Albert Einstein predicted it and Mars has now confirmed it: time flows differently on the Red Planet, forcing future missions to adapt

This feels crazy!

Essentially time is a construct that we came up with, and while it mostly works, consider that we have to add in time periodically (hence the leap year), and because of the constraints on it, "time travel" as we think of it is impossible.  It's a linear function within the construct.

But Einstein used the theory of relativity to help us think about the construct and how it might not apply in every situation, because of orbits around the sun, gravity, and other factors. 

And we're seeing that this is the case on mars. Time is not absolute, and what we think of in that sense does not apply on mars (or really anywhere else).

So that means when you're "late for work ," you really aren't because time itself doesn't make sense. (Ha) 

And in science fiction when they talk about traveling through time by somehow warping space-time, they're actually applying science.

It kind of blows my mind.
