A newbie’s information to time journey

Everybody can journey in time (opens in new tab). You do it whether or not you wish to or not, at a gentle price of 1 second per second. Chances are you’ll suppose there is no similarity to touring in one of many three spatial dimensions at, say, one foot per second. However based on Einstein (opens in new tab)‘s principle of relativity (opens in new tab), we dwell in a four-dimensional continuum — space-time — during which area and time are interchangeable.

Einstein discovered that the quicker you progress by area, the slower you progress by time — you age extra slowly, in different phrases. One of many key concepts in relativity is that nothing can journey quicker than the pace of sunshine (opens in new tab) — about 186,000 miles per second (300,000 kilometers per second), or one light-year per yr). However you will get very near it. If a spaceship had been to fly at 99% of the pace of sunshine, you’d see it journey a light-year of distance in simply over a yr of time.
