Thanks for your comment and question!
Gravitational wave detection won't provide this kind of information as this is not connected to the detection of light. However, there is no reason to be so desperate. There is so much information buried in the light populating the cosmos. The only complication consists of the detection. We are designing sophisticated methods for that, and in addition, every single measurement needs to be double-checked independently. We are now in the process of waiting for the independent confirmation.
To be honest, I don't see how studying anything different from light could help here. By definition. I am however open to any suggestion :)
Thank you for your kind answer. Yes you’re right! Gravitational waves are not related this kind of studies. But suggestion of such a novel technology is not easy as you see. The light itself is the best information package for us to figure out what has happened in the universe and will happen (thanks to spectral analysis). We will be developing more reliable measurement methods based on light detection in the future maybe. Desperation comes from the fact that I am not an anticipation-lover kind of person to see the exact results 😊
I have never said it was easy. I don't foresee anything myself.
I am pretty confident that we will. Maybe not on a 4-5 years timescale, but on a couple of decades, this is clear. There are plenty of experiments being currently proposed, designed, etc.
Ahah I see :)
