ANITA Experiment

ANITA Experiment

Antarctic Impulsive Transient Antenna (ANITA) experiment has been designed to study ultra-high-energy cosmic neutrinos by detecting the radio pulses emitted by their interactions with the Antarctic ice sheet. This is to be accomplished using an array of radio antennas suspended from a helium balloon flying approximately at a height of about 37,000 meters.

Usually particles and photons interact at high energies with microwave background photons — making them unable to propagate. None of the known Standard Model particles should have been able to fly all the way through the

Reverse IS Possible

It is evident that our universe barely contains any anti matter but we know( theoritically) that during the big bang matter formation had to be accompanied by anti-matter formation. (Also the reverse process is possible i.e when matter and anti matter annihilate energy is produced) .

So th...

Anti Universe

Anti Universe

Quantum mechanics doesn’t predict a single solid result when undergoing an observation. On the contrary, it predicts a number of different possible outcomes. Similarly, entropy is a measure of the number of possible arrangements the atoms in a system can have. And when trying to take both these i...

Earth and burst out the other side at such high energies, but that’s what ANITA seemed to be detecting. These findings can’t be explained by our current understanding of physics. Some physicists believe ANITA might have detected the sterile neutrinos that are directly coming from the parallel uni...

The beam is measured — the change in the measured intensity and composition of the beam is used to provide information on the properties of neutrinos.

Scientific concepts pass through three stages before they’re accepted as reality. The first stage involves being ignored — nobody take these...

It’ll take time and detection of unknown particles, the right handed neutrinos, especially the sterile neutrino to prove the theory right.

Recent Discovery

In 2020, Neil Turock of the Perimeter Institute in Canada says, ‘when our big bang expansion of a matter universe happened, at the same time it created a collapsing antimatter universe containing this unwanted antimatter to be bound up in a singularity and hidden from us.’ He further says the ant...

Electric fields can create particle-anti-particle pairs out of the vacuum. So his theory is built on the idea that it’s possible to drag the universe out of nothing. The implication of this model is that there would be two sides to universe — matter as well as anti-matter. He further says that co...

To preserve the CPT symmetry throughout the cosmos, there must be a mirror-image cosmos that just balances out our own. Not only this universe would have all opposite charges than we have, be flipped in the mirror, but anti-particles will run backward in time. Scientists predict that particles mo...

— These are also known by the name inert neutrinos. These are hypothetical particles that are believed to not interact via any other fundamental interaction of the standard model except gravity. These are the neutrinos considered right-handed . For a particle regarded as a dark matter candidate,...

T2K Experiment

T2K is a neutrino experiment designed to investigate how neutrinos change from one type or flavour to another as they travel (neutrino oscillations). An intense beam of muon neutrinos is generated at the J-PARC nuclear physics site on the East coast of Japan and directed across the country to the...

What Will Happen When Anti-particles And Particles Meet?

So,in a nutshell, the discovery of positron proved Dirac’s theory right.We know that every particle has an exact antiparticle too,with which it would finally annihilate.It is now known that all the so-called elementary particles have antimatter counterparts.As per, E=mc²,the collision be...

to these, some stable ghostlike particles called electron neutrino, muon neutrino, and tau neutrinos have been discovered — they don’t interact with ordinary matter.

The concept is beautifully stated in Stephen Hawking’s, Our Brief History Of Time, where he says, “There could be whole antiworlds and antipeople made up of antiparticles. If you meet your antiself, don’t shake hands! You would both vanish in a great flash of light.”

To comply with the theory of dark matter, scientists believe there exists not just one type of sterile neutrino but three such types.

In 2018, MiniBooNE experiment, reported a stronger neutrino oscillation signal — pointing towards the possibility of finding sterile neutrinos. But it couldn...

The answer to this question is equally interesting. Scientists say that most of the particles created in the early universe were annihilated by anti-particles. But, some of these (one in a billion) particles had no matching anti-particles. So these particles survived to form the matter we observe...

CPT symmetry

It’s the most important part of this article as the genesis of anti-universe theory has basis in it. We know our all the laws of physics took birth in symmetries.

Dark matter is the most mysterious thing in the entire universe in a way how it affects ordinary matter. CPT symmetry is the only theory that explains dark matter more than any other theory. Some scientists believe the presence of fourth type of neutrino(undetected) — often termed a steri...

First of all, let’s understand the neutrino as these forms the basis for understanding the anti-universe. We’ll learn how certain neutrinos’ discovery could provide evidence of the anti-universe theory.
