The multiverse: How we're tackling the challenges facing the theory

The idea of a multiverse consisting of "parallel universes" is a popular science fiction trope, recently explored in the Oscar-winning movie "Everything Everywhere All At Once." However, it is within the realm of scientific ...

Evidence for the existence of a deeply bound dibaryon, built entirely from beauty quarks

Dibaryons are the subatomic particles made of two baryons. Their formations through baryon-baryon interactions play a fundamental role in big-bang nucleosynthesis, in nuclear reactions including those within stellar environments, ...

The multiverse: Our universe is suspiciously unlikely to exist—unless it is one of many, says physicist

It's easy to envisage other universes, governed by slightly different laws of physics, in which no intelligent life, nor indeed any kind of organized complex systems, could arise. Should we therefore be surprised that a universe ...

In search of the invisible galaxy

A mysterious and very distant object, in a universe as it was 'just' two billion years after the Big Bang, hides from even the most advanced instruments. Its features have finally been described by a team from SISSA in a ...

Hydrodynamical simulations for the common-envelope wind model for Type Ia supernovae

Ph.D. candidate Cui Yingzhen and Prof. Meng Xiangcun from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) performed hydrodynamic simulations on the common-envelope wind model of Type Ia supernovae (SNe Ia), ...

Can cosmic inflation be ruled out?

A team of astrophysicists say that cosmic inflation—a point in the universe's infancy when space-time expanded exponentially, and what physicists really refer to when they talk about the "Big Bang"—can in principle be ...

African ubuntu can deepen how research is done

Many academic studies have been centered on Western theories and methodologies for a long time. This approach to research is broadly defined as "universalist." It assumes that "one-size-fits-all" and set norms can be applied ...

Higgs10: Inventing the future of Higgs research

In 1975, three CERN theorists, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos, undertook the first comprehensive study of the collider phenomenology of the Higgs boson. Almost 40 years later, it was discovered at the ...

Using holograms to illuminate de Sitter space

Our understanding of the universe may not be expanding as much as the universe itself. In some cases, our theories about cosmic inflation may feel as if they are deflating into a black hole.

Putting the theory of special relativity into practice, by counting galaxies

Scientists who study the cosmos have a favorite philosophy known as the "mediocrity principle," which, in essence, suggests that there's really nothing special about Earth, the sun or the Milky Way galaxy compared to the ...
