Using Pulsars to Detect the Background Gravitational Waves

S i did a fairly lengthy interview with one of the researchers working on this, and it's pretty amazing what they've discovered so far. There is now work that is looking for differences in the timing of pulses that are created by the expansion and contraction of space time due to gravitational waves propagating through the universe. And this is where we have to look at two totally different things and get them clear in our head. Is two different things. The original nobel prize given for seeing the changes in orbits of degenerate objects of this neutron star system,. That was seeing gravitational energy that was lost through gravity tonal waves, but not directly seeing the gravitational waves.
