Our understanding of the universe has come a long way in the past century, but there is still a lot we don’t know about the Universe.
From the theory of parallel universes to the idea that our galaxy is shaped like a sphere, here are some of the most puzzling theories scientists have proposed to help explain the structure of our galaxy. space and time.
Back in May 2020, Nasa scientists hinted that they had found evidence of a strange parallel universe where time runs backwards.
This discovery was apparently made while experts were conducting an experiment in Antarctica to detect cosmic rays.
The concept of a “twin universe” has been around for decades, but new research has found particles that may just be from another realm that were also born in the Big Bang,
Scientists used a giant airship to carry NASA’s Antarctic Impulse Transient Antenna (ANITA) high above the frozen wastes of Antarctica.
It reached a height where the frigid air provided a perfect environment with little or no radio noise to falsify any detection, reports Daily Star.
There is always a “wind” of high-energy particles coming from space, some of which are a million times more powerful than anything created on Earth.

That means only high-energy particles that are “coming down” from space can be detected, but ANITA has apparently detected heavier particles that appear to be “coming up” from Earth.
That means these particles are indeed traveling back in time, which is considered possible evidence of a parallel universe.
ANITA Principal Investigator, Peter Gorham, of the University of Hawaii, suggested the only way a particle could behave that way is if it mutated into another type of particle before passing through the Earth and then orbiting. come back.
Gorham, lead author of the Cornell University paper describing the strange phenomenon, noted that he and his fellow researchers had witnessed a number of “impossible events.”
“Not everyone is comfortable with this hypothesis,” he said.
The simplest explanation is that by the time of the Big Bang 13.8 billion years ago, two universes had formed – ours and one where time went back.
However, some believe the results may be due to a scientific glitch.
Pat Scott, a particle phenomenology at the University of Queensland, tell CNET: “Nothing necessarily makes it detect a parallel universe.”
The universe is not flat
According to a recent study, the shape of the known universe may actually be a curved and closed sphere.
If true, that means everything we think we know about the universe is wrong – because our theory is based on the assumption it is flat.
A 2019 study analyzed cosmic microwave background data collected by the European Space Agency’s Planck satellite.
This cosmic microwave background is thought to be a faint echo of the Big Bang that created the universe.
Research shows that gravity seems to warp microwaves – suggesting a closed universe.
If the universe is closed, it means that if you have gone far enough, you will eventually return to where you started.
According to this theory, it is possible that the universe is still expanding when researchers describe it as like an inflating balloon.
The study was published in the journal Natural Astronomy.
The researchers say their discovery could represent “a possible crisis for cosmology”.
However, some astronomers have supported the idea, saying that there is not enough evidence to support their outlandish claims.
Big bang ‘never happened’
The Big Bang theory is the most widely accepted explanation for how our universe began – but experts have challenged the theory.
In 2017, Brazilian physicist Juliano Cesar Silva Neves announced the unprecedented Big Bang 13.8 billion years ago saying that the universe may have preceded a period of contraction.
The Big Bang theory states that the universe started with a small singularity then stretched and expanded over billions of years into the universe we know today.
But Neves believed in the Big Bounce theory, in which the universe itself collapsed to give way to the eternal succession of universes.
The researcher, from the Institute of Mathematics, Statistics & Computational Sciences of the University of Campinas in Sao Paulo, said: “To measure the rate at which the universe is expanding with standard cosmology, the model includes a The big bang, a mathematical function used that depends only on cosmological time.
“Removing the singularity or the Big Bang would bring the universe back to the theoretical stage of cosmology.
“The absence of a singularity at the beginning of spacetime opens up the possibility that vestiges of a previous period of contraction may impede the phase change and may remain with us in the opening.” continuum of the Universe.”
In a study published in the journal General Relativity and Gravity, Neves explores the behavior of “regular” black holes.
According to him, a black hole is not defined by a singularity, but rather a point of infinite density and the strongest gravitational force that has ever existed.
“Outside the event horizon of a typical black hole, there are no major changes, but inside it, the changes lie deep within,” he said.
“There is another spacetime to avoid the formation of a singularity.”
Neves says the hypothesis can be tested by “looking for traces of events in a contraction phase that may still be in an ongoing expansion phase”
The physicist added: “Candidates include black hole remnants from an earlier stage of cosmic contraction that may have survived the bounce.”
