1
00:00:00,080 --> 00:00:04,960
ever pondered about the nature of time
2
00:00:02,520 --> 00:00:08,000
itself is it simply the ticking of a
3
00:00:04,960 --> 00:00:11,360
clock the change of seasons or is it
4
00:00:08,000 --> 00:00:13,759
something far more profound and complex
5
00:00:11,360 --> 00:00:17,000
well brace yourselves for a journey into
6
00:00:13,759 --> 00:00:19,480
the intricacies of time time as we know
7
00:00:17,000 --> 00:00:22,160
it is a fundamental concept that governs
8
00:00:19,480 --> 00:00:25,320
the very fabric of our universe but what
9
00:00:22,160 --> 00:00:27,760
is it really to understand this we need
10
00:00:25,320 --> 00:00:30,119
to dive into two main theories the
11
00:00:27,760 --> 00:00:32,840
concept of Time In classical physics and
12
00:00:30,119 --> 00:00:35,280
the concept of time in quantum mechanics
13
00:00:32,840 --> 00:00:37,760
in the realm of classical physics time
14
00:00:35,280 --> 00:00:40,920
is a constant flowing river it never
15
00:00:37,760 --> 00:00:43,719
stops never slows and never speeds up
16
00:00:40,920 --> 00:00:45,680
it's what we call absolute time it moves
17
00:00:43,719 --> 00:00:48,600
at the same pace for everyone and
18
00:00:45,680 --> 00:00:51,680
everything everywhere this was the view
19
00:00:48,600 --> 00:00:54,120
of time held by Sir Isaac Newton however
20
00:00:51,680 --> 00:00:56,600
enter the world of quantum mechanics and
21
00:00:54,120 --> 00:00:58,640
time takes on a whole new dimension
22
00:00:56,600 --> 00:01:01,199
according to Albert Einstein's theory of
23
00:00:58,640 --> 00:01:03,480
relativity time is is not absolute
24
00:01:01,199 --> 00:01:05,640
rather it is relative and can vary
25
00:01:03,480 --> 00:01:07,880
depending on the observer's speed and
26
00:01:05,640 --> 00:01:10,920
gravitational field this is what we
27
00:01:07,880 --> 00:01:13,560
refer to as time dilation now here's a
28
00:01:10,920 --> 00:01:16,920
mind-bending concept the block universe
29
00:01:13,560 --> 00:01:19,720
theory which suggests that past present
30
00:01:16,920 --> 00:01:22,640
and future all exist simultaneously in
31
00:01:19,720 --> 00:01:25,400
this model time is like a block of ice
32
00:01:22,640 --> 00:01:27,960
with every moment Frozen in place your
33
00:01:25,400 --> 00:01:30,240
past your present and even your future
34
00:01:27,960 --> 00:01:33,159
have already happened then there's the
35
00:01:30,240 --> 00:01:36,680
arrow of time the idea that time moves
36
00:01:33,159 --> 00:01:39,159
in one direction from past to Future
37
00:01:36,680 --> 00:01:41,880
this is closely linked to the concept of
38
00:01:39,159 --> 00:01:45,520
entropy the measure of disorder in a
39
00:01:41,880 --> 00:01:48,040
system in our universe entropy always
40
00:01:45,520 --> 00:01:51,280
increases giving us our forward
41
00:01:48,040 --> 00:01:53,399
direction of time but wait there's more
42
00:01:51,280 --> 00:01:56,479
the quantum world throws another
43
00:01:53,399 --> 00:01:59,520
curveball in the quantum realm processes
44
00:01:56,479 --> 00:02:01,680
can happen forwards or backwards in time
45
00:01:59,520 --> 00:02:04,520
this is a clear departure from the
46
00:02:01,680 --> 00:02:07,920
one-way Street of time we experience in
47
00:02:04,520 --> 00:02:10,280
our everyday lives so to summarize time
48
00:02:07,920 --> 00:02:12,480
is a complex and multifaceted concept
49
00:02:10,280 --> 00:02:15,000
that's far from being fully understood
50
00:02:12,480 --> 00:02:17,040
In classical physics time is absolute
51
00:02:15,000 --> 00:02:19,640
and unchanging but in the world of
52
00:02:17,040 --> 00:02:22,360
Relativity and quantum mechanics time is
53
00:02:19,640 --> 00:02:25,120
relative and can even flow in both
54
00:02:22,360 --> 00:02:28,519
directions the block universe theory
55
00:02:25,120 --> 00:02:31,040
suggests all moments in time exist
56
00:02:28,519 --> 00:02:33,599
simultaneously while the arrow of time
57
00:02:31,040 --> 00:02:36,720
points out that time flows from past to
58
00:02:33,599 --> 00:02:39,319
Future due to increasing entropy yet in
59
00:02:36,720 --> 00:02:42,200
the quantum realm time can seemingly
60
00:02:39,319 --> 00:02:44,560
reverse its course remember these are
61
00:02:42,200 --> 00:02:46,760
just theories and interpretations based
62
00:02:44,560 --> 00:02:49,120
on our current understanding as our
63
00:02:46,760 --> 00:02:52,640
knowledge of the universe expands our
64
00:02:49,120 --> 00:02:55,080
concept of time May evolve too time it
65
00:02:52,640 --> 00:02:57,319
seems is as mysterious as it is
66
00:02:55,080 --> 00:03:00,250
fundamental isn't it fascinating to
67
00:02:57,319 --> 00:03:03,379
ponder on the Enigma that is time
68
00:03:00,250 --> 00:03:03,379
