At some point in the far future tense , our descendants may need to relocate the Sun — a suppositional megascale labor referred to as leading engineering . But as crazy as that vocalise , the physical science order it could solve . Here ’s how we ’ll do it .
A Type IKardashev civilizationwould use the power of its total planet . Type II , a whiz system , and a Type III would harness the push of an full galaxy . It boggle the mind to think about the engineering ask to rearrange the stars of an entire galaxy .
How to Measure the Power of Alien Civilizations Using the Kardashev Scale
But is it really potential to move a star ? Could we actually move theSun ?
Earth will turn into a Venus - like hell earlier than antecedently suppose
This approximation was first proposed by physicist Dr. Leonid Shkadov in his 1987 report , “ Possibility of command solar scheme motion in the galaxy ” .
Here ’s how it works .
A future alien civilization would reconstruct a gigantic reflective structure on one side of its star . sparkle from the asterisk would attain this structure and bounce off , pushing it away .

If this broody structure had enough sight , it would also pull the star with its gravity .
The star would be trying to advertize the structure away , but the structure would be pulling the mavin along with it .
If afuture civilizationcould get this in perfect Libra , it would be able to “ pull ” the whiz around in the galaxy , using its own starlight as jab . At first , you would n’t get a lot of speed . But by directing half the energy of a star , you could get it moving through the galax .
How to detect monumental alien spaceship powered by stars
Over the line of a million years , you would have change its velocity by about 20 meter / second gear . The adept would have traveled about 0.3 sluttish year , less than 10 % of the way to Alpha Centauri . Keep it up for a billion years and you would be run a thousand times quicker . Allowing you to journey 34,000 clean twelvemonth , a significant portion of the galax .
Imagine a succeeding civilization using this technique to move their stars to better locations , or even rearrange huge portion of a wandflower for their own energy purpose .
This may sound theoretical , but Duncan Forgan , from the University of Edinburgh suggests a hard-nosed way to search for alien moving their stars . According to him , you could utilize major planet - hunting telescope like Kepler to observe the eccentric light signatures we ’d see from a Shkadov Thruster . There ’s nothing in the law of physics that says it ca n’t happen .
It ’s playfulness to retrieve about , and gives us another fashion that we could explore for alien civilizations out there across the galaxy .
