A previous video from RealLifeLore explored what will happen to our home in the universe over the next billion years. But a billion years is hardly the end of time, as is proven in this video about the next 100 trillion years of the universe. As anyone with a passing knowledge of astrophysics knows, this is all ending in the heat death of the universe–every star burning out until the universe is just an infinite dark space. But before then, there are a lot of possibilities.

In one billion years, due to the increased luminosity of the sun. Earth will be basically uninhabitable by humans, though microbes and some animals may survive in the scorched planet’s remaining water supplies. Eventually though, Earth will resemble Venus today–a hellish world of extreme high temperatures where nothing can survive. As the sun’s luminosity continues to increase, there are other possibilities for life on planets like Mars and even Saturn’s moon Titan. But in 8 billion years, the sun will collapse into a white dwarf, taking away our solar system’s source of heat and energy and leaving it a barren wasteland. By that point, universal expansion will put almost everything besides our local cluster of universes outside of what is observable to us anyway.
From then on out, things get pretty bleak, as the stars of the universe slowly burn out. So don’t spend too much time worrying about potential nuclear war–just wait long enough, and the whole universe will snuff itself out.
