Astronomers know full well that the sun is very slowly getting brighter, and in a billion or so years time it will make Earth too hot to live on.
One scientist is now proposing a radical solution that will let humans live on this planet for longer – physically moving it away from the sun.
Albert Zijlstra, a professor of astrophysics at the University of Manchester, suggests shifting Earth further back from the sun by about three million miles.
At the moment, Earth is orbiting the sun at a distance of 93 million miles (150 million km) but this needs to extended to at least 96 million miles (155 million km), he says.
This movement would extend a year to 380 days, meaning we'd have to insert an extra 15 days into a calendar year somewhere.
'Earth will get warmer, and warmer – best estimates are that in one or two billion years, the oceans will begin to boil away,' Professor Zijlstra told MailOnline.
How would it work?
When a planet (such as Earth) slows down in its orbit, it moves closer to the sun. Likewise, when a planet speeds up in its orbit, it moves away from the sun.
Therefore, if we want to move Earth away from the sun, the objective is to speed up Earth.
Professor Zijlstra proposes doing this using a gravity assist or 'slingshot' manoeuvre, which are already used to speed up spacecraft after they've been launched from Earth.
It's a little-known fact that gravitational slingshots can also be used to reduce the speed of a spacecraft, which have the opposite effect on the planet - speeding it up.
Rather than a spacecraft - which would be too small - he proposes using a massive asteroid the size of a city.

When Worlds Collide?
Muy Estúpido
Stock up on long John’s for the ice age they create
And for God’s sake, get your covid shot
Great, another solution to a problem that doesn’t exist.
ROFL!
In that case, we could just use Upsidasium to move the Earth to a new orbit. After all, the world's entire supply is located in Miinesota.
Not wacky. Insane. Energy is not free. The energy required to do this is much more than humans have available to them. Dream on, “scientists”!
The idea is insane and irresponsible.
Instead of speeding up the earth, I want to slow it down.
So, I can get off.
“the sun is very slowly getting brighter, and in a billion or so years time it will make Earth too hot to live on. “
Oh no we’re all dead ... oh wait ... it said a billion years ... I thought it was a million years ... relax
Exactly right. The only solution is to move Earth to a different solar system.
—let’s straighten it out on its axisso we aren’t bothered by seasons and blow the moon up, so we have rigs like Saturn—both ideas of which came out of academia some years ago-
Believers in “global warming” are part of a messianic, doomsday cult. They are ready to kill us all just like the Aztecs ripped out victims’ hearts to feed their creepy, demon gods.
Albert Zijlstra - attention whore
It would be cheaper and simpler to move humans to Mars.
We’ll be needing all of those cows back for their combined reaction thrust.
You mean Mad Scientists
No. That's the point in speeding up which would raise the orbit just like satellites.
I do wonder what kind of chaos would ensue in the effect on the other planets, though.
While I applaud the effort to consider the kind of world we’ll leave behind for Keith Richards, isn’t there a balance between the centripetal forces of gravity and centrifugal forces of the orbit that have nothing to do with the earth’s rotation?
Albert Zijlstra seems to have a god complex.
