When interest rates are low, consumers and businesses do not just borrow money; they borrow money to buy assets, setting up a feedback loop that can eventually lead to a bubble.

当利息较低时，消费者与商人并非仅仅借贷资金，他们将借来的钱购买资产，形成反馈循环，最终导致泡沫。

他们还借钱购买资产，建立一个反馈回路，可最终导致了泡沫的生成。

Although glowing like an emission nebula, the origin of the bubble, known as Barnard's Loop, is currently unknown.

尽管像发射星云，猎户座的泡泡，为人所熟知的巴纳德环，到现在还有很多未知之处。

Predications are hard, especially about the future, but it seems increasingly likely to me that the feedback loop may not stop, we will see a full-fledged bubble and that it will only be able to end in a meltdown.
