Every time you drive and use Google Maps to make a right turn or use GPS to tell a friend where you are, Albert Einstein’s two laws of relativity are invoked. This is the reason. GPS (Global Positioning System) relies on satellites orbiting at high speeds approximately 20,000 kilometers above the Earth. Clocks on these … Read more

Researchers have detected for the first time that voids in the sky are moving faster than people. speed of light And they broke the speed limit of the universe without breaking the theory of relativity. Recent studies have shown void acceleration. The researchers used recent advances in ultrafast electron microscopy to measure the voids of … Read more
