Object: Rigidity versus SR: "sound faster than light"
The rigidity -- gas pressure -- in some stars becomes so great that the
speed of sound would be greater than c.
Imagine the outcry on these groups if someone said the kinetic energy
of some 1kg masses is so great that they would go faster than light!
The situation in neutron stars saved by general relativity, not the
special theory (though Einstein would not have been happy with it):
when v(sound) = c, complete, irresistible (like me) gravitational
collapse occurs.
Einstein knew that rigidity was difficult to fit into SR, and it
concerned him in the first years after his annus mirabilis ....

The rigidity -- gas pressure -- in some stars becomes
so great that the speed of sound would be greater than
c.

The gas pressure can become so great that gas becomes solid. And
the speed of sound in a solid is << c.

Imagine the outcry on these groups if someone said the
kinetic energy of some 1kg masses is so great that they
would go faster than light!

Even matter at 25 million degrees K is not moving all that fast,
pressure or not. Pressure only deals with distance between mass
centers.

been happy with it): when v(sound) = c, complete,
irresistible (like me)

Good to know you won't be breeding.

gravitational collapse occurs.

Demformable solid behavior was very well known centuries before
Einstein. He had no problems with it.

Gribbin and Davies said it in The Matter Myth. So it must be true.

It's clear you have none.

False.
