Is There Life Elsewhere? After considering all the evidence to date about the possibility of extraterrestrial life, do you believe it is likely that we'll find microbial life elsewhere? Do you believe it is likely that we'll find intelligent life elsewhere? Defend your opinions, using arguments based on the full range of scientific issues discussed in this book.
If microbial life is possible elsewhere and chances of intelligent life.
Answer to Problem 1DQ
There is a possibility of existence of microbial life elsewhere due to common elements around universe and also various conditions on earth indicates similar condition in universe making human belief for possibility of microbial life. Intelligent life is also possible in universe.
Explanation of Solution
There is a great possibility of microbial life in universe.
Various evidences for such possibilitiesare as follows:
- The elements that are found on earth are very common in universe and carbon molecules which help in life formation can also be formed easily.
- Life on earth was possible even under harsh conditions which were supposed to be harmful. All these adverse condition made life adaptable to the changes in them with changing condition. These similar conditions are common in all over universe with less variation which makes humans belief that life can exist in universe.
- Earth became habitable after long time of formation of universe. This makes it evitable that there might be other planets too that had life on them.
According to the books it is believed aliens would be much advanced from human civilization. They will be intelligent and more superior. Some books even suggested aliens would come to help and solve problems of human.
Conclusion:
Thus, There is a possibility of existence of microbial life elsewhere due to common elements around universe and also various conditions on earth indicates similar condition in universe making human belief for possibility of microbial life. Intelligent life is also possible in universe.

- Hi can u please solvearrow_forward6. Bending a lens in OpticStudio or OSLO. In either package, create a BK7 singlet lens of 10 mm semi-diameter and with 10 mm thickness. Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function.
