Physicist who explains the universe of Stephen Hawking
Hello guys, again at Smartviewers this time we will discuss someone who is a very famous physicist from the beginning until now his name is Stephen Hawking
He died on March 14, 2018, was one of the most famous theoretical physicists in history. His work on the origin and structure of the universe revolutionized physics into what we know today.
Beginning of Story
Hawking was born in England on January 8, 1942. He studied physics at University College even though his father asked him to study medicine. After graduating, he researched cosmology at Cambridge University.

Fisikiawan yang menjelaskan alam semesta Stephen Hawking
Halo guys kembali lagi di smartviewers kali ini kita bakal ngebahas seseorang fisikiawan yang sangat terkenal dari dulu sampai sekarang namanya adalah Stephen Hawking
Ia meninggal pada 14 Maret 2018 merupakan salah satu fisikawan teoritis paling ternama dalam sejarah. Karyanya mengenai asal-usul dan struktur alam semesta merevolusi fisika menjadi yang kita kenal sekarang.
Awal Kisah
Hawking lahir di Inggris pada 8 Januari 1942. Dia mempelajari ilmu fisika di University College walaupun ayahnya memintanya belajar pengobatan. Setelah lulus, dia meneliti kosmologi di Cambridge University.

English: 
In early 1963, Hawking, who at that time wanted his 21st birthday, was diagnosed with amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease. He was thought to only be able to survive for two years, but in fact could live to be 76 years old.
However, Hawking's ALS disease is not without impact. He slowly lost his ability to move and had to use a wheelchair. In 1985, Hawking had to undergo a tracheostomy operation which made him lose the ability to speak.
Fortunately, a tool made by Cambridge University helped him to communicate. Hawking can choose his words just by moving the muscles on the cheeks.
A genius
His illness did not break Hawking's desire to explore the universe. During his career, Hawking tried to uncover the mysteries of the universe. He also hypothesized that if the universe had a beginning, that is the Big Bang, then it would have an end too.

Indonesian: 
Pada awal tahun 1963, Hawking yang saat itu mau berulang tahun yang ke-21 dia didiagnosis  amyotrophic lateral sclerosis (ALS) atau penyakit Lou Gehrig. Dia sempat dikira hanya akan bisa bertahan hidup selama dua tahun, tetapi nyatanya bisa hidup hingga usia 76 tahun.
Namun, penyakit ALS yang diderita Hawking bukan tanpa dampak. Ia perlahan-lahan kehilangan kemampuannya untuk bergerak dan harus memakai kursi roda. Pada tahun 1985, Hawking harus menjalani operasi trakeostomi yang membuatnya kehilangan kemampuan untuk berbicara.
Untungnya, sebuah alat yang dibuat oleh Cambridge University membantunya untuk berkomunikasi. Hawking bisa memilih kata-katanya hanya dengan menggerakan otot pada pipi.
Seorang Genius
Penyakitnya tidak mematahkan keinginan Hawking untuk mengeksplorasi alam semesta. Selama kariernya, Hawking mencoba menguak misteri alam semesta. Dia pun berhipotesis bahwa jika alam semesta memiliki awal, yaitu Big Bang, maka ia akan memiliki akhir juga.

English: 
Hawking worked with cosmologist Roger Penrose and demonstrated Albert Einstein's Theory of General Relativity which showed that there was a time when space began at the birth of the universe and ended with a black hole.
Combining Einstein's theory and quantum theory, Hawking discovered that black holes do not stand still. Black holes actually hiss, emit radiation and particles, before finally exploding and disappearing.
When he realized this, Hawking himself could not believe it. However, all calculations returned to the same result.
The results were later published in 1974 in an article titled "Black Hole Blast?" in the journal Nature and gave rise to a new concept called Hawking radiation.
In 2014, Hawking revised his theory and stated that black holes do not exist, at least black holes that we have traditionally known. In this controversial new theory,

Indonesian: 
Hawking bekerja sama dengan pakar kosmologi yaitu Roger Penrose dan mendemonstrasikan Teori Relativitas Umum Albert Einstein yang menunjukkan bahwa ruang angkasa ada waktu dimulai pada kelahiran alam semesta dan berakhir dengan lubang hitam.
Memadukan teori Einstein dan teori kuantum, Hawking menemukan bahwa lubang hitam tidak diam saja. Lubang hitam justru berdesis, mengeluarkan radiasi dan partikel, sebelum akhirnya meledak dan menghilang.
Ketika menyadari hal ini, Hawking sendiri sempat tidak memercayainya. Namun, semua kalkulasinya kembali ke hasil yang sama.
Hasil tersebut kemudian dipublikasikan pada 1974 dalam artikel berjudul “Ledakan Lubang Hitam?” di jurnal Nature dan memunculkan konsep baru bernama radiasi Hawking.
Pada 2014, Hawking merevisi teorinya dan menyatakan bahwa lubang hitam tidak ada, setidaknya lubang hitam yang kita kenal secara tradisional. Dalam teori baru yang kontroversial ini,

English: 
Hawking does not recognize the event horizon or black hole boundaries. Instead, he said black holes have horizons that will change according to quantum changes. In addition, Hawking also claims that the universe has no limits.
Even though the number of planets is limited, one can surround it without limits and will never meet a wall.
Aside from being a scientist, Hawking is also a popular book writer. His first book, published in 1988 under the title A Brief History of Time, has sold more than 10 million copies.
Beyond pen and paper, Hawking has also appeared several times on television, including acting as himself in an episode of Star Trek entitled: The Next Generation and Big Bang Theory. He also had an educational miniseries titled Stephen Hawking's Universe.
He has also appeared in The Simpsons and GoCompare insurance comparison website ads. His voice in the ad was then used by Pink Floyd for their song entitled Keep Talking.
The last and perhaps best known by the people of Indonesia is a film called The Theory of Everything that makes Hawking reflect on his life again.

Indonesian: 
Hawking tidak mengakui adanya horizon peristiwa atau batas lubang hitam. Sebaliknya, dia berkata lubang hitam memiliki horizon yang akan berubah menurut perubahan kuantum. Selain itu, Hawking juga mengklaim bahwa alam semesta ini tidak memiliki batas.
Walaupun jumlah planetnya terbatas, seseorang bisa mengelilingnya tanpa batas dan tidak akan pernah bertemu dinding.
Selain sebagai seorang ilmuwan, Hawking juga penulis buku yang populer. Buku pertamanya yang dipublikasikan pada 1988 dengan judul A Brief History of Time telah terjual lebih dari 10 juta kopi.
Di luar pena dan kertas, Hawking juga tampil beberapa kali di televisi, termasuk berperan sebagai dirinya sendiri di satu episode Star trek yang berjudul : The Next Generation dan Big Bang Theory. Ia juga pernah memiliki acara miniseri edukasi berjudul Stephen Hawking’s Universe.
Dia juga pernah muncul dalam The Simpsons dan iklan situs pembanding asuransi GoCompare. Suaranya dalam iklan tersebut kemudian digunakan Pink Floyd untuk lagu mereka yang berjudul Keep Talking.
Terakhir dan mungkin paling dikenal oleh masyarakat Indonesia adalah film berjudul The Theory of Everything yang membuat Hawking merefleksikan kehidupannya kembali.

English: 
In his Facebook account, Hawking wrote in 2014, even though I was severely flawed, I had been very successful in my field.
I had traveled far and away to Antarctica and Easter Island, climbed into submarines and boarded flights without gravity. "One day, I hope to go to space," he added.

Indonesian: 
Dalam akun Facebook-nya, Hawking menulis pada 2014, walaupun aku cacat parah, aku telah sangat sukses di bidangku.
Aku telah berkelana jauh dan pernah ke Antartika dan Easter Island, turun ke dalam kapal selam dan naik ke penerbangan tanpa gravitasi. “Suatu hari, aku berharap bisa ke luar angkasa,” imbuhnya.
