    Don’t worry about the sun expanding to swallow earth! It will gradually get hotter as the core uses fuel and contracts, rendering earth uninhabitable within just 1b years (if we don’t beat it to the punch)

      The Earth is about 4.5 billion years old and the Sun will expand large enough to make the planet uninhabitable in about 500 million years.

      In other words, the Earth is already 90% of the way through its life cycle.

      Don’t worry though. We’ll almost certainly make it uninhabitable for humans long, long before that time
