In this video, we explore the grand paradox of black holes and their implications for information conservation in the ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if you analyze the ashes of the fire, the smoke and the flames to re-create ...

Might the mere fact of creating a time machine ensure its own elimination from history? That’s the disquieting suggestion of a new theoretical framework by Andrew Jackson, a research associate at the ...

Can Information Escape a Black Hole? Black holes are inescapable traps for most of what falls into them — but there can be exceptions. The theoretical physicist Leonard Susskind speaks with co-host ...

Breaking the time asymmetry remains a fundamental yet tantalizing scientific challenge. At the macroscopic level the quest has so far turned out to be fruitless, but on the other hand in the subatomic ...

A flying mirror made by blasting a gas of electrons and ions with a powerful laser could help solve a long-standing mystery known as the black hole information paradox. This paradox arose in 1974 when ...

The rules of time-travel have been debated by scientists and sci-fi fans alike for years, but now a student physicist has been able to "square the numbers" to show how paradox-free time travel is ...

The fastest human in the world, according to the Ancient Greek legend, was the heroine Atalanta. Although she was a famous huntress who even joined Jason and the Argonauts in the search for the golden ...
