00:00:03
Pan Am airline flight en route00:00:05
Washington to London with a00:00:07
rather unusual carry-on baggage,00:00:09
it was an atomic clock for which they even00:00:12
bought additional seats in the00:00:14
name of Mr. Klock with such an unusual cargo00:00:17
and did not fly around the earth first in00:00:19
one side then in the other direction, having spent00:00:21
about 7 thousand 600 dollars on tickets, how the00:00:24
rest of the passengers reacted to this,00:00:25
history is silent, I hope it’s not like that, but the00:00:29
most important thing is that it00:00:31
was like this anyway, so physicist Joseph Kafelya and00:00:34
astronomer Richard Keating tested the theory of00:00:37
relativity and the00:00:39
time dilation predicted by it after the flight, the00:00:41
clock readings were checked with the same ones00:00:43
that remained on the ground all the time and,00:00:45
as expected, they did not show00:00:47
the same time and that the most important00:00:49
difference completely coincided with the00:00:51
prediction of the theories; this and many00:00:53
other experiments show time and it00:00:55
really can slow down or00:00:57
speed up, one of the reasons for this speed,00:01:01
why this happens, I already told you00:01:03
in one of my episodes,00:01:04
be sure to watch it later, now it’s00:01:06
time for another reason for gravity, the00:01:09
larger it is, the stronger the hour and00:01:11
it slows down,00:01:12
by the way, it is for this reason that each00:01:14
of us has legs a little bit younger than our heads, a00:01:17
view from above, gravity is weaker from below it is00:01:19
stronger,00:01:20
therefore, by the end of life, the00:01:22
difference between the clock in the legs and the head accumulates as much as00:01:25
one millionth of a second, but if it00:01:27
seriously sounds really strange, it turns00:01:30
out that there is a deep connection between the force of gravity and time, the00:01:33
reason00:01:35
lies in the fact that we do not quite correctly00:01:37
imagine what what00:01:39
gravity is, in fact, is not a force00:01:43
of attraction and not a force at all, but the fact that00:01:46
we feel our own weight, the weight of00:01:48
other objects is in some sense00:01:50
an illusion, so now we will understand the00:01:53
true nature of gravity, because this is the only way to00:01:55
understand how it is related to00:01:57
over time, I’m sure you will really like it and00:02:00
after this video you will00:02:03
look at any watch with completely different eyes00:02:06
and at the whole world around you,00:02:08
get ready now there are a00:02:10
lot of answers to the deepest00:02:11
questions waiting for you00:02:13
building let’s go00:02:14
[music]00:02:19
I’ll say right away in all experiments on00:02:22
time dilation not the operation of the00:02:25
clock mechanism is distorted, the behavior of the00:02:27
levers and weights inside does not change, the00:02:29
flow of time is distorted at the most00:02:32
fundamental level,00:02:33
which affects any atomic00:02:36
sand mechanical clock of our00:02:38
biological son and mother’s friend00:02:40
in general, and before answering the00:02:42
main question, let’s discuss the basic00:02:45
facts about the structure of our space00:02:47
and time and let's start with the most basic,00:02:50
our world is four-dimensional, in addition to three00:02:53
spatial coordinates, conventionally length00:02:55
and width and height, there is another00:02:58
temporary one, it is practically no00:03:00
different from the others, but we are00:03:02
pathetic three-dimensional creatures cannot00:03:05
see all four dimensions are the same,00:03:08
three of them are perceived by us as00:03:09
space and one thing like time, to00:03:13
simplify, we will consider only00:03:14
one spatial and one time00:03:16
coordinate in this case, all objects00:03:19
seem to be strung on a knitting needle and can00:03:21
move only in one straight line for00:03:24
each object it will be possible to draw a00:03:26
so-called world line, it00:03:29
shows where the object is at each00:03:31
moment of time and with the help of such lines00:03:33
now we will explain everything, for00:03:36
example, an apple that supposedly fell00:03:38
on Newton’s head while the apple is hanging on a00:03:41
branch, the world line is just a straight line, but00:03:44
as soon as it breaks down, it begins to00:03:46
accelerate by the force of gravity, the00:03:48
world line becomes curved,00:03:50
this is what parabolas are like, you’re actually a world00:03:53
line you can draw for absolutely00:03:54
any object whether it’s falling or not, it doesn’t00:03:57
matter,00:03:58
and the most important thing is that you can do it a little00:04:00
easier, move the space itself under the object,00:04:02
time, and mark where it00:04:05
is, so it turns out the same thing, but I think it’s00:04:07
simpler, what I think about is that everything00:04:10
is clear here, so let’s Let's move on to the00:04:12
second fact, our 4-dimensional00:04:14
space-time is00:04:15
indirect. In 1915, Albert Einstein00:04:19
published the final assembly of his general00:04:21
theory of relativity, which gave a00:04:24
completely different view of the nature of00:04:26
gravity.00:04:27
According to his theory, massive bodies00:04:29
bend space-time00:04:31
and we perceive this as an00:04:33
attractive force, often this like this, or00:04:35
they depict space as if some00:04:37
elastic fabric bends under someone’s00:04:40
massive body and the bodies nearby seem to00:04:43
roll into this hole, as if00:04:45
they are attracted, the more massive the body, the00:04:48
more curvature, the greater the force00:04:50
of attraction, then everything is logical, here it is,00:04:53
gravity in action, as it came to00:04:55
my mind I think it’s difficult to say, but what’s00:04:58
interesting is that he studied at00:04:59
one of the best universities in those days as a00:05:02
technician in Zurich, after graduation00:05:04
no one wanted to hire him, he even00:05:06
went hungry, and only two years later, with the00:05:09
help of friends, he got a job in a patent00:05:11
office what is not exactly in the specialty and now00:05:14
the problems are the same00:05:15
where to go after college what to do00:05:17
work in the specialty or weaken a00:05:19
new one and such00:05:21
problems can be solved by the educational platform00:05:23
skillbox00:05:24
online university number 1 in Russia in the00:05:27
field of digital professions, of course, in00:05:29
physics are always needed but if your soul00:05:32
lies closer to programming00:05:34
application development, then such00:05:36
areas are needed and in demand no00:05:38
less than00:05:39
skillbox, they will prepare such00:05:41
specialists using modern techniques with00:05:43
a lot of practice, so that there are already more than 3000:05:45
thousand students entrusted with their00:05:47
education and before Einstein, their careers00:05:50
turned out well, but you will agree not all You00:05:52
can be lucky,00:05:53
so it’s never too late to master a sought-after profession,00:05:55
and even after college00:05:58
in October, Vsky Boxing hosts a free00:06:00
online conference on three areas in the00:06:03
field of digital, web design, programming and00:06:06
internet marketing, leading experts00:06:08
will talk about Internet trends in new00:06:10
professions and education using examples00:06:12
stories and cases from practice00:06:14
and will also help you choose a direction and00:06:16
reveal a couple of secrets on how to00:06:18
avoid burnout or write a cool00:06:20
resume I will repeat participation is free,00:06:22
so register using the link in the description00:06:24
and start doing exactly what you00:06:27
like, but let’s return to the curvature of00:06:28
space-time with it one00:06:31
problem is this whole analogy with00:06:32
elastic fabric and pits, it’s all00:06:35
wrong00:06:36
and only creates the appearance that you00:06:38
understand something, but in fact everything is much00:06:40
more complicated and more interesting because it’s00:06:43
not two dimensions that are bent, but all four, and the most00:06:47
important thing, including time and yes, it00:06:49
sounds like some kind of surreal thing, but time00:06:51
really can have a curvature, let’s00:06:54
figure out what it actually00:06:56
looks like in nature,00:06:57
because this is the whole point and00:06:59
this is what allows you to explain00:07:01
a lot of details, you have00:07:03
how much for this let’s slightly00:07:05
modernize our two-dimensional00:07:07
space-time, wrap it in a00:07:09
tube like this, now time goes in a00:07:12
circle like on a clock, but the most00:07:15
important thing is that00:07:17
space-time is not yet curved, it’s just a00:07:19
modernization of the flat one, but why the planes00:07:21
rolled into a cylinder are00:07:23
not yet curved, a mathematician will tell you better00:07:25
namely my friend Arthur Sharifov00:07:27
so Arthur say hello to you it00:07:30
really sounds strange that a cylinder00:07:34
is not a curved space before it00:07:36
was a plane now it is not a plane00:07:39
it is objectively curved before00:07:40
but in fact the curvature of a surface is00:07:42
not given by its position in00:07:45
space it is given by00:07:47
geometric properties but00:07:49
if we draw a square on a plane, then00:07:51
all its sides will be equal00:07:53
and all angles will be 90 degrees, but even00:07:55
if we roll you into a cylinder, these00:07:58
properties will not change, all00:08:00
sides will still be equal and the angles will still be00:08:03
90 degrees geometric properties of the00:08:06
surface when this will not change00:08:08
all the mathematics on it will continue00:08:10
to work the same way as before, which means this is00:08:12
not a curved surface;00:08:14
real curvature occurs00:08:16
when we begin to unevenly compress00:08:19
or stretch the surface, for example, like00:08:22
this, it’s00:08:23
no longer a square, it’s a trapezoid, the angles are not00:08:28
right and the sides are00:08:29
not equal, it changes itself surface geometry00:08:33
is the real curvature from00:08:37
mathematics, the curvature of space-time00:08:39
in general can lead to amazing00:08:41
things, such as the existence of black holes00:08:45
or particles that move back in00:08:48
time, we talk about this with Dima00:08:51
in the videos on my channel, of course you00:08:53
can watch it, but first00:08:56
watch this video in fact, in this00:08:58
form, our world is not yet curved, here it may00:09:01
seem that we will fall into00:09:03
some kind of time loops or maybe00:09:05
through a circle we will meet ourselves from the past, but00:09:08
this is a weak point of the analogy, so00:09:11
let’s add one more modification and assume that space-time is not00:09:14
looped but as if wound on a cylinder00:09:16
like a roll, the infinitely thin layers00:09:20
fit tightly to each other so that00:09:22
they all grow to a gigantic diameter,00:09:24
remains a fixed size, in this00:09:27
case everything is in order, the world line00:09:29
moves from layer to layer and00:09:32
we will not meet our copy from the past, the only thing is that00:09:34
now the world looks like a roll of toilet00:09:36
paper,00:09:37
but let’s at least just think less about00:09:39
it, because the fun begins, let00:09:42
’s figure out how time is bent, for00:09:44
this, let’s take another apple on the branch of00:09:46
the tree in our twisted world, they00:09:49
move in time absolutely the same, there’s00:09:52
nothing unusual here, but what if from below00:09:54
something heavy will appear, for example00:09:57
max, our planet earth turns out00:10:00
the coordinates are bent approximately like this,00:10:02
as if something is pushing them from below and the most00:10:05
important thing is that now time passes differently for the apples;00:10:12
secondly, if you expand the00:10:14
curved space, the00:10:16
world lines of the apples will be like these00:10:18
arcs, if you take identical segments, you00:10:21
can see that the top one has passed roughly three00:10:23
seconds, and the bottom one has less, which means00:10:26
his time has slowed down. It’s worth noting that00:10:29
it’s not curved like a linear00:10:31
straight cone, this is also a kind of simplification00:10:33
for the sake of ease of ponies,00:10:34
they most likely all look something like this,00:10:37
and the most interesting thing is that00:10:39
up and down the space is00:10:41
infinite, so on large scales00:10:43
the picture is something like this, and the00:10:46
heavier the body, the stronger00:10:48
the curvature occurs00:10:49
and, accordingly, the stronger the slowdown of00:10:51
time in black holes, it generally seems to be00:10:54
torn and stretches to00:10:56
infinity and keep in mind that this is only one00:10:58
coordinator, add 2 more and something like00:11:01
this will knock out the curvature of00:11:03
space-time, in fact, in00:11:05
general, this is exactly how time dilation occurs,00:11:07
but then another00:11:10
question arises: how does the force of attraction00:11:12
between bodies arise, and this is another more of a revelation, it00:11:16
turns out that this is not a fundamental00:11:18
property of our world, but simply a consequence of00:11:20
its curvature; in fact, the00:11:23
forces of gravity do not exist and this is in00:11:26
some sense just an illusion, and now00:11:29
let’s figure out exactly how it00:11:31
appears, and so in order to understand the nature00:11:33
of gravity you need to imagine00:11:35
a what if it is not there, it is turned off, if00:11:38
nothing interferes with the body,00:11:40
implementation, not gravity, not other00:11:42
stupid laws,00:11:43
it always moves in a straight line maintaining00:11:46
its speed and, in other words, flies by00:11:49
inertia for the trajectory, in this case they00:11:52
even came up with the term00:11:53
geodetic line, well, how do you00:11:55
understand whether or not always straight and00:11:57
now let's turn on gravity, a00:12:00
force appears that changes the trajectory of the body,00:12:02
tell me, but there is no force, no00:12:06
Einstein found a friend and just a00:12:08
fantastic explanation for this effect,00:12:10
and this is his main merit, he00:12:13
suggested that everything everywhere and always00:12:16
continues to move by inertia along00:12:18
geodetic lines but in four-dimensional00:12:21
space-time,00:12:22
but when it becomes curved, it00:12:24
begins to seem to us that something is00:12:26
shifting these bodies from a straight line, like some kind of00:12:30
gravitational force, look, while the00:12:32
apple is hanging, its world line is not straight00:12:35
because it is kept from falling by an external00:12:37
force from the branch, but as soon as00:12:39
the apple breaks off it is not affected by00:12:42
anything, it is free, therefore it begins to00:12:45
move in a straight line by inertia in00:12:47
space-time, which is curved00:12:49
and let's turn it back and00:12:52
see the world line has become like this,00:12:55
clearly showing that the apple is accelerating00:12:57
probably under the influence of some kind of force and00:12:59
no force of attraction it didn’t00:13:03
arise, it’s like some kind of illusion,00:13:06
the apple is flying evenly, but because of00:13:08
the curvature, it seems to us that it is00:13:11
accelerating, here we can say even more00:13:13
simply, it falls into the region of00:13:15
slow time and this00:13:16
is perceived by us as acceleration, this is how00:13:19
gravity works, this is the00:13:20
true nature of this heartless00:13:23
bastard and and secretly and the secret and it turns out00:13:26
that it is not gravity that slows down00:13:29
time, but rather, on the contrary, the slowdown of00:13:32
time, its curvature, generates a00:13:34
converting force, unexpectedly true,00:13:37
but it turns out that this is exactly how the world works,00:13:40
you can even compare it with the fact that the00:13:42
river of time carries us,00:13:43
only it happens in winter and we all00:13:45
slide along Its icy surface by00:13:48
inertia while the river is straight is00:13:50
nothing unusual, but as soon as it00:13:52
turns we see that we are being carried by00:13:55
God, it may seem to us that a00:13:57
force has arisen that moves us,00:13:59
for example the wind,00:14:01
but in fact the reason is different,00:14:03
there is no force, it’s all the fault of00:14:05
the curvature rivers are about the same with00:14:08
space time and gravity, you00:14:10
can argue00:14:11
somehow cache, because I feel the force throughout,00:14:14
I feel the weight of the object in which it00:14:16
is in my hands,00:14:17
but in fact it is not gravity,00:14:20
it turns out that we never feel it at all,00:14:22
but the fact that we in fact,00:14:24
we feel something else, for00:14:27
example, I hold a book in my palm, I00:14:29
feel heaviness, but it’s not gravity,00:14:31
it’s the electromagnetic repulsion of00:14:34
molecules and my hands are from the molecules of the book at the00:14:37
microscopic level, it looks like this, the00:14:39
molecule of the book moves by inertia in00:14:42
curved space-time and00:14:44
tend to pass through the hand as a00:14:46
result they approach so strongly00:14:48
that there is a00:14:49
noticeable repulsion of electrons and00:14:51
rather than charged 1 names00:14:53
this is what we perceive as a force but00:14:56
it is of an electromagnetic nature they are00:14:58
cavitational the same with everything00:15:00
else you feel the heaviness of your00:15:02
limbs and the heaviness of your internal organs00:15:04
However, due to electromagnetism and00:15:07
gravity, this is not a force,00:15:09
but one can say an illusion that00:15:11
arises due to the curvature of00:15:12
space-time,00:15:14
so know that the lump that you00:15:16
got when you fell from a chair is00:15:18
not due to the forces of gravity, but rather to the floor00:15:21
that stopped your natural,00:15:23
completely natural movement in00:15:25
space time, why is everything so00:15:27
complicated, it turns out to be a good question and so far00:15:32
we don’t have answers to it, but the fact that we00:15:34
were able to discover such00:15:36
patterns, you agree, this is already a00:15:38
great achievement in the battle, we have successfully00:15:41
used in practice, for example, gps and00:15:43
glonass cannot do without taking into account gravitational00:15:46
slowdown time and gravitational00:15:48
waves lensing distant galaxies00:15:50
black holes which I will00:15:52
