This is it folks: the much predicted, always feared, occasionally delicious end of the universe.
No, we don't mean that whole incredibly-depressing-ice-cap-melting thing from yesterday. We mean the genuine end of all things, as visualised in this pretty impressive and far-sighted video.
The clip takes our current best guesses for how long various elements of our lives will last - including how much fuel the Sun has left, how long our space-faring descendants will last in deep space, and eventually what will happen to the universe itself. Then it shows all of these horrible things happening at once, in rapid and utterly awful succession.
Just as prior internet visualisations have taught us how small we really are - and how far away Mars really is - this one achieves the dubious glory of pointing out in excruciating clarity how likely it is that everything will just end in silence, heat death and nothingness.
Update: a previous version of this story used the phrase "space faring ancestors" instead of "descendants". While we do not rule out the possibility of a dual pan-temporal warp tunnel making it possible to arrive back home after a 6,000 light year round-trip before you arrived, time machines do not currently exist. So we fixed the typo.
