QUESTION 11Why can you not observe beyond the horizon distance?O Because of opaque gasO Because our telescopes are not powerful enoughO Because light/information cannot travel faster than the speed of lightO Because of the presence of black holesQUESTION 12According to the Olber's Paradox, the night sky should be completely bright. However, when we observe at night, the sky is dark. Why does this happen?O Because the universe has a finite ageO Because as the universe expands, objects at larger distances move faster, and the light from them shifts out of the visible part of the electromagnetic spectrumO Both a) and b)O Neither a) nor b)

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Part A Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). The star-gas-star cycle will keep the Milky Way looking just as bright in 100 million years as it looks now. This statement does not make sense. The blowouts of gas from the disc will deplete the gas from the disc of the Milky Way in abiut 10 million years This statement makes sense. Disk of the Milky Way consist enough gas to sustain a few billion years of star formation. This statement makes sense. Most of the bright stars of spiral arms have light expentancies significantly greater than 100 million years. This statement does not make sense.

Your friends are talking about Olber's Paradox: Friend 1: When the universe was quite young, it was also quite small, and therefore light was trapped inside the universe. This is why we don't see light from the edge of the universe in every direction. Friend 2: No, Olber's Paradox describes only light from stars, not from galaxies, and why you can't use light from distant stars to see at night. Friend 3: You're both right and you're both wrong. The paradox concerns itself with the expansion of the universe, and explains why light from the early universe was able to be released. Are any of them right, in part or in whole?

Which of the following is least reasonable regarding the "water hole"? Group of answer choices It consists of frequencies which are greater than the frequencies of atmospheric emissions. It relates to the natural frequencies of vibration of hydroxyl (OH) and hydrogen (H), respectively. It occurs in that part of the electromagnetic spectrum where the galactic "noise" from stars and interstellar clouds is minimized. It is considered the "electromagnetic oasis" for interstellar communication. It corresponds to wavelengths in the 18-21 cm range.
