A few years ago, an astronomy professor at Columbia University, David Kipping, guessed that hypothetical alien civilizations might zap black holes using lasers to explore the galaxy invisibly. So is this the reason why haven’t we found aliens in space yet?
Why does the human race think intelligent life would exist?
The reason many people and scientists think intelligent life would exist is because of probability. The universe is so big, even if aliens are extremely rare, many assume that extraterrestrial life has or will have evolved somewhere among the estimated billions of planets.
Intelligent life may have evolved like animals but may not be advanced enough to contact our planet. After exploring various worlds closely, some people do not think aliens exist in the solar system and have not found any hint. However, many scientists look elsewhere for a shred of evidence.
Humans Searching in hard to reach places for Extraterrestrial Life
Now, a geologist explains humanity’s search for intelligent life in space is the wrong place.
The advanced telescopes and numerous space exploration have helped humanity unveil many exoplanets from which some have similarities to our planet. These star systems refer to the planets with atmosphere and temperature the same as Earth flourish. The star systems are dimmer than by our sun and governed by the red dwarf stars.
Let’ take what Professor Kipping said as an example, “If they’re so numerous, so long-lived, potentially trillions of years, and so they seem to have everything going for them.”
“It’s odd then that we don’t live around a red dwarf,” he added.
He presented the “red sky paradox” in the latest paper published in Proceedings of the National Academy of Sciences’ June issue. In the article, the astronomy professor argued that even if the red dwarf stars are known as five times more yellow stars like our solar system’s sun that possibly sustain planets like Earth, the life we know exists on the yellow star systems. Besides, no evidence is found that life exists on red dwarf star systems.
Kipping suggested solutions to the paradox by developing three possibilities with his team: Chance, Circumstance, and Lifespan. He then made an argument that the paradox can be solved. First, if something keeps the red dwarf star systems from developing Earth-like life or humanity is extraordinary. Lastly, if red dwarf starts are about trillions of years in lifespan, making them not age yet.
Other Reasons Why Humanity Have Failed to See Aliens
If scientists fail to evidence that life exists in red dwarf star systems, it indicates that life found on Earth is more memorable. However, if life’s development process is universal, the paradox that humans have not found life with five times more red dwarfs and billions of sun-like stars becomes even more vital.
Meanwhile, here are other reasons why we have not found aliens yet:
Aliens are Hibernating
Based on the “aestivation hypothesis,” most aliens hibernate. It is like our bears, but for more extended periods. The scientists assume that any advanced civilization eventually merges with machines to form an entirely digitized society that has the capabilities to think, act, and function beyond imagination.
However, the problem is the cooling. For instance, the Earth’s processing systems are ten times more efficient if in an environment that is ten times colder. As a result, digital aliens may consider the logic of hibernation for a few trillion years or while the universe still expands and cools. So, they can have more processing power to do critical activities, such as conquering the galaxy.
Most Young Rocky Planets Have Extremely Unstable Climates
According to the “Gaian bottleneck hypothesis,” most young rocky planets not older than one billion years come with volatile climates. So, these planets will eventually grow too cold or too hot for life to exist for a long time.
About four billion years ago, planets had the proper conditions to hold life or even became a sanctuary of simple microorganisms. However, only early life on Earth has evolved rapidly since the world releases many gases into the atmosphere necessary to stabilize the climate. Perhaps the reason for not finding intelligent life yet is because they are all dead.
Intelligent Life Flourishes in a Completely Different Environment
Another possible reason aliens are still elusive is that they could flourish in an environment safe from radiation and temperature fluctuations. Worlds like Enceladus, Europa, and Pluto have an icy shell above a massive underground ocean that may offer a better incubator for aliens than planets like Earth, which are vulnerable to high-energy radiation and extreme temperature striking the surface.
If that is the case, any alien would be swimming in these worlds. This scenario shuts them off from the rest of the universe, making it impossible for them to communicate.
Dark Energy Split Earth life and Intelligent Life Apart
The universe expands while galaxies move farther apart. So, we see distant stars appear dimmer. Those are because of dark energy, an invisible substance. Scientists speculate that in a matter of a few trillion years, that substance will eventually stretch the universe, making us no longer see any galaxies’ light beyond the closest cosmic neighbours. So, if we do not explore the universe as early as possible, we may lose the chance of finding aliens forever.
The stars become entirely inaccessible and unobservable, according to some scientists. That means humans are on a strict deadline to discover and meet aliens. If we want to keep ahead of the so-called dark energy, we need to expand our civilizations into galaxies before drifting away. The more galaxies being reached, the better.
However, fueling that growth is not an easy process. Rearranging the stars might be necessary, but also, we must continue to search the Earth and the oceans.
All of the ideas above are critical in making a significant number of assumptions about how aliens would evolve, operate, or communicate. Thus, while there is new evidence about their existence, humans are still motivated to search for what may be human history’s most significant discovery – the aliens.
