My Idea What Advanced Alien Life Might Look Like
I have written on this very blog several times about the possibility of extraterrestrial, intelligent organisms existing in the universe. In addition, I've devoted screeds of script concerning the possibility that these beings are not only aware of our existence, but they have had the temerity to visit without an invitation. So, this blog and a follow-up piece will bring my thoughts together, with argument, concerning my latest conclusions on the topic. I have not always thought this way. Hopefully, my musings will coalesce into a coherent, convincing gel of conceptual plausibility. I intend to introduce new ideas and material for consideration and possible discussion. Because of the complexity and the amount of 'ground' to cover, I am forced to split my writings on the subject into two separate blogs.
I'd like to share my thoughts on a subject that's been very much in the news lately. With the release of the sixth set of files by the Pentagon, specifically videos of UAPs, there has been renewed interest and discussion regarding their origin. Of course, there has been widespread discussion about whether UAPs provide evidence for the claim we are witnessing craft crewed by technologically advanced extraterrestrial beings. This is not new. Supposed UAP sightings, at least in the modern era, go back to 1945. Maddeningly, we still have no definitive data to date that support the extraterrestrial hypothesis. There are those who claim that the US have recovered alien creatures, both dead and alive, from crashed space vehicles. Talk is cheap and proves nothing. We need to see the evidence. Kate Kerr says she regularly cavorts in heaven and is on speaking terms with both Jesus and God. As for proof, she provides none. I do not believe a word of it. I wrote a post about this delightful individual; you can find if you can seek. Interestingly, she makes a very comfortable living from her books and speaking engagements. Only in America could she get away with this drivel. It certainly wouldn't fly in my adopted country of New Zealand.
Like many folk, I have pondered the possibility of advanced alien civilisations, and for many years, like most scientists, I believed the universe must be teeming with intelligent life. However, of late I have experienced a paradigm shift in my thinking. I've listened to the physicist Dr David Kipling, who has advanced highly compelling arguments for the opposite viewpoint. His analysis and ideas present several important and difficult 'roadblocks' that must be navigated along the evolutionary path for the development and survival of complex biological beings. His analysis is very persuasive, and as a consequence, I now believe that complex life capable of high technological development is exceedingly rare. Indeed, I'm contemplating the possibility that perhaps we are the only advanced technological species in the vast universe. Of course, this is an extreme position that goes against all that we crave and appears, at least intuitively, ridiculous.
Are we so proud, singular and consumed by hubris, to put forth the idea that we are the pinnacle of life's technological advancement in a universe with trillions of galaxies, each populated by billions of stars? On the face of it, the universe should be teeming with civilisations, many more advanced than ours. But we see and hear nothing. The universe is eerily quiet. Are the myriad civilisations in the cosmos shy? Are they deliberately downplaying evidence of their existence/excellence? Tis a vexed conundrum. Perhaps they fear becoming known to more advanced and pugnacious entities. The late Dr Stephen Hawking thought it dangerous for us to actively signal our presence. As we speak, a fleet of intergalactic space vessels are whizzing across the great vastness of space carrying an invasion force to destroy our civilisation. I doubt it. Remember Douglas Adams' take on the scenario. In his case, an advanced extra-terrestrial hypercivilisation took umbrage at one of our broadcasts hurtling through space at the speed of light. These aliens were particularly prickly and assembled a vast invasion armada to avenge the perceived slight to their misguieded honour. After travelling vast interstellar distances, the war fleet eventually arrives at its destination. As they prepare to unleash their megahyper-destructive, extinction-inducing death rays, a mangy street hound gobbles them up; invasion curtailed. Mr Adams was making a humorous point about our perceived notions of dimensional perspective, or perhaps not.
Even if sophisticated alien species exist in the great void, how could they travel the insane distances between the stars? A cornerstone of cosmology invokes the principle that the fundamental laws of physics are a constant throughout the exceedingly vast universe. To date, all evidence aligns with this intrinsic truth. The cosmic speed limit, 186,000 miles per second, can be reached only by massless electromagnetic radiation. As Einstein elegantly proved, anything with mass cannot travel at the speed of light, as it would require infinite energy. Light takes over four years to travel from our nearest star. The distances between galaxies are in the millions or billions of light-years. How could a hypothetical advanced civilisation send a craft to Earth across the insane distances between our solar system and planets orbiting stars hundreds of light-years away? The laws of physics cannot be denied or bypassed. Much has been written about possible warp travel. In this scenario, energy bends spacetime, enabling faster-than-light travel. Though theoretically viable and beautifully enshrined in mathematics, the energy requirement is immense. A craft would need to consume the total energy of galaxies to remain spatially inert while contorting spacetime enough to cover distances consistent with faster-than-light travel. All this without bending our conceptual reality. I will boldly state that if advanced alien civilisations exist, it would be practically impossible to travel to our humble planet, given the vast distances between worlds. The devil's in the advocate: we could argue that we lack the intellectual capacity to comprehend alternative, sophisticated modes of interstellar propulsion. Mayhap our meagre cerebral capacity cannot grasp alternative modes of faster than light travel. Tis the classic argument from 'personal incredulity'. To this I counter: whilst it is true we don't fully appreciate all that concerns Reality, we have enough knowledge to understand universal principles, constants and constraints. From our insignificant and unprivileged position in the universe, it appears the laws of physics that govern our tiny piece of cosmological real estate are transferable to the rest of the universe. Our observations of the cosmos have found no exceptions.This set of prevalent Laws has been enshrined in the universal concept of the Cosmic Principle.
My overarching point? Even if extraterrestrials exist and are aware of our existence, the distances between us are too great to allow realistic/relativistic communication, let alone visitation. I'll stop there, and continue my nay saying in the second installment. In the next edition, I'm going to double down and profer my additional arguments on why we may well be alone in a cold, insentient, indifferent universe.
