Eloi world. The Time Traveller’s first stop in the remote future. Although it occupies the same space as the Time Traveller’s home, the world of the Eloi is separated from it by some 800,000 years. That fact alone expresses Wells’s primary Darwinian purpose: to demonstrate that evolution will continue beyond the world he and his readers know. This setting is, at first, a pastoral idyll, a place of green fields, strange flowers, and a curious innocence. Soon, however, a different impression is created, as the Time Traveller notices the decaying buildings, the sense of things running down, and in particular the sense that the inhabitants of this world, the Eloi, are, though pretty and innocent, also in decline. This is emphasized in his visit to the Palace of Green Porcelain, once a great museum though now most of its exhibits have rotted away; the age of human achievement is long passed.
Morlock world. Though visited only once and very briefly, the underground realm of the Morlocks forms a constant counterpoint to the pastoral simplicity of the world of the Eloi. It is a lightless world, a world of dark oppression, and the Morlocks are as much its victims as anyone else. There is a sense of machinery, though the reader never encounters it directly.
Beach. After finally escaping the world of the Eloi and the Morlocks, the Time Traveller flees to a point in the far distant future when the world is coming to an end. In one of the most effective and influential scenes in the whole of science fiction, he describes a tideless sea and desolate shore, all bathed in the dim, red light of a huge and unmoving Sun. Far out across the water one lone, dark shape flops hopelessly. Given the scientific knowledge of Wells’s time, it is an accurate portrait of one possible end-of-the-world scenario–with the Moon gone, the Sun’s energy failing, Earth pulled from its orbit and losing its rotation, with only the steady approach to the dying sun preventing it being a completely frozen waste. It is also an effective metaphor for the message of evolution: All this must pass.
