Your navigator lives in the future
GPS satellites are located further from Earth where gravity is weaker, and they move at high speeds. Because of this, their onboard clocks run 38 microseconds faster per day compared to clocks on the planet's surface.
Engineers must constantly correct the time in orbit so that maps on your smartphone show the right path. We use the results of spacetime curvature every time we order a taxi.

Without accounting for the theory of relativity, Google Maps would be off by 10 kilometers within a day.

Spotlight effect
Students were forced to wear a ridiculous singer t-shirt. Participants were sure half the audience stared at them, but real figures showed: the portrait was noticed by only two out of ten. We think everyone watches us. 👕👀🙈

Map of the Invisible Skeleton
Scientists managed to look billions of light-years away and record dark matter for the first time thanks to the effect of light bending from distant galaxies by massive objects.
