noun
loop quantum gravity; LQG
Technical term in theoretical physics; a quantum theory of gravity that attempts to merge general relativity with quantum mechanics.
ループ量子重力理論は、時空そのものが量子化されていると考える。
Loop quantum gravity posits that spacetime itself is quantized.
Superstring theory is another major approach to quantum gravity, but it posits one-dimensional strings rather than quantized loops of spacetime.
Calque from English 'loop quantum gravity'. The term combines ループ (loop), 量子 (quantum), 重力 (gravity), and 理論 (theory).
