Earth-sized world 'around nearest star'
The nearest habitable world beyond our Solar System might be right on our doorstep - astronomically speaking.

Scientists say their investigations of the closest star, Proxima Centauri, show it to have an Earth-sized planet orbiting about it.

What is more, this rocky globe is moving in a zone that would make liquid water on its surface a possibility.

Proxima is 40 trillion km away and would take a spacecraft using current technology thousands of years to reach.

Despre stiintele sociale, statistica, replicabilitate, peer reviews etc.:

Bine, oricum n-are treaba cu Romania (dupa ce am prins veste de cum se face treaba - si nu ma refer doar la faptul ca mare parte din "cadre" sunt din fosta/revolutionara/securitatea de acum - eu actualmente sustin si salut decizia lui Ceausescu de a desfiinta educatia in psihologie... pare-mi-se ca e singura optiune si acum, in 2016... cine isi imagineaza ca romania a intrat in secolul XX e un fraier) dar este o citeala buna.

My fucking nigger. Cat de amazing ar fi sa vedem oameni plecati pe Marte in timpul vietii noastre? Daca e ceva ce astept cu nerabdare sa se intample in urmatoarele zeci de ani, asta e.

Sper doar ca bravii colonisti martieni s nu dea de niste croncobauri subterani care sa ii masacreze pe-acolo.

Elon Musk plans to get humans to Uranus in six years

Pe legea mea, cat am fost de amuzant.

Saturn e o bila de gaz care nici macar nu prea are sateliti interesanti, apart from Titan iirc. Jupiter are insa niste sateliti pe care s-ar afla apa in cantitati mari, dar tot Marte (probabil cu Luna ca oprire intermediara) ramane cea mai realista optiune pentru ~100 de ani.

Si Enceladus? Parca citeam ca ar avea si asta un ocean subteran.

din pacate, dupa Marte, Uranus este cea mai buna optiune (chiar daca mie, personal, Jupiter mi se pare mai interesanta, cu furtunile ei magnetice and stuff). acuma ramane de decis daca schimbam numele planetei - ar fi pacat - sau stergem limba englezeasca de pe fatza pamantului. hey mr astronaut, what r u doing? i am going to mine gas in uranus :roll:

Dap, si ala. Dar tot e departe ca naiba si are conditiile de pe suprafata mult mai dure ca Marte.

Pentru că Waaagh n-a fost pe fază anul ăsta, fac eu onorurile:
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2016 with one half to

David J. Thouless
University of Washington, Seattle, WA, USA

and the other half to

F. Duncan M. Haldane
Princeton University, NJ, USA

and

J. Michael Kosterlitz
Brown University, Providence, RI, USA

”for theoretical discoveries of topological phase transitions and topological phases of matter”
They revealed the secrets of exotic matter

This year’s Laureates opened the door on an unknown world where matter can assume strange states. They have used advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids or thin magnetic films. Thanks to their pioneering work, the hunt is now on for new and exotic phases of matter. Many people are hopeful of future applications in both materials science and electronics.

The three Laureates’ use of topological concepts in physics was decisive for their discoveries. Topology is a branch of mathematics that describes properties that only change step-wise. Using topology as a tool, they were able to astound the experts. In the early 1970s, Michael Kosterlitz and David Thouless overturned the then current theory that superconductivity or suprafluidity could not occur in thin layers. They demonstrated that superconductivity could occur at low temperatures and also explained the mechanism, phase transition, that makes superconductivity disappear at higher temperatures.

In the 1980s, Thouless was able to explain a previous experiment with very thin electrically conducting layers in which conductance was precisely measured as integer steps. He showed that these integers were topological in their nature. At around the same time, Duncan Haldane discovered how topological concepts can be used to understand the properties of chains of small magnets found in some materials.

We now know of many topological phases, not only in thin layers and threads, but also in ordinary three-dimensional materials. Over the last decade, this area has boosted frontline research in condensed matter physics, not least because of the hope that topological materials could be used in new generations of electronics and superconductors, or in future quantum computers. Current research is revealing the secrets of matter in the exotic worlds discovered by this year’s Nobel Laureates.

Tocmai ti-am pasat formal capotul si caciula de secretar, poti sa te ocupi si de restul (baga si premiul in fiziologie de luni).

"The universe is nothing but a furtive arrangement of elementary particles. A figure in transition toward chaos. That is what will finally prevail. The human race will disappear.Other races in turn will appear and disappear.The skies will be glacial and empty, traversed by the feeble light of half-dead stars.These too will disappear.Everything will disappear."

Well...disapearing is an event in time and if you have no events and no time...
Chestrony, entropy will dispose of you long before dealing with the entire universe so you can just look forward to your death. We all do! Kidding...
