Question

Pergunta 15 6 pts Consider the all-sky maps of the cosmic microwave background radiation, as observed by NASA's COBE satellite, that are presented below (A-D). Which of the following statements about these maps are true? Select each true statement (there may be several). A. B. C. D. Map D, showing the primordial fluctuations in the cosmic microwave background, can be considered a "baby picture" of our Universe. O The dipole or "Yin-Yang" shape in Map B results from the Solar System's motion with respect to the cosmic microwave background. Microwave emissions of our own Milky Way galaxy make a visible contribution to Map C Historically, studies of the cosmic microwave background, as shown here, have NOT played an important role in debates over the origins of the Universe. O The cosmic microwave background radiation detected by the COBE mission, and shown in Maps A-D, was emitted when the Universe was about 3 minutes old. The high degree of uniformity of the cosmic microwave background over the full sky, illustrated by Map A, serves as an important argument in favor of the "Cosmic Inflation" model for the origins of the Universe. Even though the cosmic microwave background radiation is constantly present, emanating from every direction across the sky, it is extremely challenging to detect with microwave-wavelength receivers.
