Physics meets Guitar Pedal – Interferometer Guitar Pedal
Guitar pedal recreates the Michelson-Morley experiment which was used to evidence a supposed fixed speed of light and validate Einstein theory, therefore propelling science, military and religion in a particular direction. Definitely takes the cake for Most Interesting guitar pedal to-date!
Good explanation. Note that Michelson had Jesuit brother. Morley came from military. So at yet another pivotal point in science (or psyence) there was again military and religion, hand-in-hand, like all down through eternity. Beware the likely manipulations. Main purpose of Jesuits has always been to do away with Protestant religion, Christianity and Jesus, and instead insert the Roman Catholic Pope as necessary intercessor to God (and therefore logically if not righteously due a tithing). The motive is self-evident. This segues beautifully into delve back into roots of psyence, science, and attempt to direct future course of humanity away from Protestantism and back to Papacy.
This segues to interesting aspects of early modern science influenced by military and religion: https://wp.4sci.org/2025/03/chatgpt-caught-in-more-egregious-lies-of-omission/
OPERATION: One of the LASER relfecting mirrors is attached to a mini-speaker, the physical movement of which causes optical distortions in interference pattern (and thus resistance in optical detector); this variance applied in electronic circuitry to adjust gain, phase shift time-delay and/or EQ filtering, etc. The exact schematic is not given. “The harder I play, the more overtones I get.” 9:35 in
ABOVE: Michelson-Morley whirling table. Physical movement was thought to influence relative motion versus “aether”, the supposed medium of light and electromagnetics; such relative motion being made apparent in variations of visible interference patterns. No noticeable changes were observed, indicating physical motion vs aether did not matter to speed of light, or in other words that speed of light was constant. This determination was pivotal in the validation and subsequent laudation of Einstein and Relativity as the way forward in scientific (and thus religious) reality.
I don’t think the Aether moves, and I don’t think there is any ball-like planet to move. Instead, remove the T from PLANET and get to the far more likely PLANE, fixed, immovable. If neither Aether nor our physical world moves, then adjusting the table in any orientation, stopping it, and then taking a measurement will always show ‘negative’ result, indicating fixed speed of light. However, if you look for changes in interference pattern while the table is moving I suspect the outcome would be ‘positive’ indicating an influence of aether upon light. Such a positive finding would not prove nor disprove stationary plane. Stationary plane was discarded as whirling globe hurling through space was presupposed. In that way, the experiment was ultimately a well-orchestrated sham designed to deceive and give reason to advance “their guy” Einstein into prominence and push for what Jesuits have always relentlessly pushed for, “relativity” and “relativism”.

this is the experiment that laid the
0:02
foundation for Einstein to develop his
0:04
special theory of
0:06
relativity well actually this is that
0:09
experiment uh it's called the Michaelson
0:10
Morley interferometer and the thing on
0:13
my desk is similar but I made some
0:16
modifications so that I could play it
0:18
like a musical instrument here's what it
0:20
sounds
0:25
like this experiment actually failed to
The original experiment’s impact on physics
0:28
find anything which sounds boring but
0:31
it's actually what makes it super
0:32
interesting and probably the reason it
0:34
won a Nobel
0:35
Prize when I say the ocean as waves I'm
0:38
talking about waves of water when I say
0:41
sound has waves I'm talking about waves
0:44
of air a wave needs a medium in which to
0:48
wave right but when I say waves of light
0:52
what's the medium scientists over like a
0:55
hundred years ago would call this
0:58
luminiferous ether and I don't know this
1:01
for sure but I have to imagine it was
1:03
pretty obvious that it existed because a
1:06
wave needs a medium just like sound
1:08
needs air that's what a wave is it's the
1:10
movement of the
1:12
medium if I was alive back then I'd
1:14
probably skip the Michael morle
1:16
experiment because we know light is a
1:18
wave and obviously it's a wave of
1:20
something it'd be like checking if the
1:22
sky was blue but uh good thing I wasn't
1:25
around to talk them out of it because
1:27
they found out there's no either
1:30
how could that be possible that's like
1:33
saying there's waves in the pool but no
1:36
water it's pretty tricky to describe
1:38
because light is made of something it's
1:41
an electromagnetic wave and there are
1:43
definitely electric and magnetic fields
1:46
but those fields don't need to be there
1:48
in order for there to be a light wave
1:50
light can just travel through
1:51
nothingness if that wasn't freaky enough
1:54
in the same breath the Michaelson Morley
How it led to einstein’s special relativity
1:56
experiment also revealed the speed of
1:58
light is constant regard L of reference
2:00
frame and actually that was the
2:02
discovery that led Einstein to unravel
2:04
our concepts of space and time a common
2:07
way to explain this is to imagine
2:10
throwing a ball on a train if the
2:12
Train's going 10 m hour and you throw a
2:15
ball at 10 mil hour in the same
2:17
direction as the train uh someone
2:19
outside the train would say that the
2:21
ball is moving at 20 M hour if they
2:24
measured it with a cops radar gun that's
2:26
because you're moving at 10 mph and then
2:29
you gave an extra 10 mph by throwing it
2:32
but you would say it's only moving at 10
2:34
mph if you measured it with your radar
2:36
gun because you and your radar gun are
2:39
moving in the same direction as the ball
2:41
just not as fast okay that makes sense
2:44
uh that's called classical relativity
2:46
because how fast the ball is going
2:48
depends on the observer's velocity
2:51
relative to the ball's velocity if
2:54
you're going the same speed in direction
2:56
as the ball you're going to say it's not
2:58
moving okay get ready to have your mind
3:01
completely melted unless you already
3:03
know about this if you imagine the same
3:06
train scenario but instead of throwing a
3:08
ball you turned on a flashlight in the
3:10
direction the train is traveling the
3:13
light would fly from your flashlight to
3:15
the other end of the train just like the
3:16
ball you threw here's the crazy part if
3:19
you measure the speed of that light and
3:21
the person outside the train measures
3:23
the speed of that light you would both
3:25
measure exactly the same speed how is
3:28
that possible
3:30
the person outside the train should say
3:31
that the light is going faster since
3:33
it's being added to the train speed but
3:36
that's just not how light works and
3:38
that's the result that came from the
3:39
Michaelson moley
3:40
interferometer with that information
3:43
Einstein's relativity just sort of falls
3:45
out Einstein was a genius uh no doubt
3:48
but as soon as we found out the speed of
3:50
light was constant someone was going to
3:52
discover special relativity I don't
3:54
think we needed Einstein for
3:56
that the equation for Speed is uh just
3:59
distance over time like uh you know
4:01
miles per hour if we say the speed of
4:04
light is constant no matter what but two
4:07
people say the light traveled two
4:08
different distances in the same amount
4:09
of time that's where we have an issue in
4:13
the train example the person inside the
4:15
train says the light travels the length
4:17
of the train and the person outside says
4:19
it traveled the length of the train uh
4:22
plus however far the train moved in that
4:24
time if both people say the light was
4:26
moving at the same speed but covered
4:29
different distance is there's only one
4:31
variable that can change to make this
4:32
true which is
4:35
time so so time must have been moving
4:38
slower for the person on the train which
4:41
sounds ridiculous but time slows down
4:44
when you go faster uh in reality space
4:47
gets squished and time slows down for
4:49
the person on the train so maybe you
4:51
started this video believing space was
4:53
like a fixed grid and time moves at the
4:55
same speed no matter what but now you
4:58
know both space and time
5:00
uh both Bend to the ultimate master of
5:02
the universe which is the speed of light
5:05
actually if you follow the math it turns
5:07
out if you're able to go faster than the
5:09
speed of light then you might be able to
5:11
reverse the order of cause and effect
5:13
which would completely obliterate my
5:15
last intuition about how the world works
5:17
but luckily the speed of light is the
5:19
speed limit as far as we know okay that
5:22
was a bit of a tangent uh I'll explain
How it uses laser interference
5:25
how these results came from the
5:26
Michaelson Morley interferometer and
5:28
then I'll explain how to turn it into a
5:30
musical instrument first off an
5:33
interferometer is just a device that
5:34
forces light waves to interfere with
5:36
each other which is a super useful way
5:39
to measure really small movement so we
5:42
start by sending a laser into a beam
5:44
splitter which reflects half of the
5:46
light to the right and lets the other
5:48
half through then the two beams we split
5:51
from the Laser Bounce Off a mirror and
5:53
come back to the beam splitter each beam
5:56
gets split one more time but the only
5:58
thing we care about is the light that
6:00
comes out of this
6:02
side so one beam takes this
6:07
path and the other beam takes this
6:12
path which means in this region we have
6:15
two beams superimposed on each other
6:18
when lasers are superimposed like this
6:20
they interfere with each other if the
6:23
two beams line up perfectly they add up
6:26
uh that's what's called constructive
6:27
interference if the beams are completely
6:29
out of phase they cancel each other out
6:32
and that's called destructive
6:34
interference you can actually see the
6:35
light and dark bands where the
6:37
superimposed beams either add together
6:40
or cancel out if we put a light detector
6:43
uh called photo diode uh if we put that
6:46
here we can measure these light and dark
6:48
bands light waves are super small so the
6:51
distance the laser beam has to move to
6:53
go from constructive to destructive
6:56
interference is about a 100,000th of an
6:59
inch
7:00
since one beam travels this
7:02
path and the other beam travels this
7:06
path I can change the length of one of
7:08
these paths and that'll change whether
7:10
the beams interfere constructively or
7:12
destructively and remember I only have
7:14
to change it 100,000th of an inch
7:17
because light waves are so small I can
7:19
just touch it and it'll change and
7:21
actually it can even sense me walking
7:23
around even though I mounted it on a big
7:25
metal cube and suspended it by shock
7:27
cords anyway Michael S morally assumed
7:30
that ether was the stationary ocean uh
7:33
like you can imagine air in a room they
7:35
figured that as the Earth orbits the sun
7:38
it should be moving through this ether
7:40
so they oriented their interferometer
7:42
such that one beam would have to travel
7:44
more in the direction of the Earth's
7:46
orbit than the other the idea was that
7:49
if the ether was moving in the opposite
7:51
direction of the wave it should take
7:53
longer for the wave to get to the
7:55
detector essentially shifting it
7:56
backward then if they rotated their
7:59
experiment so that the other beam now
8:01
has to fight against The Ether impeding
8:02
its movement uh now that one should be
8:05
shifted backwards transitioning between
8:08
these two orientations should change how
8:10
much the two beams interfere with each
8:12
other and that would change the light
8:14
level uh which we could measure with our
8:16
photo diode but as we know the speed of
8:19
light is always constant and there is no
8:21
ether so rotating the experiment did
8:24
nothing okay we can finally talk about
Making it a guitar pedal
8:26
how to turn this into a musical
8:28
instrument the only thing we have to do
8:30
is Mount one of the mirrors onto a
8:32
speaker then when I play my guitar uh
8:35
the path length taken by one of the
8:36
beams is changed by the movement of the
8:39
speaker that means the beams will cycle
8:42
through constructive and destructive
8:43
interference due to my playing and I can
8:46
pick up the light here and output the
8:48
signal as a
8:51
sound one cool aspect of this is how
8:54
responsive it is to Dynamic playing so
8:57
if I play softly the speaker doesn't
8:59
move alone lot so you can imagine one
9:01
wave of my guitar string might
9:02
correspond to going from constructive to
9:05
destructive interference one time in
9:08
that case the input and output should
9:09
sound pretty similar it'll just sound
9:11
like a
9:13
guitar but if I play really hard now the
9:16
speaker is moving in and out really far
9:19
that means for every wave of my guitar
9:20
string the beams would cycle through
9:22
constructive and destructive
9:23
interference lots of times now my photo
9:26
diode is picking up a higher frequency
9:28
than what I put into it
9:30
and that means
9:32
overtones so the harder I play the more
9:35
overtones I get and that's it the guitar
9:38
signal is being sent through and
9:40
affected by the interference of light
9:43
and if light didn't behave like a
9:46
wave there would be no
9:48
[Music]
9:56
sound okay so uh let me know if you're
9:59
interested in hearing about how I
10:00
physically made this instrument I'm
10:03
thinking about making that video I can
10:05
also make a video about designing the
10:06
circuit if you're interested in that
10:09
otherwise I'll just end this video with
10:10
a song from my new album opil so you can
10:13
hear the interferometer in
10:15
action it starts with the interferometer
10:18
and then this saxophone like instrument
10:20
called the gitar comes in I'm going to
10:23
make a video that explains all the
10:24
sounds in uh actually all the songs on
10:27
the album and one of those videos I'll
10:29
EXP explain uh what the gitar is and why
10:31
it sounds all wobbly but uh for now just
10:35
enjoy the sounds
