We all know that in the distant future, the year 2000, robotic beings will rule the world. But what about the future after that? Well, that’s where the above timeline from the BBC comes in. 5.4 billion years from now, for instance, the Sun will run out of fuel. 110 trillion years from now, all stars will run out of fuel. 100 quintillion years from now, the Earth — if it hasn’t been destroyed already — will have decayed enough to be swallowed up by the Sun (in whatever diminished state it takes at that point).
