There are currently 31 GPS satellites in orbit around the earth helping us find our way to grandma's house, to the new trendy bar, and our very own home. Most people don't realize that those satellites are actually traveling in time, well on a micro level. Time is relevant depending on the closer and farther you get away from a gravitational force. Those orbiting satellites are actually off by 3,000,000,000th of a second every single day do to their distance from the earth and need to be calibrated accordingly to make sure the time is constantly correct. If they weren't constantly reconfigured you would be 6 miles off from your grandmas house.

Everyone knows Einsteins equation E=mc2 and that Energy= mass times speed of light squared. Well it's hard to consider that that equation means that light has mass. If you take into consideration the surface area of the earth being hit by sunlight and the energy of that light from the sun it means that there is 6 pounds of weight pushing on the earth at every single second.
