• Rethinking Cosmology • Universe Expansion May Not Be Uniform 8.4.2020 • A new study using galaxy clusters examines whether the Universe is "isotropic," or the same in all directions. • Galaxy clusters are enormous structures that astronomers can use to measure important cosmological properties. • The latest result uses X-ray data from Chandra and XMM-Newton of hundreds of galaxy clusters. • The cluster observations suggest that the Universe may be different depending on which way astronomers l

What is dark energy? Physicist Tessa Baker at the University of Portsmouth, UK, is at the forefront of the search for elusive dark matter, using some of cosmology’s most powerful tools, including the Laser Interferometer Gravitational-Wave Observatory (LIGO). By studying ripples in space-time sent out by the most extreme events in the cosmos, such as black hole mergers, experimentalists like Baker are beginning to test radical ideas: that dark energy might stem from hidden dimensions, elusive fi
