bring significant changes to our perception and would require adaptations to ensure safety and proper interpretation of the X-ray information.
