Do low interest rates cause asset bubbles? If not, why do so many people in finance appear to believe that low interest rates cause assets to become mispriced?

When interest rates are low the investment money that would normally go into US treasury and other low risk bonds, CDs, and other interest bearing assets, instead needs to move into riskier assets such as equities, real estate, or commodities in order to earn a return. 

This increases the demand for those assets, and if the supply is constrained, the price may rise higher than is warranted by the underlying value of the asset. Often speculators might then come in, seeing rapidly increasing prices, and push things even higher.

As interest rates increase, or speculators get spooked, money can then quickly flow back out of those riskier assets, causing the price to collapse.
