The nature of 'death' - fearing it, like anything, is irrational

Time destroys everything its path.

The universe is vast, time is eternal. Existence is infinite, that encompasses our own universe, that which is outside it, everything.

All space, all time. Life, biological life as we know it, probably happens in billions of locations through and outwith the known cosmos, and billions of times and points in time.

This is probably not the first time you have been a conscious being. It is not the last. Time is infinite. We never stop experiencing life, regardless of how long the death is in between. When you die, you will return to what you were before you were conceived to this existence. Just as you were conceived now, you have been, and will be an infinite number of times into eternity.

That is the nature of the universe, that is the nature of life, the nature of death. It is as certain as the stars.
