Time dilation, a captivating concept embedded in Einstein’s theory of relativity, has been experimentally validated on Earth.

The effect of time dilation due to gravity has been measured to the smallest scale yet. Predicted by Einstein’s theory of general relativity, this has been measured using stars, supermassive black ...

Google says spyware was slipped onto smartphones in Italy and Kazakhstan with the help of mobile interent service providers who cut off service so users could be ...

Black holes are one of the universe’s most enigmatic phenomena. They defy our understanding of physics, challenging our ...

There are a million theories about the human species and how we interact with the earth. Quantum physics is the study of matter and energy. It discovers what the building blocks of nature are. Many ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Black holes are not just "monsters that devour everything"; they also cause strange changes in time itself. According to ...

Last week, we touched upon E=mc2, and how Einstein’s theory of relativity turned the world of physics upside-down. Now, we’re using that theory to show why the very concept of time may not be what you ...

Since I didn't want to hijack the Stephen Hawking on black holes thread, I wanted to ask in a separate topic. So matter falls into a black hole, as it gets closer and closer, the falling objects seem ...

Einstein tells us that the time you experience between two events depends on the path you take through the universe. In particular, it can depend on the curvature of spacetime along your trajectory.
