Time’s reality is questioned by both Einstein’s relativity and McTaggart’s logical arguments, which present different but inconclusive methods to understand time.

Modern physics suggests time may be an illusion. Einstein’s theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time simultaneously – with no special “now.”

What’s the future to one observer, is the past to another. That means time doesn’t flow from past to future, as we experience it.

This clashes with how time is conceptualized in other areas of physics, such as quantum mechanics, however. So is time an illusion or not? One approach to find out would be to try to prove that time is unreal using logic alone.
