Aliens might be present in universe but dark matter makes us blind, reveals study

In the observable universe, there are more than 200 billion galaxies as per a rough estimate. Dark matter is a non-luminous form of matter which doesn’t emit light or energy which makes it pretty difficult to detect.

Dark matter is said to be a mystery to scientists around the globe.  The limited understanding of the dark matter and energy lead us to blind signals from intelligent alien life. This matter is present in the dimensions which humans cannot perceive.

When a human thinks about other intelligent beings, then they tend to see from their perceptive and conscience. According to the Gabriel de la Torre who is from the University of Cadiz in Spain said that we have limited our vision in the world and it is hard for us all to admit the same. We try to differentiate with other possibilities. The intelligence which is based on dark matter or energy forms makes almost 95 percent of the universe and we are only able to glimpse the same.

The researchers had conducted an experiment by taking 137 people with them. The experiment is based to distinguish the aerial photographs with artificial structures which include buildings and roads from others with natural elements like a river, mountains. For example, in one of the images, a tiny character disguised as a gorilla in order to see if the participants had seen the insertion of the same or not. De la Torre said that it is very significant and representative move which shows how our brain works at the same Same time.

The researchers before performing the experiment, they assessed the participants with a series of questions in order to determine if they are intuitive or rational and at the last, it shows that intuitive individuals can identify the gorilla photo more times than the rational individuals. He added that “ If we transfer this to the problem of searching for other non-terrestrial intelligence, the question arises about whether our current strategy may result in us not perceiving the gorilla.”

In the observable universe, there are more than 200 billion galaxies as per a rough estimate. Dark matter is a non-luminous form of matter which doesn’t emit light or energy which makes it pretty difficult to detect. Also, the dark matter is categorized into two types of matter. The cold dark matter is the particle which is slow and weakly interactive while the hot dark matter is high-speed and highly energized randomly moving particles that were created after the Big Bang similar to how matter and antimatter are known to have originated.

Scientists estimate that of the total matter available in the universe, only 15% makes up as visible ordinary matter while more than 80% is made up of dark matter. It is tough to detect since it doesn’t emit light or energy, however, it has gravitational effects which can help detect and study it further supporting which, countless researchers across the globe are studying it. A recently published paper by Indian scientists in the Journal of Cosmology and Astroparticle Physics disclosed details on dark matter’s effects on gravity.

Back in the 1930s, the first partial evidence supporting the existence of dark matter came to light. By 1970s, scientists came onto the conclusion that since galaxies rotate at a fast speed, the gravity exerted by its own matter might not be sufficient to keep it from bursting and therefore, dark matter theories were brought to life by late 1980s. A number of observations made by scientists with respect to cosmic microwave background (CMB), Gravitational lensing, Redshift-space distortions, Lyman-alpha forest, and other experiments were conducted.

As said, scientists know very little about the dark matter. There are several models as aforementioned that were considered for studying the dark matter and dark energy of which, one was Cosmic microwave background (CMB) which is the remnant radiation released and left over after the Big Bang along with other forms of matter such as matter, antimatter, etc.

Researchers believe that cold dark matter puts a slower velocity in its matter and thus, it is linked to the early universe that facilitated density differences between the early universe and what it is today. When compared to high-energy hot dark matter which isn’t capable of maintaining the pace and density differences required, the latter has been ruled out.

According to a study which was published in the journal Acta Astronautica, it said that the researchers also pose how different classes of intelligent civilizations can do it and they are based on five factors which are biology, longevity, psychosocial aspects, technological progress and distribution in space.
