If I’m not being pushed from behind, then there is no pushing force.

How is weight a pushing force? Is something pushing me down from above?

I have not seen such instance. When does this happen?

Is there any instance where pushing doesn’t come from behind?

Well, a pushing force comes from behind, does it not?

You seem to have misunderstood my question

Right but what is causing that weight to push townward?

That’s an interesting take. Where is the push force coming from?

You’re describing weight as a pulling force, are you not?

Something like that! But take a closer look at the study to see how these nanoparticles were actually inserted into the brain:

https://www.sciencedirect.com/science/article/pii/S0168365915001376?via%3Dihub

Microvascular clips were applied to the CCA and the proximal parts of the ECA and ICA, and an incision was made between the ECA ligation site and the ECA clip. A 32G catheter (SAI, Illinois USA) was inserted into the ECA towards the CCA then the ICA while removing the microvascular clips. The distance between the middle cerebral artery (MCA) and the bifurcation between ECA and ICA is about 2 cm. Once the catheter was in place, an average of 60 μL poly(maleic acid-co-olefin) or PMO-coated MNPs (concentration: 12 mg Fe3O4/mL double distilled water) was slowly injected. After injection, the catheter was slowly retrieved and the ECA was permanently occluded to avoid excessive blood loss. The animal was then kept alive under anesthesia for 30 min.

This isn't something that's just shot into the bloodstream. It needed to be placed in a precise location to trigger the proper brain channels to be affected by the frequency. The whole point I'm making about the impossibility is that something just injected and passively floating through the bloodstream wouldn't be able to function in the way that's being described.

My question is why is it down towards the earth? If you do not know, that’s a perfectly acceptable answer

So what causes weight to be a property that brings objects toward the earth?

Find me any instance of such tech then. Because right now you’re just showing me that you’re purely speculating based on sci-fi plot points.

Do you have any data? Facts to back up what you’re thinking?

So gravity is a downward force? What causes it?

Yes, a sci fi book. Science fiction.

It’s interesting as a concept, but it’s not possible in practical application. That’s why there’s only fiction.

Blake Crouch has a couple of great well researched books on breaking into alternate realities. It’s still not possible in the real world

If they do, they’ve used regular ass manufacturers to make components of it. That’s what government contract jobs are. If it were possible, there would be worse versions available.

Again, I know it seems like a fun sci fi thought, but it’s technologically not possible.

If you can find me a device that does anything close to what you’re suggesting, feel free to show me and I’ll eat my hat live on camera in front of you. You can’t though, because the tech is not available to anybody.

Well for one, I’m an engineer by trade, working in both sensor technology and wireless data transfer, so it’s part of my job to stay up to date on things like that. More importantly, I’m familiar with what is possible and what isn’t as it pertains to this sort of tech

Secondly, I know manufacturing. If there’s a state of the art technology, such as a nanochip that can be injected and activated by a remote frequency after staying dormant for a number of years, then there would have to be prototypes. Prototypes would be tested, evaluated, and seen by similar companies trying to do the same thing. There would be imitation/competing devices all over the world by people who are trying to do it first.

It’s an interesting sci-fi scenario, one explored briefly in the Kingsmen movie, among others. But from a technical standpoint, it just isn’t possible in the way you are suggesting

I’ll give you a hint: this sort of technology that you’re suggesting isn’t possible

And where has anything like this happened before?

And what sort of devices are those? Devices that can be injected into the body?

It’s not a nonsensical question. There must be a reason why objects would go toward the earth and not away from it.

I studied sound frequencies. The scenario you described seems incredibly far fetched

Is there any instance of something like this happening elsewhere?

Seems incredibly far fetched.

Nothing seems to have happened

Concave wouldn't look like a perfect circle from every angle

Why should they?

I think that's the inherent question. Why is it towards the earth, and not outward?
