The phase coherence of light from extragalactic sources - direct evidence against first order Planck scale fluctuations in time and space
Richard Lieu, Lloyd W. Hillman
We present a method of directly testing whether time continues to have its usual meaning on scales of <= t_P = sqrt(hbar G/c^5) ~ 5.4E-44 s, the Planck time. According to quantum g…

Stringent limits on the existence of Planck time from stellar interferometry
Richard Lieu, Lloyd W. Hillman
We present a method of directly testing whether time is `grainy' on scales of <= t_P = (hbar G/c^5)^0.5 ~ 5.4E-44 s, the Planck time. If the phenomenon exists, the energy and momen…
