       | Absolutely fascinating. Detecting ripples in the fabric of space
       | and time? The NSF is still producing Nobel worthy discoveries.

       | I've been working on a Deep Convolutional Generative Adverserial
       | Network (DCGAN) which utilizes astronomical data and have been on
       | an astronomy kick.
       | 
       | Cutting funding to pure science research is a profound mistake,
       | pure science research puts our nation at the forefront of
       | technological discovery and is of national strategic importance.

       | Not whole.
       | 
       | A small amount of matter will escape, both iron nuclei (from the
       | crust) and free neutrons.
       | 
       | The R-process of stellar nucleosynthesis will then take place.
       | 
       | As I understand it, a normal output between three and 13 earth
       | masses of gold is typical.
       | 
       | This total mass is insignificant compared to the final mass of
       | the combined object, but it is also the engine that creates many
       | elements higher than iron on the periodic table.

       | already struggling with just doing classical N-body accurately!
