 As living things, everything we do is in some way influenced by time. Scientists continue to debate whether the idea is real or an illusion because it is so difficult to understand.

Astrophysicist Michelle Thaller, science communicator Bill Nye, writer James Gleick, and neuroscientist Dean Buonomano explore the perception of time by the human brain, the idea that time is a fourth dimension in theoretical physics, and the idea that space and time are intertwined in this video.

The experts discuss perception, definition, and experience, with Thaller illuminating Einstein's theory of relativity and Buonomano outlining eternalism.
