Could aliens harness stars to keep ahead of expanding universe?

Depending on which cosmological theory you subscribe to, the Universe will either continue to expand infinitely, cool off and die, OR, it will eventually stop expanding, begin to collapse and everything will die, and will start anew.

Either way, it will kill you..................

This would make for some interesting Science Fiction.

If you have the technology to capture and transport a star, then you have the technology to produce all the energy you want anyway.

Aliens might be able to do it, but liberals would never go for us doing it.

[Red Badger]

Been done.

Contact............The book. The movie sucked. Missed the whole point of the book.............

Entropy will have its way....................

Aliens might be able to do it, but humans scientists would always insist any evidence aliens had done it was being peddled by crazy conspiracy theorists.

Assuming that the Universe is expanding, the aliens are expanding with it.

Assuming that the Universe is 14 billion years old, then any event that is expected to happen in 100 billion years is nothing but pure speculation, designed to get people to read articles.
If the Universe is expanding like the article implies, then eventually, after a very long time, a few trillion years, perhaps, Mars will be so far from Earth that we will not see the light from it.
Frankly, my dear, I don’t give a damn.

I’m wondering if aliens can do this, can they grow hair on my bald head?

We won't have this problems, Liberals will make sure our population does not grow, Communism and Islam will take over, to ensure we're stuck on this planet forever.

The presence of dark energy in our universe is causing space to expand at an accelerating rate.

It’s cute how they describe an hypothesis as though it was a fact.

Humans first need to figure out how to move the Earth farther from the Sun as it heats up and expands.

If we could shoot the mass of Al Gore toward the Sun near the speed of light that would probably do it.

Not a sphere, but Ringworld is an interesting book about a ring, rather than a sphere.

Could aliens harness stars...

Only legal aliens should be able to. But, the left will want any aliens to have the option.

[a fool in paradise]

This will make for endless taxpayer funded research grants...

Instead of a Dyson Sphere, how about a Dyson Ball? Would that work?!

[plain talk]

Hooper notes that such a scenario is still very far off—on the order of 100 billion years from now. But he also notes that if aliens were grabbing stars from one galaxy and transporting them back to another, the time for each trip would be on the order of billions of years. Thus, they would have to be doing it now, before they run out of time.

The article says that galaxies are moving apart but stars within the galaxies are staying together due to gravity. At least that is how I read it. There are 250 billion stars in the Milky Way. This articles says aliens would be 'fetching' stars in nearby galaxies before they run out of time. Any civilization advanced enough to do that could survive quite well by harvesting the resources they already have within their galaxy.

Our nearest galaxy is 2.5 million light years away. It is doubtful aliens or mankind ever travel outside their galaxy. The distances are just too great. There is no need for civilizations to travel much beyond their adjacent stars. It would be easier to terraform planets than to 'haul in' stars. :-)

Shirley this must be satire.
