We can afford to waste most things, but not time.

The most profound property of time is that nothing lasts forever. At the same time, time itself is probably eternal. Now, isn’t that a paradox to ponder over?

What started time? And how much time did that unknown phenomenon take to start time?

I guess my cognitive abilities and withering brain plasticity cannot grasp the placement of time as a dimension in an equally difficult-to-grasp theory of relativity.

The flow of time stops for no one. Once a moment passes, you cannot go back and change it. Not with science, not with divine interventions.

Photons that travel at the speed of light must have no concept of time.
