A new model based on the famous alien-hunting Drake equation suggests that some parallel universes within the hypothetical “multiverse” could have higher chances of containing extraterrestrial life than our universe.
The approach presented in the paper involves calculating the fraction of ordinary matter converted into stars over the entire history of the universe, for different dark energy densities.
The model predicts this fraction would be approximately 27% in a universe that is most efficient at forming stars, compared to 23% in our own universe.
This means we don’t live in the hypothetical universe with the highest odds of forming intelligent life forms. Or in other words, the value of dark energy density we observe in our universe is not the one that would maximize the chances of life, according to the model.
If we take the mortal danger of the “Tic-Tac” UAP maneuvers literally, we need to believe that “these objects suggest a form of physics we have not yet discovered,” says one sci-fi writer.
Researchers have developed a new method using the Allen Telescope Array to search for interplanetary radio communication in the TRAPPIST-1 star system.
A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, for example, to ones used to communicate with the rovers on Mars. Penn State astronomers and scientists at the SETI Institute spent 28 hours scanning the TRAPPIST-1 star system for these signs of alien technology with the Allen Telescope Array (ATA). This project marks the longest single-target search for radio signals from TRAPPIST-1. Although the team didn’t find any evidence of extraterrestrial technology, their work introduced a new way to search for signals in the future.
A paper describing the research was accepted for publication in the Astronomical Journal and is available online as a preprint.
Discovering Advanced Civilizations: Type 1 To 7 And Minus 0 To Minus 3: How Far Can We Go?
he kardashev scale type From Type 1 To 7 And Theand Reverse Scale: How Far Can We Go?
The Kardashev scale is a method used to determine a civilization’s technological advancement, which divides civilizations into three types, with type 1 being the simplest civilization of all.
The civilization created by the human race is not yet advanced enough to be considered a type 1 civilization. How long until we reach that classification? Stay to find out.
“Introduction“
Astrophysicist Nikolai Kardashev developed the Kardashev scale in 1964 to determine some characteristics that would facilitate the search for extraterrestrial life.
After analyzing several conditions in the history of the human race, Kardashev realized that there is a need that grows as civilization does, energy.
As the human race has expanded worldwide, so needs for energy.
Suppose this is inherent in all species that become an intelligent race. In that case, a hypothetical race of aliens who come to forge a civilization as significant or more extensive than that of humans will eventually also have an energy deficit.
To solve this energy need, an extraterrestrial race must develop technologies to meet the demand for energy needed to sustain all members of their civilization.
Kardashev theorized that in this sense, there must be 3 types of civilizations:
Type 1: A civilization that can harness all the energy its home planet gives them.
Type 2: A civilization that can harness the energy of its entire solar system.
Type 3: A civilization that can harness all the energy provided by the galaxy it is in.
“A type VII or K7 civilization would travel, transcend and ultimately oversee or ”be” the Omniverse which is the collection of every single universe, multiverse, megaverse, paraverse, 11d dimension, and 1st realm (reality). Everything is in the Omniverse, and there is only one Omniverse.” In other words, such a civilization would be as closest as godly as possible.
However, the achievement of a type 7 civilization will only be the end of a very long process of technological advancement and connection with the cosmos. To get there, we would first need to go to all the other civilization types that make up the scale. Let’s see what they consist of.

However, Dr. Robin Wordsworth of Harvard University and Dr. Charles S. Cockell of the University of Edinburgh argue that this focus has left unexplored possibilities for life in environments that don’t resemble our own.
In a preprint paper accepted for publication in the journal Astrobiology, researchers challenge conventional assumptions about extraterrestrial life and explore the feasibility of life existing in structures created by living organisms themselves.
As researchers suggest, life-supporting conditions created solely by biological structures could indeed exist, making it entirely possible for some forms of life to thrive in space habitats vastly different from those on Earth.
According to astrophysicist Erik Zackrisson’s computer model, there could be about 70 quintillion planets in the universe. However, most of these planets are vastly different from Earth — they tend to be larger, older, and not suited for life. Only around 63 exoplanets have been found in their stars’ habitable zones, making Earth potentially one of the few life-sustaining planets. This could explain Fermi’s paradox — the puzzling lack of evidence for extraterrestrial life. While we continue searching, Earth might be truly special.
After reading the article, Harry gained more than 55 upvotes with this comment: “If life developing on Earth the way it has is 1 in a billion, then this would imply that there is life on at least a billion other planets (?)”
The prevailing belief among astronomers is that the number of planets should at least match the number of stars. With 100 billion galaxies in the universe, each containing about a billion trillion stars, there should be an equally vast number of exoplanets, including Earth-like worlds — in theory.

When considering the potential for life on exoplanets, scientists often focus on the habitable zone, the region around a star where conditions might allow liquid water to exist. However, new research suggests that this concept alone oversimplifies the dangers these planets face. It’s not just about being in the right place; it’s also about avoiding interstellar chaos.
While identifying exoplanets in the habitable zone is a crucial step in the search for extraterrestrial life, their environments can be treacherous. In a study soon to be published in The Astronomical Journal, researchers led by Tisyagupta Pyne from Visva-Bharati University highlight the threats lurking in dense stellar neighborhoods. Stellar flybys and catastrophic supernovae explosions have the power to disrupt entire planetary systems, stripping atmospheres or ejecting planets into interstellar space.
String theory could reshape our understanding of the Universe’s accelerating expansion and unlock the mysteries of dark energy.
The accelerating expansion of the Universe might not be just an unexplained phenomenon — according to a new proposal by theoretical physicists, it could be a fundamental feature woven into the very fabric of reality.
The researchers suggest that space is not an empty vacuum but that instead our whole Universe is a complex quantum object called the Glauber-Sudarshan state, where countless interacting strings are constantly born and disappear. This hypothesis breathes new life into string theory, which has long aimed to unify all the fundamental forces of nature.
