Think About It XIX

Is yesterday tomorrow today?

 

Does time exist independently

of human consciousness?

 

Were you to board a spaceship,

 head out from earth at 99.999999 percent of light speed,

 travel for six months and then head back home at the same speed,

 your motion would slow your clock

 relative to those that remain stationary on Earth,

 so that you’d be one year older upon your return,

 while everyone on Earth would have aged about 7,000 years.

 

Brian Greene
