does a fictional character that travels at the speed of light have mass?

Answer 1

According to current scientific understanding, any object or particle with mass cannot achieve or travel at the speed of light, as it would require infinite energy to do so. Therefore, if a fictional character is depicted as traveling at the speed of light, it would mean that they are massless. This concept is often explored in science fiction, where characters with superpowers or advanced technology can defy the laws of physics. However, it is important to note that this depiction goes against our current understanding of the universe.
