You're reading these words right now.
We can say that even though we don't know when you'll read this. We can't say you read them yesterday, or will read them tomorrow, but we say that right now, you're reading the word "now."That's how special "now" is. And yet, for all the thought that's been devoted to time, science doesn't consider "now" as different from the future or the past. Don't take our word for it — Albert Einstein himself struggled with this conundrum.
