[00:00.000] 作词 : Stephen William Hawking[00:01.000] 作曲 : 这是V启[00:02.744]The questions i would like to talk about are:[00:08.816]one[00:10.669]where did we come from?[00:25.186]how did the universe come from into being?[00:31.487]what is the future of the human race?[00:37.216]is there alien life out there?[00:44.916]are we alone in the universe?[01:15.526]i now turn to the second big question:[01:18.386]are we alone,or is there other life in the universe?[01:24.457]we believe that life arose spontaneously on the Earth,[01:28.405]so it must be possible for life to appear on other suitable planets,[01:33.096]of which there seem to be a large number in the galaxy.[01:39.396]but we don't know how life first appeared.[01:47.036]this brings me to the last of the big questions:[01:50.166]the future of the human race.[01:53.588]if we are the only intelligent beings in the galaxy,[01:57.286]we should make sure we survive and continue.[02:36.456]i think it quite likely that we are the only civilization[02:39.906]within several hundred light years;[02:44.145]otherwise we would have heard radio waves.[02:50.487]the alternative is that civilizations don’t last very long,[02:54.985]but destroy themselves.
