How to Make the Planet Sustain Life for Longer

Astronomers have known for a long time that the Sun is currently at the middle of its life cycle, having already burnt for more than 4.6 billion years. As a yellow main sequence star, it is expected to live a full life of about 10 billion years, but naturally, during this time, it will evolve. Sadly for Earth, this implies it expanding as it turns into a red supergiant, eventually engulfing the entire planet within its mass. Things are considered to start getting pretty worse in about one billion years, when astronomers believe the heat will be so great that our planet will become uninhabitable.

However, this theory has recently been contested by a group of experts from the California Institute of Technology (Caltech), who say that we could make the planet able to support life even beyond the 1 billion years marker currently theorized. But, in order to do that, we’d have to get into some pretty serious geoengineering schemes. Read more
