The High Redshifts Seen for Quasars Could Also Be Interpreted

question 285

Multiple Choice

The high redshifts seen for quasars could also be interpreted as nearby objects with high Doppler shifts caused by rapid motion.Why has this interpretation generally been rejected?

• A) These velocities would exceed the speed of light.
• B) The relativistic mass increase and length contraction for objects at these speeds would result in densities that would make these objects black holes-and they would then be invisible.
• C) Such motions through the interstellar gas in a galaxy would create a huge outburst of X rays, and this is not seen.
• D) Such motions would be large enough to make these objects no longer bound to their galaxies.
