(Fig.1) Higgs, quark .. are unreal, virtual only inside collider.
This paper claims they can treat some "vibration" of superconductor as a sign of "imaginary" Higgs, which cannot be detected directly.
Different from real particles such as electrons, Higgs and quarks lack reality, they are too unstable and too rare to confirm.
We cannot separate Higgs from infinite irrelevant particles inside collider, which means Higgs is "virtual" only inside collider.
Unless you can isolate pure Higgs and quarks from other irrelevant particles, these particles aren't real particles, of course, useless.
(Fig.2) ↓ Light is bent by air, NOT Einstein gravity. 
This study claims they can measure the mass of very distant star using Einstein lens where the emitted light may be bent by gravity.
But this claim is scientifically very unreliable. It's impossible to distinguish gravitational effects between visible matter and hypothetical dark matter.
Furthermore, space dusts and "air" have much "stronger power" to bend light than their doubtful Einstein gravitational lens.
We can observe the light is strongly bent by the air due to classical light refraction. Light refraction is far stronger than gravitational lensing ( > 1000 : 1 ) !
Einstein relativity cannot explain light refraction, so they ignore it. Light deflection is not by general relativity but by classical theory.
Test of Einstein theory is targeted at stars too far away from the earth, they are kind of "scam", because we cannot go to confirm them.
