Aliens May Pilot Stars With 'Mega Mirrors' - And If They Do, We Can Find Them

alien sun mega mirrors

Aliens may be piloting their stars through the galaxy - and we might be able to find them.
The idea of a solar engine itself dates back to 1948, when the astronomer Fred Zwicky - who co-discovered dark matter - suggested that advanced civilisations might be able to navigate the path of the entire solar system through the galaxy.
He proposed that by using massive 'bullets' made of nuclear fuel fired at the sun, it might be possible to create explosions able to propel stars through space - taking us and the other planets with it.
Discovery.com adds that in the late 1990s the idea was taken up by the physicist Leonid Shkadov, who said that using a massive spherical mirror radiation from the Sun could be reflected back onto its surface - causing a force that would push it through space.
Such devices might be necessary if a civilisation wanted to avoid the sun passing through a cold cloud of molecular hydrogen - which can cause serious climate change - or passage close to another star.
Needless to say, building such a device is far beyond any technology we can imagine.
But that's not to say that in the enormous variety of the galaxy, or beyond, someone hasn't managed it. And if they have, they might be leaving tell-tale signs behind that mean we might be able to find them.
