Fill in the blank. a massive body can bend the path of a beam of light as it travels through space; it causes light to travel on a path rather than along a straight line. light waves compress as an object is moving toward an observer, causing the light to shift to the end of the electromagnetic spectrum. black holes can't be observed directly because they don't produce so the location is identified by examining the motion of nearby stars. even less understood than dark energy is dark making up 27 percent of matter in the universe and cannot be observed with light. holding the milky way together is accomplished by the provided by a supermassive black hole near the center of the galactic bulge. respond to the following based on your reading. explain why the galactic disk appears blue and the galactic bulge appears red.

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
