New Method Proposed for Detecting Gravitational Waves Using Atoms
利用原子探測重力波的新方法
For years, observing gravitational waves meant building massive structures like LIGO, which uses kilometer-long arms to detect ripples in spacetime.
多年來，觀測引力波意味著要建造像LIGO那樣的巨大結構，利用長達數公里的手臂來偵測時空中的漣漪。
Now, scientists are turning to quantum physics, exploring ways to detect these cosmic waves using atoms instead of giant mirrors.
如今，科學家轉向量子物理學，探索利用原子而非巨型鏡面來偵測這些宇宙波。
A groundbreaking proposal from 2026 suggests that gravitational waves might shift the frequency of light emitted by excited atoms.
一份2026年的開創性提案指出，引力波可能會改變受激原子發出光的頻率。
Meanwhile, another field called atom interferometry is already further along.
與此同時，另一個稱為原子干涉測量法的領域已經進展得更遠。
By splitting an atom's wavefunction and recombining it, researchers can detect gravitational waves through shifts in interference patterns.
透過分裂原子的波函數並將其重組，研究人員可以經由干涉圖樣的變化來偵測引力波。
Unlike LIGO, these quantum-based methods offer immunity to certain types of laser noise and could capture frequencies in the 'infrasound' band—between 0.1 and 10 Hz—which current facilities struggle to observe.
與LIGO不同的是，這些基於量子的方法對某些類型的雷射雜訊具有免疫力，並且可以捕捉「次聲波」(ㄘˋㄕㄥㄅㄛ)頻段（介於0.1到10 Hz之間）的訊號，這是現有設施難以觀測的領域。
Scientists must still find ways to shield these delicate atomic systems from environmental noise to confirm if we can truly 'hear' the universe through the quantum dance of atoms.
科學家仍須設法保護這些脆弱的原子系統免受環境雜訊的干擾，才能證實我們是否真的能透過原子的量子之舞來「聽見」宇宙。
