At some point in this episode you mention the Sun becoming to hot for life on Earth in just 50 million years from today.

All references I found about this put that point at 1 billion years from now
(Sun becoming 10% hotter every billion years, which will make Earth's oceans boil away in about 1 billion years)

So where does this 50 million years threshold come from?
