SXS—Simulating eXtreme Spacetimes—is an ongoing scientific collaboration that has been generating simulations of dramatic events in space, particularly mergers of binary black hole systems, for several decades. Recently, ...
Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with current instruments.
Since the early 20th century, scientists have gathered compelling evidence that the universe is expanding at an accelerating rate. This acceleration is attributed to what is known as dark energy—a fundamental property of ...
The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion years from now, it will ...
For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study suggests they might not exist at all. Instead, what we perceive as dark matter and dark energy could ...
Nobel laureate Dr. George Smoot, who conducted groundbreaking research into the origins of the universe during a long career at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory, has died, ...
Plasma is a state of matter that emerges when a gas is heated to sufficiently high temperatures, prompting some electrons to become free from atoms. This state of matter has been the focus of many astrophysical studies, as ...
For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time.
The consortium running the European Space Agency's (ESA) Euclid mission has published the most extensive simulation of the cosmos to date. The modeling was based on algorithms developed by UZH professor Joachim Stadel.
Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a grand, cosmological scale, though disproving them can be particularly hard.
