A community to discuss space & astronomy through a STEM lens

Rules

  1. Be respectful and inclusive. This means no harassment, hate speech, or trolling.
  2. Engage in constructive discussions by discussing in good faith.
  3. Foster a continuous learning environment.

Also keep in mind, mander.xyz's rules on politics

Please keep politics to a minimum. When science is the focus, intersection with politics may be tolerated as long as the discussion is constructive and science remains the focus. As a general rule, political content posted directly to the instance’s local communities is discouraged and may be removed. You can of course engage in political discussions in non-local communities.

...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
