Have you ever wondered if time is real or just an illusion? Philosophers and scientists have debated this question for centuries. On one hand, time feels incredibly real. We measure it, structure our lives around it, and experience it in a linear fashion—past, present, future. But some philosophers, like Immanuel Kant, believed time might not be something out there in the world. Instead, it could be a construct of the human mind, a way for us to understand our experiences.
