Future Earth cityscape. Computer artwork of how the Earth may appear 500 million years from now. By this time the Sun will have grown considerably hotter due to its natural evolution as a type G5V star, making the Earth a hotter place to live. While it is unlikely that beings that look or think anything like us would still populate the Earth 500 million years from now, if we were still here in our present form, we would likely find the Earth very inhospitable. This image represents an Earth buried by layers of cities built by a hundred million generations of our descendants.
