Gravitational Lensing of Distant Objects by Closer Galaxies Indicates That

question 48

• A) amount of visible matter in the galaxies accounts for only 10% of the total mass producing the lensing.

• C) amount of visible matter in the galaxies is sufficient to account for the gravitational lensing.
• D) total mass within the galaxies that produces the lensing exceeds the amount of visible matter by a factor of 100.
