Quizplus · Accepted Answer

Current theories in physics, such as quantum mechanics and general relativity, are not yet reconciled into a single theory, which makes it difficult to describe what happened during the Planck era. This era is when the universe was incredibly small and hot, putting it in the realm of both quantum mechanics and general relativity.
