在早期宇宙中，天文學家偶然發現了一個宇宙謎團：存在著遠超其年齡應有大小的超大質量黑洞（SMBH）。
In the early universe, astronomers have stumbled upon a cosmic mystery: the existence of supermassive black holes (SMBHs) that appear far too large for their age.
詹姆斯·韋伯太空望遠鏡（JWST）在宇宙大霹靂後僅4.5億到7億年就觀測到了這些巨型黑洞，它們挑戰了我們現有的星系演化標準模型。
Observed by the James Webb Space Telescope (JWST) just 450 to 700 million years after the Big Bang, these giants challenge our standard models of galaxy evolution.
根據傳統理論，黑洞是透過吞噬氣體或與鄰近黑洞合併而逐漸生長的。
According to traditional theories, black holes grow gradually by consuming gas or merging with neighbors.
然而，這些「過度巨大」的黑洞似乎跳過了這種緩慢的生長過程，在極短的時間內就達到了數十億倍太陽質量。
However, these 'overmassive' black holes seem to have bypassed this slow growth, reaching billions of solar masses in an impossibly short timeframe.
這就像一個幼兒突然在一夜之間長到了職業籃球運動員的身材。
It is like a toddler suddenly growing to the size of a professional basketball player overnight.
為了解開這個謎題，研究人員提出了新的理論。
To solve this puzzle, researchers are proposing new theories.
其中一個理論提出「直接坍縮」機制，即巨大的氣體雲瞬間轉變為黑洞。
One suggests 'Direct Collapse' where massive gas clouds instantly turn into black holes.
另一個理論探討了「自相互作用暗物質」，這可能會加速重力坍縮。
Another explores 'Self-Interacting Dark Matter,' which might accelerate gravitational collapse.
此外，還有一種可能是起源於大霹靂之後立即形成的「原始黑洞」。
There is also the possibility of 'Primordial Black Holes' born immediately after the Big Bang.
