单身狗也是狗2019-07-03One of the great revelations of the space age has been the perspective it has given humanity on ourselves. When we see the Earth from space, we see ourselves as a whole. We see the unity, and not the divisions. It is such a simple image with a compelling message; one planet, one human race.

大名曹钢蛋2019-05-15当宇宙很大时，存在巨量掷骰子行为，结果平均到人们可以预测的程度。但是当宇宙非常小，在宇宙大爆炸附近，只有少量掷骰子行为，而不确定原理就非常重要。

大名曹钢蛋2019-05-15爱因斯坦强烈反对宇宙由偶然性制约的思想。他的感受可用他的一句名言来概括：“上帝不掷骰子。”但所有证据都表明，上帝是位地地道道的赌徒。

大名曹钢蛋2019-05-15所以记住仰望星空，而非注目脚下。尝试理解你所看到的，并追寻宇宙存在的原因。保持好奇心。

大名曹钢蛋2019-05-15但我们需要警惕，知道我们进一步发展之前，不要回答外星生命。在我们现阶段，遭遇更先进的文明，可能有点像美洲原住民遭遇哥伦布一样——我想他们认为他们的生活因之变得更糟。

海泊利安2019-05-08我在这个星球上过着一种非凡的生活，我利用奇思异想和物理定律穿越宇宙。我到过银河系最远处，旅行进入过黑洞，还返回过时间的起点。在这个地球上，我经历了高潮和低谷、动荡与安宁、成功和痛苦。我遭遇贫穷，享用富裕，曾经矫健，又身患残疾。我既受到赞扬，也受到批评，但从未被忽视过。通过我的研究，我非常荣幸地能够为人类对宇宙的理解做出贡献。但如果宇宙中不存在我所爱且爱我的人，那的确会是一个空虚的宇宙。没有他们，它的一切奇迹都对我毫无意义。

TheOtherSide2019-11-24Creating realistic digital surrogates of ourselves is an ambitious dream, but the latest technology suggests that it may not be as far-fetched an idea as it sounds.When I was younger, the rise of technology pointed to a future where we would all enjoy more leisure time. But in fact the more we can do, the busier we become. Our cities are already full of machines that extend our capabilities, but what if we could be in two places at once? We’re used to automated voices on phone systems and public announcements. Now inventor Daniel Kraft is investigating how we can replicate ourselves visually. The question is, how convincing can an avatar be?

TheOtherSide2019-11-24In short, the advent of super-intelligent AI would be either the best or the worst thing ever to happen to humanity. The real risk with AI isn’t malice but competence. A superintelligent AI will be extremely good at accomplishing its goals, and if those goalsaren’t aligned with ours we’re in trouble. You’re probably not an evil ant-hater who steps on ants out of malice, but if you’re in charge of a hydroelectric green-energyproject and there’s an anthill in the region to be flooded, too bad for the ants. Let’s not place humanity in the position of those ants. We should plan ahead. If a superior alien civilisation sent us a text message saying, “We’ll arrive in a few decades,” would we just reply, “OK, call us when you get here, we’ll leave the lights on”? Probably not, but this is more o...

TheOtherSide2019-11-24I was quoted at the time as saying that I feared the human race is not going to have a future if we don’t go into space. I believed it then, and I believe it still. And I hope I demonstrated then that anyone can take part in space travel. I believe it is up to scientists like me, together with innovative commercial entrepreneurs, to do all we can to promote the excitement and wonder of space travel.

TheOtherSide2019-11-24We can be an ignorant, unthinking lot. When we have reached similar crises in our history, there has usually been somewhere else to colonise. Columbus did it in 1492 when he discovered the New World. But now there is no new world. No Utopia around the corner. We are running out of space and the only places to go to are other worlds.The universe is a violent place. Stars engulf planets, supernovae fire lethal rays across space, black holes bump into each other and asteroids hurtle around at hundreds of miles a second. Granted, these henomena do not make space sound very inviting, but these are the very reasons why we should venture into space instead of staying put. An asteroid collision would be something against which we have no defence. The last big such collision with us was about six...

TheOtherSide2019-11-24I have a very personal interest in time. Firstly, my bestselling book, and the main reason that I am known beyond the confines of the scientific community, was called A Brief History of Time. So some might imagine that I am an expert on time, although of course these days an expert is not necessarily a good thing to be. Secondly, as someone who at the age of twenty-one was told by their doctors that they had only five years tolive, and who turned seventy-six in 2018, I am an expert on time in another sense, a much more personal one. I am uncomfortably, acutely aware of the passage of time, and have lived much of my life with a sense that the time that I have been granted is, as they say, borrowed.

TheOtherSide2019-11-24The history books and our memories could just be illusions. It is the past that tells us who we are. Without it, we lose our identity

TheOtherSide2019-11-24Einstein objected strongly to the idea that the universe is governed by chance. His feelings were summed up in his dictum “God does not play dice.” But all the evidence is that God is quite a gambler. The universe is like a giant casino with dice being rolled, or wheels being spun, on every occasion. A casino owner risks losing money each time dice are thrown or the roulette wheel is spun. But over a large number of bets the odds average out, and the casino owner makes sure they average out in his or her favour. That’s why casino owners are so rich. The only chance you have of winning against them is to stake all your money on a few rolls of the dice or spins of the wheel.

TheOtherSide2019-11-23People want answers to the big questions, like why we are here. They don’t expect the answers to be easy, so they are prepared to struggle a bit. When people ask me if aGod created the universe, I tell them that the uestion itself makes no sense. Time didn’t exist before the Big Bang so there is no time for God to make the universe in. It’s like asking for directions to the edge of the Earth—the Earth is a sphere that doesn’t have an edge, so looking for it is a futile exercise.Do I have faith? We are each free to believe what we want, and it’s my view that the simplest explanation is that there is no God. No one created the universe and no one directs our fate. This leads me to a profound realisation: there is probably no heaven and afterlife either. I think belief in an afterlife is jus...

TheOtherSide2019-11-23I hope that science and technology will provide the answers to these questions,but it will take people, human beings with knowledge and understanding, to implement these solutions. Let us fight for every woman and every man to have the opportunity to live healthy, secure lives, full of opportunity and love. We are all time travellers, journeying together into the future. But let us work together to make that future a place we want to visit.Be brave, be curious, be determined, overcome the odds. It can be done.

TheOtherSide2019-11-23To see how, imagine a clock is being sucked into it. As the clock gets closer and closer to the black hole, it begins to get slower and slower. Time itself begins to slow down. Now imagine the clock as it enters the black hole—well, assuming of course that it could withstand the extreme gravitational forces—it would actually stop. It stops not because it is broken, but because inside the black hole time itself doesn’t exist. And that’s exactly what happened at the start of the universe.

熹微2020-07-06有朝一日，我希望我们能够知道所有这些问题的答案。但还有其他挑战，必须回答地球上的其他重大问题，这些也需要新一代感兴趣和参与，而且他们还得对科学有所了解。我们将如何养活不断增长的人口？如何提供干净的水、产生可再生能源、防止并治愈疾病、减缓全球气候变化？我希望科学技术能够回答这些问题，但需要人，有知识和理解力的人，去实施这些解决方案。让我们为每个女人和男人奋斗，为了让他们都能过上健康、安全，并充满了机会和爱的生活。我们都是时间旅行者，让我们一起踏入未来。让我们共同努力，使这个未来成为我们想去访问的地方。勇敢、好奇、坚定、战胜困难。我们一定能够做到。
