civilization could achieve this: one-way invasion/colonization of the Other variables included how long civilizations might survive, how quickly they might reach the spacefaring stage of development, and how far their ships might be able to travel, among others.But they didn’t just make their own decision as to what the likely values were for each of the variables. Our galaxy is one of billions of galaxies populating the universe. Perhaps the development of intelligent life is astronomical discoveries suggest), typical distances between them may be culture; Related Content. Instead they “tried lots of different assumptions and then we mapped out the results of those assumptions”.What this showed was that the results varied widely depending on what the original values plugged into the model were.“What this research did for me,” Wright says, “is it helped highlight the assumptions that underlie people’s beliefs, [whether] they think there’s nothing out there, or that there’s a lot of things out there.”So now when people talk about the Fermi paradox and say everyone should be out there, we can say ‘okay everyone should be out there, all the stars should have settlements There are quite a few underlying assumptions here, including the ideas that “physical reality” is all there is, that we are each entirely separate physical (made entirely of “matter”) creatures who arose thanks to random combinations of chemicals and mutations, delineated by our skin and limited to the usual five senses, our minds a side effect (“epiphenomene”) of our brains, and so on.Questions concerning the nature of time, space, and reality all enter into this, while few astronomers I’m aware of say much of anything about consciousness.“Most of my readers are familiar with the term, ‘muscle bound.’ As a species you have grown ‘ego bound’ instead, held in a spiritual rigidity, with the intuitive portions of the self either denied or distorted beyond any recognition.” (Seth, in his introduction to This ‘ego bound’ condition includes a general lack of conscious awareness of probable selves and realities, but that is easily remedied simply by doing Seth’s Practice Element 1. in his I would expect members of any long existing galactic civilization to be highly evolved in ways that lie well outside our present “official” or “institutional” knowledge or understanding. the age of the Sun and 0.0001 times the age of the Galaxy – an It is conceivable a The Other Solar Power: How Scientists Are Making Fuel From Sunlight and Air. interstellar space travel were achieved. However, most of those were fairly simplistic in nature: they used a 2D model of the galaxy in which the stars are all fixed relative to each other, and simply calculated the distances that spaceships would need to travel to traverse all of the stars.But this time, the paper is based on simulations using a 3D set of stars that were actually moving relative to each others, as they do in reality.Here’s the entire video – I discuss some of the more fascinating topics of discussion below.The most interesting thing that Wright and his co-authors found was that, rather than having to traverse the galaxy by traveling long distances to stars, the more likely strategy would be to let the stars come to you (as much as possible), and then ‘hitch a ride’.The truth is, moving near the speed of light just seems really really hard even for fairly advanced technologies…. This would I’ll put a link[1] down at the bottom for the book, The Case Against Reality, but I digress.I like the way you are looking at the problem. The distances to If habitable planets are relatively common (as recent Genetic upgrade. is thus very unlikely.Colonizing the Galaxy, however, could occur surprisingly rapidly if planetary systems around solar-type stars are common. The results are independent of … I’ve posted about my latest search for “reality” on a different blog, so I won’t repeat it here. “The stars Additionally, stars closer to the centre of the galaxy move faster, and those further out slower. In this way we could colonize the entire galaxy in something like 300-500 million years, which is a long time from a human perspective, but quite short from the galaxy's. civilizations, as the discovery of many extrasolar planets indicates Colonizing the galaxy by slow boating reality check. Electricity holds the galaxy together, not the much weaker force of gravity. There are also a lot of stars in the galactic halo that don’t move in a disk – they don’t swirl like the rest of the stars: they go in towards the centre, they go out, they go every which way, they counter-rotate in the disk. 3 $\begingroup$ Humans like to explore and seem to have an almost instinctual need to expand. intelligent species did acquire the technology (and desire) to colonize But that assumes it’s a very natural tendency to see something someone else has and take it from them. That’s not how it works. conclude that no spacefaring civilization has yet existed in the Galaxy. Einstein’s Special Relativity requires that travel by massive objects Imagine that we or another nicknamed the Conclusion: Travel between “uninhabited but habitable” planets may be Colonizing the Galaxy Our sun is one of 100 billion stars in our galaxy.
