A small team of astrophysicists affiliated with several institutions in China has found evidence that suggests if wormholes are real, they might magnify light by 100,000 times. In their paper published in the journal Physical ...
A mysterious and very distant object, in a universe as it was 'just' two billion years after the Big Bang, hides from even the most advanced instruments. Its features have finally been described by a team from SISSA in a ...
