because the P waves move faster through more rigid substances than through non rigid material>

Nope, sounds doesn't travel faster on space because a medium is needed a region to another
Water will travel faster in gravel than sandStudents in secondary school should know this!
Water has a higher density than rock. -Gordon Crocker
by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere. The upper part of the asthenosphere is believed to be the zone upon which the great rigid and brittle lithospheric plates of the earth's crust move about (see plate tectonics). The asthenosphere is generally located between 45—155 miles (72—250 km) beneath the earth's surface, though under the oceans it is usually much nearer the surface and at mid-ocean ridges rises to within a few miles of the ocean floor. Although its presence was suspected as early as 1926, the worldwide occurrence of the plastic zone was confirmed by analyses of earthquake waves from the Chilean earthquake of May 22, 1960. The seismic waves, the speed of which decreases with the softness of the medium, passed relatively slowly though the asthenosphere, thus it was given the name Low Velocity zone, or the Seismic Wave Guide (see seismology). Deep-zone earthquakes, i.e., those that occur in the asthenosphere or below it, may be caused by crustal plates sinking into the mantle along convergent crustal boundaries.

They travel faster through solids
The denser the faster. ie: it will travel faster through quartz than sandstone.
sound travel faster through soled because of tighter packed particles
sound travels faster through steel

Through metals
It doesn't travel faster through a vacuum. In our Universe there is no such thing as empty space.
Waves travel faster through denser materials. However, Electromagnetic waves travel faster through less dense materials. It travels fastest in vacuum.
Light travels much faster than sound, through wood.
it travels faster through air.
Iron is denser than air. Waves travel faster through denser medium.
