Gravitational Waves detected for the 2nd time

a reply to: TrueBrit

Agree with everything, the youtube video I posted talks exactly about LIGO's lab and how they discovered gravitational waves. "a mere fraction of an atomic diameter"

If guessing if a gravitational wave has no noticeable effect on spacetime then spacetime is much more powerful than gravity?

However I'm wondering if a gravitational wave passing through Earth caused a mere fraction of a diameter of spacetime to squeeze and stretch? How long does it take for the wave to pass completely through our planet? What happens in spacetime at an atomic level? How do atoms react to gravitational waves?

It does have a noticeable effect. That effect is what was measured. Spacetime is not "powerful." It is affected by tiny amounts of matter and energy.

Gravitational waves travel at the speed of light.
The space within the atom (an atom is mostly space) changes shape as the wave passes.

This 3D visualisation is not that great either. It is not showing the bending of time.

The bending? Gravity slows the time down. The video isn't aiming to visualise that.
