How can the behavior of elementary particles and the structure of the entire universe be described using the same mathematical concepts? This question is at the heart of recent work by the mathematicians Claudia Fevola from ...
A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly Notices of the Royal Astronomical ...
Understanding the early universe is a foundational goal in space science. We're driven to understand nature and how it evolved from a super-heated plasma after the Big Bang to the structured cosmos we see around us today. ...
Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What is the particle nature ...
It is now understood that all known matter, i.e., studied by science and harnessed by technology, constitutes only 5% of the content of the universe. The rest is composed of two unknown components: dark matter (about 27%) ...
Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had other roles to play ...
Looking up at the night sky, it may seem our cosmic neighborhood is packed full of planets, stars and galaxies. But scientists have long suggested there may be far fewer galaxies in our cosmic surroundings than expected.
Throughout cosmic evolution, although dwarf galaxies are individually small, they are numerous and serve as the fundamental building blocks shaping the large-scale structure of today's universe. These small galaxies are also ...
It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the dramatic explosion of a particular kind of white dwarf. In 1998, they announced their surprising results: ...
Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest elements were created ...
