Relativistic Interval

• Meaning of space-like, time-like, light-like✅
  • There seems to be something about the inside and outside of the light cone, but I don’t really understand it.
  • If we think in terms of intervals, the meaning becomes clear (blu3mo)(blu3mo)(blu3mo)
    • Basically, it’s about whether the slope is greater than or less than 1. If it’s completely vertical, it’s a time interval, and if it’s completely horizontal, it’s a space interval.
      • If we rearrange the equation, it becomes dt/dx > 1.
      • If we consider the transformation of time dilation/length contraction, a time-like interval becomes a time interval, and a space-like interval becomes a space interval.
    • It makes sense that the intervals of time and space coincide with light, of course.
