Good catch. I didn't notice. I think I already had the gyro animation pointing to the left and the earth images was cut off on the left. So I had to move it to right and then flip it so no not show where it is cut off.

You lost Magnetic interaction with the earths magnetic field when it it was made a superconducter. Should have just use the electrostatic charge on the sphere for measuring drift. I don't believe this experiment is valid because of the magnetic interaction. Also could have use optical interference (inferometer Sagnac effect). "The Sagnac effect, also called Sagnac interference, named after French physicist Georges Sagnac, is a phenomenon encountered in interferometry that is elicited by rotation. The Sagnac effect manifests itself in a setup called a ring interferometer or Sagnac interferometer"

Very informative and thorough. One fact I had learned about the quartz spheres, is that they were manufactured in hemispheres. When the halves were brought together, the matching faces had been machined so perfectly that they immediately bonded atomically.

I don't know man.... We don't even know if particle is a wave or if the wave is a particle. This seems like shooting bullets into the ocean to find out 😂 In all seriousness though. Great presentation. I'm curious how they supported the gyro rotor during the launch of the probe. No way electrostatic forces could overcome such intense linear acceleration. Or am I wrong?
@ReflectiveLayerFilm 13 күн бұрын
Good question. Maybe electrostatic can be strong enough. One thing I forgot to say in the video is the sphere shouldn't touch anything when it's spinning. So it could be safe if it's well supported during launch, then the electrostatic kicks when in orbit and finally the helium jet spins it.

The precision that can be applied to these types of sensors is astonishing, to say the least. The only problem I have is when the scientists feel the need to introduce 'modeling' into the answer to correct for variability. Modeling is a specious approximation, in my opinion, and the freedom used to apply the math is questionable.

I wonder why they didnt make the sphere out of silicon… like how they just changed the kilogram standard to a perfect sohere of silicon. And i think it’s practically atomically perfect.

It'd be better just to use many sub-perfect gyroscopes, and test if their deviations statistically support frame dragging. This design's complexity introduces multiple points of potential failure. For example, eddy currents induced within the coating could undermine confidence in the results. A statistical test would be more robust and provide measurable confidence. Anyway, excellent video!

Page 1:42 that frame dragging is a fancy term for Aether drag. Aether is an incompressible fluid that filled all void space in vacuum of universe. Aether has no mechanical but electrical property, by which vacuum permittivity and permeability are its attributes. As it attached to all matter it “drag” and move in equal velocity with matter in the near field, also drift with another velocity in the far field or deep space a velocity in average to all matter in the universe, hence the term “fluid”. A rough analogy is the harbor current versus ocean current or deep sea current. Also if you don’t mind, gravity, inertia and centrifugal forces are also attributes of Aether. Unfortunately it has been foolishly dismissed from the science community.

I remember seeing the video on the menu who put this project together. This was a long project that took place over outlasted the lifetimes of its original project creators. I think one of the original creators sons got someone to finance the final stage of the project that started when he was a child to honor his dad's death.

You started out by mentioning how important it is that we have well-designed instruments. When you described the perfection of the sphere and how it's important for the sphere not to come into contact with anything(right?), this raised a huge question in my mind. How do we actually manufacture the sphere and then somehow keep it perfectly safe until it was(somehow) integrated into the gyroscope? How did they assemble the gyroscope without touching this delicate little ball? How did the gyroscope actually survive being launched into space on a rocket? **Criticism: Creators of educational Scientific media always seem to fail to anticipate questions like these. I have to assume all these things were solved by unnamed nerds in the backrooms of NASA. Too bad we'll never know who those nerds are because I'd love to ask them how they got their jobs, and what other genius-level issues they've dealt with that we'll also never know about. Do they think these things are just too technical to explain? Or maybe no one is allowed to talk to these people because they're such a high-value human resource, they can't be identified publicly as a matter of National Security?
@ReflectiveLayerFilm Ай бұрын
Good questions. While I can't answer all the questions I will try to answer them to the best of my knowledge based on info that's publicly available. As far as the sphere not coming into contact with anything, that's only true after a certain point in the time. The following are my assumptions as to the way it could have been done(couldn't find any info online). After the Niobium coating was applied, the sphere is measured one last time and carefully placed in the housing inside a clean room. When I say carefully I mean keeping the contact force to the absolute minimum required to move the sphere. Once inside the housing and the housing is placed inside the liquid helium tank, the sphere is cooled and the electrostatic suspension is activated. The spacecraft is now ready to be transported from the lab to vehicle assembly building and then to the launch pad and then to space. Once in space and on the proper trajectory it will be spun to the required RPM. The issue is not necessarily the sphere coming in contact with something but coming in contact with something at 4000 rpm. All questions are good questions and we are learning together as a community. If I don't go into detail about certain aspects of a mechanism it's most likely due to time constraints on the Video(<30minutes). I will however gladly answer questions about those details to the best of my knowledge and of course if it's not time consuming.
