Star engines: When galaxies emit light, their expansion reveals a unique phenomenon

(ORDO NEWS) — Galaxies emit light. According to Einstein’s theory of relativity, radiation energy is equivalent to mass. This means that the galaxies are losing mass, which means that their gravitational connection is weakening, and the orbit of their stars should expand.

What I have outlined above is quite simple, although I have not been able to find it published anywhere in the scientific literature.

Therefore, I decided to write a short article about this to encourage observers to collect future data to confirm this phenomenon. The article was accepted for publication in just two days and set my personal record for the shortest time between conception and publication of a scientific idea.

Another way to think of the effect I’ve described is that galaxies like our own Milky Way are held together by gravity. If the mass of the Milky Way decreases, the Sun’s orbit around our galactic center should expand.

This effect occurs for the same reason that the Earth‘s orbit around the Sun expands as the Sun emits radiation and loses mass. In the context of the Earth, this movement is tiny – about four inches per decade. Gravity can be thought of as a spring that connects the Earth to the Sun, and as the spring weakens, the Earth shifts.

The movement of a habitable planet, such as Earth, away from the host star can make the planet slightly colder, and so can be counteracted by a “planetary engineering project” of an advanced technological civilization.

The goal would be to push the home planet inward to keep its light intensity and average surface temperature constant for an extended period of time. If astronomers develop instruments that can achieve the necessary sensitivity to detect the expected migration of a habitable planet away from the host star, and fail to detect the expected movement, then this could reveal the existence of a major engineering project to artificially move the planet.

The speed of the expansion of the Sun from the center of the Milky Way is a billion times faster than the migration of the Earth from the Sun, and reaches a value of ten inches per second. This expansion rate may be even greater for stars inhabiting more luminous galaxies.

The fastest expansion rates of galaxies can be detected by high-resolution spectrographs on the next generation of ground-based telescopes, such as the high-resolution spectrograph at the European Very Large Telescope or the G-CLEF echelle spectrograph at the Giant Magellanic Telescope. Achieving the required sensitivity will take us one step closer to spotting stellar engines that deviate from their natural gravitational path.

Representing a larger engineering ambition than planetary engines, stellar engines are hypothetical megastructures that extract energy from a star to generate thrust and acceleration. A qualitative idea of ​​stellar engines appeared as early as 1937 in Olaf Stapledon’s book The Star Maker: with their accompanying systems of worlds across the vast ocean of space separating the two floating islands of civilization.”

The astronomer Fritz Zwicky, the discoverer of dark matter, clearly articulated the stellar engine in his characteristically broad monograph titled Morphological Astronomy: “If you consider the Sun itself, you can imagine many changes.

Perhaps most fascinating is the ability to accelerate it to higher speeds , for example, 1000 km / s in the direction of α-Centaurus, in the vicinity of which our descendants may be in a thousand years. All these projects can be implemented using nuclear fusion jet engines using the matter that makes up the Sun and planets as nuclear fuel. ”

In 1987, Leonid Shkadov proposed a specific design for a stellar engine in which a giant mirror was deployed to reflect some of the radiation back to the host star. Since then, other projects have been actively discussed.

In the near future, SpaceX will launch a 400-foot-tall starship, the largest rocket in human history. If there are smarter kids in our space quarter, then the obvious question is: how much more ambitious are their rocket attempts? Time will tell if we should be inspired by their achievements or vice versa.
