Life could exist in parallel universes, astrophysicists say

Published

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.

‘October Surprise’: Russia To Launch Nukes in Space

Published

The ‘national security threat’ announced on Wednesday is
about Russia planning to launch nuclear weapons in space, causing some
to speculate whether it’s really an election year ploy.

The panic began when House Intelligence Committee Chair Mike Turner
(R-Ohio) asked President Biden to declassify information about a
“serious national security threat”.

Modernity.news reports: The weapon would reportedly be designed to be used to take out satellites.

Speaker Mike Johnson (R-La.) responded by telling reporters he wanted “to assure the American people, there is no need for public alarm.”

The big, scary threat is serious business and involves a space-based nuke controlled by evil dictator Putin, but it’s also “not an immediate crisis,” according to what three members of the U.S. House Intelligence Committee have told Politico.

Okay, then. Just for election season, is it?

Zero Hedge reports: “So, the question is – was this:

a) a distraction from Biden’s broken brain, or

2) a last desperate attempt to get more funding for anything-but-the-US-border, or

iii) a path to pitching Putin as the uber-bad-guy again after his interview with Tucker Carlson.”

Just by coincidence, Mike Turner recently returned from Ukraine having lobbied for billions more in weapons and aid for Zelensky’s government.

Some questioned the timing, suggesting it might all be a deep state plot to keep American voters afraid when they hit the ballot box.

Speculation will now rage as to whether this is “the event,” real or imagined, that billionaires and elitists the world over have been building underground survival bunkers in preparation for.

Earth has built-in protection from asteroids

Published

Asteroids are not just wandering space rocks, but a potential threat
to Earth. But what if the Earth already has its own built-in defenses
against them? Recent research published on the preprint server arXiv puts forward an unusual theory: Earth’s gravitational forces may serve as its secret shield against asteroids.

Our
planet uses powerful gravitational interactions with other celestial
bodies to break apart asteroids that approach it. These tidal forces,
akin to those that explain Earth’s tides caused by the Moon, can be so
intense that objects undergo tidal disruption, causing them to be torn
apart.

Observations of fragments of Comet Shoemaker-Levy 9 after
its collision with Jupiter in 1994 provided the first confirmation of
this phenomenon. However, for decades astronomers have been looking for
evidence that Earth or other terrestrial planets could have a similar
effect on asteroids and comets.

Planetary scientist Mikael Granvik
from the Swedish University of Technology, Luleå, led the research that
came closer to solving the above phenomenon.

His
discovery is linked to the search for gravitationally disrupted
near-Earth asteroids (NEAS), and provides compelling evidence that our
planet’s gravitational forces are not just an abstract concept, but a
factor capable of breaking asteroids into small pieces.

Based on
modeling of asteroid trajectories, Grunwick and colleague Kevin Walsh of
the Southwest Research Institute found that collisions with rocky
planets can cause asteroids to lose a significant portion of their mass,
turning them into debris streams.

New data shows that small
asteroid fragments, while not posing a threat to life on the planet, may
nevertheless increase the likelihood of local collisions like those
that occurred in Tunguska and Chelyabinsk.

Granwick assures that
asteroids smaller than 1 km in diameter are not a critical threat, but
increase the likelihood of incidents. However, it is worth remembering
the additional risks that may arise due to the formation of new debris
clouds.
