Ilustração de um buraco negro supermaciço: observatório de ondas gravitacionais no espaço pode ajudar a identificar nova e ainda desconhecida propriedade comum destes misteriosos objetos além de sua massa, carga e rotação, que os cientistas apelidaram de “cabelo” NASA/JPL

Nova missão espacial pode ajudar cientistas a responder questões “cabeludas” sobre os buracos negros

O estudo teórico de buracos negros de rotação rápida está ajudando os físicos a entender melhor os misteriosos buracos negros do Universo
Lubang Hitam adalah objek yang sangat kompak sehingga tidak ada yang bisa lepas dari tarikan gravitasinya, bahkan tidak ringan. Mereka terbentuk ketika bintang mati dan mulai runtuh di bawah berat badan mereka sendiri. Jauh di dalam Lubang Hitam berada objek yang sangat panas dan padat, yang disebut, singularitas.

Fisikawan teoritis meraih Hadiah Nobel 2020 atas riset Lubang Hitam, ini manfaat temuannya yang menarik

Hadiah Nobel 2020 di bidang fisika diberikan kepada tiga ilmuwan dari Inggris, Amerika, dan Jerman atas dedikasinya yang luar biasa dalam memahami objek paling misterius di angkasa: Lubang Hitam.
A black hole is an object so compact that nothing can escape its gravitational pull, not even light. They are formed when stars die and start collapsing under their own weight. Deep inside the black hole resides an infinitely hot and dense object, a so-called, singularity. Science Photo Library - MARK GARLICK/Getty Images

2020 Nobel Prize in physics awarded for work on black holes – an astrophysicist explains the trailblazing discoveries

The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.

Rotating black holes may serve as gentle portals for hyperspace travel

Feel like visiting another star system or dimension? You can do this by traveling through a spacetime portal of a black hole. But you better choose carefully. All black holes are not created equal.

Time travel is possible – but only if you have an object with infinite mass

Who wouldn’t want to travel in time, glimpsing the dinosaurs or peeking at humans 2,000 years from now? Now physicists have designed a time machine that seems deceptively simple.
