#3I'm not sure how it's possible to "never touch" a gravitational field given that they extend throughout the universe and are impossible to be shielded.

#4article goes on to state that gravitational pull effects surrounding objects without touching them, you know, like how we already know every fucking planet works?
quantum physics: the biggest waste of time since philosophy

What about the use of quantum physics in things like semiconductors?

semiconductors don't "use" quantum physics, quantum physics just tries to explain how they work. semiconductors still exist without requiring quantum physicists to come in and try and steal credit for something they had no influence on whatsoever.

They touch on that in the article:
> Notably, the particles weren’t in a gravitational field–free zone. Instead, the experiment was designed so that the researchers could filter out the effects of gravitational forces, laying bare the eerie Aharonov-Bohm influence.
I'm no physicist, but I think they calculated the expected influence and compared that with a measurement.

#9Sounds more like a demonstration of an ability to detect the influence of gravitational fields at scales previously unavailable. Specifically, in testing something called the "Aharonov-Bohm influence/[effect]" previously demonstrated within EM fields and now for gravity.

The study not only reveals a famed physics effect in a new context, but also showcases the potential to study subtle effects in gravitational systems. For example, researchers aim to use this type of technique to better measure Newton’s gravitational constant, G, which reveals the strength of gravity, and is currently known less precisely than other fundamental constants of nature (SN: 8/29/18).

It says:
> subatomic particles can feel the influence of this warping even if they aren’t subject to gravitational forces
So I guess they are talking about particles without mass.
