The quasars

[saturno2]

It was noted that quasar 3 C273 had redshift of 15.8%
and was moving away relative Earth, at a speed
of 47,000 Km/ sec.
Putting aside for a moment the theory of metric
space expansion.
How is it that such a large object as a quasar,
can travel at high speed of 47,000 km /sec
without desintegration.

Ask yourself what might be there to disintegrate it? It is not the only thing moving. We are also moving away from it at a very high speed. It is like a car on the freeway. Next to the other cars, you don't move that quickly. If there is a stationary wall to hit, suddenly you realize how fast you were moving. Luckily there are no walls in space.

Quasars are at the centers of very distant galaxies. This quasar's whole galaxy is moving away from us at that speed due to the expansion of space. As quasars are caused by Supermassive Blackholes, in a quasar's local galatic frame of reference it would be barely moving, if at all, but the rest of its galaxy is orbiting around it.
