8. Touched: The Extreme Experience Research of Dr. John Mack
Touched: The Extreme Experience Research of Dr. John Mack is a film that explores the widespread phenomena of people who claim to have encounters with aliens. Dr. Mack was a Pulitzer Prize-winning author and Harvard Medical School professor. As a psychiatrist, he worked with patients who believed they had been abducted by beings from another world.
Mack wanted this extraordinary film created, prompting him to seek the assistance of filmmaker Laurel Chiten. At first, Chiten noted she was uncertain about getting involved in the production of the film. However, her perspective shifted when she had the opportunity to meet with some of the individuals whose experiences were to be featured in the film. Their compelling stories ignited Chiten’s fascination with the profound human emotions entwined with the phenomenon of alien abduction. Chiten said she was driven by a curiosity to comprehend why a highly esteemed professor like Mack firmly believed in the authenticity of his patients’ encounters.

Von Däniken spent five years documenting physical evidence that indicates humanity has been visited and influenced by ETs. In this film, he provides viewers with evidence showing that galactic travelers have been visiting all the major continents around the globe for a very long time.
How Interest in Alien Life Has Evolved
Interest in UFOs/UAPs in Academia
According to a study published in the journal Humanities and Social Sciences Communications, even the academic community is showing interest in the study of Unidentified Aerial Phenomena.
Of study participants, 37% ranked the importance of continuing research into Unidentified Aerial Phenomena as absolutely essential or incredibly important. When considering the significance of academia’s participation in research related to Unidentified Aerial Phenomena, 64% expressed that the academic community’s participation is extremely important or absolutely essential.
Inside America’s UFO Investigations
Due to an increase in the number of Unidentified Flying Objects/Unidentified Aerial Phenomena, seen over military-controlled training areas, in May 2022, Congress held a hearing to explore whether UFOs are visiting the planet.
Because of this increase in UFO sightings, Congress instructed NASA’s Near-Earth Object (NEO) Observations Program to locate 90%, or more, of foreign objects larger than 140 meters that pass close to the planet.
Government Admission of Alien Life
In March 2023, Pentagon officials released a document stating that alien visitation to our solar system is possible.
Then, in April 2022, the government revealed three declassified UFO videos. However, since officials are examining more than 650 potential UFO sightings, these declassified videos represent a very small number of the potential UFOs that American officials are in the process of investigating.
With all the information coming forward, people around the world are paying attention to what ufologists, government officials, and experts have to say about the phenomenon of UFOs and the potential for alien life. This expansion of awareness is why alien docuseries and TV shows are so popular.

Harvard Professor Avi Loeb Says Universe Created in a Lab

One of the greatest mysteries of our universe is the question of what existed before the Big Bang and how our universe was created. Could it have been created in a lab by a higher form of intelligence—an extraterrestrial intelligence?
Scientists have studied for years the possibilities that may have created the Big Bang; how our universe was created. Now, Avi Loeb, Harvard Professor of Science and author of “extraterrestrial: The First Sign of Intelligent Life Beyond Earth,” proposes in his latest editorial for Scientific American that our universe may have been created in a lab.
Modern physics has a problem, we do not yet have a good understanding of how to unify quantum mechanics and gravity. If we did, we could in theory figure out how to create a “Big Bang.” This idea led professor Loeb to his theory.
“If we imagine a civilization that had science and technology for much more than a century like we did, then they could have arrived at a theory that unifies quantum mechanics and gravity, and if they figure out how the Big Bang can be created perhaps they could also produce it themselves in the laboratory,” Loeb said. “And if that happens then there is a very interesting possibility, just like in nature, for example, a chick comes out of an egg, becomes a chicken and lays another egg, and so forth. You can imagine a universe like ours giving birth to an intelligent civilization that can create a universe like the one that made it.”
Imagine if different civilizations were given a letter grade; professor Loeb puts us at a Grade C, while the more advanced civilizations have higher grades.
“One can, in principle, classify civilizations in the universe into different classes. Type C civilization is similar to ours where we rely on the sun to keep us alive and we are using our environment the way it was provided to us. But then one can imagine a civilization Type B, which is not dependent on the star next to which it was born, in. fact it can create a habitat that supports its life far away from the star,” Loeb said.
“You can imagine them creating a platform where a civilization can live happily, using nuclear energy supplied to it from nuclear reactors and not from the star that it happens to be born next to, that would be Type B. Then Type A civilizations would be those that are capable of recreating the astrophysical environment that they live in, in particular, the universe as a whole. So, creating a universe in the laboratory implies that you’re at the top of the class of civilizations in the universe. We haven’t reached that yet because we don’t have a quantum theory of gravity.”
