More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together. Einstein also said our universe has a speed limit: nothing can travel faster than the speed of light (186,000 miles per second). What does this mean for time ...
We can't use a time machine to travel hundreds of years into the past or future. That kind of time travel only happens in books and movies. But the math of time travel doesaffect the things we use every day. For example, we use GPS satellites to help us figure out how to get to new places. (Check out our video about how GPS satellites work.) NASA s...
Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
Learn how Einstein's theory of relativity explains how time and space are linked and how they affect clocks on airplanes, satellites and GPS. Find out why we can't travel back in time, but we can use time-travel calculations in everyday life.
Apr 26, 2023 · Time traveling to the near future is easy: you’re doing it right now at a rate of one second per second, and physicists say that rate can change. According to Einstein’s special theory of...
Jun 13, 2022 · The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of ...
Oct 23, 2016 · A book review of James Gleick's exploration of the idea of time travel in science and culture, from H.G. Wells to Stephen Hawking. Learn how time travel exerts an irresistible pull on our imagination, and why we wish it were possible.
