…The research team at Cardiff University took a bold step toward understanding the quantum nature of gravity by setting new limits on the existence of very high-frequency gravitational waves…
“Our experiment is trying to answer the question of whether space-time is ‘quantized’,” Abhinav Patra, MSc, a doctoral student in the university’s Gravity Exploration Institute and lead author of the study, stated. “Modern physics treats space and time not as two separate things, but as a single physical entity.”
By correlating data from two independent interferometers, the team ruled out certain high-frequency gravitational waves that might be predicted by quantum theories of gravity.
This correlation method allowed them to isolate potential signals from random noise and effectively filter out local disturbances like seismic vibrations or thermal fluctuations…
Hey that’s fun I never thought of space and time as a single entity.
yeah, its a wild concept to wrap your head around
the further out we look in space, the longer it took for that light to reach us, so its effectively looking backwards through time
