Well hello and welcome to this English lesson about science
0
0
3961
00:03
fiction. You may have expected this lesson because a couple
1
3961
4160
00:08
weeks ago we did one on medieval times and fantasy. So
2
8121
3560
00:11
this is the natural follow up. Science fiction is also
3
11681
4920
00:16
fiction. Stories that aren't true but they take place in the
4
16601
3480
00:20
future. I am a big science fiction fan. I love reading
5
20081
4200
00:24
science fiction and I like watching Science fiction
6
24281
2920
00:27
movies. Um so in this English I'll help you learn some words
7
27201
4100
00:31
and phrases that hopefully help you understand a science
8
31301
4160
00:35
fiction book if you read it or when you watch a science
9
35461
2920
00:38
fiction movie and there are a lot of them there are a lot of
10
38381
3760
00:42
science fiction movies in the world. So once again welcome to
11
42141
3920
00:46
this English lesson about science fiction. So science
12
46061
3760
00:49
fiction relates to stories about the future. Someone has
13
49821
4920
00:54
imagined the future and they've written a story about it or
14
54741
3160
00:57
they've created a movie about it. Um so we have a short form
15
57901
3820
01:01
though for science fiction and it's the word sci-fi. So if you
16
61721
4120
01:05
are a fan of sci-fi it means you really like science
17
65841
3000
01:08
fiction. I'm not sure why we do this in English so often.
18
68841
3640
01:12
Science fiction isn't that hard to say but for some reason we
19
72481
3120
01:15
shorten it and we sometimes say sci-fi. We even have a channel
20
75601
4320
01:19
here called the sci-fi channel although they spell it a little
21
79921
3080
01:23
differently. This is the most correct spelling. But sci-fi
22
83001
3880
01:26
once again about the future. Stories about robots and
23
86881
4780
01:31
spaceships and people travelling from planet to
24
91661
3360
01:35
planet. People living in futuristic cities. That is what
25
95021
4400
01:39
science fiction is all about. Stories about the future. And
26
99421
3960
01:43
sci-fi is the short version of it. Mostly these stories take
27
103381
5600
01:48
place in outer space. Most people who imagine the future
28
108981
4320
01:53
imagine us travelling from our planet to other planets.
29
113301
5280
01:58
Sometimes outer space involves our solar system. And maybe we
30
118581
5200
02:03
on Mars as well as the planet Earth but sometimes outer space
31
123781
4120
02:07
involves travelling far beyond our solar system to other parts
32
127901
4280
02:12
but the vast majority of stories that people write that
33
132181
4760
02:16
would be called science fiction take place in outer space or at
34
136941
4360
02:21
the very least on a very futuristic earth planet earth
35
141301
6840
02:28
and of course planets and stars make up the majority of the
36
148141
4040
02:32
places where people go. They might be travelling to a
37
152181
3280
02:35
distant planet. They might be travelling to a distant star.
38
155461
3320
02:38
They might be travelling to visit people who live on a
39
158781
3280
02:42
different planet. Planets would be things like earth and stars
40
162061
4200
02:46
would be things like our very own sun. The sun is actually a
41
166261
3880
02:50
star. A galaxy though is a whole bunch of planets and
42
170141
6820
02:56
stars and other space things together and spinning. We
43
176961
5360
03:02
actually are in the Milky Way galaxy. The planet Earth is in
44
182321
3640
03:05
the Milky Way. But a galaxy is a collection of planets and
45
185961
3880
03:09
stars and other things. Kind of spinning and connected to each
46
189841
4880
03:14
other through probably their own gravity. I'm not sure I'm
47
194721
3720
03:18
not an expert. But definitely a galaxy is a large collection of
48
198441
3920
03:22
planet and star planets and stars. And the one we live in
49
202361
3760
03:26
is called the Milky Way. So if you look up in the sky
50
206121
3720
03:29
sometimes on a perfect night you can see it looks a little
51
209841
4680
03:34
bit milky. It looks a little bit white because of all the
52
214521
3480
03:38
stars that are in our galaxy. And if you refer to everything
53
218001
7600
03:45
that includes every single galaxy. Every single planet.
54
225601
3480
03:49
Every single star. Uh everything that exists. We call
55
229081
3680
03:52
it the universe. And we do put the word the in front. So our
56
232761
4560
03:57
galaxy is in the universe. We all live in the universe. The
57
237321
3080
04:00
universe is huge. The universe is endless. I don't know a lot
58
240401
5120
04:05
about the universe but it's definitely really really big.
59
245521
3960
04:09
And everything that exists is in the universe. Hey the people
60
249481
6200
04:15
that go into space or outer space are called astronauts.
61
255681
4920
04:20
There are astronauts from many countries on earth and we tend
62
260601
4120
04:24
to work quite well together. It's one of the things where a
63
264721
3920
04:28
lot of different countries work well together in terms of
64
268641
4600
04:33
having a space station travelling to space. Things are
65
273241
3240
04:36
a little rough around the edges right now in terms of countries
66
276481
4720
04:41
relating well to each other in terms of going to space. But if
67
281201
4040
04:45
you were to talk about someone who goes to space we would call
68
285241
3440
04:48
them an astronaut. So a lot of astronauts will go to space.
69
288681
4160
04:52
They'll do some experiments on the space station and then
70
292841
2760
04:55
they'll come back. In the far future people who travel aren't
71
295601
4800
05:00
always called astronauts. Um I think when space flight becomes
72
300401
5320
05:05
common people are just passengers. You're no longer an
73
305721
3280
05:09
astronaut. And we also have theories that there might be
74
309001
4840
05:13
extraterrestrials or aliens that live somewhere else in our
75
313841
4560
05:18
galaxy or in the universe. People are going to ask this
76
318401
3680
05:22
question. I know. They're going to say Bob do you think
77
322081
2360
05:24
aliens exist? And all all I'll say is I don't think so. I
78
324441
3800
05:28
think they would have visited by now. But extraterrestrials
79
328241
3680
05:31
would be
80
331921
2400
05:34
creatures or I can't say people. They would be beings
81
334841
4580
05:39
from another planet. They would be people who are not human who
82
339421
5360
05:44
evolved or developed outside of our planet and solar system. So
83
344781
5200
05:49
it's hard to describe what an extraterrestrial is. Not a
84
349981
3080
05:53
human not from Earth. There that's my best explanation. And
85
353061
5400
05:58
we also sometimes talk about it in a broader term. We'll just
86
358461
4000
06:02
say intelligent life. There's the search for intelligent
87
362461
3360
06:05
life. They're looking for in Intelligent creatures from
88
365821
4040
06:09
other parts of our galaxy. And once again do I think
89
369861
3440
06:13
intelligent life exists? Um outside of the planet Earth. I
90
373301
5240
06:18
I don't know. I don't think so. But I don't I could be proven
91
378541
3880
06:22
wrong at some point in the future. But currently I think
92
382421
2800
06:25
that it's just us. That's that's my that's my feeling. Um
93
385221
5480
06:30
so when you travel in space you will use a spaceship. So a
94
390701
4360
06:35
spaceship is a vehicle that has been designed to go in space.
95
395061
5420
06:40
Space has a near vacuum or vacuum. There's nothing in
96
400481
4960
06:45
space. There's no air around you. So you need a special ship
97
405441
4080
06:49
that can go in a vacuum. You need a ship that can travel
98
409521
3280
06:52
safely through space and we would call that a spaceship. We
99
412801
4000
06:56
might also call it a starship. Uh if you have watched Star
100
416801
5600
07:02
Trek at all they have starships like the Starship Enterprise.
101
422401
3440
07:05
So a starship is simply a spaceship that is able to
102
425841
3840
07:09
travel between stars. Okay so a general term Would be
103
429681
4840
07:14
spaceship. A specific term for a spaceship that can go really
104
434521
6280
07:20
far really fast and travel between stars would be a
105
440801
3840
07:24
starship. Uh very cool. If you've ever watched Star Trek
106
444641
4640
07:29
you will enjoy many episodes of people travelling from Stars to
107
449281
7660
07:36
Star. Um and I do want to mention I'm not a Star Wars fan
108
456941
5120
07:42
or a Star Trek fan primarily. I am a fan of both. Some Star
109
462061
4440
07:46
Wars fans don't like Star Trek and some Star Trek fans don't
110
466501
3440
07:49
like Star Wars. I like both. And I really do enjoy both of
111
469941
4160
07:54
them. And of course we on Earth here are still sending up
112
474101
4840
07:58
rockets. A rocket is a vehicle designed to travel from the
113
478941
3960
08:02
Earth into space. Um well some are designed to travel from
114
482901
4540
08:07
earth into space but a rocket is usually just a long tall
115
487441
3640
08:11
vehicle with a big rocket engine at the bottom and we
116
491081
4400
08:15
count down ten, nine, eight, 7, six, five, four, three, two,
117
495481
4080
08:19
one, zero, blast off. When we were kids, we would often do
118
499561
4240
08:23
that like we would count backwards and when we got to
119
503801
2720
08:26
zero, we would say blast off because the rocket when the
120
506521
3360
08:29
countdown hits zero, the engines ignite, the rocket
121
509881
3240
08:33
engines ignite and it will take off. So, rockets are one the
122
513121
4700
08:37
ways that we travel from earth to space or just to send up a
123
517821
5560
08:43
satellite. Uh we have another kind of vehicle called a UFO.
124
523381
4440
08:47
This is an unidentified flying object. I didn't put the full
125
527821
3880
08:51
term on the screen. But a UFO would be anything flying that
126
531701
6120
08:57
we can't identify. Usually it ends up being a satellite or a
127
537821
4800
09:02
weather balloon or something else. Uh some people believe
128
542621
3480
09:06
that aliens come in UF FOs to the earth and visit secretly at
129
546101
5040
09:11
night. I'm not so sure about that. And then we have what's
130
551141
5080
09:16
called a shuttle. There's a couple different kinds of
131
556221
2200
09:18
shuttles. This is a space shuttle. As soon as you use the
132
558421
4080
09:22
word shuttle it means it can travel back and forth. Um so a
133
562501
4920
09:27
shuttle is something that can take you from one place to
134
567421
2720
09:30
another. At the airport you can take a shuttle from the parking
135
570141
3440
09:33
lot to the airport. And then from the airport to the parking
136
573581
2720
09:36
lot you can take the space to the space station and then you
137
576301
3780
09:40
can fly back down and then take it again. In science fiction
138
580081
4000
09:44
sometimes a starship or spaceship will send a shuttle
139
584081
3440
09:47
from their ship to another ship. And it's just a shuttle's
140
587521
3200
09:50
just a smaller spaceship that you can fly back and forth
141
590721
3800
09:54
between one ship to another. Space Station. So this is a
142
594521
5360
09:59
very advanced looking space station. Uh the current space
143
599881
4240
10:04
stations do not look like this. But one of the theories is that
144
604121
4120
10:08
as we move into the future we will eventually have space
145
608241
3560
10:11
stations. A lot of Science fiction books and movies. Um
146
611801
4740
10:16
they either visit a space station or they stop to refuel
147
616541
4120
10:20
at a space station or to take on supplies. Maybe they need
148
620661
3960
10:24
food and water. So a space station is just a large base or
149
624621
5560
10:30
station in space somewhere that humans have built where they
150
630181
4520
10:34
can visit with spaceships to resupply to I don't know hire
151
634701
6080
10:40
new people if they need more astronauts not sure. And then
152
640781
4500
10:45
if we build something on the moon or another planet the very
153
645281
4040
10:49
first structures we build will be called a base. So when we
154
649321
4480
10:53
travel to the moon eventually we'll build a base on the moon.
155
653801
3240
10:57
When we travel to Mars we will eventually build a base on
156
657041
3320
11:00
Mars. So a base is simply a way to refer to the first thing
157
660361
4440
11:04
that humans build when they get to another planet or moon in
158
664801
4560
11:09
the case of our moon. A light year. So once again Bob the
159
669361
6180
11:15
Canadian teaches English not science. But a light year is
160
675541
4600
11:20
the distance that light can travel in one earth year. So
161
680141
6240
11:26
the distance that light can travel in one year would be one
162
686381
2760
11:29
light year. That means that if you wanted to travel to the sun
163
689141
4840
11:33
if you went at the speed of light it would take you 8. 3
164
693981
3320
11:37
minutes to get to the sun. When the sun emits light it takes 8.
165
697301
5180
11:42
3 minutes for that light to get to earth. If you wanted to
166
702481
3140
11:45
travel for those of you who live in the north to the North
167
705621
3240
11:48
Star. It would take you 320 years. If your spaceship
168
708861
5440
11:54
traveled at the speed of light. It's very very far. So anyways
169
714301
3360
11:57
a light year is a unit of measure. It's a way to measure
170
717661
3200
12:00
a very long distance in space. Um and we do it by saying it's
171
720861
5040
12:05
the distance light can travel in one year. By the way we
172
725901
3240
12:09
cannot travel at the speed of light as of yet. I'm not sure
173
729141
3880
12:13
what the fastest speed a human has gone. But definitely we
174
733021
4320
12:17
have gone faster than the speed of sound. But we cannot At the
175
737341
4980
12:22
speed of light or beyond it yet. So faster than light
176
742321
4780
12:27
travel this is often something you hear about in science
177
747101
3600
12:30
fiction. In order to travel these great distances we will
178
750701
3200
12:33
need to develop a way to travel faster than light. In science
179
753901
4840
12:38
fiction they have solved this in almost every type of science
180
758741
3640
12:42
fiction. They will have hyperspace drive or hyperdrive
181
762381
3760
12:46
or faster than light engines or some way of travelling faster
182
766141
5040
12:51
than light. Um to get from one part of the galaxy or universe
183
771181
4800
12:55
to another. Of course in sci-fi there are almost always robots.
184
775981
6960
13:02
Um sometimes we call them Androids if they look like
185
782941
3160
13:06
humans. But robots would be a mechanical creature with a
186
786101
4600
13:10
computer for a brain that can do some of the same things as
187
790701
3920
13:14
humans. An android is simply a robot that has human like
188
794621
5040
13:19
qualities. So usually two legs, two arms, a face and eyes so
189
799661
5360
13:25
that they look kind of human. This would be considered an
190
805021
3260
13:28
android. Uh this would be considered an android. Um a
191
808281
3800
13:32
robot like R2D2 in Star Wars would just be considered a
192
812081
3760
13:35
robot. Actually do we call them a droid? They call them droids
193
815841
3080
13:38
don't they? Interesting. So I guess that's a Star Wars
194
818921
3520
13:42
specific reference. But my understanding is a robot is
195
822441
3120
13:45
anything mechanical with a computer brain. An android is a
196
825561
3800
13:49
robot that has some human qualities.
197
829361
4400
13:54
Ai is what we use is the short form for artificial
198
834641
4980
13:59
intelligence. So AI refers to any machine that can think. So
199
839621
5520
14:05
when we develop computers sometimes we program computers
200
845141
4440
14:09
so they can learn on their own and so that they can analyze
201
849581
4360
14:13
huge amounts of data quickly. And we sometimes say we use AI.
202
853941
4640
14:18
Currently there's a really cool AI in the world called Dali
203
858581
3840
14:22
which can make images. And so we have something that isn't a
204
862421
5200
14:27
human brain but we've programmed a computer to think
205
867621
3640
14:31
a little bit like a human and we call it AI or artificial
206
871261
4040
14:35
intelligence. A cyborg in science fiction often we have
207
875301
5640
14:40
merged technology with humans to create cyborgs. So a cyborg
208
880941
5480
14:46
is a human who has parts of their body that are robotic. So
209
886421
5880
14:52
maybe they have a robot arm or they have a computer chips
210
892301
6040
14:58
connected to their brain. Anytime a human is enhanced
211
898341
3520
15:01
with technology. We would call that a cyborg. So often in
212
901861
4680
15:06
science fiction you will run into humans who been enhanced
213
906541
4740
15:11
with technology or merged with technology and we would call
214
911281
3480
15:14
that person a cyborg. Time travel is a common thing in
215
914761
5600
15:20
science fiction as well. The ability to travel forward or
216
920361
4160
15:24
backwards in time when you talk about the movie Back to the
217
924521
3200
15:27
Future. They traveled back in time and then forward in time.
218
927721
3080
15:30
I can't remember all of the time travelling that they did.
219
930801
3000
15:33
But time travel is the ability to travel either back in time
220
933801
6000
15:39
on earth or forward in time on earth. Or forward in time and
221
939801
4480
15:44
place. Depends on the kind of machine you use. Um but often
222
944281
4700
15:48
Science fiction show will involve some element of time
223
948981
3880
15:52
travel. It's not always common. In Star Trek they have done
224
952861
4320
15:57
some time travelling. I don't think anyone in the Star Wars
225
957181
3840
16:01
movies has time traveled but in Star Trek they flew the ship
226
961021
3920
16:04
around the sun wants to travel back in time. And I think even
227
964941
4040
16:08
in one of the early Superman movies there is a little bit of
228
968981
4000
16:12
time travel. Anyways the ability to travel through time.
229
972981
3600
16:16
That would be really cool. In order to you would need a time
230
976581
3340
16:19
machine. A time machine is obviously a fictional device
231
979921
4000
16:23
that you would use to travel through time. You get in a time
232
983921
4280
16:28
machine. You punch in the date where you want to go and you
233
988201
2920
16:31
push the button. I'm talking like I've used a time machine.
234
991121
3200
16:34
And then it takes you where you want to be in time. If you
235
994321
3960
16:38
wanted to know whether I would prefer to travel back in time
236
998281
4160
16:42
or forward. I think both. If I could do some time travelling
237
1002441
3600
16:46
that would be super super fun. I would love it. So I mentioned
238
1006041
5780
16:51
faster than light travel in order for a ship to get through
239
1011821
5240
16:57
to travel quickly. But also sometimes they'll talk about
240
1017061
3760
17:00
wormholes. Where a ship flies into a wormhole in one location
241
1020821
4520
17:05
in space and it pops out. From the other end of the wormhole.
242
1025341
4280
17:09
And the distance between each end can be many many light
243
1029621
3800
17:13
years. So often when you're watching a science fiction
244
1033421
3080
17:16
movie they'll say we're going to take a wormhole to travel to
245
1036501
4120
17:20
the next galaxy and then they'll go in one end and pop
246
1040621
3120
17:23
out other and quickly travel hundreds or thousands of light
247
1043741
4060
17:27
years in the blink of an eye. Sometimes in science fiction
248
1047801
5600
17:33
they'll have a force field. There will be people who are
249
1053401
2720
17:36
fighting battles. There will be wars in the future. And you're
250
1056121
3840
17:39
watching a science fiction movie and the person is about
251
1059961
3840
17:43
to get hit by a bullet or something and it gets stopped
252
1063801
4480
17:48
by this somewhat invisible field of energy. We call this a
253
1068281
4600
17:52
force field. So this person activated their force field.
254
1072881
4240
17:57
The force field will stop bullets. It will stop
255
1077121
2840
17:59
projectiles. It will protect them. So they are protected
256
1079961
3520
18:03
because they have a force field. By the way I don't think
257
1083481
3000
18:06
this technology exists either yet. Um almost everything I'm
258
1086481
4720
18:11
talking about doesn't exist. That's why it's called sci-fi
259
1091201
2880
18:14
right? Tractor beam. So this is something that allows one
260
1094081
7560
18:21
spaceship to pull another spaceship towards themselves.
261
1101641
4160
18:25
So sometimes in a movie they'll say engage the tractor beam and
262
1105801
4200
18:30
a beam of light shoot out from their ship and it'll pull the
263
1110001
4880
18:34
other ship towards their ship. Um I think this has happened in
264
1114881
3360
18:38
almost every science fiction movie. At some point someone
265
1118241
3520
18:41
says engage the tractor beam and bring that ship closer.
266
1121761
4880
18:46
That's how captains of spaceships talk by the way. Um
267
1126641
3320
18:49
let's see here. There are many types of weapons that will be
268
1129961
6160
18:56
used in science fiction movies. Uh sometimes it's called a
269
1136121
4280
19:00
phaser. Star Trek would use phaser on in Star Wars they
270
1140401
4400
19:04
would use blasters. In old movies they might call it a ray
271
1144801
3720
19:08
gun. They might simply call it an energy weapon. This is any
272
1148521
4240
19:12
kind of weapon that does not fire bullets. But instead fires
273
1152761
4320
19:17
a beam of energy. Maybe it's a laser. Maybe it's a like a a
274
1157081
5400
19:22
bolt a laser bolt. Maybe it's I don't know. It's the future.
275
1162481
4040
19:26
It's hard to describe the projectiles. But what we're
276
1166521
3360
19:29
talking about is something that uses energy to shoot a
277
1169881
4900
19:34
destructive beam of light or a destructive laser or ray. Um so
278
1174781
5800
19:40
once again phaser is something they say on Star Trek. Blaster
279
1180581
4280
19:44
is something they say on Star Wars. Uh and Raygun if you
280
1184861
3360
19:48
watch a movie from 1950 they'll probably call it a ray gun. So
281
1188221
4760
19:52
sometimes in the future they have the ability to teleport
282
1192981
4360
19:57
from one location to another. When you use a transporter or
283
1197341
4400
20:01
when you teleport you step into a machine and then you
284
1201741
3720
20:05
disappear and it sends you Somewhere else and then you
285
1205461
5060
20:10
reappear. It's kind of wild. I would never use a transporter.
286
1210521
4080
20:14
In Star Trek they're called transporters. In other science
287
1214601
3800
20:18
fiction movies they're called teleportation devices or
288
1218401
3040
20:21
teleportation machines. Uh it's when like you see in the
289
1221441
3800
20:25
picture you disappear in one location and you appear
290
1225241
3600
20:28
somewhere else. So again if they invented this machine I
291
1228841
4840
20:33
don't think I don't think I would use it. An asteroid an
292
1233681
5180
20:38
asteroid is not a planet. It's not a star. It's just a big
293
1238861
3320
20:42
rock in space. It probably orbits something. It probably
294
1242181
4600
20:46
like we have asteroids that orbit our sun. Sometimes an
295
1246781
3800
20:50
asteroid will approach earth. But an asteroid is a giant rock
296
1250581
4520
20:55
in space. Um and if you have ever played the video game
297
1255101
4200
20:59
asteroids you would have had a chance to blow up a lot of
298
1259301
3680
21:02
asteroids. By the way we didn't talk about video games but
299
1262981
3160
21:06
there are a lot of video games. That take place in the future
300
1266141
4020
21:10
as well. Science fiction video games. A comet is just a
301
1270161
4280
21:14
collection of gases and dust and it's usually luminous. It
302
1274441
4240
21:18
usually gives off light and it usually when it approaches
303
1278681
3840
21:22
earth sometimes we can see it. So Haley's comet would be an
304
1282521
3080
21:25
example of a comet that we were able to see. Um but a comet is
305
1285601
4560
21:30
just a large collection of dust, small rocks, gases flying
306
1290161
5360
21:35
through space and giving off some light. Very Cool. A black
307
1295521
5800
21:41
hole. So there are a lot of theories about black holes. Um
308
1301321
3840
21:45
but a black hole would be a place where there is an
309
1305161
3320
21:48
extremely high amount of gravity. Such that time and
310
1308481
4720
21:53
space all compressed together. This is not a science lesson.
311
1313201
3440
21:56
If I'm describing this wrong. But a black hole in science
312
1316641
3880
22:00
fiction is usually very dangerous. Ships if they get
313
1320521
3800
22:04
pulled into a black hole they can't get back out. So a black
314
1324321
3560
22:07
hole is an extremely high area of gravity. Gravity is what
315
1327881
7820
22:15
pulls you down to earth. So a black hole has a lot of gravity
316
1335701
3960
22:19
as well. A clone. So a clone is a complete replica of one
317
1339661
7680
22:27
person or animal. So if you took my DNA and you took it to
318
1347341
4600
22:31
a lab you could make another Bob the Canadian. You could
319
1351941
4120
22:36
make a clone of me. In science fiction clones are often used
320
1356061
5400
22:41
in armies or clones are used when people want to this is
321
1361461
4520
22:45
going to sound kind of weird but in science fiction people
322
1365981
2560
22:48
sometimes they grow a clone themselves so that they can
323
1368541
4900
22:53
transfer their consciousness to a younger body in the movie or
324
1373441
5160
22:58
in the TV show foundation. The ruling people are all clones of
325
1378601
5280
23:03
each other. So a clone is when you take someone's DNA. The
326
1383881
3800
23:07
information that makes them who they are. And you grow another
327
1387681
5120
23:12
version of them I guess. Maybe I I should clone myself so I
328
1392801
4880
23:17
have more time. But then there would just be two of me. Never
329
1397681
2920
23:20
mind. I don't think that would work. Interstellar is anytime
330
1400601
4960
23:25
we talk about travelling between stars. So interstellar
331
1405561
4040
23:29
the word stellar is another word for star. So if you go on
332
1409601
4320
23:33
an interstellar voyage it means you're travelling between
333
1413921
3000
23:36
stars. If you go on an interstellar spaceship it means
334
1416921
3720
23:40
it has the ability to travel between stars. Terraforming
335
1420641
6840
23:47
terraforming is when you find a planet and then often I think
336
1427481
6720
23:54
on avatar they terraforming the planet I can't remember but
337
1434201
3200
23:57
it's when you change a planet usually to be more like earth
338
1437401
4680
24:02
so you see here this is I think they're taking a planet it
339
1442081
4240
24:06
could even be Mars and once it's terraforming it has water
340
1446321
4320
24:10
and land masses and plants and things growing on it so when
341
1450641
3160
24:13
you terraform you change a planet to be more like earth.
342
1453801
4340
24:18
That's probably why it has the word terror in it which is
343
1458141
2640
24:20
another word or earth terraforming. And I talked
344
1460781
5940
24:26
about how when we first start living on the moon or on Mars
345
1466721
4480
24:31
we will start by having a base. Once that base expands and
346
1471201
4160
24:35
people start living there we would call it a colony. A base
347
1475361
4320
24:39
is used temporarily. And people would probably only be at the
348
1479681
5480
24:45
base if they were in the military or something like
349
1485161
2640
24:47
that. A colony is when normal people start to live on another
350
1487801
4640
24:52
planet or moon. So if we had a colony on the moon. People
351
1492441
3460
24:55
would probably live in domes. I think this is supposed to be
352
1495901
3440
24:59
Mars though. Uh people would probably be get married and
353
1499341
3200
25:02
have children in a colony. Whereas a base would just be
354
1502541
3840
25:06
you know a temporary place to stay for a bit. But a colony is
355
1506381
3360
25:09
a little more serious. And in the future we might have
356
1509741
4440
25:14
holograms. Right now I am just on a flat screen. You can only
357
1514181
5080
25:19
see me from one side. But if I was a hologram I would be On
358
1519261
5980
25:25
your desk and you would be able to look at my ear and my other
359
1525241
3840
25:29
ear it would be kind of strange but in the future and in a lot
360
1529081
4720
25:33
of science fiction people will have holograms. So they'll have
361
1533801
4280
25:38
in Star Wars there's a little hologram of Princess Lea that
362
1538081
