Astrophysicist theorists periodically suggestoriginal hypothetical cars of a stellar scale, the creation of which is impossible now, nor in the distant future, but their design provides a huge field for theoretical development.
One of these installations is the engineShkadova, which is constantly “modified” by scientists in order to develop more efficient stellar megastructures. The latest development of astrophysics from the University of Illinois in the USA has significantly improved the efficiency of the system on paper and, in theory, “moved” the solar system a considerable distance.
The classic Shkadov engine isa mirrored solar sail, which balances the force of gravity and the pressure of the light flux emitted by a star, in our case, the sun. As a result, the sun and sail are in equilibrium, but traction occurs in the system. Shkadov’s classic “clean” engine allows for one million years to move the solar system with a star sail by 0.03 light years, using half the light radiation of our star.
Advanced by Matthew Kaplanthe interstellar machine scheme involves creating a system of huge solar panels (Dyson's swarm) concentrating the solar wind in a strictly specified direction to move hydrogen and helium to a giant space station. The thermonuclear engine at the station creates jet jets, one of which is hydrogen, will balance the system and is aimed at the star, and the opposite - oxygen will accelerate the system.
At the same time, the effectiveacceleration of the Sun-station system, as a result of which our Solar system can move for 50 light years in 1 million years, and this is a significant distance that allows us to dodge global cataclysms in the Universe in time, such as a supernova burst.
