Astronomers Deal Blow To Quantum Theories Of Time, Space, Gravity

From the article Astronomers Deal Blow To Quantum Theories Of Time, Space, Gravity:

That theoretical upper limit was then used to set theoretical limits on time. One cycle of a photon carrying that much energy would last 5 x 10-44 seconds, an interval called Planck time. As the shortest potentially-measurable interval of time, theorists speculated that time moves [in] Planck time-sized quantum bits.
...
If time is made up of quantum bits, that would also mean space and gravity should also be composed of quantum units.

Since the expected blurring "signature" of quantum space time isn't seen, however, it might mean that time isn't made of quantum bits, and neither are space or gravity.
