I'm going to move this sun to a nicer area.

Is this nibiru again?

BTW my m8 who reckons Nibiru is true still reckons it is coming! Apparently its passing behind the sun now.....

Wouldn't it be easier just to move themselves to another star, rather than try shifting the star itself (and all its planets)?

Anyway, advanced aliens wouldn't be round one star long enough to worry about any impending danger, to themselves at any rate.

They'd probably be nomads hopping between interesting looking solar systems (and spending the vast majority of time asleep en voyage, hence the reason their presence isn't obvious to distant observers).

There is just so much wrong with that article. Was it an old April 1st?
Building a mega-machine capable of moving stars by destroying 'one small planet'?

Even super duper advanced aliens would be bound by the laws of physics (assuming they're right?), interstellar travel isn't ever going to be a walk in the park and only a very few systems would be suitable anyway.

Maybe shifting stars is the easy option?

Given a long enough timespan the planet-x theory is probably going to happen at some point.

Interstellar travel will be a walk in the park, provided the travellers are willing to sacrifice time, and that's just using starships or conventional mass transfer in some form.

If they are able to send entangled particles to destinations in advance, along with a suitable reconstruction kit, they could materialise instantly at those destinations, at the cost of consuming some entanglement. (Did a quick search, and the SF novel Entanglement looks intriguing, but the concept is anything but fictional.)

Also, this isn't really about science, but is more a political and psychological issue. Firstly in coming centuries there will probably be more and more old people, who the young will have an increasing incentive to send packing if only to give themselves room. But also, longer term, when all basic physical laws have long since been sussed to the limit of experimental verification, I reckon humanity will realise that hanging around in our solar system will need to inevitable stagnation, and everyone will set off to explore and nurture nature's variety (after making a start on this by returning Earth to its natural pre-human condition).
