“In 5 billion years’ time, our star will be dying...By that time, Earth will be long gone, burnt to a crisp”

Hey, they can’t do that. It screws up all my plans!

[Red Badger]

And it won’t make a bit of difference whether you drove an SUV or a Prius, now will it?......................

[TruthInThoughtWordAndDeed]

NASA is all CGI all the time.

Long as it’s good the next 30 yrs....I’ll be 98!!!!

[backwoods-engineer]

I figure I have 25 good years left, before my mind or my body go. What the sun will do in a billion years or more is of no concern to me whatsoever.

Nor your kids ,grandkids and in my case Great grandkids!!!

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

https://en.wikipedia.org/wiki/Delta_Scorpii

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

“burnt to a crisp”
Now THAT’s global warming!

[equaviator]

Sadly, no. /s

And all this could be avoided if only we banned coal fired electricity plants and enacted cap and trade . . .

if we don’t start moving life off this rock and find some new rocks to live on

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

[Conan the Librarian]

Then we are doomed.

(Actually, I feel that as soon as someone figures out how to make money off of space travel, the exodus will begin and, even if we have to use generation ships, we’ll get off Earth)

[dfwgator]

Will the Earth eventually experience “White Flight”?

[PapaBear3625]

By that time, Earth will be long gone, burnt to a crisp as the sun dies.

In 5 billion years, either humans will no longer be here, or we will be able to move the Earth somewhere else.

[equaviator]

Every honky for himself!

[equaviator]

“to move the Earth somewhere else.”

Kinda like cheating at pinball and getting it right the first time.

Artificial gravity isn’t sci-fi, it’s an ancient principle. Tie a bucket onto a rope and swing it around your head. Centripetal force isn’t new. Just have to make the rotating piece big enough in diameter to keep the angular velocity down and keep people from getting motion sickness.

Thanks Red Badger.
