There are no black holes?

Posted by baffa on Mar 06, 2014 - 11:01 AM
Stephen Hawking has proposed a new solution to the black-hole firewall paradox, a tantalizingly simple solution: black holes simply do not have an event horizon.

The Closest Star System Found in a Century

Posted by baffa on Mar 12, 2013 - 09:30 AM
A pair of newly discovered stars (WISE J104915.57-531906) is the third-closest star system to the Sun, according to a paper that will be published in Astrophysical Journal Letters

Earth-mass exoplanet orbiting Alpha Centauri B

Posted by baffa on Oct 17, 2012 - 08:16 AM
European astronomers have discovered a planet with about the mass of the Earth orbiting Alpha Centauri B, the nearest star system. It is also the lightest exoplanet ever discovered around a star like the Sun. The planet was detected using the HARPS instrument on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile.

Ma et al. found to a high degree of confidence that entanglement can be produced a posteriori, after the entangled particles have been measured and may no longer exist.

A lot of rocky Planets

Posted by baffa on Mar 28, 2012 - 12:10 PM
A new result from ESO’s HARPS planet finder shows that rocky planets not much bigger than Earth are very common in the habitable zones around red dwarf. The team estimates that there are tens of billions of such planets in our galaxy, and probably about one hundred in the Sun’s neighbourhood.

Evidence For Magnetic Monopoles

Posted by baffa on Sep 22, 2009 - 04:38 PM
It seems magnetic monopoles have been detected at low temperatures in "Dirac strings" within a single crystal of Dysprosium Titanate. Theoretical work had shown that monopoles probably exist, and they have been measured indirectly. But two papers (1, 2) offer the first direct evidence of the monopole's effects on the spin-ice material.
