It didn’t come to us. It waited in place, like a buoy on the surface of the ocean, until the ‘ship’ of the solar system ran into it. To make things clear, only one of 500 stars in the system is as much at rest as Oumuamua. The probability of that is very low. After all, if it were a stone that was simply hurled from a different solar system, we would expect it to have the velocity of its star system, not the average velocity of all the thousands of stars in the vicinity.” Quoting: Zataranno If it wasn’t comet outgassing, what force caused Oumuamua to accelerate? It is precisely here where Loeb enters the picture. According to his calculations, Oumuamua’s acceleration was caused by a push. “The only hypothesis I could think of,” he relates, “is a push from solar radiation pressure. For that to work, the object would have to be very thin, less than a millimeter thick, in other words a type of pancake. In addition, the Spitzer Space Telescope found no evidence of heat emission from the object, and that means that it is at least 10 times more reflective than a typical comet or asteroid. What we have, then, is a thin, flat, shiny object. So I arrived at the idea of a solar sail: A solar sail is a spaceship that uses the sun for propulsion. Instead of using fuel, it is propelled ahead by reflecting light. In fact, it’s a technology that our civilization is developing at this very time.” “We have no way of knowing whether it’s active technology, or a spaceship that is no longer operative and is continuing to float in space. But if Oumuamua was created together with a whole population of similar objects that were launched randomly, the fact that we discovered it means that its creators launched a quadrillion probes like it to every star in the Milky Way. It’s possible that space is filled with sails like these and we just don’t see them. We only saw Oumuamua because this is the first time we’ve had technology that’s sensitive enough to identify objects of a few dozen to hundreds of meters in size from the illumination of the sun.

It also just makes way more sense. Last Edited by Zerubayah on 01/14/2019 11:26 AM |

I have spent a couple of years banging my head against it and it appears to be pretty solid. Last Edited by Zerubayah on 01/14/2019 09:19 AM |
