New Study On Alien Life Within The Cosmos

Search For Extraterrestrial Intelligence

The search for extraterrestrial intelligence has surely progressed over the last century with the likes of the Breakthrough Listen Project, NASA missions to Mars, the Voyager satellites, and much more. However, despite our ever-expanding knowledge of the universe we live in, alien life still remains hidden.

Five years ago astronomers stated that there are roughly 40 billion Earth-like planets that orbit habitable zones within our own Galaxy. The more we know about where we live, the less likely it becomes that we are alone. Yet, for all the signs pointing to the existence of alien life, it is still to be discovered.

A paper recently published by three researchers from the University of Oxford throws the possibility of extraterrestrials being discovered into doubt.

Like many before them, they have pondered the Fermi Paradox. The Paradox simply states that if we live in an ever-expanding universe with a seemingly endless number of worlds in which life can develop, why have we not discovered it? Where is everyone?

Indeed, this last question was asked by physicist Enrico Fermi almost 70 years ago. Initially intended as a joke his question casts doubt on the possibility of extraterrestrial life.

With our Milky Way galaxy estimated at being 13.51 billion years old, there has been ample time for other sources of life to develop intelligence like us. This is not only enough time for extraterrestrial intelligence to develop before us, but to also travel throughout the galaxy and colonize other planets.

Alien Life

But, for all the time and huge possibility that we are not alone in the galaxy or the universe, the scientific paper says otherwise. The Oxford study estimates that there is a 53% chance of humans being the only intelligent life form in the Milky Way and a 40% chance of being alone in the Universe.

Perhaps our own surroundings have given us false hope in the search for alien intelligence. After all, life is vast and bountiful here on Earth, but the circumstances in which this life developed are rare. Just think about all the molecular details that had to be in perfect balance for life to come into existence on this planet. Details from the correct components, weather patterns, climate, distance from the sun and much more.

But, as we know, microbe life does exist on other planets, moons, asteroids and within space itself. NASA themselves have recently released details about Mars once containing proto-life.

So, if we are yet to discover the existence of aliens, what is the reason?

Fermi Paradox

Although there are many stories in alien news outlets claiming to have the proof of extraterrestrial beings, nothing definitive has ever been shown.

The Fermi Paradox proposes three possible reasons why humans are yet to discover extraterrestrials.

  1. Aliens do not exist. As proposed in the Oxford Study, the existence of otherworldly beings is just a fantasy. We are alone in the universe and must deal with that.
  2. Alien life does exist, but it has not developed into an extraterrestrial form of intelligence. This would mean that life on other planets may develop and evolve, but not in the way we have on planet Earth. Think about it, for all the millions of creatures in our world, we are the only ones to reach this level of intelligence.
  3. Extraterrestrial intelligent life does exist but remains quiet. Perhaps we are still so unevolved that we are not worth a response. Alternatively, beings from another world may be wary of communicating with one another due to the possibility of war and destruction.

Are we alone in the Universe? This is the question we all want an answer to. However, are we ready as a civilization to know what the answer really is?

As Arthur C. Clark famously said: “Two possibilities exist: Either we are alone in the universe or we are not. Both are equally terrifying.

  • The observable universe is so vast the human mind cannot comprehend it. We can roughly measure it, but we cannot comprehend that distance. No one can. Also, the observable (known) universe is almost certainly not the entire universe. That universe may be millions, billions, or trillions of times larger than the observable universe. It is even likely that it is INFINITE. We just don’t know because we can’t see it and never will (because the light will never reach us because the universe is expanding). There are more stars in just the observable universe than there are grains of sand on all the beaches of the Earth, down to the bedrock, and many times that number of planets. To say that only on Earth has life developed and evolved is typical human hubris. (Also, when it comes to intelligent life, maybe we aren’t as intelligent as we like to think.) Most of space (over 99.99999999%) is just empty space. Finding life in that with our crude instruments is probably a fool’s game. Logic dictates that life is inevitable where conditions allow it to arise, and there must be many, many planets where conditions allow it, although granted there are far more planets where conditions do not allow it.
