Black holes might not be dead-ends after all

A physical body might be able to cross a wormhole in spite of the extreme tidal forces, suggests a new study by Rubiera-Garcia, of Instituto de Astrofísica e Ciências do Espaço (IA), and his team. This result, published ...

Europe to launch satellites for Earth, Einstein

Europe is set to launch two satellites on Friday with very important missions: one will track environmental damage to Earth, while the other will test a mainstay of physics theory.

The hot problem of black hole firewalls

For the last four years, physicists studying the mathematical underpinnings of black holes have been wrestling with a strange idea: that black holes contain a region known as a "firewall," which utterly annihilates matter ...

Clocking the rotation rate of a supermassive black hole

A recent observational campaign involving more than two dozen optical telescopes and NASA's space based SWIFT X-ray telescope allowed a team of astronomers to measure very accurately the rotational rate of one of the most ...

Team simulates the expansion of the Universe

The Universe is constantly expanding. It changes, creating new structures that merge. But how does our Universe evolve? Physicists at the University of Geneva (UNIGE), Switzerland, have developed a new code of numerical simulations ...

Five-dimensional black hole could 'break' general relativity

Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, such an object could only exist in a universe with five ...
