Actually, we had better HOPE they are right. We actually know relatively little about how stars work.

We don’t know if the Sun will stay stable 5 billion years or 5 more seconds.

We can take good guesses, compare to other similar stars, and hope, but, if we don’t start moving life off this rock and find some new rocks to live on, the show is over.

Sounds negative, yes, but, stars don’t always play by the rules, and we are totally dependent on the one we have.

Read about this star: Delta Scorpius

It was thought to be a nice stable star until 2000.

Without artificial gravity of some type and a propulsion system that reaches speeds in the 100,000 mi/sec range, we are going nowhere. Currently artificial gravity is sci fi and top velocity is 10 mi/sec. But with billions of years, we have time. lol

Will the Earth eventually experience “White Flight”?

We don’t know if the Sun will stay stable 5 billion years or 5 more seconds.

It will never take less than 8 seconds. Guaranteed!

That's how long its light takes to get to us.
We would never know what hit us.

That's why it is not even on my long list of things to waste time about.
