181 " As I was growing up in England after the Second World War, it was a time of austerity. We were told that you never get something for nothing. But now, after a lifetime of work, I think that actually you can get a whole universe for free. "
― Stephen Hawking , Brief Answers to the Big Questions
182 " De una forma u otra, considero casi inevitable que haya alguna confrontación nuclear o que la catástrofe ambiental paralice la Tierra en algún momento en los próximos mil años, que en comparación con el tiempo geológico es un simple abrir y cerrar de ojos. Para entonces espero y creo que nuestra ingeniosa especie habrá encontrado alguna manera de escuchar los lamentos de la Tierra y, por lo tanto, de sobrevivir al desastre. "
183 " existential "
184 " Todos somos viajeros en el tiempo, viajamos juntos hacia el futuro. Trabajemos unidos para construir ese futuro, un lugar que nos guste visitar. Seamos valientes, curiosos, decididos, superemos las dificultades. Se puede conseguir. "
185 " surrogates "
186 " la mayoría de la gente cree que la ciencia real es demasiado difícil "
187 " unirse. Necesitamos reavivar la emoción de los primeros días del viaje espacial en los años sesenta. La tecnología está casi a nuestro alcance. Es hora de explorar otros sistemas solares; puede ser lo único que nos salve de nosotros mismos. Estoy convencido de que los humanos necesitamos dejar la Tierra para evitar correr el riesgo de ser aniquilados. "
188 " la mayoría de la gente cree que la ciencia real es demasiado difícil y complicada para que la puedan entender. "
189 " People asked a computer, “Is there a God?” And the computer said, “There is now,” and fused the plug. "
190 " Espero que en el futuro, incluso cuando yo ya no esté, las personas con poder puedan mostrar creatividad, coraje y liderazgo. Dejémosles ponerse al nivel del desafío de los objetivos de desarrollo sostenible, y actuar no por su propio interés sino por el interés común. "
191 " information paradox "
192 " En el instante del Big Bang, algo maravilloso sucedió con el tiempo. El tiempo mismo comenzó. "
193 " What happened before the beginning ? What was God doing before he made the world? Was he preparing Hell for people who asked such questions? "
194 " Hamlet said, “I could be bounded in a nutshell, and count myself a king of infinite space.” I think what he meant was that although we humans are very limited physically, particularly in my own case, our minds are free to explore the whole universe, and to boldly go where even Star Trek fears to tread. "
195 " ... remember to look up at the stars and not at your feet. Try to make sense of what you see and wonder about what makes the the universe exist. Be curious.And however difficult life may seem, there is always something you can do and succeed at.It matters that you don't just give up. Unleash your imagination. Shape the future. "
196 " At the beginning of the twentieth century we understood the workings of nature on the scales of classical physics that are good down to about a hundredth of a millimetre. The work on atomic physics in the first thirty years of the century took our understanding down to lengths of a millionth of a millimetre. Since then, research on nuclear and high-energy physics has taken us to length scales that are smaller by a further factor of a billion. It might seem that we could go on forever discovering structures on smaller and smaller length scales. However, there is a limit to this series as with a series of nested Russian dolls. Eventually one gets down to a smallest doll, which can’t be taken apart any more. In physics the smallest doll is called the Planck length and is a millimetre divided by a 100,000 billion billion billion. We are not about to build particle accelerators that can probe to distances that small. "
197 " It means the universe itself, in all its mind-boggling vastness and complexity, could simply have popped into existence without violating the known laws of nature. "
198 " Opening up the thrill and wonder of scientific discovery, creating innovative and accessible ways to reach out the widest audience possible, greatly increases the chances of finding and inspiring the new Einstein. Wherever she might be. "
199 " but also that it is possible that nothing caused the Big Bang. Nothing. "
200 " I have been praised and criticised, but never ignored. "
