What are the four hypothesis the time traveler makes in the year 802 701?

In H.G. Wells' "The Time Machine," the time traveler hypothesizes that human society has evolved into two distinct species: the Eloi, who are gentle and childlike, and the Morlocks, who are subterranean and predatory. He speculates that the division between the two reflects the consequences of class division and industrialization in his own time. Additionally, he wonders about the future of humanity, pondering the effects of environmental changes and technological advancements on evolution. Lastly, he considers the implications of time travel itself, questioning the nature of time and its impact on civilization.
