What do we say that time is an illusion

Question

Some article talking about that: [https://www.nature.com/articles/d41586-018-04558-7#:~:text=According%20to%20theoretical%20physicist%20Carlo,of%20a%20universally%20ticking%20clock](https://www.nature.com/articles/d41586-018-04558-7#:~:text=According%20to%20theoretical%20physicist%20Carlo,of%20a%20universally%20ticking%20clock).

I really don’t understand how time can be an illusion. I mean that I know that what I’ve done before is done and I can’t change it.

So how can we say that time is an illusion?

​

thanks

Answer 1

The article is saying that the *flow* of time is an illusion.

Saying “I’m moving from my childhood into my old age” is like saying “Interstate 80 is moving from San Francisco to New York”. Interstate 80 is not actually moving, it just happens to be extended across multiple locations, such that it exists in both San Francisco and New York. Likewise, you’re extended across multiple times, such that you exist in both your childhood and your old age.
