The Nobel Prize in Physics this year was awarded to Roger Penrose(1/2) "for the discovery that black hole formation is a robust prediction of the general theory of relativity " and the other half to Reinhard Genzel, and Andrea Ghez "or the discovery of a supermassive compact object at the center of our galaxy."

Zeno's Paradox: Would Physics be able to solve it?

/

Zeno of Elea (c. 495 – c. 430 BC) was a pre-Socratic Greek philosopher of Magna Graecia and a member of the Eleactic School founded by Parmenides. Aristotle called him the inventor of the dialectic He is best known for his Paradoxes, which Bertrand Russell described as "immeasurably subtle and profound".

Saturn Rings

We determined Saturn’s gravitational field by reconstruction of Cassini’s trajectory during the Grand Finale, using a coherent microwave link between Earth tracking stations and the spacecraft. Range-rate measurements were obtained from the Doppler shift of a carrier signal sent from the ground at 7.2 GHz (X-band) and retransmitted back to Earth by Cassini’s onboard transponder at 8.4 GHz. An auxiliary downlink at Ka-band (32.5 GHz) was also recorded.

Galaxy clusters are among the largest structures in the universe, containing thousands of individual galaxies, dark matter and hot gas. At the heart of the Ophiuchus cluster there is a large galaxy that contains a supermassive black hole with a mass equivalent to 10 millions suns.

Deconstructing Schrödinger's cat

///
2 mins read

The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the years, but no approach has been universally accepted. Now, however, theoretical physicist Franck Laloë from Laboratoire Kastler Brossel (ENS-Université PSL) in Paris has proposed a new interpretation that could explain many features of the paradox. He sets out a model of this possible theory in a new paper in EPJ D.

Image: 'Pale Blue Dot' revisited

//
5 mins read

The picture, named "The Pale Blue Dot" was obtained on 14th February, 1990, moments before the camera and the several other instruments of the Voyager were powered off for conservation of battery, since the probe wouldn't make a close flyby past any other objects during their lifetime.
