How LIGO Detects Gravitational Waves | Incredible Interferometer At Home

This is super interesting!

If the changes is smaller than protons, so the wavelength is too long, even if using gamma ray. How it's possible to detect by phase shift of long wavelength?

Thank you for the demo -- it's quite intuitive, Chris!
So, LISA will be orbiting around L5? How stable will they be? What propulsion may be necessary?

I'm actually reading one of Janna Levin's books called Black Hole Blues. She explains the history of LIGO and the years that went into the concept and its construction. This is a remarkable invention and feat they pulled off.

I still dont understand it. :( I am so dumb :(

I thought I understood LIGO (I did at the basic level) but the way you described it was perfect and helped me understand it even more!

If both the space and light are stretched and contracted by GW, the how to measure the difference?

Ilike Youre Little example

They recorded the sound that day . If we make a recording of it over and over and play it can we make a hellium balloon move up and down by turnning a speaker up and down ????

The thing is a fraud, run, tested and vitrified by the very same people that have an interest in it being funded. At best, at best, it can retrospectively look at its data after other detectors (visual or radio) note a large gravitational event has occurred. As noted in your video, the nigh on impossible task of detection is indeed impossible with a device so small for tasks involved.

now that the existence of GW is shown, what's the purpose of looking for more? a detection doesn't help us find exactly which mass caused it. so what's the point?

You haven't explained how GW and laser make interactions

amazingly demonstrated and explained!! Thank you!!

What is the angle you placed the mirrors and laser sir

Hello from Kazakhstan. The Dark Universe requires a lot of money from the budget: an experiment that sheds new light on the Universe will help save costs. We can create an educational and practical device and practically master Einstein’s theories of relativity or obtain, for example, new physics: Postulate 1. Light is an ordered vibration of gravitational quanta. Postulate 2. The gravitational field controls the frequency and speed of light in a vacuum.
This is determined experimentally using a hybrid fiber optic gyroscope (based on Michelson's experiment 1881-2024). Using a hybrid fiber optic gyroscope, the straight-line speed of vehicles can be measured. There is a company in China that makes (fiber optic angular velocity meter) they will be able to create a hybrid device. Please, can you come to an agreement with them? I guarantee payment at cost on my part.

very good explanation

What if there is an earthquake?

It's a simple reflection ("diffraction") pattern coming from the laser's aperture, and then diverged by a lense. It's got absolutely nothing to do with imaginary wave interference. Light waves do not exist. Gravitational waves do not exist. Einstein said so Himself. LieGO is a fraud.

Unfortnately you failed to mention a critical piece of LIGO, without which it simply could not reliably detect gravwaves: there are two complete LIGOs, separated by thousands of miles! It is only if BOTH detect gravwaves essentially simultaneously that we can say with virtual certainty that we have detected gravwaves.

Is that magnifying galss between beam and spliter ??

What is that between laser and beam splitter?

Please reply sirrr

Many thanks. My students will love this.

New technologies are testing the size of the Universe. Through DIRECT physical experiments to test the constant speed of light. Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure +reference distance 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope fiber optic 500‡2». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)”  where - the light travels 500000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 94/94/94 cm, and the weight is 94 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions.

Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: 

Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,...
