everything in and nothing could escape. But by combining quantum mechanics (量子力学)and the theory of relativity, Hawking showed something and changed everything about the way we think about gravity. Krauss says Hawking pointed out a(n)(4) J problem in the way physicists...
Absolutely. The acceleration of the universe is the smoking gun of something. Itmay well be dark energy, but there are other possibilities. It could be that gravity on larger scales doesn’t operate the way we think it does. The cleanest thing we can say is that the universe’s expansion...
Newton discovered the laws of motion and gravity, which laid the foundation for modern physics. And Curie discovered radium, which led to the development of new medical treatments for cancer. Today, scientists continue to make important discoveries that are helping us to address some of the world...
