Nikada mi neće dosaditi ovi prekrasni, daleki svjetovi i sve ove ljepote naših zemaljskih noći..Da mi toga nema, kamo bih usmjerila pogled, i gdje bih pronašla emocije ispunjene tragom uzdaha, i misli kojima bih noću, riječima s nebom ljubovala..

'SVEMIR JE MORAO NESTATI PAR TRENUTAKA NAKON NASTANKA!' Božja čestica otkrila rupu u teoriji
LONDON - Kada su prošle godine dva tima koja rade na Velikom hadronskom sudaraču (LHC) potvrdila postojanje Higgsovog bozona, takozvane ‘božje čestice,’ većina znanstvenog svijeta je slavila otkriće novog ‘svetog grala’ znanosti. Standardni model fizike je time apsolutno potvrđen, zaključili su.
No, nisu svi bili jednako sretni. Najpoznatiji teoretski fizičar današnjice, Stephen Hawking, bio je tužan zbog otkrića Higgsovog bozona. Razlog tomu nije bila oklada s Peterom Higgsom, koju je izgubio, već činjenica da se nadao da će LHC pronaći nešto drugačije, zanimljivije, što će zahtjevati potpuno novi pogled na fiziku i okrenuti dotadašnje teorije naglavačke.
Novo znanstveno istraživanje, objavljeno prije dva dana i predstavljeno na skupu Kraljevskog društva astronoma u Londonu, otkrilo je nevjerojatnu rupu u sadašnjim modelima fizike, koja je tu upravo zbog postojanja Higgsovog polja.
Robert Hogan i Malcom Fairbairn sa King’s Collegea u Londonu istražili su sve matematičke implikacije postojanja Higgsovog polja, i otkrili šokantnu činjenicu - univerzum je trebao potpuno kolabirati samo nekoliko trenutaka nakon nastanka.
Higgsov bozon je čestica-glasnik, koja drugim česticama daje masu kroz njihovu interakciju s Higgsovim poljem. Bez Higgsovog polja niti jedna čestica ne bi imala masu, i sve bi se čestice kretale brzinom svjetlosti.
Prema općeprihvaćenoj teoriji Velikog praska, svemir je ubrzo nakon nastanka (nekih 10^(-34) sekunde) prošao kroz fazu ‘inflacije’, u kojoj se izrazito naglo proširio. No, Hogan i Fairbairn pokazali su kako Higgsovo polje ne bi preživjelo takvu inflaciju. Došlo bi do ozbiljnih nestabilnosti i svemir bi kolabirao.
Ovaj par znanstvenika nudi i potencijalna rješenja za taj problem - jedna je mogućnost da je postojala inherentna povezanost između inflacije i Higgsovog polja, a druga je postojanje znatno veće temperature u vrijeme inflacije nego što je potvrđeno dosadašnjim mjerenjima.
Oba objašnjenja, na veliku sreću za Stephena Hawkinga, zahtjevaju ili postojanje dosad nepoznatih čestica, ili potpuno nove grane fizike, što znači da je pred astronomima novo i uzbudljivo razdoblje.

Time Travel: Theories, Paradoxes & Possibilities
Time travel — moving between different points in time — has been a popular topic for science fiction for decades. Franchises ranging from "Doctor Who" to "Star Trek" to "Back to the Future" have seen humans get in a vehicle of some sort and arrive in the past or future, ready to take on new adventures.
The reality, however, is more muddled. Not all scientists believe that time travel is possible. Some even say that an attempt would be fatal to any human who chooses to undertake it.
Understanding time
What is time? While most people think of time as a constant, physicist Albert Einstein showed that time is an illusion; it is relative — it can vary for different observers depending on your speed through space. To Einstein, time is the "fourth dimension." Space is described as a three-dimensional arena, which provides a traveler with coordinates — such as length, width and height —showing location. Time provides another coordinate — direction — although conventionally, it only moves forward. (Conversely, a new theory asserts that time is "real.")...

Ali znaš da su boje kompjuterski dodane? (pojačane)
Čiste snimke izgledaju navodno čisto drugačije...
Ovo kompjutersko dotjerivanje ti ga dođe kao neka kontrastna pretraga tijela, čisto da se naglasi nešto
But whatever, breathtaking .... da ne kvarim romantiku |
“Yesterday is but a dream,
Tomorrow is only a vision.
But today well lived makes every yesterday a dream of happiness, and every tomorrow a vision of hope.” |
