Online Event: What Happened at the Big Bang(爆炸)?
Over the past few decades, we’ve made unbelievable discoveries about how our universe developed over the past 13. 8 billion years. But we still know very little about what happened in the first seconds after the big bang.
In the latest New Scientist online event, the speaker Dan Hooper will examine how physicists are using experiments to re-create the conditions of the big bang, and to deal with mysteries like how our universe came to contain so much matter and so little antimatter.
