Life could exist in parallel universes, astrophysicists say

Scientists have been trying to understand our place in the universe since time immemorial. This search prompted many ancient astronomers and philosophers to question whether we are the only living species in the cosmos.
And although we still have no idea how big the Universe is, where we are and what surrounds us, many believe that we are not alone in space.
But imagine for a moment that there could be other universes where intelligent life could exist.
There are chances that life could exist on planets located in parallel universes, according to two scientific studies published in the Royal Astronomical Society.
An international team of scientists has run computer simulations to build new universes in a variety of settings where dark energy has been a determining factor. To the surprise of the authors, it turned out that life can exist in more scenarios than the researchers had previously assumed.
According to scientists, dark energy is a mysterious and invisible force that exists in the “empty” spaces of the Universe. When gravity is compressed along with matter, dark energy, on the contrary, separates it. According to scientists, the second wins the space battle.
According to the latest estimates of the modern cosmological model, dark energy makes up approximately 69% of the total mass energy of the Universe. Experts explain that this amount is enough for the development of galaxies and life support. According to the researchers, if we lived in a universe with too much dark energy, then space would expand faster than galaxies could form.
Conversely, if there were no shortage of dark energy, gravity would cause galaxies to collapse within themselves before they could fully form. It looks like some kind of cosmic balance.
Through a series of experiments and simulations, an international team of scientists from England, Australia and the Netherlands used a program called Evolution and Collision of Galaxies and Their Environments to simulate the birth, life and eventual death of various hypothetical universes.
In every simulation conducted by experts, the amount of dark energy in the universe has been adjusted upwards from zero to several hundred times.
Scientists have found that even in universes where the amount of dark energy is 300 times greater than ours, life still continued to exist.
“The simulations have shown that the accelerated expansion caused by dark energy has little to no effect on the birth of stars and therefore on the origin of life,” said study co-author Pascal Elahi, a researcher at the University of Western Australia.
“We wonder how much dark energy can be before life becomes impossible. Our simulations have shown that the accelerated expansion caused by dark energy has little to no effect on the birth of stars and, therefore, on the origin of life. A hundred times may not be enough to create a lifeless universe.”
Based on recent research, if we were part of the Multiverse, we would expect to see much more dark energy than we currently have, about 50 times what we see in our Universe.
Professor Richard Bauer of the Institute for Computational Cosmology at Durham University said:
“Star formation in the universe is a battle between the pull of gravity and the repulsion of dark energy. In our simulations, we found that universes with much more dark energy than we currently have can form stars perfectly.”
“So why is there so little dark energy in our universe? I think we should be looking for a new law of physics to explain this strange property of our universe.”
In short, parallel universes, which most likely also exist, are filled with life, just like our universe. The only question remains what kind of life exists there.

Former US Air Force fighter pilot: UFOs use Star Trek-style warp drive

A former US Air Force fighter pilot asserts that he has deciphered
the method behind the extraordinary maneuvers of UFOs, reports dailystar.co.uk.
Over
the past two decades, numerous military encounters with these enigmatic
crafts have been reported, prompting a significant investigation by the
Pentagon.
One of the most renowned sightings occurred during the
USS Nimitz encounter, where fighter pilots witnessed a UFO descending
from 28,000 feet to just above sea level in less than a second.
This
astonishing movement would imply that the craft reached a staggering
speed of 19,000 miles per hour, a velocity that would be fatal to any
human pilot.
According
to Chris Lehto, a former USAF pilot, the craft exhibits two key
characteristics: it moves without inertia, essentially lacking weight,
and it accelerates at an incredibly rapid pace without affecting its
surroundings.

Chris
believes that the explanation lies within a technology that seems
straight out of science fiction. He proposes that the answer to the UFO
enigma lies in the Alcubierre Drive, a theoretical interstellar engine
conceptualized by Mexican physicist Miguel Alcubierre in 1994.
The
Alcubierre Drive employs a form of “space warp” technology, reminiscent
of what has been depicted in episodes of Star Trek. By bending space, a
craft inside a “warp bubble” could potentially travel at or even
surpass the speed of light without violating the known laws of physics.
While
the Alcubierre Drive remains a hypothetical concept with challenges to
overcome, Chris notes that the required energy is no longer believed to
be unattainably large.
Patents
filed with the US patent office outline the potential workings of the
drive, as well as another groundbreaking technology theorized by
American aerospace engineer Salvatore Pais.
Pais suggests that
high-powered rotating magnets could theoretically eliminate an object’s
inertia, and he has filed a patent for a starship based on this
principle.
However, Chris maintains skepticism regarding Pais’
theory. He explains that while Pais’s patent applications for the US
Navy attracted attention for their potential energy-related
applications, doubts have been raised about their feasibility. There is
speculation that they may be scams, pseudoscience, or disinformation
intended to mislead adversaries of the United States.
Alternatively,
rival theories propose that the “Tic Tac” UFO is a classified Pentagon
project testing similar advanced technologies discussed by Chris.

A Mysterious Earth-Like Planet Has Just Appeared in Our Solar System, Scientists Say

Scientists say they have found evidence of a new Earth-like
planet that has suddenly appeared in our Solar System and is orbiting
the Sun.
Physicists, including those from the National Astronomical Observatory
of Japan, said the planet is likely to be the mysterious ‘Planet Nine’
that was hypothesised to exist in the far outer edges of the Solar
System.
Several studies in the past have suggested there is likely an
undiscovered planet beyond the Kuiper Belt – a stellar disk of materials
such as asteroids, space rocks, comets around the Sun in the outer
Solar System past the orbit of Neptune.
Independent.co.uk reports: In the new research, published recently in The Astronomical Journal, scientists
found that some of the objects in the Kuiper Belt behave in a way
indicative of the presence of a small planet among them.
One such object, they said, is about 500 astronomical units (AU) from
the Sun, where 1 AU is the distance between the Sun and the Earth.
In comparison Neptune is at a distance of 30 AUs from the Sun.
Some of these were also found to have “odd” orbits suggesting they
are being pull by the gravity of a cosmic entity larger than those that
typically influence such objects.
Computer simulations run by the scientists indicate that the most
likely explanation for the observations was another hidden planet in the
Kuiper Belt.
“We predict the existence of an Earth-like planet,” researchers wrote in the study.
“It is plausible that a primordial planetary body could survive in
the distant Kuiper Belt as a Kuiper Belt planet (KBP), as many such
bodies existed in the early solar system,” they added.
If such a planet exists, researchers say it would have a mass about
1.5 to 3 times that of Earth with an inclination of about 30 degrees.
They say the theorised planet’s orbit would likely place it between 250 and 500 AU from the Sun.
Researchers say the discovery of such a planet close to the Kuiper
Belt can unravel new constraints on planet formation and evolution.
“In conclusion, the results of the KBP scenario support the existence
of a yet-undiscovered planet in the far outer solar system,” scientists
noted.
