Question

clara made a chart to summarize some of the evidence that supports the big bang theory. evidence for the big bang theory category of evidence description redshift light source and observer move farther apart light observed shifts to a longer wavelength indicates receding galaxies cosmic microwave background radiation (cmb) red - shifted to the microwave region temperature much higher now than at time of big bang which best describes claras error? during redshift, the light source and observer move closer together, not farther apart. the cmb is blue - shifted, not red - shifted, to the microwave region. the temperature of the cmb is cooler, not hotter, than at the time of the big bang. the redshift indicates approaching, not receding, galaxies.

Explanation:

The Cosmic Microwave Background Radiation (CMB) is a remnant of the Big - Bang. The universe has been expanding and cooling since the Big - Bang. So, the temperature of the CMB is cooler now than it was at the time of the Big - Bang. Clara's error is stating that the temperature is much higher now than at the time of the Big - Bang.

Answer:

The temperature of the CMB is cooler, not hotter, than at the time of the big bang.
