We know that our Universe is very vast and to figure out to what extent it has spread and how it is created is still a question mark. But recently, CERN scientists have revealed a surprising thing. They have found out that the universe inside which we are dwelling actually should not exist. Yes, according to them, the existence of Universe is not possible if the scientific theory, research, and experiments are considered.
The CERN scientists got those findings from the BASE (Baryon Antibaryon Symmetry Experiment) which is considered as the most precise experiment on antiprotons. Through the experiment, the scientists have discovered a symmetry in nature which they say shouldn’t be possible. Actually, everybody thinks that Universe was created from Big Bang’s first matter. But the recent research claims that particles and antiparticles destroy one another when they come in contact with each other if they both have equal measures. This means that particles are n symmetry and the Universe would not exist – at least not in the form we see it today. Scientists argued that, for Universe to form, there should be an imbalance (at least of the tiniest fraction), between particles and antiparticles.
First author Christian Smorra, from Japan’s RIKEN institute, said in a statement that all of their observations revealed a complete symmetry between matter and antimatter, which is why the Universe should not exist. “All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist,” explained Christian Smorra, first author of the study. “An asymmetry must exist here somewhere but we simply do not understand where the difference is. What is the source of the symmetry break?”
For the research, the CERN scientists used antiprotons that were isolated in 2015. The antiprotons were measured by interacting two straps that use electrical as well as magnetic fields to capture them. “We thus used a method developed at Mainz University that created higher precision in the measurements,” explained Ulmer. “The measurement of antiprotons was extremely difficult and we had been working on it for ten years. The final breakthrough came with the revolutionary idea of performing the measurement with two particles.”
The scientists successfully managed to measure the magnetic force of the antiproton to a level that is 350 times more precise than ever before. So this high level of precision would have definitely detected any slight imbalance between protons and antiprotons. But scientist found out that there was symmetry between protons and antiprotons. Stefan Ulmer spokesperson of the BASE group said that at first, they were facing difficulty in measuring the antiprotons and their magnetic force. After 10 years of rigorous research, finally, they came out with the breakthrough idea of performing the measurement with two particles.
Now, scientists want to measure protons and antiprotons with even higher measurement techniques so as to improve on their latest findings. They believe that there must be an asymmetry somewhere which they could not figure out and want more thorough research on it.
“Further improvements in the measurement precision of the antiproton magnetic moment using our method are possible,” they wrote in their paper. “We expect that with a technically revised apparatus, including improved magnetic shielding, an improved resistive cooling system for the cyclotron mode with lower temperature, and a precision trap with a more homogeneous magnetic field, it will be possible to achieve a tenfold improvement in the limit on… interactions from proton/antiproton magnetic moment comparisons in the future.”
As per Wiki, The Universe is all of space and time[a] and their contents,[12] including planets, stars, galaxies, and all other forms of matterand energy. While the spatial size of the entire Universe is still unknown,[6] it is possible to measure the observable universe.
The earliest scientific models of the Universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the centre of the Universe.[13][14] Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the centre of the Solar System. In developing the law of universal gravitation, Sir Isaac Newton built upon Copernicus’s work as well as observations by Tycho Brahe and Johannes Kepler’s laws of planetary motion.
Further observational improvements led to the realization that our Solar System is located in the Milky Way galaxy, which is one of many galaxies in the Universe. It is assumed that galaxies are distributed uniformly and the same in all directions, meaning that the Universe has neither an edge nor a center. Discoveries in the early 20th century have suggested that the Universe had a beginning and that it is expanding[15] at an increasing rate.[16] Roughly eighty percent of mass in the Universe appears to exist in an unknown form called dark matter which cannot be directly observed.[17]
The Big Bang theory is the prevailing cosmological description of the development of the Universe. Under this theory, space and time emerged together 13.799±0.021 billion years ago[2] with a fixed amount of energy and matter that has become less dense as the Universe has expanded. After the initial expansion, the Universe cooled, allowing the first subatomic particles to form and then simple atoms. Giant clouds later merged through gravity to form galaxies, stars, and everything else seen today. It is possible to see objects that are now further away than 13.799 billion light-years because space itself has expanded. This means that objects which are now 46 billion light years away can still be seen in their distant past, because at that time they were much closer to us.
There are many competing hypotheses about the ultimate fate of the universe and about what, if anything, preceded the Big Bang, while other physicists and philosophers refuse to speculate, doubting that information about prior states will ever be accessible. Some physicists have suggested various multiverse hypotheses, in which the Universe might be one among many universes that likewise exist.
