Wells' classic novel sets up the idea of a distopia, the exact opposite of a utopia. He used evolution as a way to exaggerate the problems he saw facing society in his day. Evolution is essential for life, so it also goes hand in hand with Astrobiology. Another important point brought up in this book is the lifespan of stars. Stars provide the energy needed for life, so they too must be considered in this subject.

When the Time Traveller first leapt through time, he discovered that almost one million years had passed. Humans had changed drastically during this time. The upper class, who lived on the surface and never participated in any physical labor, evolved into the frail beings known as the Eloi. The lower class, forced to move underground and forced to do labor, regressed into the primal Morlocks. This is a perfect example of how evolution can work. Evolution is a very slow process, requiring hundreds of thousands of years before a significant change is noticeable. It has taken millions of years for humans to become homo-sapiens. In one million years, humans will have evolved even further. If we were to rely more on technology to do work for us, there is definitely a possibility that we will become frail creatures.

Near the end of the book, the Time Traveller once again journeys into the future. This time, the machine comes to a stop a few billion years into the future. What he discovers is that the Sun has changed from a yellow disk in the sky to a gigantic red behemoth. The only life that appeared to still exist was giant crab monsters. What the Time Traveller was witnessing is the death of a star. The star we orbit around is a G-star, giving it a lifespan of about 10 billion years. Our Sun gives off light by fusing hydrogen molecules into helium. In about 5 billion years, it will run out of hydrogen in its core, and will begin its death phase. The Sun will swell up drastically in size, and will become red in color. The temperature on Earth during this time will be around 700 degrees Celsius, making it impossible for any life to still exist. Finally, the outer layers of the Sun will be expelled, destroying much in its path. Of course, this is still a long ways away. By that time we will hopefully have found a new world to live on.
