| Absolutely fascinating. Detecting ripples in the fabric of space

| 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.

| A small amount of matter will escape, both iron nuclei (from the
