Uskoro ćemo moći vidjeti misteriozni horizont događanja crne rupe? (Fun)

Crne rupe su jedne od najmisterioznijih objekata u svemiru. Radi se o malom prostoru u kojem se nalazi velika zbijena masa, a nastala je urušavanjem zvijezde. Iz crne se rupe ništa, pa čak ni svjetlost, ne može odvojiti zbog jake gravitacije, a nakon što se prijeđe horizont događaja. Horizont događaja je površina zamišljene kugle oko sfernosimetrične raspodjele mase iz koje ne može izaći nikakav oblik materije ili energije.

Uskoro bi tim znanstvenika koji rade na Event Horizon Teleskopu mogao napraviti pravu senzaciju u astronomiji. Znanstvenici se nadaju da će ispitati fundamentalne teorije o crnim rupama, te napraviti prvu sliku horizonta događanja crne rupe, što je, kao što smo već napisali, prostor iz kojeg ništa ne može pobjeći. Istraživači će povrezati više radioteleskopa kako bi dobili jedan divovski teleskop kojim će zaviriti u samo srce naše galaksije gdje se nalazi crna rupa 4 milijuna puta masivnija nego naše Sunce, naziva Sagittarius A. Astronomi znaju da se ondje nalazi disk plina i prašine koji orbitira oko crne rupe. Sceince Alert


Horizont događaja razdvaja prostor na dva dijela između kojih je nemoguća komunikacija: prostor unutar i izvan horizonta događaja.

Gibanje u prostoru izvan horizonta događaja: Ako promatramo svemirski brod koje pada prema crnoj rupi, na njemu opažamo vremensku dilataciju uzrokovanu gravitacijskim zakrivljenjem prostora oko crne rupe. Drugim riječima, nama kao udaljenom promatraču se čini kao da vrijeme na svemirskom brodu sve sporije i sporije teče. Kada svemirski brod dođe do horizonta događaja, nama se čini kao da je na svemirskom brodu vrijeme stalo, tj. bilo koji konačni interval vremena na svemirskom brodu beskonačno traje za udaljenog promatrača.

Gibanje u prostoru unutar horizonta događaja: Bilo koje tijelo koje se nađe unutar horizonta događaja nužno prije ili kasnije završava u središnjoj singularnosti. To znači da je nemoguće izaći izvan horizonta događaja. Wikipedia

About the game:


USA as a world power? In E-Sim it is possible!

In E-Sim we have a huge, living world, which is a mirror copy of the Earth. Well, maybe not completely mirrored, because the balance of power in this virtual world looks a bit different than in real life. In E-Sim, USA does not have to be a world superpower, It can be efficiently managed as a much smaller country that has entrepreneurial citizens that support it's foundation. Everything depends on the players themselves and how they decide to shape the political map of the game.

Work for the good of your country and see it rise to an empire.

Activities in this game are divided into several modules. First is the economy as a citizen in a country of your choice you must work to earn money, which you will get to spend for example, on food or purchase of weapons which are critical for your progress as a fighter. You will work in either private companies which are owned by players or government companies which are owned by the state. After progressing in the game you will finally get the opportunity to set up your own business and hire other players. If it prospers, we can even change it into a joint-stock company and enter the stock market and get even more money in this way.


In E-Sim, international wars are nothing out of the ordinary.

"E-Sim is one of the most unique browser games out there"

Become an influential politician.

The second module is a politics. Just like in real life politics in E-Sim are an extremely powerful tool that can be used for your own purposes. From time to time there are elections in the game in which you will not only vote, but also have the ability to run for the head of the party you're in. You can also apply for congress, where once elected you will be given the right to vote on laws proposed by your fellow congress members or your president and propose laws yourself. Voting on laws is important for your country as it can shape the lives of those around you. You can also try to become the head of a given party, and even take part in presidential elections and decide on the shape of the foreign policy of a given state (for example, who to declare war on). Career in politics is obviously not easy and in order to succeed in it, you have to have a good plan and compete for the votes of voters.


You can go bankrupt or become a rich man while playing the stock market.

The international war.

The last and probably the most important module is military. In E-Sim, countries are constantly fighting each other for control over territories which in return grant them access to more valuable raw materials. For this purpose, they form alliances, they fight international wars, but they also have to deal with, for example, uprisings in conquered countries or civil wars, which may explode on their territory. You can also take part in these clashes, although you are also given the opportunity to lead a life as a pacifist who focuses on other activities in the game (for example, running a successful newspaper or selling products).


At the auction you can sell or buy your dream inventory.

E-Sim is a unique browser game. It's creators ensured realistic representation of the mechanisms present in the real world and gave all power to the players who shape the image of the virtual Earth according to their own. So come and join them and help your country achieve its full potential.
