Universal age paradox
Two most straightforward methods of computing the age of the Universe through redshift measurements, and stellar evolution yield incompatible results. Recent (mid 1990s) measurements of distances of distant galaxies by the use of the Hubble Space Telescope mention an age much less than the ages of the oldest stars which we calculate through stellar evolution theory . Currently there is no result to this paradox; a cosmological constant would rectify the condition, but it's possible that the discrepancy will not appear along with more accurate measurements of the age of the Universe by both methods.
Minimum amount of light for low vision If 90 photons enter the eye ,10 or less are actually absorbed in photoreceptors. About 3% are reflected at the surface of the corne
Capacitors in parallel: Three capacitors are connected in parallel. If on closing the switch S a current I flows in the circuit, then from Kirchoff's first law:
It is the distance travelled by the disturbance in single time period. It only relays on the properties of the medium and it independent of time and position.
A more forceful argument which the weak principle: This implies that if the laws of the Universe were not favorable to the development of intelligent creatures to ask regarding the
