Our population is dilate at an accelerating pace due to cryptic dark vigor . And the major problem is that , finally , everything will be so circularise out that no newfangled stars can form , and the universe ends .
But do n’t give up all Bob Hope just yet . Because a researcher – Dan Hooper from the Fermi National Accelerator Laboratory in Illinois – has suggested a rather novel way extraterrestrial could survive this . They could , he says , move stars nearer together to prolong their existence . His paper is available onarXiv .
“ [ I]n parliamentary procedure to maximize its admission to operable energy , a sufficiently advanced civilisation would chose to expand speedily outward , build up Dyson Spheres or similar structures around encountered stars , and habituate the energy that is harness to speed those superstar away from the go up horizon and toward the center of the refinement , ” Hooper writes .
He remark that in 100 billion years , most star in other galaxy will move beyond the “ cosmic horizon ” , which means you wo n’t be able to see them any longer . And you would n’t be able to reach them , either .
That pose a problem for , say , getting enough vigour to keep your civilization alive . So before all that happens , Hooper suggests that alien could practice space vehicle to grab stars from elsewhere and contribute them closer .
To do so would require a structure like the said Dyson Sphere – which involve capsulise a star in some sort of structure to harness its energy . Hooper does n’t furnish an exact method for doing this , but he does note that star slightly little than the Sun will probably be serious , as they ’ll live quite a retentive time and provide a decent amount of free energy .
“ If we eff that all the fossil fuels were only go to be there for another decade and then they ’d be gone … I guarantee you we ’d snaffle it all so we could use it eventually , ” Hooper toldNew Scientist .
He added toScience Newsthat if aliens were already doing this , then we ’d be able to spot them doing it . A deficiency of stars in one region , for example , could be a planetary house that alien have already scoop them up for personal usance . Sneaky .
In both articles , it ’s noted that it might but be easier to expand your civilisation with the universe , or use the existing clusters of headliner – namely , galaxies – that already exist . Aliens could just move to a more dumbly populated bunch .
Ultimately any civilization will be doom in about 100 trillion years , when the last stars are expect to pall out , regardless of where they are . In that intervening time , however , you might just want to stock up on as many stars as you may .
