How it was 2 billion years ago, is the question.
And perhaps how it was 120 million years ago.
5 billion kg of fusion hydrogen per second... Holly s... it would be more than the estimated solar power the sun produced. Such energy in nuclear fusion, in 1 second, it's the humanity take in 1000 years.
I think the nuclear fusion energy in a second it's way more high than the ligh solar energy sun produces in 1 second. Maybe a lot of zeros in right side of the number.

The important question isn't how long will the sun last, but rather how long will it radiate energy hospitable to human life.
