Vor einem Tag · This discrepancy was corrected by Einstein's theory of special relativity, which replaced classical mechanics for fast-moving bodies and allowed for a constant speed of light. Black-body radiation provided another problem for classical physics, which was corrected when Planck proposed that the excitation of material oscillators is possible only in discrete steps proportional to their frequency.
Vor einem Tag · Using 300,000,000 km for the diameter of Earth's orbit, calculate the speed of light based on Roemer's 1300-s estimate. How does it differ from a modern value for the speed of light? c = 2.31×105 km/s cR/cm = 0.77
Vor einem Tag · If the Sun were to cool off dramatically and as a result start giving off mainly light at wavelengths longer than visible light, how would the frequency, energy, and speed of this light given off by the Sun also be different? Explain your reasoning.

If we say that a galaxy has a lookback time of 1 billion years, we mean that _________. its light traveled through space for 1 billion years to reach us. Current estimates place the age of the universe at about _________. 14 billion (giga) years.
