Hawking radiation in semicondoctor's fake black hole and unreal quasiparticle.

Home page
Einstein relativity is false

(Fig.1)  The present physics pursues only unreal concepts = fake black hole and fictional (polariton) quasiparticle

Fake black hole created in semiconductor excited by laser light is meaningless.

The 2nd paragraph of this hyped news (7/29/2025) says
"Hawking radiation is the thermal radiation theorized to be emitted by black holes close to the event horizon"

"As ascertaining the existence of Hawking radiation.. is currently impossible, physicists have been trying to identify physical systems that could mimic aspects of curved spacetimes (= fake black hole )"

Sound wave cannot escape from supersonic wave = like fake black hole from which light wave cannot escape ?  ← nonsense

The 2nd paragraph of this site on the same news says
"The researchers directed a laser beam at a set of layered semiconductors (= Not real black hole ) sandwiched between two mirrors. The beam’s photons coupled to electron–hole bound states in the semiconductors, forming hybrid light–matter quasiparticles called polaritons. These quasiparticles collectively acted like a fluid of light that flowed within the semiconductors.."

"..By manipulating the beam’s spatial profile, the team created an artificial horizon (= fake black hole ) where the flow speed transitioned from being slower than the speed of sound to being supersonic. Sound waves that naturally formed in this fluid could not escape from beyond the horizon, in analogy with a black hole's horizon. "

↑ So this research tried to treat semiconductors illuminated with light causing supersonic wave (= fake event horizon ) as an fake black hole (= sound wave cannot escape from the supersonic wave like light cannot escape from a black hole ), which fake black hole is useless with No physical meaning.
