00:00:00
It seems that we just agreed that
00:00:02
moving faster than the speed of light in a
00:00:04
vacuum is impossible, it may be
00:00:07
associated with traveling Back in time,
00:00:09
that is, to the past, and This seems to
00:00:12
cause all sorts of Paradox and all that, in
00:00:15
general, modern physicists are not comme il faut,
00:00:17
but then scientists come and say,
00:00:20
but let’s come up with
00:00:22
Tachyons particles that travel faster than
00:00:25
light and can move Back in time
00:00:28
and we’re like, well, great thanks. On the one
00:00:33
hand, you never know what several scientists
00:00:35
have come up with if there is a more or less
00:00:37
general consensus, but on the other hand, this has
00:00:39
happened more than once in history of science that
00:00:41
some idea
00:00:43
was first rejected by the majority and then almost staged a
00:00:45
revolution in science. Maybe with tachyons,
00:00:48
too, we are just not ready for this yet.
00:00:51
This word has been known to science fiction for a long time; the
00:00:54
guardians of the tachyons did not allow the
00:00:56
Manhattan doctor
00:00:58
to see the future at a certain moment. They in the dune at the base of
00:01:02
Isaac Asimov in the start tracks there is beer in general in many places
00:01:06
often in Wikipedia in an article about
00:01:09
some scientific concept there is a section
00:01:11
On the use of this concept in
00:01:13
fiction or cinema, but
00:01:16
this is not just such a section, but a
00:01:18
whole separate article, but still what
00:01:21
What are tachyons from the point of view of science? What
00:01:24
paradoxes are associated with them and how can they
00:01:26
be solved? Can these particles
00:01:28
traveling into the past exist and
00:01:31
what attempts have been made to find them and why do
00:01:34
scientists need them? And what kind of
00:01:36
tachyon water is for sale? I have been
00:01:39
asked more than once to make a video So today we’ll talk
00:01:41
about all this and let’s talk about
00:01:49
black holes, there are never too many
00:01:52
black holes, you love black holes, read about them
00:01:55
Watch the video, but sometimes you want
00:01:57
something more detailed,
00:01:59
some kind of university lecture. There are whole courses of lectures about
00:02:02
black holes and, in principle, on the Internet
00:02:04
in astrophysics
00:02:06
Yes, here’s a small problem, they are
00:02:08
usually in English, but Yandex.Browser
00:02:11
solves this problem with translation, this
00:02:13
issue is published with the support of Yandex,
00:02:16
look, download Yandex.Browser,
00:02:18
launch and enter the request black holes
00:02:21
lecture Yes, enter directly in Russian,
00:02:23
go to the video tab and click filter
00:02:26
with voice-over translation
00:02:28
now we see videos on the selected topic
00:02:31
in foreign languages ​​And this is not only
00:02:33
English but also German French
00:02:35
Italian Spanish you select a video and
00:02:38
watch it with Russian translation and
00:02:41
After turning on the filter, the videos
00:02:42
are shown with translated titles
00:02:44
here is the video in the original without translation
00:02:52

00:03:12
So tachyons are particles for now
00:03:15
exclusively hypothetical, which I will
00:03:17
always emphasize always move faster than the
00:03:21
speed of light in a vacuum tachyons are not
00:03:24
just one specific particle, in theory
00:03:26
they can be different, but what unites them
00:03:29
is superluminal movement and
00:03:31
some other properties.
00:03:33
Modern physics and the special theory of
00:03:35
relativity in particular tell us
00:03:38
that nothing can move faster than the
00:03:40
speed of light in a vacuum, in fact,
00:03:43
not even that
00:03:45
nothing that has mass
00:03:47
in general can exceed it, but simply achieve it, I have spoken about the speed of light more than once in my videos
00:03:50
and I even had
00:03:51
separate videos dedicated to it,
00:03:54
there are usually two main explanations in
00:03:56
simple language without formulas Why it is impossible to achieve the
00:03:59
speed of light for a massive object
00:04:00
one concerns mass and in a
00:04:03
simplified form it sounds like this. According to the
00:04:05
special theory of relativity, the
00:04:07
faster an object moves, the greater its
00:04:09
mass, and when the speed of an object
00:04:11
relative to the observer approaches the
00:04:14
speed of light in a vacuum, its mass
00:04:16
begins to tend to infinity; in
00:04:18
order to continue accelerating it, an
00:04:20
infinite amount of energy is required,
00:04:23
this is like a problem
00:04:27
we have nowhere to get infinite energy; the second explanation is
00:04:29
related to time; Einstein’s
00:04:31
space and time are united into a
00:04:33
single space, time, and we always
00:04:36
move not only in space but also
00:04:38
in time, and the faster we
00:04:40
move in space, the slower we
00:04:42
move in time at rest, the truth of
00:04:45
absolute rest we cannot achieve it in
00:04:47
time, we move at the speed of light.
00:04:50
Now, if we start moving at the
00:04:52
speed of light in space, then time
00:04:55
should stop completely for us, which is
00:04:58
also a problem, of course, it’s all
00:05:01
very simplified, but the main thing is that we not only
00:05:04
exceed, but even reach the speed We
00:05:06
can’t light, but at the speed of light
00:05:09
we have mass-free particles moving
00:05:12
leons and possibly gravitons, if they
00:05:16
exist, from what I have already said,
00:05:18
it is clear that the problem for superluminal
00:05:20
movement is mass, what then
00:05:22
should the mass of tachyons be, you might
00:05:25
think that it should be
00:05:27
negative, sounds of course it’s very
00:05:29
strange how something can have a mass of
00:05:32
-5 kg, but in physics the concept of
00:05:35
negative mass and negative
00:05:37
energy are quite considered and we
00:05:40
even talked about them once in a video
00:05:41
about the warp engine, I said that
00:05:44
especially the first versions of calculations for
00:05:46
engines that bend
00:05:47
space time and thereby
00:05:49
move from one point of the Universe to
00:05:51
another faster than the speed of light required
00:05:54
for this negative mass an object with
00:05:56
such a mass would behave strangely and if
00:05:59
we pushed it it would On the contrary
00:06:00
be attracted in later versions of
00:06:03
calculations for a warp engine true
00:06:05
managed to get rid of the need
00:06:06
to use negative mass, which
00:06:09
made it at least a little more
00:06:11
realistic, but with tachyons everything is a little
00:06:13
different and even more strange, the
00:06:17
tachyon hypothesis implies an
00:06:20
imaginary mass, what in general is this in
00:06:24
English such a term imagineerings
00:06:27
literally imaginary mass, we
00:06:30
say imaginary mass, a mass that is
00:06:32
represented by a purely imaginary number,
00:06:35
again, this is not some kind of joke from
00:06:37
the nineties, but a completely normal
00:06:39
mathematical term, purely imaginary number,
00:06:42
we won’t dig deep
00:06:44
into mathematics now and deal with imaginary
00:06:47
numbers about them on YouTube. By the way, there are a whole
00:06:49
playlists with 12 short videos, if
00:06:51
you’re interested, I’ll leave a link in the description
00:06:53
I will say that no matter how strange they sound, you
00:06:56
shouldn’t neglect them, although especially
00:06:59
their English name for the
00:07:02
number can make you take them
00:07:06
lightly. But this is rather, in a
00:07:08
sense, just not a very good name
00:07:10
for a long time, people used only
00:07:13
natural numbers for 1 2 3 10 100 and so
00:07:16
on, but at some point this was not
00:07:18
enough and people began to use
00:07:20
fractions. And they also introduced the number 0 and
00:07:23
negative numbers. The same negative
00:07:25
numbers in mathematics were not accepted for a very long time,
00:07:27
how could there be something less
00:07:29
than a few today
00:07:33
negative numbers do not bother anyone
00:07:35
even though they don’t seem to reflect anything
00:07:37
in physical reality, however, they are very
00:07:39
convenient to use, say, to
00:07:41
indicate a negative balance on
00:07:43
an account, and imaginary numbers are another
00:07:46
such extension and it arose when
00:07:48
trying to solve some equations; the
00:07:50
imaginary unit is written with the symbol Ai and
00:07:53
ai is equal to square the root of minus
00:07:56
one or you can write
00:07:59
equal to Minus one What is the square
00:08:03
root of a negative number or
00:08:04
in other words what number must be
00:08:07
multiplied by itself to get a
00:08:10
negative result 2 x 2
00:08:14
= 4 minus 2 multiplied by -2 is also equal to 4
00:08:19
it doesn’t matter we multiply ourselves
00:08:22
positive or negative number,
00:08:24
the result is always positive.
00:08:27
Therefore, if we take the simplest
00:08:29
example, the equation x² + 1 = 0 looks
00:08:34
like it has no solution so that after the
00:08:37
equal sign there is 0 x² should be equal to -1
00:08:40
And as we have just seen from us
00:08:43
it will not be possible to multiply any ordinary
00:08:45
number by itself to get -1, this is where
00:08:48
imaginary numbers are needed. When
00:08:51
fractions appeared on the number line,
00:08:53
additional numbers appeared between the integers. When
00:08:57
negative numbers appeared, the number line
00:08:59
began to continue to the left, and the introduction of
00:09:01
purely imaginary numbers adds, as it were, a
00:09:03
second dimension up and down from the straight line
00:09:06
and once again, no matter how strange it all
00:09:09
looks. This is not just an invention. The radius is
00:09:12
now imaginary numbers are used in
00:09:14
certain branches of physics, including
00:09:16
quantum mechanics. Well, in the end, were
00:09:19
n’t we just making up all the numbers? Well,
00:09:23
here the truth is, some would argue as I
00:09:25
already said, if you are interested in
00:09:26
understanding the topic in more detail in the description, I will
00:09:28
leave a link to cool videos for
00:09:30
us now the main thing is that tachyons are
00:09:33
particles with imaginary mass, the term
00:09:36
tachyon itself was proposed by Gerald
00:09:37
Feinberg in a 1967 article, a
00:09:41
discussion about particles capable of
00:09:43
traveling faster than the speed of light in a
00:09:45
vacuum there were before, but it was then that
00:09:47
the word tachyon from the
00:09:50
Greek Tachy fast was first heard, considering that the
00:09:53
special theory of relativity
00:09:54
prohibits movement faster than the speed of
00:09:57
light in a vacuum, he
00:09:59
circumvents this prohibition in the article by the fact that these particles
00:10:01
arise in a field with an imaginary mass ID
00:10:04
particles with similar properties too
00:10:06
appeared
00:10:07
for example in this article of 1962, limiting the
00:10:12
understanding that it is impossible to accelerate
00:10:13
particles to speeds above light,
00:10:16
it was proposed to get around the fact that such
00:10:18
particles are immediately born. At such a
00:10:21
speed, one of the modern
00:10:22
dominant physical theories is
00:10:25
quantum field theory. Let me remind you that its
00:10:27
basic principle is that
00:10:29
all known us Elementary particles
00:10:31
This is not just how they like to draw them in
00:10:34
illustrations. Very small balls
00:10:37
permeate the entire universe with fields at every
00:10:40
point in the Universe, this field has a
00:10:42
certain value, and a particle is nothing
00:10:45
more than a disturbance in these fields, and
00:10:47
each elementary particle must
00:10:49
correspond to its own field, photons - this is a
00:10:52
disturbance in the electromagnetic field,
00:10:53
electrons in an electron quark in a
00:10:57
quark, and so on,
00:10:59
if there are particles, then there must be a field,
00:11:03
or vice versa, the truth is that with stachyonic fields
00:11:07
everything is a little more complicated; the particles themselves are
00:11:10
only hypothetically so far, more in the form in
00:11:13
which Feinberg described them, in theory they
00:11:15
cannot exist And if such
00:11:17
disturbances occurred in the fields, they would
00:11:20
be unstable, but the phrase
00:11:22
tachyon field is sometimes applied to such a
00:11:25
well-known field as the Higgs field, this does not
00:11:28
mean that the Higgs Boson is a
00:11:30
tachyon and it certainly does not move faster than
00:11:32
Light. However, the Higgs field is sometimes
00:11:35
said to have it has an imaginary mass and in a
00:11:37
certain sense is called tachyon
00:11:42
Well, let's assume that tachyons do
00:11:44
exist and if so then they must
00:11:47
have very strange properties;
00:11:49
we have already mentioned superluminal movement,
00:11:51
but there are other interesting details
00:11:54
when considering tachyons. Particles
00:11:57
that can only move slower than the
00:11:59
speed of light in a vacuum, that is, the
00:12:01
particles we are familiar with are called rhodions;
00:12:04
between them there are also Particles that in a vacuum
00:12:07
always move at the speed of light
00:12:08
luxons. For example, photons, if ordinary
00:12:12
matter is added to particles, what will happen
00:12:15
naturally, this substance will accelerate,
00:12:18
push the bed, it will go faster
00:12:23
if we add energy to them, they will
00:12:27
slow down. That is if we were pushing a
00:12:30
tachyon cart it would slow down for
00:12:34
ordinary matter the upper
00:12:36
speed limit is the speed of light, in order to achieve it
00:12:39
you need infinite energy the
00:12:42
speed of light is, on the contrary, the lower
00:12:44
speed limit to slow down
00:12:46
the tachyon to the pitiful speed of light again
00:12:49
you will need infinite Energy and the
00:12:52
lower the tachyon energy the the greater its
00:12:54
speed is, the closer the energy is to
00:12:58
zero, the closer the speed is to infinity. It’s
00:13:01
still very strange. What the tachyon
00:13:04
would look like for us if we could
00:13:07
observe it, because of superluminal
00:13:09
motion, we wouldn’t be able to see it on its
00:13:11
way to us. But that’s when it gets there if it
00:13:13
reached us, we would see how the tachyon
00:13:15
is divided into two separate images,
00:13:18
one of them is an instantaneous
00:13:20
tachyon and the other is disappearing in the
00:13:23
opposite direction, and finally,
00:13:25
let's talk about the strangest
00:13:27
property about Travel to the past if a
00:13:31
massive object cannot reach
00:13:32
the speed of light because it will
00:13:34
means stopping time, what
00:13:37
happens If this speed is even
00:13:38
exceeded, then time will begin to flow
00:13:42
in general, as a rule, when discussing
00:13:43
superluminal movement,
00:13:45
the statement often comes up that this
00:13:47
can lead to travel into the past, you
00:13:49
can find a detailed explanation for this with
00:13:52
spatial time diagrams,
00:13:54
light cones, and so on But for
00:13:57
us, the fact itself is important for now, and it is believed that
00:14:00
tachyons for some observers will
00:14:02
move back in time and this
00:14:05
automatically causes various
00:14:06
products that are associated with traveling
00:14:08
into the past and the presence of these paradoxes is one
00:14:11
of the main reasons why many scientists are
00:14:13
extremely skeptical about tachyons,
00:14:15
I will not retell the same well-
00:14:17
known products like Paradox and
00:14:19
Grandfather. And as an example, let’s take a
00:14:21
version of paradoxes that uses
00:14:23
tachyons. The problem with traveling
00:14:26
Back in time is that they violate
00:14:28
one of the fundamental principles, the
00:14:29
principle of Causality, the result cannot
00:14:33
precede the action, the speed of light is
00:14:36
also called speed
00:14:37
Causality, for example, a hypothetical device was invented: an
00:14:42
anti-telephone device that sends
00:14:45
signals to the past. Let's take a closer
00:14:47
look at the version of the tachyon paradox
00:14:49
that I found in John de
00:14:51
Norton's article. For this paradox, we need to
00:14:53
assume the existence of tachyons,
00:14:56
a device capable of emitting and
00:14:58
receiving them, as well as a tachyon mirror
00:15:01
that can reflect tachyons Let's
00:15:03
imagine a spaceship on
00:15:06
which there is a tachyon emitter and the
00:15:08
ship is completely robotic; it is
00:15:10
programmed to fly strictly along a
00:15:12
certain trajectory and release
00:15:14
the tachyon at a strictly defined moment in a
00:15:17
certain direction, and again, in a
00:15:19
certain way, react to the
00:15:21
reception of the tachyon with numbers 1 and 2; this
00:15:24
figure shows two moments in time.
00:15:26
The ship flies in moment one nothing
00:15:29
happens But in moment two it
00:15:32
emits a tachyon which flies and
00:15:35
is reflected from a tachyon mirror placed in advance in a
00:15:37
special place,
00:15:39
the mirror is directed to reflect
00:15:41
Tachy which, as we remember, can
00:15:43
move Back in time the tachyon
00:15:45
is reflected flies into the past and
00:15:48
meets again with the ship at moment 1, the
00:15:50
tachyon detector on the ship
00:15:52
registers a particle at moment 1 and
00:15:55
the trick is that we have also
00:15:57
programmed the ship. So if
00:16:00
the detector registers a tachyon, the ship
00:16:03
self-destructs, it turns out that at the
00:16:06
moment one ship catches the tachyon and
00:16:09
destroys itself and it can no longer fly
00:16:12
further to at moment two to emit
00:16:14
a tachyon it means at moment one ship does not
00:16:18
receive tachyons the ship is not destroyed.
00:16:21
It can again fly to moment two and
00:16:25
again emits a tachyon and
00:16:28
is again destroyed at moment one and so on
00:16:32
from all this an obvious
00:16:35
contradiction follows: the ship
00:16:38
does not receive tachyon only if it receives
00:16:41
tachyon we can also express this So that the
00:16:44
ship both receives and does not receive a tachyon,
00:16:47
we can modify this tachyon Paradox a little
00:16:49
if we want to get rid
00:16:52
of the need to use a mirror and
00:16:54
instead just use Two
00:16:56
ships, but the essence and conclusions remain the
00:16:59
same and this is a big problem especially if
00:17:02
at least how many - Seriously try to
00:17:04
consider tachyons What are the solutions to
00:17:06
this paradox? Well, the simplest thing is that
00:17:09
tachyrons do not exist, there are no tachyons, there is no
00:17:13
paradox, but still, if we are trying
00:17:15
to push the boundaries of modern science
00:17:17
to build new hypotheses, such a solution
00:17:20
may perhaps be too radical,
00:17:22
if we are still trying to admit their
00:17:24
existence, then there is another solution
00:17:26
that if tachyons exist but we
00:17:29
can’t control them in any way, we can’t choose
00:17:32
how and when to emit or receive a tachyon
00:17:34
and all this happens only by chance.
00:17:36
If so, then we can’t build the
00:17:39
conditions under which this Paradox will arise.
00:17:41
Or maybe we just couldn’t to
00:17:43
see the difference between sending and
00:17:46
receiving a tachyon, there is also a version that
00:17:48
tachyons do not interact in any way with
00:17:50
ordinary matter and they cannot be
00:17:52
registered and observed, that is,
00:17:55
they may exist, but we have no way of
00:17:57
knowing this. Moreover,
00:17:58
these options allow us to use them to send signals to the past
00:18:01
not to arise as a
00:18:02
paradox but to exist as a tachyon But
00:18:05
this is all a thought experiment,
00:18:06
reasoning, but what about the already
00:18:09
unthoughtful but real experiments and
00:18:11
attempts to detect tachyons After all, if
00:18:14
we detected a particle with the properties of a
00:18:16
tachyon This would be a completely different
00:18:18
conversation
00:18:21
How is it possible to detect such a
00:18:23
particle Well, that’s how at least not just, but there are
00:18:27
some ideas, one of the main ones is
00:18:29
related to the Vavilov Cherenkov effect
00:18:31
or Cherenkov radiation Remember I
00:18:34
said that nothing can move
00:18:36
faster than Light But no, more precisely, it was not for
00:18:41
nothing that I almost always added a clause with the
00:18:44
speed of light in a vacuum from time to
00:18:46
time in The media appears with
00:18:48
news articles saying that scientists were
00:18:50
allegedly able to exceed the speed of light in
00:18:52
experiments, naturally, in fact, there is
00:18:58
no talk of any violation of the laws of physics, but the stories there are
00:19:00
different, one of the reasons for such articles may
00:19:02
be this is the maximum
00:19:04
physical limit in terms of speed, the same
00:19:07
almost 300 thousand kilometers per second is in a
00:19:10
vacuum and it’s probably no secret to many of you
00:19:13
that when light enters
00:19:15
some transparent medium it seems to
00:19:17
slow down and then how much it
00:19:20
changes, we are told by such a parameter as the
00:19:21
refractive index in my recent
00:19:24
video about the speed of light I gave such
00:19:26
examples: glass has a refractive index of
00:19:29
1.5, which means the light in it slows down by one
00:19:33
and a half times and the speed of light is no longer 300
00:19:35
but 200 thousand kilometers per second inside
00:19:38
the Diamond, light generally slows down by as much as two
00:19:40
and a half times and there were laboratory
00:19:42
experiments in which light In general, it was
00:19:43
practically possible to stop the light in that
00:19:46
video. I also gave an explanation of
00:19:47
why this happens, including
00:19:50
common incorrect ones. But here’s
00:19:52
the funny thing: scientists cannot accelerate particles
00:19:54
with mass to 100% of the speed of light. However,
00:19:57
they can easily accelerate them to 99, 99 and
00:20:01
so on percent and even regularly
00:20:03
do this with an accelerator of their particles and
00:20:06
some of these particles, when they
00:20:07
find themselves in a medium, do not slow down as
00:20:10
much as photons, it turns out that such
00:20:13
accelerated particles in a medium can
00:20:15
move faster than photons
00:20:17
and it turns out to be faster than light, that
00:20:20
is, like a headline I didn’t lie about the news about
00:20:22
moving faster than Light, but in
00:20:24
fact these particles do not exceed the
00:20:26
fundamental limit of 300 thousand
00:20:28
kilometers per second, their speed is
00:20:30
still lower. It’s just higher than the very
00:20:33
slow photons in the medium, this is the first thing
00:20:35
further if such particles are also
00:20:38
charged and move faster than light in
00:20:40
special environment They emit that same
00:20:43
Cherenkov radiation Well, there is
00:20:46
an assumption that something similar can
00:20:48
occur from tachyons, they act as
00:20:50
faster particles instead of a dense
00:20:53
medium, almost the complete vacuum of space and
00:20:56
tachyons can emit Cherenkov
00:20:57
radiation, if it is detected, then
00:21:00
you can indirectly detect these cheons
00:21:02
trying to do this there have already been, but so far
00:21:05
to no avail, the question is, if they exist,
00:21:08
are tachyons some kind of
00:21:10
fundamentally new particles unknown to us,
00:21:12
or can they be already
00:21:14
known
00:21:16
in the case of the second two options?
00:21:18
Several types of neutrinos have been proposed for the role of tachyons, of
00:21:20
which we know that there are a
00:21:23
huge number of them passing through
00:21:25
us right now, in general, they are now
00:21:28
considered not massless and they
00:21:30
move at a speed close to light but not
00:21:32
light speed, but there were precedents
00:21:34
when the discovery of
00:21:36
superluminal neutrinos was announced. And if this
00:21:39
turned out to be true, then they would be suitable for the
00:21:41
role of tachyons in 2011, a group of scientists
00:21:45
announced detection at the
00:21:47
Opera detector in a joint experiment of Cern and the
00:21:49
Grand Sasso National Laboratory of a
00:21:51
neutrino that seemed to move
00:21:54
faster than the speed of light in a vacuum. This
00:21:57
story made a lot of noise in the media; it
00:21:58
was not obviously received skeptically by the
00:22:01
scientific community. Well, as it turned out, it was
00:22:03
not in vain that after a series of checks it turned out that the
00:22:06
anomalous result was to blame
00:22:08
equipment defects So
00:22:11
no tachyons here either Unfortunately, there were,
00:22:14
of course, other experiments with different
00:22:15
approaches, but there is no need to list them, after all.
00:22:18
So far, none of them have shown any
00:22:20
confident positive results from the
00:22:23
point of view of experimental science. There is
00:22:24
no data yet in favor of the
00:22:26
existence of flying particles throughout
00:22:28
the Universe faster than the speed of light in a
00:22:30
vacuum However, this does not stop
00:22:32
theorists and they are trying to apply the concept of tachyons
00:22:35
in various fields of physics,
00:22:36
astrophysics and cosmology and are trying to
00:22:39
develop the theory of tachyons themselves; they
00:22:41
describe the possible interaction of
00:22:43
tachyon fields with black holes;
00:22:45
they consider tachyons as
00:22:47
candidates for the role of dark matter and
00:22:50
dark energy they are looking for their traces in
00:22:52
supernova remnants and even discussing the possibility of
00:22:55
the existence of such strange objects
00:22:57
as tachyon stars. And of course, charlatans often tried to parasitize on such
00:23:01
cool-sounding hypotheses;
00:23:05
any unknown [ __ ] that
00:23:08
sounds like magic and in fact is what
00:23:10
these charlatans, for example, try to
00:23:13
explain with quantum effects
00:23:17
remains How do you like, for example, water
00:23:19
charged with tachyons is naturally
00:23:22
miraculous and naturally
00:23:24
rejuvenating, this is all cool, of course
00:23:27
scientists have not been able to find them for decades, and
00:23:30
enterprising guys are already putting them in their
00:23:32
water, in general, nothing new
00:23:35
at all, of course, scientific
00:23:37
hypotheses and theories are not always confirmed,
00:23:39
which naturally cannot every idea
00:23:42
immediately hits the mark, this is an important part of the
00:23:45
scientific process, maybe tachyons will never
00:23:47
be found, but as often happens,
00:23:50
they can discover a lot of things in the process,
00:23:52
push the boundaries of science, and in science, even a
00:23:56
negative result is also a result,
