A year after scientists witnessed the “mind-boggling” collision of two giant black holes, they now suspect the event actually involved two even more bizarre objects – and could answer one of the biggest mysteries about our universe.
What could be weirder than black holes?
Astronomers have long suspected that our universe contains vast quantities of a substance unlike anything observed on Earth.
Studies of galaxies hint at the presence of invisible “dark matter” lurking between the visible stars, revealing its presence through its gravitational pull.
Quite what this dark matter consists of is one of the biggest of all cosmic mysteries. Now an international team of scientists think they may have an answer.
Merger of Two Boson Stars Could Explain Existence of Dark Matter

An international research team has now demonstrated that the heaviest collision of black holes to be ever visualized and created by the gravitational-wave GW190521 could be more mysterious than previously believed that is, the merger of a pair of boson stars.

The new study would be the first proof of the presence of these theoretical objects that represent one of the key candidates to create dark matter, which constitutes 27% of the Universe.
Food systems, sustainability and health Expanding the Scope of Research in Planetary Health in Europe webinar series
Funded by the ISGlobal Severo Ochoa Strategic Programme, the Barcelona Institute for Global Health (ISGlobal) in collaboration with the London School of Hygiene & Tropical Medicine (LSHTM) Centre on Climate Change & Planetary Health and the Finnish Institute for Health and Welfare (THL), is hosting the series of 5 weekly webinars: “Expanding the scope of research in planetary health in Europe”.
The programme is aimed at strengthening the field of planetary health, particularly within Europe, by bringing together stakeholders from academia, government, and civil society. The initiative builds on previous activities including the EU meeting “The Europe that Protects: Safeguarding our Planet, Safeguarding our Health” held in Dec 2020 in Helsinki, as well as the “Horizon 2020 HERA Research agenda for the Environment, Climate & Health 2020-20
Lessons Learned in MLC Continue to Influence Neil Anderson â03
The travel opportunities he received through the University of Maineâs Modern Languages and Classics Department helped put Neil Anderson, â03, on the path to success by allowing him to hone his language skills in French and Spanish and prompting him to delve further into his studies.
Anderson, who graduated from UMaine with a bachelorâs degree in Spanish and a minor in French, went on to earn a masterâs degree in Spanish from Middlebury College in Vermont and now is a Ph.D. student in Spanish at the University of North Carolina at Chapel Hill.
The right to health versus the right to vote. The Catalan elections called for February 14 with the third wave of the pandemic in full swing, once again put on the table the collision of fundamental rights experienced by the Basque and Galician governments last year, when they had to choose to postpone the elections from April to July .
A mirror before which the Government and the Catalan parties are now looking. The Executive is committed to setting the new date in the second half of May and the PSC is the only formation that defends maintaining the current calendar. The decision will be made tomorrow Friday.
