If you accept cosmic inflation and quantum physics, there’s no way out. The Multiverse is real.

But no other new particles have materialized at the LHC, leaving open many mysteries about the universe that the Standard Model doesn’t address. A debate has ensued over whether to build an even more enormous successor to the LHC — a proposed machine 100 kilometers in circumference, possibly in Switzerland or China — to continue the search for new physics.

Physicists say there’s much we can still learn from the Higgs boson itself. What’s known is that the particle’s existence confirms a 55-year-old theory about the origin of mass in the universe. Its discovery won the 2013 Nobel Prize for Peter Higgs and François Englert, two of six theorists who proposed this mass-generating mechanism in the 1960s. The mechanism involves a field permeating all of space. The Higgs particle is a ripple, or quantum fluctuation, in this Higgs field. Because quantum mechanics tangles up the particles and fields of nature, the presence of the Higgs field spills over into other quantum fields; it’s this coupling that gives their associated particles mass.

But physicists understand little about the omnipresent Higgs field, or the fateful moment in the early universe when it suddenly shifted from having zero value everywhere (or in other words, not existing) into its current, uniformly valued state. That shift, or “symmetry-breaking” event, instantly rendered quarks, electrons and many other fundamental particles massive, which led them to form atoms and all the other structures seen in the cosmos.

A new 50p coin will memorialise Stephen Hawking, who died last year, while paying respect to his groundbreaking research on black holes.

The age our universe is about 3.8 billion years which was formed after big bang. But we discovered a star named HD 140283 found to be older than the universe.

The concept of antimatter has delighted sci-fi fans for years, but it also poses a real question for physicists. Mathematically speaking, it makes sense that for every type of particle in our universe there exists a corresponding antiparticle which is the same but with the opposite charge — so to correspond with the electron, for example, there should be an antielectron, also known as a positron. When antimatter and matter come into contact, they both destroy each other in a flash of energy.

When the Big Bang happened, it should have created equal amounts of both matter and antimatter. And yet matter is everywhere and there is hardly any antimatter in our universe today. Why is that?

A new experiment from CERN, the European Organization for Nuclear Research, has been tackling the question by looking at how matter and antimatter could react differently to Earth’s gravitational field. Physicists think that antimatter could fall at a different rate than matter, which would help to explain why it is less prevalent. But in order to test this, they need to create antimatter particles such as positronium atoms. These are pairs of one electron and one positron, but they only live for a fraction of a second — 142 nanoseconds to be exact — so there isn’t enough time to perform experiments on them.

A new method for analysing the entanglement of scrambled particles could tell us how the Universe still keeps track of information contained by particles that disappear into black holes. It won’t get our quantum information back, but it might at least tell us what happened to it.

Physicists Beni Yoshida from the Perimeter Institute in Canada and Norman Yao from the University of California, Berkeley, have proposed a way to distinguish scrambled quantum information from the noise of meaningless chaos.

While the concept promises a bunch of potential applications in the emerging field of quantum technology, it’s in understanding what’s going on inside the Universe’s most paradoxical places that it might have its biggest pay-off.

Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these bizarre objects.

As more time passes since the Big Bang, more of the Universe comes into view. But how much?

How do you find something you can’t see? Japanese astronomers have hunted a hidden black hole by observing the movement of a cloud of gas it is consuming, located 25,000 light-years away from Earth. This is the first intermediate-sized black hole ever found, giving clues to how black holes merge and grow.
