Are We Alone in the Universe?

There are three deep questions that philosophers and scientists continually raise in their quest for enlightenment: What is the meaning of life? What kick-started life? Are we alone? Now, as humans we are virtually still in our infancy, having existed for a mere 200,000 years on a planet that is 4.5 billion years old (pretty difficult to comprehend how slow evolution takes to create physiological changes.) When you unpack our anatomy, both chemically and biologically, you’ll notice that we are comprised of the same “stuff” that pervades the universe. Astonishingly, we’re as much related to the universe as it is to us. However, stumbling upon another species that is more or less intelligent than us would be a significant milestone, considering that we have only been exposed to our own biosphere. However, things would change. Determining whether or not the extraterrestrials were hostile or benevolent would require us to tread lightly.

Given the gargantuan number of stars existing in our galaxy alone (100+ billion), it would be naive to say that life couldn’t form on any of these surfaces. Exoplanets—planets that are orbiting a star that is different than ours—are being discovered by the boatloads. Astronomers are shrewdly sifting out which planets are eligible to be exoplanets by recognizing certain light emissions and measuring distances from the star and the planet. Scientists swoon over these observances because it brings them one step closer to finding planets that are able to sustain life. Life, according to our standards, needs to be in a proximate distance from the sun in order to be viable. This zone is called the “Goldilocks zone.” When you exist in this region, your climate is neither too hot nor too cold. Earth, of course, teems with life because it is perfectly seated in that destination. Also, water is vital to survival and the conception of life because it can mix organic compounds together. It is only a matter of time until we find a twin-earth that has been around long enough to have life emerge into a multi-celled organism. Scientists are dutifully and cleverly using tactics to efficiently weed out all of the planets that do not satisfy the “habitable planet” criterion.

But what if life does not have to be based on a human-encoded rubric? What if life can exist interdimensionally? Firstly, if life can exist without the chemicals that are strewn throughout our molecular structure, then it is probably safe to say that life is abundant in the universe. Secondly, we cannot tackle such a question without having known that the other species is definitely disparate from us. But, let us think hypothetically: If this species were entirely made up of an undiscovered element, rather than our 6 elements (oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus), then we would have great trouble analyzing it. If they are thousands of years ahead of us technologically, then we would concede their dominance in an instant. Anything that much more advanced than us is indistinguishable from magic. If you take a peasant who existed in the barbaric medieval age and give him a glimpse of what life is like today, he would be befuddled and flabbergasted within seconds, taken aback by unsettling thoughts such as “how’s that even possible!?” Technological growth is exponential, and these beings may be able tap into interstellar travel as easy as it is for us to ride a bike. Such a scenario is totally plausible when you think about how far we have come in the last century alone.

Interdimensional life that may thrive in a higher dimension would be peculiar and unquantifiable. Since we exist in 4 dimensions (length, width, height, and time), we cannot wrap our heads around anything existing elsewhere. Scientists theoretically postulate that there are 10 dimensions, which ultimately leads to infinite universes e.g., string theory (yes, I know, sounds preposterous.) Some scientists even posit that our universe is one among many that pop in and out of existence like little bubbles. As dehumanizing as it sounds, it shows the complexity of all things and how meticulously we are all interconnected. Therefore, it is a lot more reasonable that we find aliens of our nature than anything else. We are simply not evolved enough to witness imperceptible beings who dwell in other dimensions.

Would aliens be hostile or benevolent? That is an undeniably hard question to answer. But we can be introspective and take a look at ourselves. Human nature tends to be selfish and altruistic. In order for us to propagate and survive, we had to be cooperative. However, we also had to preserve our evolutionary upbringing. It is all in our genes; some people are more helping and caring than others, mostly not by choice. Of course you can acquiesce and override those natural feelings to do something you want, but only to an extent. When it comes to good and evil, we lie in the middle of the train tracks. For example, people are ostensibly “good,” but behind closed doors they may be malicious and duplicitous. The worst possible scenario in discovering intelligent beings would be to find ones that are plundering planets because they need to colonize somewhere. These beings would not be kind in their approach to obtaining our resources. But when you think about it, if we were on our last leg of existence and we knew there was a prospering, less-evolved life form in our backyard, would we aggressively seek out our necessary ingredients to survive? Most likely, given our track record, but we have not yet been pushed against that wall.

There most likely is other life out there somewhere, just based on probability. Until we find “them,” we should be wary in our approach to discovering them in case they’re unfriendly. Space exploration is an important sector of science because it provides us with a way to expand our resourcefulness, rather than remaining bound by earth’s finite assets. UFOs that have been spotted in our atmosphere are mostly bunk and, if anything, anomalous behavior. Even if they were actual extraterrestrials, and that is the way in which they choose to communicate with us, then they are certainly not doing a good job of it. Most UFO observers eventually get exposed or are just delusionally unscientific. It would be cool to find different life out there; we’d gain a lot of uncharted insight. I just hope I am alive for the eureka moment.
