Genesis, sta mislis, da li ce nas udariti neki asteroid u narednih, recimo, 50 godina?

Ako nekog zanima tema SMAK SVETA neka ustedi novac za casopis Astronomija broj 20. Ova tema ce biti detaljno obradjena.

Ne kako znas, nego zasto to nisi sprecio?!  :?  :)

Kad smo vec kod sudara sto ja nisam ovakve srece..? :(

Ne razumem  :o . Razumela sam da je neko doziveo sudar, ali sta se onda desava? Elem, po cenu da ispadnem smesna, koji se jezik koristi na datom sajtu? Poljski?

Sich

Poljski jeste, a radi se o tome kako je nekom meteorit bukvalno uleteo u kola :)

Cini mi se da se verovatnoca ovog desavanje ne moze meriti sa verovatnocom da covek, kome se to desilo, dobije na medjunarodnom loto-u (kada bi postojao), jer je mnogo manja! Znaci, uau.

:D Mislim da je veca verovatnoca da se u tom periodu ovo desi nego da Srbija udje u Evropsku Uniju npr., tako da narode - uzivajte u zivotu, jer nikad se ne zna sta sve moze da nas "strefi".

P.S. Kao sto procitah negde "...nemojte zivot shvatati previse ozbiljno, ionako necete iz njega izvuci zivu glavu!"  :P

Skywalker: ti si nesto naostren na nasu drzavu??? Ako, mozda jedina stvar koju imaju mladi od toga sto ih niko ne shvata ozbiljno, jeste sloboda govora :-)

Pa, ako imamo dovoljno srece... Moze i nama to da se dogodi?! Jel' prodao taj komad, taj lik sto mu je upao meteorit u kola???

GENESIS

Moj savet za mladje forumase.

Zavrsite fakultete i naucite strane jezike. Kopajte i rukama i nogama da odete iz "nase" "zemlje" da makar malo pozivite kao ljudi.

Ko ostane ovde ranije ili kasnije ce se gorko pokajati. :(

maxydelanoche

He he... Vazi!!!  :D

@ Genesis
E, ma nemoj  :? ! E, da znas da necu da mrdnem odavde; iz ove zemlje  :) . Ima da zapnem koliko znam i umem da stvorim sebi ovde "neke" uslove. A, ako nekome bude i dobro pri tom... jos bolje. I neka idu oni koji zele. Ako misle da je to prava solucija i da ce tako biti srecniji u zivotu.
Licno, volim da napravim razliku izmedju "biti turista" i "ziveti u inostranstvu". Plasim se da mnogi to ne rade. Ipak, sada neki klinci imaju priliku da odu u inostranstvo i da vide kako se tamo zivi. Takodje, i svi mi mozemo dobiti uvid kako se tamo zivi (sto preko onih koji su tamo, sto preko filmova, sto preko neta). Moj utisak je da nema potrebe da vristimo toliko za odlaskom. Znam jednu osobu koja je dala otkaz na poslu (u Beogradu!) na kojem je zaradjivala 1000 eura. Zasto?! Pa, zato sto je morala da radi vise od 8 sati. Hm. A ja cula da u inostranstvu radis 12h, ali imas kola, kucu bla, bla.
Takodje, danas svako moze da ode u inostranstvu, samo treba biti uporan. Pa, zasto onda ne odu i ostali? Razlozi su mnogi, naravno.
A molim vas, ne uzimajte "napredne" studente u obzir jer bi ti isti otisli pa ma kakva bila Srbija (radi se o klasicnoj razmeni intelegencije zemalja, sto se odigrava vec godinama i to medju svim zemljama).

Hawking: Space key to human survival

Wednesday, June 14, 2006; Posted: 11:07 p.m. EDT (03:07 GMT)

Astrophysicist Stephen Hawking attends a tree-planting ceremony in Hong Kong.

HONG KONG, China (AP) -- The survival of the human race depends on its ability to find new homes elsewhere in the universe because there's an increasing risk that a disaster will destroy Earth, world-renowned physicist Stephen Hawking said.

Humans could have a permanent base on the moon in 20 years and a colony on Mars in the next 40 years, the British scientist told a news conference.

"We won't find anywhere as nice as Earth unless we go to another star system," added Hawking, who came to Hong Kong to a rock star's welcome Monday. Tickets for his lecture Thursday were sold out.

Hawking said that if humans can avoid killing themselves in the next 100 years, they should have space settlements that can continue without support from Earth.

"It is important for the human race to spread out into space for the survival of the species," Hawking said. "Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers we have not yet thought of."

The 64-year-old scientist -- author of the global best-seller "A Brief History of Time" -- uses a wheelchair and communicates with the help of a computer because he suffers from a neurological disorder called amyotrophic lateral sclerosis, or ALS.

One of the best-known theoretical physicists of his generation, Hawking has done groundbreaking research on black holes and the origins of the universe, proposing that space and time have no beginning and no end.

However, Alan Guth, a physics professor at the Massachusetts Institute of Technology, said Hawking's latest observations were something of a departure from his usual research and more applicable to survival over the long-term.

"It is a new area for him to look at," Guth said. "If he's talking about the next 100 years and beyond, it does make sense to think about space as the ultimate lifeboat."

But, he added, "I don't see the likely possibility within the next 50 years of science technology making it easier to survive on Mars and on the moon than it would be to survive on earth."

"I would still think that an underground base, for example in Antarctica, would be easier to build than building on the moon," Guth said.

Joshua Winn, an astrophysicist at MIT, agreed. "The prospect of colonizing other planets is very far off, you must realize," he said.

Hawking's "work has been highly theoretical physics, not in astrophysics or global politics or anything like that," Winn added. "He is certainly stepping outside his research domain."

Hawking's comments Tuesday were reminiscent of the work of American astrophysicist Carl Sagan, who was a believer in the existence of extraterrestrial intelligence.

Sagan, a Cornell University professor and NASA-decorated scientist who died in 1996, noted that organic molecules, the kind that life on Earth is dependent on, appear to be almost everywhere in the solar system.

Sagan played a leading role in the U.S. space program, helping design robotic missions and contributing to the Mariner, Viking, Voyager and Galileo expeditions.

But his work also focused on the search for habitable worlds and intelligent life beyond the solar system, as well as theories about life's origins, ideas popularized in his best-selling 1985 novel, "Contact," which was made into a film starring Jodie Foster.

At Tuesday's news conference, Hawking said he too was venturing into the world of fiction. He plans to team up with his daughter, 35-year-old journalist and novelist Lucy Hawking, to write a children's book about the universe aimed at the same age group as the Harry Potter books.

"It is a story for children, which explains the wonders of the universe," said Lucy Hawking. They did not provide further details.
