Brain-In-Vat Thought Experiment

The Brain-In-Vat thought experiment questions whether our perceptions truly reflect reality. Imagine a brain kept alive in a vat, connected to a computer that simulates experiences indistinguishable from real life. If this brain receives realistic signals, it would have perceptions, thoughts, and feelings as if it were in the real world. The experiment explores whether we can be certain about what is genuinely real or if our perceptions could be just artificial illusions. Essentially, it challenges us to consider whether our senses and experiences can reliably prove the nature of reality.
