Objects are falling to the floor because the room is aboard a rocket in space, which is accelerating at 9.81 m/s2 and is far from any source of gravity.
Chimonas (1970) was the first to report that a sudden cooling effect could act as a potential source of gravity waves that are likely to propagate upwards, even into the thermosphere, when the source mechanism changes rapidly.
If confirmed, the result suggests that magnetar collisions could be a common source of gravity waves.
When slabs are not modeled, the self-weight of slabs (a significant source of gravity loading on buildings) and additional live loads should be distributed on beams.
This close correlation suggests that in situ wind shear may be a major source of gravity waves and turbulence in the MLT.
In the 1970s, his atomic clocks were flown around the world to prove parts of Einstein's general theory of relativity — the idea that time does slow down when you move closer to a strong source of gravity.
The katabatic winds as a branch of Antarctic tropospheric circulation and as an important source of gravity waves are also of special interest.
It is, as Leigh points out, a natural literary subject, a source of suspense and gravity, with drawn-out ceremony and decisive closure built in.
Nakamura et al. (1988) and Taylor and Hapgood (1988) also identified thunderstorms as a source of short-period gravity waves.
