WEBVTT 00:00:00.045 --> 00:00:03.540 Curiosity is one of humankind’s most beautiful traits. 00:00:04.050 --> 00:00:06.835 We want to know as much as possible about the world around us, 00:00:06.835 --> 00:00:09.750 but to satisfy our need to know about the world 00:00:09.750 --> 00:00:12.969 around us, our eyes just aren’t good enough anymore. 00:00:13.249 --> 00:00:16.650 With the power of engineering, we have been able to take a look at worlds 00:00:16.650 --> 00:00:20.606 hidden inside and outside the narrow range of our human senses. 00:00:21.126 --> 00:00:25.082 We can take a look at the smallest lifeforms, our own cells, and even 00:00:25.082 --> 00:00:27.648 molecules using electron microscopes. 00:00:28.198 --> 00:00:31.866 Complex machines that make invisible things visible, 00:00:31.866 --> 00:00:37.591 so we can discover worlds inside of worlds inside of worlds inside of worlds. 00:00:38.071 --> 00:00:40.995 Discoveries of the nanolevel have changed how we perceive 00:00:40.995 --> 00:00:44.989 the universe around us forever, and led to countless discoveries. 00:00:45.325 --> 00:00:49.294 On the other hand, just a few centuries ago engineers developed powerful 00:00:49.294 --> 00:00:52.662 tools of science that gave us the ability to look deep into space 00:00:52.662 --> 00:00:55.170 and spot countless wonders of the universe. 00:00:55.580 --> 00:00:58.121 Later came spacecraft and satellites. 00:00:58.511 --> 00:01:01.719 The Hubble telescope was one of these wonders of technology. 00:01:02.009 --> 00:01:06.117 Without it, we would never have known that our galaxy is one of billions in 00:01:06.117 --> 00:01:10.627 an enormous universe, and even better telescopes are being built right now. 00:01:10.827 --> 00:01:15.537 They’ll be able to show us worlds far, far away in much greater detail. 00:01:15.927 --> 00:01:18.930 So, there is still much left to discover. 00:01:19.330 --> 00:01:23.343 The universe is vast, and we have so much more to learn. 00:01:23.613 --> 00:01:28.197 And with the power of engineering and our curiosity, who knows what 00:01:28.163 --> 00:01:30.633 we’ll be able to discover in the future.
