Favorite Quotes from Life in the Universe Essays:

— Travel —

Every term, each student in my Astronomy 115 course (Life in the Universe) was assigned to write an essay giving his or her opinion on the following question:

"Do extraterrestrial technical civilizations currently exist in our Galaxy?"

This group of quotes concerns interstellar travel. (The typos and misspellings are real, but they are not mine.) The material is presented here without comment; you will have to make up your own.

    Essay Quotes: Travel

  1. If they did exist in our galaxy they would have to be able to move around pretty fat otherwise be very far out in the galaxy so that we would discover them. One way that we have been trying to find them is by using radio waves which in due time, I think that we will probably have some luck.

  2. Yes, we have been able to travel to the moon and travel to Mars, but I feel that when you crunch the numbers relating to space travel, you come up way to short, and that goes the other way around also.

  3. While looking throughmy astronomy book, I read that aliens have visited earth.

  4. After taking this class you understand time travel and how it is impossible at this stage to examine or "visit" all of the stars in our galaxy let alone in the Milky Way.

  5. Another problem that we run into is the concept of space travel, if the laws on this planet apply to the rest of our galaxy, then there's no known way to reach another life harboring planet in the time it would take to reach it given the circumstances. The circumstances the being the fact we assume life will resemble ours, in the way that everything must eventually deteriorate and turn into different compounds.

  6. Another reason I believe in current extraterrestrial civilizations is space travel. Although it takes a long time to travel to the nearest star and the Milky Way, it depends on the speed. I think alien bodies last as long as humans and since it is possible to travel the distance in 10 years, we know the human body lasts that long and therefore it is possible there is extraterrestrial civilizations in out Galaxy.

  7. We are unable to travel in light years. So, to travel past our galaxy is going to take even longer then stated.

  8. There is a very unlikely chance, in my opinion, other Extraterrestrial life has developed space travel so advanced that they can travel faster than the speed of light even though traveling faster than that is not possible.

  9. Many people believe that extraterrestrials have already traveled light years of the galaxy and made their mark on us.

  10. If even one of those 23 civilizations has evolved to a more advanced species then us they may be able to travel to earth and be unseen except for the people that have been abducted.

  11. Technology is the greatest hold back for space exploration, since space travel takes such large increments of time, we would have to make up for it in technology and become a civilization similar to Star Wars. The glory of space is unmatched in movies however I just can't get myself to think it is possible to live floating in space.

  12. Having the ability to travel at such speeds of light speed can be considered impossible.

  13. Scientists have perfected space travel but have not been able to have humans travel past our moon.
