Wormhole echoes that may revolutionize Astrophysics
29 May 2018 8:30

The scientific collaborations LIGO and Virgo have detected gravitational waves from the fusion of two black holes, inaugurating a new era in the study of the cosmos. But what if those ripples of space-time had not produced by black holes, but by other exotic objects? A team of European physicists offer an alternative: wormholes, which can be traversed to appear in another universe.

What theoretical physics owes to Stephen Hawking
The legacy of a genius locked in a sick body

He never won a Nobel prize and lost several scientific wagers, but Stephen Hawking's contributions to the field of cosmology are undoubted. First-line physicists tell Sinc the ideas of the popular scientist that have helped us to better understand our universe, from black holes that emit radiation and vanish to quantum seeds that create galaxies or space-time curvatures that lead us to the Big Bang.

Pulsars with black holes could hold the ‘holy grail’ of gravity
3 December 2014 9:22

The intermittent light emitted by pulsars, the most precise timekeepers in the universe, allows scientists to verify Einstein’s theory of relativity, especially when these objects are paired up with another neutron star or white dwarf that interferes with their gravity. However, this theory could be analysed much more effectively if a pulsar with a black hole were found, except in two particular cases, according to researchers from Spain and India.

Recreación del sistema MWC 656
The discovery is published today in 'Nature'
Spanish researchers discover the first black hole orbiting a ‘spinning’ star
15 January 2014 13:30

Spanish scientists have discovered the first binary system ever known to consist of a black hole and a ‘spinning’ star – or more accurately, a Be-type star. Although predicted by theory, none had previously been found. The observations that led to the discovery were performed with the Liverpool and Mercator telescopes at the Observatorio del Roque de los Muchachos (Canary Islands, Spain).
