As the paper suggests, there are other ways to make these detections. LISA on the other hand searches for low-frequency gravitational waves that will never be detectable by any terrestrial detectors, existing or planned. These low-frequency gravitational waves cannot be detected on Earth because...
No they're not "holes" but appeared to express the properties of a hole when they were first being discovered. They are just a very large amount of matter collapsing on a relatively small point in space due to the phenomena of gravity. Gravitational collapse occurs when an object's internal...
Clyde Cowan, Frederick Reines, F. B. Harrison, H. W. Kruse, and A. D. McGuire published confirmation in a 1956 issue of Science that they had detected the neutrino, in which they were awarded the Nobel Prize in 1995.

Well you wouldn't hear any sound in the vacuum of space itself, however inside the ship one would still hear all kinds of familiar combat sounds as you're hit, shooting, or even the change in velocity.
