We non-physics mortals have a concept of time that is different from what science tells us. We talk about, now, later, the past, i.e., time passes and we divide it into past, present and future.

Theoretical physicist Sabine Hossenfelder describes "what's ahead" in her video titled "Does the Past Still Exist?" About the perceived passing of time, she writes "But what physics tells us about time is very different from our perception. The person who figured this out was none other than Albert Einstein. I know. That guy again. Turns out he kind of knew it all. What did Einstein teach us about the past, the present, and the future? That’s what we’ll talk about today."
