The early universe may chirp about unknown physics. A University of Helsinki research team has demonstrated how an early universe phase transition will lead to gravitational wave signals potentially visible in the upcoming satellite missions. The research results were recently published in the journal Physical Review Letters.
Phase transitions, such as the boiling of water or the melting of a metal, are commonplace but fascinating phenomena that spur surprises decades after decades...

Black holes colliding, gravitational waves riding through space-time – and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers have now found that LISA could also shed light on the elusive dark matter particle.
The Laser Interferometer Space Antenna (LISA) will enable astrophysicists to observe gravitational waves emitted by black holes as they collide with or capture other black holes. LISA will consist of three spacecraft orbiting the sun in a constant triangle formation...
