The convergence fluctuation of light by clusters of galaxies - a cosmological test using the second acoustic peak of the microwave background
Richard Lieu, Jonathan P. D. Mittaz
The magnification of distant sources by mass clumps at lower () redshifts is calculated analytically. The clumps are initially assumed to be galaxy group isothermal spher…

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…
