Time Dilation feat. Paolul - Physics 101
00:18.0
Kaya for today's video mga kamatis mga kaibigan
00:22.2
time dilation. Time dilation
00:24.4
happened when time slows down
00:26.4
for an observer moving close
00:28.2
to the speed of light. Sa Tagalog
00:30.4
ang ibig lang sabihin ito
00:32.2
habang bumibilis ang
00:34.0
iyong takbo, papalapit ng papalapit
00:36.6
sa speed of light, bumabagal
00:40.4
Ang speed of light mga kamatis
00:42.2
mga kaibigan denoted by the
00:44.2
small letter C is
00:58.2
the fastest moving
01:00.1
fighter jet na ngayon
01:04.7
which moves at the
01:08.3
meters per second.
01:10.3
Ibig pong sabihin the speed of light
01:16.2
than the fastest fighter jet
01:18.0
we have right now. Now, weird
01:20.2
things happen when an object approaches
01:22.1
the speed of light. In fact,
01:24.3
this is the topic of discussion
01:26.2
ni Albert Einstein.
01:28.2
Special Theory of Relativity
01:30.3
Opo, yung Special Theory
01:32.7
of Relativity is all about
01:34.8
the discussion of the
01:36.4
interactions of objects approaching
01:38.6
the speed of light or approaching
01:40.5
what we call relativistic
01:42.6
speeds. Pero since mahabang
01:44.8
kwentuhan niyang General Theory
01:46.7
at Special Theory of Relativity
01:49.0
ni Albert Einstein, siguro
01:50.7
yan ang next topic natin
01:52.8
sa susunod na video. Let me
01:54.8
know dyan sa comment section kung gusto
01:57.9
Opus Dei ng isa sa mga
02:00.2
bantog na sayantipiko sa modernong
02:02.5
panahon. So, paano ba gumagana
02:04.5
ang time dilation? Let us
02:06.2
visualize time dilations in
02:08.2
object we can perceive or yung
02:10.3
naiintindihan ng ating mga senses.
02:12.9
At karoon tayo ng munting
02:14.4
thought experiment. Kunwari,
02:16.7
nakipagkulab ako kay Kitty
02:18.5
at kay Kai, isa sa mga sikat
02:20.6
na kambal na tiktokerist
02:22.3
dito sa ating bansa. Tapos,
02:24.1
hiniram ko yung spaceship ni Nick
02:27.9
spaceship ni Nick Makino, let's assume
02:30.0
that it can move close
02:32.0
to the speed of light. Sasabihin
02:34.3
kong ganun kay Kitty, yo Kitty
02:37.6
eto yung spaceship
02:40.0
ni Nick Makino at bumili ka ng
02:41.9
suka sa Planet X.
02:44.1
Medyo malayo yung Planet X.
02:48.1
trillion kilometers away
02:50.1
from Earth. It would
02:52.0
take light one year para
02:54.0
makaabot dito sa planetang ito.
02:57.9
trillion kilometers is a significant
03:00.3
number kapag usapan natin
03:02.1
is traveling to great, great
03:04.1
distances. Yung malalayo talaga.
03:06.6
Alam natin that the speed
03:08.2
of light in a vacuum ay constant
03:10.3
or di nag-iiba. We can then
03:12.3
compute for the distance traveled
03:14.2
by light in a year. Hence,
03:16.3
in a year, light travels
03:20.6
trillion kilometers. We can
03:22.3
call this light years.
03:24.3
So, yung sukat po na light years
03:27.9
Hindi po yan. Hindi po yan oras.
03:30.1
Malinaw po ba? So, kapag narinig
03:32.0
nyo yung mga science show na
03:33.4
sinasabi yung salitang light years,
03:35.9
they are just referring to the distance
03:37.9
traveled by light in a year, which is
03:40.0
9.5 trillion kilometers.
03:42.2
So, balik tayo sa
03:43.9
ating thought experiment. So, ang
03:45.8
round trip ni Kitty would take her
03:50.2
Papunta pa balik para bumili
03:52.0
ng suka sa Planet X.
03:54.0
Buti na lang, yung spaceship ni Nick Makino
03:56.0
can move or travel
03:59.8
of light. But this is where it gets
04:01.8
weird. Objects moving at
04:03.7
the speed of light will experience
04:05.7
what we call time dilation.
04:07.7
So, pag tumingin sa orasan, si Kitty
04:09.8
sa kanyang spaceship, parang normal
04:12.0
lang. Pero, yung naiwan
04:13.7
niyang kapatid dito sa Planet Earth
04:16.0
would experience time
04:18.0
very differently.
04:19.7
According to the special relativity
04:21.7
of Albert Einstein,
04:24.0
they will experience what we call
04:26.0
time dilation. Ang isa't
04:27.9
ang oras dito sa Earth
04:29.5
would be less than 9 minutes sa spaceship.
04:32.5
24 hours sa spaceship
04:34.3
would be more or less
04:35.9
35 minutes sa spaceship.
04:37.9
At 1 year sa spaceship
04:40.2
would be 8 years here on.
04:42.7
So, papunta pa balik,
04:44.1
2 years para dun sa spaceship.
04:46.4
Pero, para dun sa mga
04:48.0
naiwan sa Planetang Earth,
04:52.0
ang makakalipas sa papunta
04:54.2
pa balik ni Kitty
04:55.6
para bumili lang ng suka.
04:57.9
Kaya, for example,
04:59.7
example lang ha, hindi ko sinasabing
05:01.7
eto talaga yung edad nila.
05:03.5
Kung ang edad ni Kitty nung umalis
05:05.9
siya ay 40 years old,
05:07.8
pagbalik niya, 42
05:09.6
lang siya. Pero, since
05:11.8
si Kakay ay naiwan dito sa Planet
05:13.9
Earth, pagbalik nung kapatid
05:16.0
niya na si Kitty, 56
05:17.6
years old na si ate
05:19.9
Kakay mo. Same age nung
05:21.9
umalis, different age nung
05:23.9
bumalik. That is the effect of
05:25.8
time dilation, mga kamatis, mga kaibigan.
05:27.9
This is the famous thought
05:29.9
experiment called The Twins
05:31.9
Paradox. Actually,
05:33.9
this concept was greatly explored
05:35.9
in a movie called Interstellar.
05:37.9
So, kapag may time kayo,
05:39.9
you should watch it. So, mga kamatis,
05:41.9
mga kaibigan, do you want more
05:43.9
science video? Let me know dyan sa
05:45.9
comment section down below. For now,
05:47.9
I bid you farewell. Gege mga lods!
