The Cosmic Microwave Background (CMB) radiation is currently detected as low-energy microwave radiation. Which of the following provides the best explanation for this observation?
True or False: Before modern astronomical observations, the scientific consensus was that the universe was static and that galaxies occupied fixed positions relative to one another.
In the context of the Doppler effect for light, what specific change occurs to the properties of a wave when the distance between the source and the observer increases?
What significant transition occurred in the early universe approximately years after the Big Bang that allowed for the eventual detection of the cosmic microwave background (CMB) radiation?
Which analogy best describes how galaxies move apart in an expanding universe without a central point of origin?
Using Hubble's Law if a galaxy is moving away at a speed of and the Hubble constant is , how far away is the galaxy?
The Cosmic Microwave Background Radiation (CMBR) is remarkably uniform, meaning it is detected with nearly the same intensity from all directions. What does this uniformity suggest about the early universe?
A specific spectral line from a stationary source in a laboratory has a frequency of . When observing the same line from a distant galaxy, an astronomer measures a frequency of . Based on the wave relationship , what is the percentage change in the wavelength of the observed light compared to the source light?
For an observer on Earth, light from a distant galaxy is found to have an observed wavelength of . If the original emitted wavelength is , and the galaxy is moving away, which relationship is correct?
When observing light from a distant galaxy, astronomers notice that the light waves are 'stretched' to longer wavelengths. According to the Doppler effect, what physical mechanism causes this stretch?
