Hi, I have a question about a fact that I did't understand, and all the world takes this as it is: How can the space-time distortion, generated by gravitational waves, can be measured? All scientist say that the space is stretched and squeezed, but how much means that, because 1 meter stretched is equal with 1 meter squeezed. I saw a documentary on youtube that said if a collision between 2 neutron stars near Earth (theoretically), will generate gravitational waves that will destroy the Earth. How? at atomic level, breaking the bond between atoms..., this means that the strong and weak nuclear forces or electromagnetic forces are independent from space-time fabric? Thanks.
