There are few certainties in science, but one fact of which we can all be certain is that one day we will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die We will die In five billion years our Sun will cease to shine Our planet will die in the searing heat, engulfed by the dying star. The atoms once known as you will be ejected out into space In billions of years they may become parts of new solar systems with their own stories to tell How does that make you feel? One day we will die One day we will die One day we will die One day we will die How does that make you feel? (we will die, we will die) How does that make you feel? How does that make you feel? But ultimately nothing will survive. It will all be gone In the far future there will come a time when time has no meaning as the Universe expands and fades Our descendants isolated on an island drifting in ocean of dark will watch as the galaxies evaporate away One day we will die One day we will die How does that make you feel? We will die We will die How does that make you feel? We will die (we will die, we will die) We will die How does that make you feel? We will die We will die How does that make you feel? The choice before us is not between immortality and eternal darkness The laws of nature have made that choice But we do get to choose how long we want to survive How long do you want the human race to survive? How does that make you feel? How does that make you feel? How long do you want the human race to survive?
