Is time real or is it an illusion? | Michelle Thaller | Big Think
Big Think・5 minutes read
Physicists discuss how time can vary based on speed according to Einstein's theory, with the ultimate limit being the speed of light at which time ceases to progress. Practical applications like global positioning satellites require adjustments for time dilation due to high speeds, supporting Einstein's idea that space and time are interconnected, implying all moments in time are equally real.
Insights
- Time is not a constant but varies based on speed according to Einstein's theory of relativity, with the speed of light marking the point where time ceases to progress.
- Einstein's theory of space-time asserts that space and time are interconnected, implying that the movement through space can influence the passage of time, indicating the simultaneous reality of all points in time.
