Cosmologist Stephen Hawking changed our view of the universe with his remarkable theories and outreach. He also inspired generations around the world, making some of the most complicated physics of our time accessible to the masses.
He also suffered from amyotrophic lateral sclerosisor, or ALS, also known as Lou Gehrig's disease, which gradually paralyzed him over the decades. Despite this crippling disease, Hawking produced ground-breaking theories on black holes and other celestial phenomena.

他还患有肌萎缩性脊髓侧索硬化症(ALS)，也被称为卢伽雷氏症(Lou Gehrig’s disease)，在过去的几十年里，这种疾病让他逐渐瘫痪。尽管身患这种致残的疾病，霍金还是提出了关于黑洞和其他天体现象的突破性理论。
